A severity index for epidemiological surveys of female urinary incontinence: comparison with 48-hour pad-weighing tests

Social media recruitment of participants in a female stress urinary incontinence trial: A feasibility study

OBJECTIVE

This study explores the opportunities of social media advertisements as a recruitment strategy in women with stress urinary incontinence (SUI).

STUDY DESIGN

This feasibility study was part of a larger clinical trial on the effects of a patient decision aid for SUI treatment. We started a 61-day social media advertisement campaign to recruit women for the trial. The primary outcome of our study was enrolment pace. Secondary outcomes involved cost per participant, baseline demographic comparison and ad campaign performance metrics. Additionally, we interviewed recruited participants to identify the facilitators and barriers of our approach.

RESULTS

Ten participants were recruited, of whom 8 completed the full study protocol (2 questionnaires 6 months apart). The enrolment pace, 4.0 study participants per month, was faster compared to the average of 2.7 participants per month through conventional methods. The campaign reached 87 clicks on the advertisement per day and 1 % of these women showed interest in our study by contacting us. The overall conversion rate from click to full participation was 0.2 %. The costs per participant were €112. Besides higher age, the demographics of the social media recruited participants were comparable to the conventional inclusions. Qualitative analysis identified more user-oriented enrolment procedures and potential participant benefit as facilitators of social media recruitment.

CONCLUSION

This study shows that social media recruitment can be feasible in trials for women with SUI. It can accelerate recruitment of eligible participants. Optimising the enrolment procedure to better meet participants' needs and recruitment benefits may improve participation and cost-effectiveness. Trial registration ID 2017-3540.

Cognitive function and bladder health among midlife adult women in the Coronary Artery Risk Development in Young Adults (CARDIA) study

OBJECTIVE

The aim of this study was to examine whether different aspects of women's cognitive function are associated with lower urinary tract symptoms (LUTS) and their impact.

METHODS

In 2010-2011, women aged 42 to 57 years in the Coronary Artery Risk Development in Young Adults study completed different tests of cognitive function, including the Digit Symbol Substitution Test, Rey Auditory Verbal Learning Test, and Stroop test. Two years later, data on LUTS and their impact were collected. LUTS/impact, a four-level composite variable ranging from bladder health to mild, moderate, and severe LUTS/impact, was regressed on each cognitive test separately, as well as a cognitive function composite variable. The analytic sample was composed of 1,021 women with complete data.

RESULTS

When adjusting for sociodemographic variables (age, race, education) and gynecologic/obstetric variables (parity, menopausal status, hysterectomy, hormonal use), better performance on the cognitive function composite and Digit Symbol Substitution Test were both associated with lower odds of membership to a more severe LUTS/impact category (odds ratio, 0.90 [95% confidence interval, 0.83-0.98] and 0.89 [95% confidence interval, 0.82-0.97], respectively). These associations became nonsignificant when additionally adjusting for mechanisms that might explain an association between cognitive function and LUTS/impact, including health behaviors and health conditions that may covary with cerebral and peripheral vascular health and cognitive function.

CONCLUSIONS

In this sample of midlife adult women, a modest association was found between better cognitive function and lower likelihood of LUTS/impact. Longitudinal studies are needed to further investigate the association between cognitive function and LUTS/impact, as well as potential explanatory mechanisms, particularly as women age and cognitive function varies to a greater degree.

A theoretical model for brisk walking- and running-induced lower urinary tract symptoms (BRUTS) and the development of the BRUTS-questionnaire (BRUTS-Q): A focus group and Delphi study

AIMS

Existing questionnaires provide limited information on the nature, severity and context surrounding lower urinary tract symptoms (LUTS) experienced during running, jogging and brisk walking. The aims of this study were to develop a theoretical model of the experience of LUTS by females participating in gait-based exercise activities and to use this model to generate a questionnaire to evaluate the presence, symptoms and bother associated with LUTS experienced by females during gait-based activities.

METHODS

A theoretical model was developed through a review of the literature and refined through a focus group consultation including pelvic health physiotherapists, females who experienced leakage during exercise and academic researchers who studied female LUTS. A draft questionnaire was developed using key constructs identified in the model by the focus group. A new expert panel was recruited, which included physiotherapists, women with self-reported gait-induced LUTS and urogynecologists. This panel followed a DELPHI process to evaluate the relevance and completeness of the constructs within the questionnaire.

RESULTS

Two rounds of consultation were required to reach consensus on the completeness of included constructs as well as the inclusion and wording of questions. The resulting questionnaire contains questions related to five key constructs: physical activity characteristics, symptoms of urgency, urgency urinary incontinence, stress urinary incontinence experienced during exercise and management/mitigation strategies adopted by respondents.

CONCLUSIONS

The content validity of the brisk walking- and running-induced lower urinary tracts symptoms questionnaire has been established. The next steps are to ensure that the questionnaire has adequate comprehensibility, followed by adequate measurement properties.

Quality of life following transobturator sling surgery for female stress urinary incontinence

OBJECTIVE

This descriptive study examines quality of life in women undergoing placement of a midurethral sling for stress urinary incontinence.

MATERIALS AND METHODS

This was a retrospective cohort study based on data from 51 women consecutively undergoing this procedure at a tertiary hospital in the years 2014 and 2015. The main outcome variable was quality of life assessed through the Sandvick severity test and International Consultation on Incontinence Short Quality of Life Questionnaire (ICIQ-IU-SF) at the time points baseline or presurgery, and 6 months and 5 years postsurgery. Factors associated with treatment failure were determined through binary logistic regression.

RESULTS

At 5-year follow up we obtained an absolute reduction of 8.78 points (95% CI 6.43-11.14; p < 0.001) in the ICIQ-IU-SF questionnaire and 4.54 (95% CI 3.25-5.83; p < 0.001) in the Sandvick severity test score, compared to baseline, in the 35 patients that completed follow-up. Out of the 51 patients that were followed, the rate of success in incontinence correction was 86.3% (44/50) with a failure rate of 12% (6/50). Multiparity and previous gynaecological surgery were identified as predisposing factors for treatment failure. Obesity was associated with a worse treatment outcome.

CONCLUSION

Sling treatment for incontinence was successful in 86.3% (44/50) of participants and remained effective 5 years after surgery in terms of quality of life.

Natural history of pelvic floor disorders before and after hysterectomy for gynaecological cancer

OBJECTIVE

To investigate the prevalence and severity of pelvic floor disorders (PFD), and the associations between treatment type and PFD, and cancer stage and PFD in patients before and after hysterectomy for gynaecological cancer; and the changes in outcomes over time.

DESIGN

Longitudinal cohort study.

SETTING

Gynaecological oncology outpatient clinics.

POPULATION

Patients undergoing hysterectomy for endometrial, uterine, ovarian or cervical cancer.

METHODS

Participants were assessed before, and 6 weeks and 3 months after hysterectomy. Changes over time were analysed using generalised estimating equations or linear mixed models. Associations were analysed using logistic regression models and analyses of variance.

MAIN OUTCOME MEASURES

Incontinence Severity Index, Pelvic Floor Distress Inventory-short form (PFDI-20), Female Sexual Function Index.

RESULTS

Of 277 eligible patients, 126 participated. Prevalence rates of PFD were high before (urinary incontinence [UI] 66%, faecal incontinence [FI] 12%, sexual inactivity 73%) and after (UI 59%, FI 14%, sexual inactivity 58%) hysterectomy. Receiving adjuvant therapy led to moderate-to-very severe UI 3 months after surgery compared with surgery only (odds ratio 4.98, 95% CI 1.63-15.18). There was no association between treatment type and other PFD, or cancer stage and any PFD.

CONCLUSION

Prevalence of PFD was high before and after hysterectomy for gynaecological cancer. Moderate-to-very-severe UI was associated with adjuvant therapy.

Abdominal obesity as assessed by anthropometric measures associates with urinary incontinence in females: findings from the National Health and Nutrition Examination Survey 2005-2018

BACKGROUND

Urinary incontinence (UI) is significantly link to abdominal obesity. This study aimed to assess the association between anthropometric indices of abdominal obesity, including body roundness index (BRI), conicity index (CI), and waist-to-height ratio (WHtR), and UI risk in adult females.

METHODS

We analyzed data from 10, 317 adult females in the National Health and Nutrition Examination Survey (NHANES) database (2005-2018). Weighted multivariable-adjusted regression analysis was conducted to determine the odds ratio (OR) and 95% confidence intervals (CI) for the association between BRI, CI, WHtR, and UI. Stratified analyses revealed the association based on the population type. Receiver operating characteristic curve (ROC) analyses were used to assess the predictive value of UI.

RESULTS

All indices of abdominal obesity investigated were positively and independently associated with the prevalence and severity of three types of UI. After adjusting for all relevant confounding variables, a significantly positive association between BRI and the prevalence of UI were observed (OR quartile 4 vs. quartile 1: urge UI (UUI): 1.93, 95% CI 1.61-2.30; stress UI (SUI): 2.29, 95% CI 1.94-2.70; mixed UI (MUI): 2.26, 95% CI 1.82-2.82; all P < 0.0001, P for trend < 0.0001, respectively), as well as WHtR and CI, which particularly prominent for female in premenopausal. Moreover, a one-unit increment of BRI was significantly associated with an increased severity index of UUI (β: 0.06, 95% CI 0.04-0.09, P < 0.0001), SUI (β: 0.10, 95% CI 0.07-0.13, P < 0.0001) and MUI (β: 0.07, 95% CI 0.04-0.10, P < 0.0001), which this trend was also observed in each subtype of UI for WHtR and CI. Furthermore, the ROC analysis demonstrated a higher diagnostic efficacy of BRI and WHtR compared with BMI in discriminating UI with an AUC of 0.600 for SUI, 0.617 for UUI, and 0.622 for MUI (all P < 0.05).

CONCLUSIONS

An increased BRI, CI, and WHtR are significantly associated with higher prevalence and severity of UI in females.

Mental health and lower urinary tract symptoms: Results from the NHANES and Mendelian randomization study

BACKGROUND

The clinical observations suggest a correlation between lower urinary tract symptoms (LUTSs) and mental health problems. Nonetheless, establishing a direct causal relationship between them remains challenging.

METHODS

We initially conducted a cross-sectional study using 2005-2018 the National Health and Nutrition Examination Survey (NHANES) data. Multivariable-adjusted logistic regression was the primary statistical approach. Additionally, we employed Mendelian randomization (MR) to reducing confounding and reverse causation. Genetic instruments were obtained from publicly available genome-wide association study (GWAS) databases. Inverse Variance Weighted was the primary statistical method.

RESULTS

The cross-sectional study involved 29,439 participants. Individuals with mental health problems had a higher risk of urinary incontinence (OR:4.38; 95%CI:3.32-5.76; P < 0.01) and overactive bladder (OR:2.31; 95%CI:2.02-2.63; P < 0.01). MR analysis then indicated a potential causal relationship between mental health problems and LUTSs. Depression symptoms was linked with urinary tract infection (UTI) (OR:1.005; 95%CI:1.003-1.008; PFDR < 0.01). Anxiety symptoms was related to the occurrence of UTI (OR:1.024; 95%CI:1.011-1.037; PFDR < 0.01) and bladder calcified/ contracted/ overactive (OR:1.017; 95%CI:1.007-1.027; PFDR < 0.01). The personality trait of neuroticism was related to the occurrence of cystitis (OR:1.072; 95%CI:1.022-1.125; PFDR = 0.02), extravasation of urine and difficulties with micturition (OR:1.001; 95%CI:1.001-1.002; PFDR < 0.01), and urinary frequency and incontinence (OR: 1.001; 95%CI:1.000-1.001; PFDR < 0.01).

CONCLUSIONS

Our study provides various evidence for the correlation between mental health and LUTSs, emphasizing the significance of adopting a holistic approach to LUTSs management that incorporates both physical and psychological factors.

Safety and Efficacy Report for the Use of Poly-4-Hydroxybutyrate as a Retropubic Mid-Urethral Sling (MUS) for Stress Urinary Incontinence: A Prospective 24 Months Follow-Up of New Poly-4-Hydroxybutyrate TephaFlex SUI Bioresorbable MUS

STUDY OBJECTIVE

To investigate the feasibility and safety of the retropubic mid-urethral sling (MUS) procedure with a resorbable mesh implant made of poly-4-hydroxybutyrate (P4HB).

DESIGN

A prospective clinical cohort study with 24 months follow-up.

SETTING

A tertiary academic hospital.

PATIENTS

Seventeen women with moderate to severe stress urinary incontinence (SUI).

INTERVENTIONS

A retropubic MUS procedure with P4HB sling.

MEASUREMENTS AND MAIN RESULTS

Seventeen women underwent an uncomplicated MUS procedure with a new sling made of resorbable P4HB. Following safety criteria, there has been no need to stop the study before 24 months' end point. Three serious adverse events were reported during follow-up: (1) inability to void urine after 1 week postsurgery, (2) a hysterectomy and bilateral oophorectomy performed due to a precancerous endometrial lesion at 16 months after initial MUS procedure and (3) exposed mesh with a part of device sheath left behind. These participants underwent an uncomplicated reintervention with no additional and/or permanent harm. Reinterventions because of failure of cure contained 3 second MUS procedures and one admission of urethral bulking agent. Seventy-six percent and 47 percent of patients were objectively cured of SUI at 12 and 24 months, respectively.

CONCLUSIONS

Preliminary evidence suggests that a sling made of P4HB can be safely used for MUS procedures and could be an alternative for permanent polypropylene slings in patients that prefer the use of nonpermanent material.

Reducing Falls in Older Women with Urinary Incontinence

Urinary incontinence is common in older women and doubles the risk of falls in this population. The association between urinary incontinence, especially urgency urinary incontinence, and falls is multifactorial and likely the result of a complex interaction between physical, mental, social, and environmental factors. As a result of this multifactorial etiology and based on existing evidence, the integration of different fall prevention strategies including strength and resistance exercises, bladder training, and home hazard reduction have the potential to decrease the risk of falls in older women with urinary incontinence. Given the prevalence of urinary incontinence and the significant morbidity associated with falls, effective interventions to reduce fall risk in older women with urinary incontinence is of high public health significance.

Occupational groups and lower urinary tract symptoms: A cross-sectional analysis of women in the Boston Area Community Health Study

OBJECTIVES

The objective of this study is to inform our hypothesis that the workplace toileting environment may impact lower urinary tract symptoms (LUTS); we examined the prevalence of LUTS across occupational groups in the Boston Area Community Health Survey.

METHODS

At baseline, women (n = 3205) reported their occupation and frequency of 15 LUTS. Using the US Department of Labor's Standard Occupational Classification (SOC) system, we categorized women into 11 standard occupational groups. Prevalence ratios (PRs) were calculated by log-link generalized linear models, adjusting for age, race, education, fluid intake, and parity. Women classified in Office and Administrative Support were used as the reference group given their potential for fewer workplace toileting restrictions.

RESULTS

Of the 3189 women with complete data, 68% of women reported any LUTS, ranging from 57% to 82% across the SOCs. Relative to women in Office and Administrative Support (n = 576), women in Computing, Engineering, and Science (n = 64) were more likely to report any LUTS (PR = 1.2, 95% confidence interval [95% CI]: 1.0-1.4) and urinating again in <2 h (PR = 1.7, 95% CI: 1.4-2.2), and women in Education, Legal, Community Service, Arts, and Media (n = 477), as well as Healthcare Practitioner and Technical Occupations (n = 162), were less likely to report perceived frequent daytime urination (PR = 0.6, 95% CI: 0.5-0.9 and PR = 0.6, 95% CI: 0.4-0.9, respectively).

CONCLUSIONS

Our cross-sectional findings suggest that urination frequency varies across understudied occupational groups with various workplace toileting environments. Future studies should examine this relationship prospectively to inform the influence of workplace toileting environments on urination frequency, as well as the development and/or worsening of LUTS.

Job strain, occupation, and bladder health among women

OBJECTIVES

Lower urinary tract symptoms (LUTS) are common among employed women. An underexplored topic is whether characteristics of women's occupations may influence LUTS. The present study examined whether job strain and its individual components (psychological demands, decision latitude) were associated with greater LUTS and their impact and whether, compared to managerial and professional occupations, occupations characterized by manual labor, sales, service, nursing, and teaching were associated with greater LUTS and their impact.

METHODS

Coronary Artery Risk Development in Young Adults cohort study data were analyzed. Job strain and occupation were assessed in 1987-88 and 1995-96. In 2012-13, LUTS and their impact were assessed. LUTS/impact category (a composite variable ranging from bladder health to mild, moderate, and severe LUTS/impact) was regressed on job strain and occupation in separate analyses, adjusting for age, race, parity, education, and financial hardship (n = 1006).

RESULTS

Job strain and its individual components were not associated with LUTS/impact. In comparison to managerial and professional occupations, service occupations in 1987-88 and 1995-96 were both associated with greater odds of LUTS/impact in proportional odds logistic regression analyses. Employment as a nurse, health assistant, or health aide in 1995-96 was associated with greater odds of any LUTS/impact versus bladder health. Support positions in 1987-88 and sales positions in 1995-96 were associated with greater odds of moderate or severe LUTS/impact versus bladder health or mild LUTS/impact.

CONCLUSIONS

Future research should examine characteristics of workplaces that may promote or constrain bladder health (e.g., time and autonomy to void when desired, infrastructure to void).

Financial strain across 25 years and women's bladder health: a life course perspective

BACKGROUND

A small number of cross-sectional studies have found that financial insecurity-a social determinant of health-is associated with lower urinary tract symptoms.

OBJECTIVE

This study aimed to examine (1) whether women in the Coronary Artery Risk Development in Young Adult Study with higher levels of financial strain, assessed at 7 time points across 25 years beginning in 1985-1986, were more likely to report lower urinary tract symptoms and impact after the 2010-2011 financial strain assessment and (2) whether healthcare access and comorbidities mediated potential associations.

STUDY DESIGN

This prospective cohort study recruited Black and White participants aged 18 to 30 years at baseline (1985-1986) from the populations of 4 US cities. The analytical sample was composed of women with complete data for analyses involving financial strain trajectories across 7 assessments (n=841) and mediation tests of data collected at 4 assessments (n=886). The outcome variable was previously developed through a cluster analysis of urinary incontinence severity, urinary incontinence impact, other lower urinary tract symptoms severity, and their impact in 2012-2013, which yielded 4 lower urinary tract symptoms and impact cluster categories: women with no symptom or very mild symptoms and no impact vs women with mild, moderate, or severe symptoms and impact. Financial strain was defined as finding it "very hard," "hard," or "somewhat hard" (vs "not very hard") to pay for the very basics, such as food, heating, and medical care. Using proportional odds logistic regression, cluster categories were regressed on the financial strain trajectory group, adjusting for age, race, education, and parity. For mediation analyses, separate financial strain variables (difficulty paying for the very basics, such as food and heating, and difficulty paying for medical care) were created by combining 1995-1996 and 2000-2001 values. Two healthcare access variables (difficulty receiving care and underutilization of care) and a single comorbidity index (smoking, physical inactivity, body mass index, hypertension, diabetes mellitus, and depressive symptoms) were created by combining 2005-2006 and 2010-2011 values. Regression analyses and structural equation modeling were used to test whether healthcare access and comorbidities mediated associations between financial strain and lower urinary tract symptoms and impact cluster categories.

RESULTS

In comparison to women who were consistently not financially strained, women who were consistently strained (odds ratio, 2.10; 95% confidence interval, 1.13-3.91), shifted into being strained (odds ratio, 2.00; 95% confidence interval, 1.29-3.10), or experienced >1 shift in strain (odds ratio, 1.99; 95% confidence interval, 1.46-2.71) had roughly twice the odds of reporting greater lower urinary tract symptoms and impact. Underutilization of healthcare and comorbidities mediated the association between difficulty paying for medical care and lower urinary tract symptoms and impact. In the structural equation model, difficulty paying for medical care and underutilization of care were associated (β=.31; P<.01), as was underutilization of care and greater lower urinary tract symptoms and impact (β=.09; P<.01). Moreover, difficulty paying for medical care and the comorbidity index were associated (β=.34; P<.01), as was the comorbidity index and greater lower urinary tract symptoms and impact (β=.24; P<.01). Collectively, these mediation pathways eliminated a direct association between difficulty paying for medical care and lower urinary tract symptoms and impact.

CONCLUSION

Underutilization of healthcare and comorbidities explained an association between financial strain (difficulty paying for medical care) and lower urinary tract symptoms and impact. Research is needed to confirm the findings and examine other mechanisms that may further explain the association. Accumulated evidence may inform future policies and practices.

Discrimination and bladder health among women in the CARDIA cohort study: Life course and intersectionality perspectives

OBJECTIVE

This study examines whether discriminatory experiences are associated with lower urinary tract symptoms (LUTS) and their impact among 972 women in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, which recruited participants from 4 cities in the United States.

METHOD

Exposure to discrimination was assessed 3 times (1992-93, 2000-01, 2010-11) and averaged across assessments. Participants separately reported whether they experienced discrimination on the basis of their gender, race or color, and socioeconomic position or social class. For each social identity, discrimination was assessed in 6-7 settings (e.g., when getting a job, medical care, or housing). At different time points, women who reported discriminatory experiences for a given social identity were asked how frequently the discrimination occurred and how stressful experience(s) were. Following the 2010-11 assessment, data on LUTS and their impact were collected. Women were classified into bladder health versus mild, moderate, or severe symptoms/impact clusters.

RESULTS

More Black than White women reported discriminatory experiences across all social identities and most settings. Perceived stress of discriminatory experiences did not differ between Black and White women. In analyses stratified by race and social identity, White women reported LUTS/impact with discriminatory experiences in more settings, more frequent discriminatory experiences across settings, and each additional social identity for which discrimination was experienced. Black women reported LUTS/impact with more frequent discriminatory experiences across settings. For Black women, greater perceived stress of both gender and race discrimination were associated with LUTS/impact. For White women, only greater perceived stress of race discrimination was associated with LUTS/impact.

CONCLUSIONS

This is one of the first studies to examine discrimination in relation to LUTS/impact. Additional research is needed to better understand differences in how discriminatory experiences based on potentially intersecting identities may be related to bladder health among women.

The Role of the Supine Empty Stress Test in the Evaluation of Women with Stress Urinary Incontinence: A Retrospective Cohort Study

The International Continence Society recommends the supine empty stress test (SEST) as an accessory test in the evaluation of women with urinary incontinence, especially for the presence of intrinsic sphincter deficiency (ISD). The aim of this study was to investigate the relationship between the SEST and clinical findings in women diagnosed with stress urinary incontinence with single voiding cycle ambulatory urodynamics (AUM). AUM tracings of patients with lower urinary tract symptoms (LUTS = Lower urinary tract symptoms) (n = 513) were retrospectively reviewed, and 364 charts with urodynamic SUI were analyzed. Demographics, examination findings, scores of the Sandvik Incontinence Severity Index and validated questionnaires, and AUM findings were compared between SEST-positive and -negative groups. Additionally, the diagnostic accuracy of the SEST in the diagnosis of low abdominal leak point pressure (ALPP ≤ 60 cm H2O) in women with pure urodynamic SUI was calculated. The SEST was positive in 41.8% (n = 152) of the cohort. Women with a positive SEST had higher scores on the Sandvik severity index (9.2 ± 3.6 vs. 7.5 ± 3.8, p = 0.003) and lower ALPP (79.6 ± 29.3 vs. 98.4 ± 31.3, p < 0.001). The negative predictive value of the SEST for ISD was found to be 92.4%. Thus, the SEST seems to be an objective clinical test reflecting urinary incontinence severity while excluding the presence of ISD.

Association of Pelvic Floor Disorders, Perceived Psychological Stress, and Military Service in U.S. Navy Servicewomen: A Cross-Sectional Survey

IMPORTANCE

Pelvic floor disorders (PFDs) are linked to psychological stress and decreased work performance in civilian populations. Higher psychological stress is reported in female active-duty servicewomen (ADSW), which affects military readiness.

OBJECTIVE

This study sought to associate PFDs, work-related challenges, and psychological stress in ADSW.

STUDY DESIGN

We conducted a single-site, cross-sectional survey of ADSW seeking care in the urogynecology, family medicine, and women's health clinics between December 2018 and February 2020 using validated questionnaires to determine the prevalence of PFDs and the association with psychological stress, performance of military duties, and continued military service.

RESULTS

One hundred seventy-eight U.S. Navy ADSW responded; most were seeking care for PFDs. The reported prevalence rates of PFDs were as follows: urinary incontinence, 53.7%; pelvic organ prolapse, 16.3%; fecal incontinence, 73.2%; and interstitial cystitis/bladder pain syndrome, 20.3%. Active-duty servicewomen with PFDs were more likely to have higher psychological stress scores (22.5 ± 3.7 vs 20.5 ± 4.2, P = 0.002) and body composition failures (22.0% vs 7.3%, P = 0.012), yet more strongly consider remaining on active service if they reported urinary incontinence (22.8% vs 1.8%) or interstitial cystitis/bladder pain syndrome (19.5% vs 1.8%; all P ≤ 0.001). No significant differences were noted in physical fitness failures or other military duties.

CONCLUSIONS

For these U.S. Navy ADSW with PFDs, there was no significant difference in duty performance but reported psychological stress levels were higher. The presence of PFD was associated with women more strongly considering ongoing military service compared with other factors such as family, job, or career path.

Clinical and laboratory results in vaginal wall restoration using a fractional-pixel-CO2 laser: histological findings and changes in the Ki67 protein and telomere length

Thermal deposition of laser energy in the vaginal epithelium in genitourinary syndrome of menopause (GSM) results in clinical and biological effects, but many cellular and molecular changes indicating cell proliferation or senescence inhibition are unknown. The aim of this study is to evaluate the clinical efficacy of the fractional-pixel-CO2 laser in the possible improvement of GMS signs and symptoms that can be correlated with histological changes or with cellular or molecular indicators of restoration. A detailed prospective study was designed to assess 17 women diagnosed with GSM who were treated intravaginally with two laser sessions. Seven non-treated women diagnosed with GSM were used as controls. Three validated outcome questionnaires for assessment of quality of sexual life and urinary incontinence were performed. Vaginal biopsies were collected before the first laser treatment and 4 months following the second session. Histological status, elastin, collagen, and hyaluronic acid content of the biopsies were also evaluated. Cell proliferation was assessed by Ki67 staining. Telomere length (TL) was measured by qPCR. The results show an improvement of the clinical symptoms of GSM (p < 0.05), vaginal epithelium recovery and enhancement of collagen (p < 0.05), elastic fibers (p < 0.005), and hyaluronic acid (p < 0.0005) content in the lamina propria after fractional-pixel-CO2 laser treatment. The laser treatment induced a significant rise on the TL of vaginal epithelial cells (VECs), and a positive correlation was found between the improvements of the collagen and hyaluronic acid content and TL changes (r = 0.82, p < 0.05; r = 0.38, p < 0.05). The percentage of proliferative Ki67-positive VECs was increased in patients whose vaginal TL lengthened after laser treatment (p < 0.05). In conclusion, the results indicate that laser treatment may induce restoration of the vaginal epithelium which is associated to increased TL and proliferation in the VECs. Performing a TL assay could be a suitable tool to evaluate the efficacy of vaginal laser treatment.

The impact of postinjection urinary tract infection on efficacy of intravesical onabotulinumtoxinA-A secondary analysis

OBJECTIVES

To compare treatment response in women who did and did not develop a urinary tract infection (UTI) within 14 days after intravesical onabotulinumtoxinA injections for treatment of refractory urgency urinary incontinence (UUI).

METHODS

This is a secondary analysis of women who received Onabotulinumtoxin A in the Refractory Overactive Bladder: Sacral Neuromodulation vs Botulinum Toxin Assessment (ROSETTA) Trial. Participants were grouped by presence or absence of UTI within 14 days of injection. UTI was defined as symptomatic with positive urine culture per the primary ROSETTA protocol. Our primary outcome was change from baseline in mean number of UUI episodes based on monthly 3-day bladder diaries averaged over 6 months. We performed t tests and chi-square/Fisher's exact for continuous and categorical variables. A p value of <0.05 was considered statistically significant.

RESULTS

Of 187 participants in the onabotulinumtoxinA arm, 10 (5.3%) experienced UTI within 14 days of injection, and 177 (94.7%) did not. At baseline, groups did not differ in demographics, mean UUI episodes per day (no UTI [5.37 ± 2.65] vs. UTI [6.40 ± 3.02], p = 0.24), or other diary parameters. For our primary outcome, groups did not differ in the change in mean daily UUI episodes at 1 month (no UTI [-4.29 ± 2.75] vs. UTI [-3.74 ± 2.01]; mean difference [95% confidence interval, CI] -0.55 [-2.39 to 1.28], p: 0.55) or 6 months (no UTI [-3.63 ± 2.89] vs. UTI [-2.15 ± 3.18]; mean difference [95% CI] -1.48 [-3.44 to 0.48], p: 0.14).

CONCLUSIONS

UTI within 14 days after intravesical injection of onabotulinumtoxinA for refractory UUI was not significantly associated with inferior treatment response at 1 or 6 months.

Treatment for Urinary Incontinence in Women Older Than 65 Years

IMPORTANCE

Urinary incontinence (UI) is common among women older than 65 years and negatively affects quality of life. However, the prevalence of UI treatment and determinants of treatment are largely unknown.

OBJECTIVES

The aim of this study was to identify rates of UI treatment and factors associated with treatment in older women with self-reported UI.

STUDY DESIGN

This is a retrospective cohort analysis of a data set linking UI symptoms from the Nurses' Health Study to Medicare claims. We evaluated use of pharmacotherapy, noninvasive, and procedural treatments for UI within 1 year before symptom survey. For pharmacotherapy, we used multivariable logistic regression to estimate odds ratios (ORs) of UI treatment.

RESULTS

Of the 67,587 Nurses' Health Study respondents, 15,088 had linkage to Medicare, subscribed to part D, and answered UI questions. Of these, 8,332 (55.2%) women reported UI, and 10.9% with UI had a Medicare claim for treatment; pharmacotherapy represented 94.6% of all treatments.On regression analysis, women with more severe and longer-term UI had higher odds of treatment (severe vs slight UI: OR, 3.1; 95% confidence interval [CI], 2.2-4.3) (longer vs new UI: OR, 1.9; 95% CI, 1.5-2.3). Women with mixed (OR, 2.5; 95% CI, 1.9-3.2) or urgency UI (OR, 3.0; 95% CI, 2.2-3.9) had greater odds of treatment compared with women with stress UI.

CONCLUSIONS

We estimate that only approximately 1 in 9 older women with self-reported UI underwent treatment within the year before reporting symptoms, of which pharmacotherapy was the most common UI intervention, and women with more severe and longer duration of symptoms were most often treated.

Trajectories of depressive symptoms over 20 years and subsequent lower urinary tract symptoms and impact among women

OBJECTIVE

The aim of the study is to examine the association between depressive symptoms and subsequent lower urinary tract symptoms (LUTS) and impact (a composite outcome) among women (N = 1,119) from the Coronary Artery Risk Development in Young Adults study.

METHODS

The Center for Epidemiologic Studies-Depression Scale (CES-D) was administered in 1990-1991 and every 5 years through 2010-2011. In 2012-2013, LUTS and impact data were collected for the first time. Accumulation of risk was examined in the following three ways: (1) mean CES-D score across 20 years (5 observations); (2) depressive symptom trajectory group, determined by group-based trajectory modeling; and (3) intercepts and slopes obtained from women's individual CES-D score trajectories through two-stage mixed effects modeling. For each approach, ordinal logistic regression analyses examined odds of having "greater LUTS/impact" for each unit change in a depressive symptom variable.

RESULTS

(1) With each one-unit increase in mean CES-D score over the 20-year period, women were 9% more likely to report greater LUTS/impact (odds ratio [OR] = 1.09, 95% CI = 1.07-1.11). (2) In comparison with women with consistently low depressive symptoms, women with consistently threshold depression or consistently high depressive symptoms were twice (OR = 2.07, 95% CI = 1.59-2.69) and over five times (OR = 5.55, 95% CI = 3.07-10.06) as likely, respectively, to report greater LUTS/impact. (3) Women's individual symptom intercept and slope interacted. Increases in depressive symptoms across 20 years (greater slopes) were associated with greater LUTS/impact when women's initial CES-D score (intercept) was in the moderate-to-high range relative to the sample.

CONCLUSIONS

Depressive symptoms over 20 years, examined with different degrees of nuance, were consistently associated with subsequently measured LUTS and impact.

Interpersonal Stressors and Resources for Support: Associations with Lower Urinary Tract Symptoms and Impact Among Women

Background: This study utilizes Coronary Artery Risk Development in Young Adults (CARDIA) data to examine whether women's perceived emotional support and interpersonal stressors are associated with lower urinary tract symptoms (LUTS) and their impact on quality of life. Materials and Methods: Emotional support was assessed at baseline/year 0 (1985-86), year 2 (1987-88), year 15 (2000-01), and year 20 (2005-06); interpersonal stressors were assessed at years 15 and 20. In 2012-13, LUTS and impact were assessed. LUTS/impact category (a composite variable ranging from bladder health to mild, moderate, and severe LUTS/impact) was regressed on trajectory groups of emotional support from years 0 to 20. Separately, LUTS/impact was regressed on mean emotional support and interpersonal stressors across years 15-20. Analyses were adjusted for age, race, education, and parity (n = 1104). Results: In comparison to women whose support trajectory from years 0 to 20 was consistently high, women whose support decreased from high to low had over twice the odds (odds ratio [OR] = 2.72; 95% confidence interval [CI] = 1.76-4.20) of being classified into a more burdensome LUTS/impact category. Mean support and interpersonal stressors across years 15-20 were independently associated with lower odds (OR = 0.59; 95% CI = 0.44-0.77) and greater odds (OR = 1.52; 95% CI = 1.19-1.94), respectively, of being classified into a more burdensome LUTS/impact category. Conclusions: In the CARDIA cohort, quality of women's interpersonal relationships, assessed between 1985-86 and 2005-06, was associated with LUTS/impact assessed in 2012-13. Additional research collecting LUTS/impact data at multiple time points is needed to test potential bidirectional associations of emotional support and interpersonal stressors with LUTS/impact, as well as potential mechanisms of association.

Association of urinary incontinence with depression among men: a cross-sectional study

OBJECTIVE

Depression and urinary incontinence (UI) are both troubling symptoms that severely impact quality of life. The aim of this study is to evaluate the association between UI (including UI types and severity) and depression among men.

POPULATION AND METHODS

The analyzed data was collected from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) data. A total of 16,694 male participants aged ≥ 20 years with complete information about depression and UI were included in this study. Logistic regression was performed to calculate the odds ratio (OR) and 95% confidence interval (CI) to determine the association between depression and UI by adjusting for relevant covariables.

RESULTS

The prevalence of depression was 10.91% among participants with UI. Urge UI was the main type of UI and accounts for 50.53% of all UI types. The adjusted ORs for the association between depression and UI were 2.69 (95%CI, 2.20-3.28). Compared with slight UI, the adjusted ORs were 2.28 (95% CI, 1.61-3.23) for moderate UI, 2.98 (95% CI, 1.54-5.74) for severe UI, and 3.85 (95% CI, 1.83-8.12) for very severe UI. Compared with no UI, the adjusted ORs were 4.46 (95% CI, 3.16-6.29) for mixed UI, 3.15 (95% CI, 2.06-4.82) for stress UI, and 2.43 (95% CI, 1.89-3.12) for urge UI. The subgroup analyses also showed similar correlation about depression and UI.

CONCLUSION

Among men, depression was positively associated with UI status, severity and types. For clinicians, it's necessary to screen depression in patients with UI.

Influence of prenatal urinary incontinence and mode of delivery in postnatal urinary incontinence: A systematic review and meta-analysis

BACKGROUND

It is likely that the pathophysiology of urinary incontinence (UI) differs between women who are incontinent before the first delivery and those whose incontinence occurs after. In this systematic review, we aimed to assess the association between the mode of delivery and the risk of postpartum UI in primiparous women with and without prenatal UI.

METHODS

We searched MEDLINE, Cochrane, Web of Science, Embase and CINHAL databases. Prospective studies including primiparous women during their pregnancy with a comparison of the rate of postpartum UI in women who underwent cesarean delivery or vaginal delivery according to continence status before delivery were included. The Risk Ratio (RR) was calculated with a 95% confidence interval (95% CI) using the total number of events and patients extracted from the individual studies. A subgroup comparison analysed the potential influence of women's prenatal continence status. Heterogeneity was estimated using I² statistics.

RESULTS

The risk of postpartum UI was significantly higher after vaginal delivery than after cesarean section (RR 1.80, 95% CI 1.48- 2.18). According to the subgroup test, the postpartum UI risk following a vaginal delivery, compared to cesarean section, was significantly higher in the subgroup of continent women during pregnancy (RR 2.57, 95% CI 2.17-3.04) than in the subgroup of incontinent pregnant women (1.56, 95% CI 1.27-1.92).

CONCLUSIONS

The effect of a cesarean section in preventing postpartum UI appears controversial, particularly in women with prenatal UI.

Effect of monopolar capacitive resistive radiofrequency in treating stress urinary incontinence: A pilot randomized control trial

Objective

To assess the effectiveness of 448 kHz monopolar capacitive resistive radiofrequency (MCRR) in the treatment of females with stress urinary incontinence (SUI).

Materials and methods

Forty females with SUI complaints were separated randomly into two equal groups. Group A with 20 females received the MCRR therapy for 20 min and performed pelvic floor exercises for 20 min. Group B with 20 females received placebo treatment by applying the same application as in Group A without emitting any waves for 20 min, three times a week, for 4 weeks. The patients in both groups were instructed to pause the treatment during their menstruation; the patients were instructed to maintain home pelvic floor exercises. Both groups were assessed by a perineometer that was used to assess the strength of the pelvic floor muscles (PFM), the visual analogue scale (VAS), and the Incontinence Symptom Severity Index to assess the frequency of urinary incontinence symptoms as described by each patient before treatment and after 4 weeks of treatment.

Results

There was a significant reduction (p < 0.05) in VAS and the Incontinence Symptom Severity Index and a significant increase in the strength of the PFM in both groups post-treatment compared with the pre-treatment. Regarding between-subject effects, there was a significant difference in VAS, the Incontinence Symptom Severity Index, and the perineometer between both groups (p < 0.05), and this significant improvement favored Group A.

Conclusion

MCRR and pelvic floor exercises are more effective methods for the treatment of SUI than just pelvic floor exercises of females with SUI.

Impact of a Community-Based Pelvic Floor Kinesic Rehabilitation Program on the Quality of Life of Chilean Adult Women with Urinary Incontinence

The pelvic floor forms the primary bottom tissue of the pelvic cavity. It comprises muscles that play a fundamental role in bowel and bladder emptying. Alterations of pelvic floor muscles will result in dysfunctions such as urinary incontinence (UI). Given the high prevalence of UI and its impact on the quality of life (QoL) in patients with pelvic floor muscle dysfunctions, it is necessary to implement public, community, and generalized programs focused on treating these dysfunctions.

OBJECTIVE

To determine the effect of a community rehabilitation program on QoL, UI severity, and pelvic floor muscle strength in patients with UI.

PATIENTS AND METHOD

A descriptive prospective cohort study. Twenty subjects between 44 and 75 years old with a diagnosis of UI, participants of a community kinesic rehabilitation program on the pelvic floor in Maipú, Santiago, Chile, were evaluated. These volunteers were intervened for six months, and QoL was measured with the 36-Item Short-Form Health Survey (SF-36) and International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) scales, UI severity with the Sandvick test, and pelvic floor muscle strength with the Oxford scale. Patients were followed up three months post-intervention.

RESULTS

Significant improvements were observed in all scales after applying for the community kinesic rehabilitation program, and the changes were maintained at a 3-month follow-up.

CONCLUSIONS

Since the improvement in QoL, UI severity, and pelvic floor muscle strength after the intervention, it is relevant to consider the implementation of community programs aimed at education, screening, and early rehabilitation of these patients.

Micturition symptoms in gynecologic cancer patients receiving paclitaxel and platinum-based chemotherapy regimen: a prospective study

OBJECTIVE

To evaluate the effect of paclitaxel and platinum-based chemotherapy (PT) on micturition symptoms.

METHODS

All gynecologic cancer patients who were assigned to receive the PT regimen and understood the Thai language were invited to participate in this study. The exclusion criteria were as follows: abnormal urinary symptoms, retained urinary catheter or percutaneous nephrostomy, anticholinergic drug use, or scheduled to receive radiation therapy after the completion of chemotherapy. The participants were interviewed using three Thai validated questionnaires, the incontinence impact questionnaire-short form, urogenital distress inventory short form, and Sandvik score, on the day before receiving the first cycle of chemotherapy (pre-treatment), on the day before receiving the 4th cycle (mid-treatment), and 46 weeks after completing 69 cycles (post-treatment). The scores at the three time points were compared. Patients who received less than three cycles were not included in the analysis.

RESULTS

One hundred and ten patients were included in this study. There were significant differences in the median questionnaire scores at the three time points for both carboplatin plus paclitaxel and cisplatin plus paclitaxel. However, when using a pairwise difference between the two treatment protocols, there were no significant changes in the score from pre-treatment to post-treatment.

CONCLUSION

The PT regimen has an impact on micturition symptoms during chemotherapy which recover after treatment completion.

Attitudes and barriers to pelvic floor muscle exercises of women with stress urinary incontinence

Background

Pelvic floor muscle exercise (PFME) is a first-line treatment for stress urinary incontinence (SUI), but adherence to PFME is often problematic. The aim of this study was to better understand the attitudes and barriers to practicing pelvic floor muscle exercise among women with SUI.

Methods

We conducted a qualitative study using semi-structured interviews. Purposive sampling was used to approach eligible participants. The interview included questions focused on women’s perceptions regarding SUI and PFME, sources of information, support, and barriers and motivators of PFME. In-depth interviews were conducted until data saturation occurred. After several readings of written interview transcripts, codes were retrieved, and thematic analysis was conducted.

Results

Seven women participated in the study (average age 53.2 years), and most (4/7) were retired. Three salient themes emerged from the data: (1) perception of SUI, (2) barriers to PFME, and (3) motivators to exercise. Participants highlighted various barriers to PFME: (1) lack of self-discipline owing to both intrinsic and extrinsic factors, (2) lack of confidence in how to perform the exercises properly, and (3) skepticism regarding the efficacy of treatment according to women’s direct and indirect experiences. Achievement of desired outcomes, symptom severity, women’s expectations, and fear of surgery were motivators to regularly perform PFME.

Conclusions

The main barriers to regular PFME were inadequate self-discipline, knowledge, and confidence in performing the exercises, and a poor perception about the effectiveness of PFME.

Urinary Incontinence and Sleep Quality in Older Women with Type 2 Diabetes: A Cross-Sectional Study

BACKGROUND

Urinary incontinence (UI) and poor sleep negatively affect health-related quality of life (HRQoL). This study explored the UI-related factors and the relationships between UI, sleep quality, and HRQoL.

METHODS

This cross-sectional study collected data from 237 women with type 2 diabetes. Multivariate logistic regression was conducted to identify the factors associated with UI. One-way analysis of variance was used to compare the mean sleep quality and HRQoL scores of women without UI and those who experienced UI of varying severities. Correlation coefficients were estimated, and multivariate linear regression was conducted to examine the relationships between UI severity, sleep quality, and HRQoL.

RESULTS

Of the 237 women, 115 (48.52%) experienced UI and 139 (58.65%) were poor sleepers. The three factors associated with UI were advanced age, a higher body mass index, and a history of vaginal delivery. Significant associations between UI severity and sleep quality and between sleep quality and HRQoL were revealed. UI severity and night-time voiding frequency were both associated with sleep quality.

CONCLUSIONS

One factor associated with UI (body mass index) is modifiable. UI severity is associated with sleep quality as the possible influence of night-time voiding frequency on sleep quality has been considered.

Physicians’ perspectives on using a patient decision aid in female stress urinary incontinence

Introduction and hypothesis

A treatment choice for female stress urinary incontinence (SUI) is preference sensitive for both patients and physicians. Multiple treatment options are available, with none being superior to any other. The decision-making process can be supported by a patient decision aid (PDA). We aimed to assess physicians’ perceptions concerning the use of a PDA.

Methods

In a mixed methods study, urologists, gynecologists and general practitioners in the Netherlands were asked to fill out a web-based questionnaire. Questions were based on the Tailored Implementation for Chronic Diseases checklist using the following domains: guideline factors, individual health professional factors, professional interactions, incentives and resources, and capacity for organizational change. Participants were asked to grade statements using a five-point Likert scale and to answer open questions on facilitators of and barriers to implementation of a PDA. Outcomes of statement rating were quantitatively analyzed and thematic analysis was performed on the outcomes regarding facilitators and barriers.

Results

The response rate was 11%, with a total of 120 participants completing the questionnaire. Ninety-two of the physicians (77%) would use a PDA in female SUI. Evidence-based and unbiased content, the ability to support shared decision making, and patient empowerment are identified as main facilitators. Barriers are the expected prolonged time investment and the possible difficulty using the PDA in less health-literate patient populations.

Conclusions

The majority of physicians would use a PDA for female SUI. We identified facilitators and barriers that can be used when developing and implementing such a PDA.

Conservative interventions for treating urinary incontinence in women: an Overview of Cochrane systematic reviews

BACKGROUND

Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment.

OBJECTIVES

To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women.

METHODS

We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear.

MAIN RESULTS

We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone.

AUTHORS' CONCLUSIONS

There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.

Urination Frequency Ranges in Healthy Women

BACKGROUND

Limited information on the normal range of urination frequencies in women is available to guide bladder health promotion efforts.

OBJECTIVES

This study used data from the Boston Area Community Health (BACH) Survey to (a) estimate normative reference ranges in daytime and nighttime urination frequencies in healthy women based on two operational definitions of "healthy" and (b) compare urination frequencies by age, race/ethnicity, and fluid intake.

METHODS

A secondary analysis of cross-sectional interview data collected from female participants was performed using less restrictive ("healthy") and strict ("elite healthy") inclusion criteria. All analyses were weighted to account for the BACH sampling design. Normative reference values corresponding to the middle 95% of the distribution of daytime and nighttime urination frequencies were calculated overall and stratified by age, race/ethnicity, and fluid intake. Generalized linear regression with a log-link was used to estimate rate ratios of daytime and nighttime urination frequencies by age, race/ethnicity, and fluid intake.

RESULTS

Of the 2,534 women who completed the BACH follow-up interviews, 1,505 women met healthy eligibility criteria, and 300 met elite healthy criteria. Overall, reference ranges for urination frequencies were 2-10 times/day and 0-4 times/night in healthy women and 2-9 times/day and 0-2 times/night in elite healthy women. Women ages 45-64 years, but not 65+ years, reported a greater number of daytime urination than those aged 31-44 years, whereas women 65+ years reported a greater number of nighttime urination. Black women reported fewer daytime urination and more nighttime urinations than White women. Women who consumed less than 49 oz daily reported fewer daytime and nighttime urinations than those who drank 50-74 oz; drinking 75+ oz had only a small effect on urination frequencies.

DISCUSSION

Normative reference values for daytime and nighttime urination frequencies were similar in women using strict and relaxed definitions of health. These results indicate a wide range of "normal" urination frequencies, with some differences by age, race/ethnicity, and fluid intake. Future research is needed to examine urination frequencies in minority women and whether fluid intake amount and type influence the development of lower urinary tract symptoms.

Association between body mass index, trunk and total body fat percentage with urinary incontinence in adult US population

INTRODUCTION AND HYPOTHESIS

To assess the association of body mass index (BMI), trunk and total body fat percentage with the prevalence and severity of urinary incontinence (UI) stratified by gender among a US adult population.

METHODS

A representative cross-sectional survey of participants aged ≥ 20 years was conducted using the data from the 2011-2018 National Health and Nutrition Examination Survey. Multivariate logistic and linear regression models were used to explore the association among the three obesity measures above with the prevalence and severity of UI.

RESULTS

A total of 6964 individuals (4168 males and 2796 females) enrolled for the final analysis. Among males, the weighted prevalence of UI was 7.8%, with 1.3% stress urinary incontinence, 5.8% urge urinary incontinence and 0.7% mixed urinary incontinence. For females, the weighted prevalence of UI was 54.2%, with 31.9% stress urinary incontinence, 7.0% urge urinary incontinence and 15.6% mixed urinary incontinence. Multivariate logistic regression revealed increased BMI and trunk fat percentage significantly increased odds of UI (BMI: OR = 1.05 [per 1 kg/m²], 95% CI: 1.03-1.07, P < 0.001; trunk fat percentage: OR = 1.15 [per 5% increase in trunk fat percentage], 95% CI: 1.06-1.25, P = 0.002) in females. Similar trends were observed in the severity of UI (BMI: β = 0.07, 95% CI: 0.05-0.09, P < 0.001; trunk fat percentage: β = 0.18, 95% CI: 0.10-0.26, P < 0.001) by a multivariate linear regression. In males, no significant association was observed (BMI: OR = 0.99 [per 1 kg/m²], 95% CI: 0.97-1.02, P = 0.663; trunk fat percentage: OR = 0.95 [per 5% increase in trunk fat percentage], 95% CI: 0.84-1.08, P = 0.430; total fat percentage: OR = 0.94 [per 5% increase in total fat percentage], 95% CI: 0.80-1.10, P = 0.424).

CONCLUSIONS

An increased BMI and trunk fat percentage are significantly associated with higher prevalence and severity of UI in females.

Prevalence and severity of urinary incontinence among male and female competitors and recreational CrossFit® practitioners

OBJECTIVE

This study aimed to determine the prevalence, severity and type of urinary incontinence (UI) in female and male CrossFit® practitioners.

STUDY DESIGN

The study design is an online cross-sectional survey distributed to CrossFit® practitioners across all Spanish regions. The questionnaire included categorical questions related to CrossFit® practice, multiple-choice questions to determine the exercises performed during reported UI symptoms, and The International Consultation on Incontinence Questionnaire Short-Form questionnaire items.

RESULTS

Five hundred seventy-one practitioners (34.0 ± 8.37 years, Body Mass Index 24.20 ± 3.34 kg/m²) met inclusion criteria and completed the survey. There were and 316 females and 255 males. Around 45 % of women and 6 % of men reported having UI (p < 0.001). The severity of UI mainly was slight (30.3 % women, 3.5 % men) and moderate (11.7 % women, 2.3 % men) (p < 0.001). Stress and urgent UI were the most prevalent types among women (36 %) and men (5 %) (p < 0.001).

CONCLUSIONS

This study found that UI is relatively common among female CrossFit® practitioners, especially in repetitive jumps. The practitioners' profile (amateur/competitor) does not affect the prevalence or severity of UI. Male athletes can also experience urine leakage while performing CrossFit®, although its prevalence is much lower when compared to female practitioners.

Physical Activity Reduces the Effect of High Body Mass Index on Kidney Stones in Diabetes Participants From the 2007–2018 NHANES Cycles: A Cross-Sectional Study

Background

Body mass index (BMI) is a vital risk factor for kidney stones, but physical activity may reduce the incidence of kidney stones. However, it remains unknown whether physical activity reduces the effect of high BMI on kidney stones in diabetes participants.

Methods

We included clinical information from 4,008 adult participants with diabetes from the National Health and Nutrition Examination Survey (NHANES) database from 2007 to 2018. Univariate and multivariate logistic regression analyses were used to analyze the relationship between BMI and kidney stones, as well as the risk of BMI and kidney stones in different physical activity subgroups.

Results

A total of 4,008 diabetic participants were included in this study, of whom 652 (16.3%) self-reported a history of kidney stones. Logistic regression analysis showed a positive association between BMI and kidney stones. After adjusting for other confounders, the adjusted ORs for the risk of kidney stones was 1.514 (95% CI, 1.134–2.022, p = 0.005) for participants with BMI ≥30 kg/m² among all participants; the risk of kidney stones was elevated (OR = 1.572, 95% CI, 1.134–2.022, p = 0.005) in group without physical activity, and a reduced risk (OR = 1.421, 95% CI, 0.847–2.382, p = 0.183) in the group with physical activity. Furthermore, similar results were found in most subgroups.

Conclusion

Our study suggests that high BMI is a risk factor for diabetes kidney stone participants and that physical activity may moderate this relationship to some extent.

Sexual Function Following Treatment for Stress Urinary Incontinence With Bulk Injection Therapy and Mid-Urethral Sling Surgery

BACKGROUND

Peri-urethral bulking injections (PBI) gain popularity for the treatment of stress urinary incontinence (SUI), but - in contrast to mid-urethral sling (MUS) surgery - little is known about its impact on sexual function.

METHODS

This was a secondary analysis of a prospective cohort study that included patients with moderate to severe SUI undergoing either MUS surgery or PBI with polydimethylsiloxane Urolastic (PDMS-U). The validated Dutch and English version of the 'Pelvic Organ Prolapse and/or Urinary Incontinence Sexual Function Questionnaire - IUGA Revised' (PISQ-IR) was used to assess sexual function at baseline, at 6 and 12 months of follow-up. For between-group analysis, differences in baseline characteristics were corrected using multivariate analysis of covariance.

OUTCOMES

The primary outcome was the PISQ-IR single summary score of sexually active (SA) women following both procedures, calculated by mean calculation. Secondary outcomes were the PISQ-IR subscale scores of SA and non-sexually active (NSA) women, the proportions of sexual activity and subjective improvement ('Patient Global Impression of Improvement' (PGI-I)).

RESULTS

A total of 259 women (MUS: n = 146, PBI: n = 113) were included in this study. The PISQ-IR single summary score of SA women improved following both interventions (in the MUS group from 3.2 to 3.4 and in the PBI group from 3.0 to 3.3 after 12 months). After correcting for differences in baseline characteristics, the PISQ-IR summary score at 6 and 12 months was similar for both treatment groups. For SA women, condition-specific and condition-impact subscale scores significantly improved following both procedures.

CLINICAL IMPLICATIONS

In treating SUI, PBI is inferior to MUS surgery. However, there is a need for less invasive strategies, especially for women who are unfit for surgery or have contraindications. Sexual function improves after PBI using PDMS-U, which is relevant for the counselling of women with SUI about available treatment options.

STRENGTHS & LIMITATIONS

Strength: until this study, there was a lack of knowledge about the effects of PBI on sexual function.

LIMITATION

there may be indication bias as we did not perform a randomized controlled trial.

CONCLUSION

PBI using PMDS-U and MUS surgery for the treatment of SUI improve sexual function equally in SA women, mainly by decreasing the condition's impact on sexual activity and quality.

The neglected secret: Association of abdominal striae with stress urinary incontinence in primigravid pregnant women

OBJECTIVE(S)

To compare the presence and severity of striae gravidarum in pregnant women with and without stress urinary incontinence and to evaluate whether there is a relationship between the severity of striae gravidarum and the severity of incontinence in pregnant women with stress urinary incontinence.

STUDY DESIGN

Healthy primigravid pregnant women with an uneventful singleton pregnancy at 36-37 weeks of gestation were included. All women were asked two questions to assess the presence of urinary incontinence. Women who answered 'yes' to the question 'Do you have any involuntary urinary leakage during coughing/laughing/sneezing/running/jumping?' and 'no' to the question 'Do you have any involuntary urinary leakage accompanied by a strong urge to void?' were classified as women with stress urinary incontinence, and women who answered 'no' to both questions were classified as women without stress urinary incontinence. The presence and severity of striae gravidarum of these two groups were evaluated with the Davey score, and the severity of incontinence of women with stress urinary incontinence was evaluated with the Incontinence severity index questionnaire.

RESULTS

The Davey score of pregnant women with stress urinary incontinence was significantly higher than the score of women without stress urinary incontinence and the presence of severe striae gravidarum was more common in women with stress urinary incontinence. There was a positive, significant correlation between Incontinence severity index and Davey scores in women with stress urinary incontinence, and this was the only independent correlation that was significant in linear regression analysis.

CONCLUSION(S)

Presence and severity of striae gravidarum is correlated with the presence and severity of stress urinary incontinence in primigravid pregnant women. Evaluation of striae gravidarum may be useful in predicting the development of stress urinary incontinence and taking necessary precautions against it. This issue should be evaluated with good quality studies.

The relative importance of different consequences of nocturnal enuresis among older women: A conjoint analysis experiment

INTRODUCTION

Adult nocturnal enuresis (NE) is an understudied and bothersome condition. Our objective was to conduct a conjoint analysis experiment to better understand the relative importance of NE consequences in older women.

METHODS

We developed a conjoint analysis survey that included four attributes related to NE (awakening at night, feeling rested in the morning, restricting fluid before bed, and wet perineal skin). We performed a prospective cross-sectional online study of women >62 years of age with NE using Sawtooth Software. Patients completed baseline questions, the International Consultation on Incontinence Questionnaire-nocturia Quality of Life (ICIQ-NqoL), and the conjoint analysis experiment. Hierarchical Bayes random effects regression analysis was used to determine the relative importance of the four attributes.

RESULTS

A total of 200 women with a mean age of 71 years completed the study. The most common management of NE was diapers/pads (132/200). Approximately half of the participants experienced NE several times a week or nightly (101/200). The most important attribute was the frequency of being awakened at night (34, standard deviation [SD]: 16) and the frequency of feeling rested in the morning (32, SD: 15). Limiting drinking before bed (18, SD: 12) and wet groin skin (16, SD: 10) had significantly lower importance scores (p < 0.05). Age, sleeping with a partner in bed, body mass index, NE severity score, and the ICIQ-NqOL score were not significantly associated with any of the importance scores.

CONCLUSIONS

Older women with NE place significantly more importance on the frequency of awakening at night, and feeling rested in the morning and lesser importance on associated lifestyle or physical manifestations of NE.

Comparing the efficacy of the Knack maneuver on pelvic floor muscle function and urinary symptoms using different teaching methods: a prospective, nonrandomized study

INTRODUCTION AND HYPOTHESIS

This study was aimed at comparing the efficacy of Knack maneuver training taught using different techniques on pelvic floor muscle (PFM) function, urinary symptoms, and perception of improvement in women with stress urinary incontinence (SUI).

METHODS

We conducted a prospective nonrandomized study of 46 women with SUI. Assessments included: PFM functions (secondary outcome, SO) using a Myomed 932 EMG biofeedback device, urinary incontinence symptoms using the International Consultation on Incontinence Questionnaire Urinary Incontinence-Short Form (ICIQ-SF; primary outcome), the Urogenital Distress Inventory-6 (UDI-6; SO), and the Incontinence Severity Index (ISI; SO), and perception of improvement using the Global Perceived Impact scale. The women were divided into three groups according to their preference: group 1 (Knack maneuver training with electromyography biofeedback), group 2 (Knack maneuver training with verbal instruction), and group 3 (Knack maneuver training with vaginal palpation). An education program was also given to all women individually. The training program was 1 day per week for 4 weeks.

RESULTS

There was an improvement in UDI-6, ICIQ-SF, and ISI scores in all groups (p<0.05). The maximum voluntary contraction (MVC) of the PFMs increased in group 2 (p=0.002), whereas both the MVC of PFMs and PFM contraction during Valsalva increased in group 3 (p=0.011 and p=0.042).

CONCLUSIONS

Regardless of the teaching methods, the Knack maneuver and education programs were effective on urinary symptoms in women with mild to moderate SUI. The Knack maneuver training with vaginal palpation and verbal instruction improved MVC of PFMs. All three different teaching methods might be used in SUI treatment programs.

Pelvic Floor Support and Symptoms 1 Year Postpartum in Relation to Excess Body Habitus Before, During and After First Vaginal Birth

IMPORTANCE

Obesity may be a modifiable risk factor for pelvic floor disorders.

OBJECTIVES

The objective of this study is to determine associations between weight, weight changes, and cumulative exposure to excess body mass index (BMI) from prepregnancy to 1 year postpartum on pelvic floor support and symptoms 1 year after first vaginal birth.

STUDY DESIGN

In 645 primiparous women who gave birth vaginally, we assessed anatomic pelvic floor support, pelvic floor symptoms and BMI at the third trimester, 5 - 10 weeks, and 1 year postpartum; we also assessed BMI prepregnancy and predelivery. Using multivariable models, we determined associations between pelvic floor outcomes 1 year postpartum and BMI quartiles at different timepoints, gestational weight gain, and postpartum weight retention. We evaluated associations between stress urinary incontinence (SUI) and moderate/severe urinary incontinence (UI) 1 year postpartum and cumulative excess BMI from prepregnancy to 1-year postpartum (BMI1year).

RESULTS

Body mass index was not associated with anatomic support, composite symptom burden, overactive bladder, anal incontinence, or constipation at any timepoint. Gestational weight gain and postpartum weight retention were not associated with any 1-year outcome. Body mass index at every timepoint was positively associated with SUI and moderate/severe UI; BMI1year was most predictive. Cumulative excess BMI was positively associated with SUI and moderate/severe UI but only slightly more predictive of these outcomes than BMI1year alone.

CONCLUSIONS

Body mass index over the pregnancy trajectory was not associated with outcomes other than UI. The small advantage of cumulative exposure to excess BMI over BMI1year in predicting SUI and moderate/severe UI suggests that BMI1year adequately captures risk of these 1-year outcomes.

Perioperative and Long-Term Anatomical and Subjective Outcomes of Laparoscopic Pectopexy and Sacrospinous Ligament Suspension for POP-Q Stages II-IV Apical Prolapse

The aim of this paper was to analyze perioperative and long-term outcomes in 114 women undergoing surgery for POP-Q ≥ 2 apical prolapse: sacrospinous ligament colpo/hysteropexy (SSLF/SSHP)—61; laparoscopic pectopexy (LP)—53. Validated questionnaires (PGI-I, ISI, #35 EPIQ, PFIQ-7, PFDI-20) were completed at baseline and follow-up. POP-Q stages II, III and IV were diagnosed in 1 (0.9%), 84 (73.7%) and 29 (25.4%) patients, respectively. Mean operative time and hospital stay were 151.8 ± 36.2 min/2.6 ± 1.1 days for LP and 69 ± 20.4 min (p < 0.001)/2.7 ± 1.0 days for SSLF. Severe intraoperative complications occurred in two (1.8%) patients. Mean follow-up was 26.9 ± 12 and 37.3 ± 17.5 months for LP and SSLF, respectively. At follow-up, significant improvement for all POP-Q points was observed in both groups (p < 0.001). Shortening of total vaginal length was found in both groups, but predominantly in SSLF patients (p = 0.01). The sensation of vaginal bulge (EPIQ) was reduced, and total PFDI-20 and PFIQ-7 scores improved (p < 0.04) in both groups. Subjective success was reported by 40 (75.5%) LP and 44 (72.1%) SSLF patients. ISI detected no deterioration in urinary incontinence. PGI-I, PFDI-20, #35 EPIQ, PFIQ-7 and ISI did not differ between the groups. In conclusion both, SSLF and LP for apical prolapse generate good anatomical and subjective outcomes, with protective effect on the anterior compartment observed for LP.

Long-term Urinary Outcomes After Transvaginal Uterovaginal Prolapse Repair With and Without Concomitant Midurethral Slings

IMPORTANCE

Many health care providers place concomitant midurethral slings during pelvic organ prolapse repair, yet growing evidence supports staged midurethral sling placement.

OBJECTIVES

The aim of this study was to compare urinary function after transvaginal uterovaginal prolapse repair with and without midurethral sling.

STUDY DESIGN

Secondary analysis of the Study of Uterine Prolapse Procedures Randomized Trial (hysterectomy with uterosacral ligament suspension vs mesh hysteropexy). Our primary outcome was Urinary Distress Inventory score (UDI-6) through 5 years compared between women with and without a concomitant sling within prolapse repair arms. Sling effect was adjusted for select clinical variables and interaction terms (α = .05).

RESULTS

The sling group included 90 women (43 hysteropexy, 47 hysterectomy), and the no-sling group included 93 women (48 hysteropexy, 45 hysterectomy). At baseline, the sling group reported more bothersome stress (66% vs 36%, P < 0.001) and urgency incontinence (69% vs 48%, P = 0.007). For hysteropexy, there were no significant long-term differences in UDI-6 scores or bothersome urine leakage between sling groups. For hysterectomy, women with sling had better UDI-6 scores across time points (adjusted mean difference, -5.1; 95% confidence interval [CI], -9.9 to -0.2); bothersome stress and urgency leakage were less common in the sling group (stress adjusted odds ratio, 0.1 [95% CI, 0.0-0.4]; urge adjusted odds ratio, 0.5 [95% CI, 0.2-1.0]). Treatment for stress incontinence over 5 years was similar in the sling (7.9%) versus no-sling (7.6%) groups.

CONCLUSIONS

Five-year urinary outcomes of concomitant midurethral sling may vary by type of transvaginal prolapse surgery, with possible benefit of midurethral sling at the time of vaginal hysterectomy with apical suspension but not after mesh hysteropexy.

Urinary incontinence and health burden of female patients in China: Subtypes, symptom severity and related factors

AIM

Urinary incontinence (UI) causes long-term physical and psychological suffering to patients. Risk factors for different UI subtypes and symptom severity are still unclear, as well as their associations. We aimed to examine the potential influencing factors of UI episodes, UI severity and UI subtypes, and the associations among them.

METHODS

A total of 611 women were recruited in Shantou, China. Clinical and demographic data were collected through electronic medical records, measurements and self-reports. UI diagnosis, subtypes and symptom severity were confirmed according to international uniform standards. The health burden of UI was evaluated by the Incontinence Impact Questionnaire. Multivariate logistic and linear regression models were carried out to examine the potential risk factors and associations among UI subtypes, symptom severity, and health burdens.

RESULTS

Age, body mass index, comorbidity, lower urinary tract symptoms and constipation were associated with UI episodes and UI severity. Mixed UI patients had worse severity than urgency UI and stress UI, especially in leak times/week and daily life obstructing. Mixed UI patients also had higher health burdens, including mental health burdens, than urgency UI and stress UI patients. UI severity was positively associated with higher health burdens (β = 0.46, 95% CI 0.34-0.60), especially in physical activities, travel and social relationship burden (β = 0.61, 95% CI 0.40-0.85; β = 0.55, 95% CI 0.19-0.76; β = 0.65, 95% CI 0.38-0.91; respectively).

CONCLUSIONS

Age, body mass index, comorbidity, somnipathy and constipation were associated with UI episodes and symptom severity. Mixed UI showed the highest symptoms severity and health burdens. Worse UI severity increased the patient's physical health burden, but was not obvious for mental health burden. Geriatr Gerontol Int 2022; 22: 219-226.

Relative and Maximal Intra-abdominal Pressure and Postpartum Pelvic Floor Outcomes in Primiparas Delivered Vaginally

OBJECTIVES

This study aimed to explore associations between relative and maximal intra-abdominal pressure (IAP) on pelvic floor outcomes in primiparas delivered vaginally.

METHODS

At 5-10 weeks and 1 year postpartum, we measured absolute IAP by vaginal sensor while participants lifted a weighted car seat (IAPLIFT) and performed isometric trunk flexion endurance (IAPTFE) and seated maximal strain (IAPSTRAIN). Primary outcomes, completed 1 year postpartum, included worse pelvic floor support (descent to or beyond the hymen) and positive symptom burden (bothersome symptoms in ≥2 of 6 domains on the Epidemiology of Prolapse and Incontinence Questionnaire). We calculated relative IAP (as absolute IAP/IAPSTRAIN).

RESULTS

Of 542 participants, 9.7% demonstrated worse support and 54.3% demonstrated symptom burden at 1 year postpartum. In multivariable analyses, absolute IAPLIFT and absolute IAPTFE at 5-10 weeks postpartum were not associated with worse support. As relative IAP at 5-10 weeks increased, the prevalence of worse support decreased (prevalence ratio [PR] of 0.77 [95% confidence intervals (CIs), 0.63-0.94] and PR of 0.79 [95% CI, 0.67-0.93]) per 10% increase for relative IAPLIFT and relative IAPTFE, respectively. This was largely due to IAPSTRAIN, which increased the prevalence of worse support (PR, 1.15 [95% CI, 1.06-1.25]) per 10 cm H2O increase. One year postpartum, only IAPSTRAIN increased the prevalence of worse support (PR, 1.11 [95% CI, 1.02-1.20]) per 10 cm H2O. Of all IAP measures at both time points, only absolute IAPLIFT at 1 year significantly increased the prevalence of symptom burden (PR, 1.11 [95% CI, 1.05-1.18]) per 10 cm H2O.

CONCLUSIONS

This exploratory analysis suggests that postpartum IAPSTRAIN may increase the prevalence of worse support in primiparas delivered vaginally.

Validation of an obstetric fistula screening questionnaire: a case-control study with clinical examination

Background

Obstetric fistula (OF) is a significant cause of maternal morbidity in lower resource settings where women experience obstructed labor without timely access to skilled obstetric care. The true prevalence of OF is unknown; however, it is estimated to affect 2 to 3.5 million women globally. The Demographic and Health Surveys’ (DHS) Fistula Module includes the OF symptom questions most frequently used for prevalence estimates, but these questions have not been validated. The aim of this study is to validate a symptom-based screening questionnaire for OF, including a question in the DHS’ Fistula Module.

Methods

With an international panel of fistula surgeons, we developed and face-validated a screening questionnaire that assessed for symptoms of lower urinary tract fistula (LUTF) and lower gastrointestinal tract fistula (LGTF), as well as urinary and fecal incontinence (UI, FI). We evaluated the discriminative ability of the questionnaire using a case–control study design in a 1:2:2 ratio: cases were parous women with fistula confirmed on examination, controls included parous women without fistula on examination, with and without UI symptoms. All women underwent screening for fistula symptoms and a physical examination, with examiners blinded to screening results.

Results

Of the 367 Rwandan women who completed the questionnaires and underwent clinical examination, 59 women had LUTFs and 34 had LGTFs, 274 women were classified as controls with and without symptoms of UI. All LUTF screening questions performed well, including the DHS fistula question. The combination of two LUTF screening questions had the highest sensitivity (100%; 95% CI 94%, 100%), specificity (96%; 95% CI 93%, 98%), and area under the curve (AUC) (0.98). The combination of a LGTF screening question and FI question demonstrated the highest sensitivity (97%; 95% CI 85%, 100%), specificity (98%; 95% CI 95%, 99%) and AUC (0.98).

Conclusions

Our OF screening questionnaire, including the DHS fistula question, demonstrated high sensitivities, specificities, and AUC.

Supplementary Information

The online version contains supplementary material available at 10.1186/s12978-021-01317-2.

Obstetric fistula (OF) is a birth injury which may occur in women living in lower resource settings who experience obstructed labor (not progressing normally) without access to skilled obstetric care. This injury causes a woman to constantly leak urine and/or feces from her birth canal. As OF affects poor women who live far from healthcare it is difficult to fully understand how many women worldwide have an OF. Furthermore, although some Demographic and Health Surveys (DHS) include OF symptom questions, the accuracy of these questions in identifying women with OF has not been studied.

To more accurately determine which women may have an OF, we developed an OF screening questionnaire after consulting OF experts worldwide, which included a DHS OF question. We asked women from Rwanda this questionnaire and then examined these women to see if they have OF. Through this process we identified 59 women with a LUTF, 34 with a LGTF, and 274 without an OF. The best performing questions were able to identify women with LUTF 100% of the time and women with LGTF 97% of the time. We also showed that one DHS question detects women with LUTF and LGTF 100% and 85% of the time, respectively. Public health officials can now use the questions we studied to more accurately estimate how many women worldwide have OF, and best direct resources and skilled health care workers to the areas with the greatest need.

Updated Prevalence of Urinary Incontinence in Women: 2015-2018 National Population-Based Survey Data

OBJECTIVES

This study aimed to update estimates of urinary incontinence (UI) prevalence and associated risk factors for adult women in the United States, using the National Health and Nutrition Examination Survey (NHANES).

METHODS

We used descriptive analysis of 2015-2018 NHANES weighted data for women to estimate prevalence and characterize UI types and severity. Logistic regression modeling determined adjusted associations with UI.

RESULTS

Complete data were available for 5,006 women. In weighted analyses, 61.8% had UI, corresponding to 78,297,094 adult U.S. women, with 32.4% of all women reporting symptoms at least monthly. Of those with UI, 37.5% had stress urinary incontinence, 22.0% had urgency urinary incontinence, 31.3% had mixed symptoms, and 9.2% had unspecified incontinence. The prevalence of moderate or more severe UI by Sandvik Severity Index was 22.1%, corresponding to 28,454,778 adult U.S. women. In multivariate models, increasing age, body mass index ≥25, prior vaginal birth, anxiety, depression, functional dependence, and non-Hispanic White ethnicity and race were associated with any and moderate UI. Urinary incontinence was not associated with diabetes, education level, prior hysterectomy, smoking status, physical activity level, or current pregnancy status.

CONCLUSIONS

More than 60% of community-dwelling adult women in the United States experience any UI and an increase from prior estimates (38%-49%) using NHANES data from 1999 to 2004; more than 20% experience moderate or more severe UI. Increases in UI prevalence may be related to population aging and increasing obesity prevalence. Age greater than 70 years, body mass index >40, and vaginal birth had the strongest association with UI in multivariate modeling.

Longitudinal patterns of urinary incontinence and associated predictors in women with type 1 diabetes

AIMS

Urinary incontinence (UI) in women is a dynamic condition with numerous risk factors yet most studies have focused on examining its prevalence at a single time. The objective of this study was to describe the long-term time course of UI in women with type 1 diabetes (T1D).

METHODS

Longitudinal data in women with T1D were collected from 568 women in the Epidemiology of Diabetes Interventions and Complications (EDIC) study, the observational follow-up of the Diabetes Control and Complications Trial (DCCT) cohort. Over a 12-year period, participants annually responded to whether they had experienced UI in the past year.

RESULTS

We identified four categories of UI in this population over time: 205 (36.1%) women never reported UI (no UI), 70 (12.3%) reported it one or two consecutive years only (isolated UI), 247 (43.5%) periodically changed status between UI and no UI (intermittent UI), and 46 (8.1%) reported UI continuously after the first report (persistent UI). Compared to women reporting no/isolated UI, women displaying the intermittent phenotype were significantly more likely to be obese (OR: 1.86, 95% CI 1.15, 3.00) and report prior hysterectomy (OR: 2.57, 95% CI: 1.39, 4.77); whereas women with persistent UI were significantly more likely to have abnormal autonomic function (OR: 2.36, 95% CI: 1.16-4.80).

CONCLUSIONS

UI is a dynamic condition in women with T1D. Varying risk factors observed for the different phenotypes of UI suggest distinctive pathophysiological mechanisms. These findings have the potential to be used to guide individualized interventions for UI in women with diabetes.

Antenatal pelvic floor muscle training and urinary incontinence: a randomized controlled 7-year follow-up study

Introduction and hypothesis

Urinary incontinence is common postpartum. Our aims were to assess whether antenatal exercise including pelvic floor muscle training (PFMT) has long-term effects on urinary incontinence (UI) and to explore factors associated with UI 7 years postpartum.

Methods

A follow-up of a two-centre randomized controlled trial performed at St. Olavs Hospital and Stavanger University Hospital, Norway. In the original trial women were randomized to a 12-week structured exercise protocol including PFMT or standard antenatal care during pregnancy. Link to an electronic questionnaire was sent by postal mail 7 years postpartum. Prevalence of UI was assessed with Sandvik severity index and compared between groups. Factors associated with UI were studied using multivariable logistic regression analysis.

Results

The response rate was 35% (298/855). UI was reported by 78 (51%) in the intervention group and 63 (57%) in the control group (p = 0.539). In the multivariable logistic regression analyses, women with UI at inclusion had a five-fold increase in odds of UI at 7 years (OR 5.4, 95% CI 2.6, 11.5). Engaging in regular exercise was not significantly associated with UI at 7 years; however, UI was associated with lower exercise intensity (OR 2.4, 95% CI 1.2, 4.6).

Conclusions

We found no group differences of antenatal exercise including PFMT on UI after 7 years among the responders. UI in pregnancy increased the risk of long-term UI. Regular exercise was not associated with UI at 7 years; however, women with UI were more than twice as likely to exercise at lower intensity than continent women.

Correlation between the Incontinence Severity Index (ISI) and the quality of life dimensions of the King's Health Questionnaire (KHQ) in German-speaking urinary incontinent women

BACKGROUND

The Incontinence Severity Index (ISI) is a patient questionnaire to ascertain severity of urinary incontinence (UI) via two items. The aim of this study was to translate the ISI into German, to compare it with the German-language King's Health Questionnaire (KHQ), an already validated German-language questionnaire within the scope of UI to measure condition-specific quality of life (QoL), and to gain more insights into association between symptom severity and QoL in German-speaking women affected.

METHODS

A total of 161 urinary incontinent women completed the ISI and the KHQ. Mean scores of the KHQ domains were computed and separated into severity-groups ascertained by the ISI (slight, moderate, severe, and very severe). Differences between severity-groups were examined using Kruskal-Wallis and Mann-Whitney U test. Correlation between ISI and KHQ were computed using Spearman's correlation coefficient to investigate construct validity of the ISI as well as association between symptom severity and QoL.

RESULTS

Overall, mean scores of the KHQ domains increased with increasing severity level. A consistent significant increase was found in role, physical, and social limitations (p < 0.05). Furthermore, the ISI showed moderate to strong correlations with related domains (convergent validity) and weak correlations with non-related domains of the KHQ (discriminant validity).

CONCLUSIONS

Construct validity of the German-language ISI is acceptable. Therefore this study supports its use in German-speaking women but further studies have to be done to gain more comprehensive insights into its psychometric properties. Moreover, increasing symptom severity is associated with decreasing QoL, especially concerning role, physical, and social limitations.

Characterizing the Spectrum of Bladder Health and Lower Urinary Tract Symptoms (LUTS) Among Women: Results From the CARDIA Study

OBJECTIVES

To operationalize a new definition for bladder health, we examined the distribution of lower urinary tract symptoms (LUTS) and impact, along with associated factors, among women in the Coronary Artery Risk Development in Young Adults (CARDIA) study.

METHODS

We performed cluster analyses using validated LUTS symptom burden and impact scales collected between 2005-2006 and 2010-2011. We performed multinomial logistic regression analyses to evaluate cardiovascular factors (metabolic syndrome, cardiovascular health behaviors, and inflammation) between clusters after adjusting for covariates (demographic, obstetric/gynecologic, co-morbidities).

RESULTS

Among CARDIA women (median age 51, range 42-59) with complete LUTS data (n = 1302), we identified and compared 4 cluster groups: women who reported no or very mild symptoms and no impact on well-being (bladder health, 44%, n = 569), versus women with LUTS and negative impact on well-being ranging from mild (31%, n = 407), moderate (20%, n = 259), to severe (5%, n = 67). With each 1-point lower BMI (kg/m2), odds of membership in mild (OR 0.97, CI 0.95-0.99), moderate (OR 0.95, CI 0.93-0.98), and severe (OR 0.90, CI 0.88-0.94) LUTS cluster groups versus the bladder health group were lower. Compared to women with metabolic syndrome, women without metabolic syndrome had lower odds of membership in mild (OR 0.67, CI 0.45-0.99), moderate (OR 0.51, CI 0.33-0.79), and severe (OR 0.48, CI 0.24-0.94) LUTS cluster groups versus the bladder health group.

CONCLUSION

Two out of 5 midlife women met our definition of bladder health. Bladder health and cardiovascular health among women may share common factors, including lower BMI and the absence of metabolic syndrome.
