An investigation of the relationship between anxiety and depression and urge incontinence in women: Development of a psychological model

Steps toward identification of a novel cue-positive overactive bladder phenotype in women with high-bother urinary urgency

OBJECTIVE

The objective of this study was to investigate the relationship between situational cues (running water, stress, cold, etc.) and overactive bladder (OAB) symptoms.

METHODS

Women scheduled for urodynamic studies for clinical indications completed surveys to characterize OAB (ICIQ-OAB and OAB-V3) and responses to situational cues (validated long-form cues survey and a novel short-form cues survey). Participants were divided into two groups (Low-Bother urgency vs. High-Bother urgency), and OAB and cue survey responses were compared.

RESULTS

A total of 47 participants were enrolled in the study with 36 meeting inclusion criteria (15 Low-Bother and 21 High-Bother) with an overall mean age of 60.0 ± 10.0 years. The High-Bother urgency group scored significantly higher on multiple cue items in the long-form (P<0.05) and only "running water" in the short-form cues survey (P<0.05). In addition, "running water" was the only cue that was scored higher in both surveys (P<0.05).

CONCLUSIONS

This study showed that patients with High-Bother urgency may have increased symptom responses to environmental, mood, and cognitive cues. These findings suggest increased sensitivity to cues, especially "running water" in participants with bothersome OAB and the potential presence of a cue-specific OAB phenotype.

Association between overactive bladder and depression in American adults: A cross-sectional study from NHANES 2005-2018

BACKGROUND AND AIM

Overactive bladder (OAB) and depression are both common disorders and there is research suggesting an association between the two, but there is a lack of studies with large samples. The aim of this study is to investigate the association between OAB and depressive symptoms.

METHODS

We used data from the National Health and Nutrition Examination Survey (NHANES) database for the period 2005 to 2018. OAB was characterized by the Overactive Bladder Symptom Score (OABSS, score > 3) and depression was diagnosed by the Patient Health Questionnaire (PHQ-9, score ≥ 10). There were three models employed in our analysis: (1) Crude model was unadjusted; (2) Model 1 was adjusted for age, sex, race/ethnicity, educational level, and marital status; (3) Model 2 was adjusted for factors in Model 1 plus the remained potential covariates. We used survey-weighted logistic regression models to assess the association between OAB and depression. Subsequently, subgroup analyses and smoothed curve analyses were used to evaluate the reliability of the findings.

RESULTS

Finally, a total of 6612 participants were included in our study, consisting of 1005 participants with diagnosis of OAB and 5607 participants without diagnosis of OAB. After adjusting for all covariates, there was a significant positive association between OAB and depression (OR: 2.89, 95 % CI: 1.91, 4.37). The severity of OAB was also positively associated with depression. Compared to participants without OAB, the fully adjusted ORs for depression were 2.76 (95 % CI: 1.64, 4.65) for those with mild OAB, 3.79 (95 % CI: 1.68, 8.55) for those with moderate OAB, and 5.21 (95 % CI: 1.39, 19.53) for those with severe OAB.

CONCLUSIONS

This study revealed a strong association between OAB and depression and a progressive increase in the risk of depression as the severity of OAB (mild, moderate, and severe) increased. Therefore, it is important for clinicians to recognize the assessment of OAB symptoms in patients who are at risk for or have developed depressive symptoms, as well as the mental health of patients with OAB.

Prevalence of depression and anxiety in women with pelvic floor dysfunctions: A systematic review and meta-analysis

BACKGROUND

Female pelvic floor dysfunction (PFD) is a common condition affecting the emotional well-being of women.

OBJECTIVE

To estimate the prevalence of depressive and anxiety symptoms in women with PFD. SEARCH STRATEGY, SELECTION CRITERIA, DATA COLLECTION AND ANALYSIS: Following prospective registration (PROSPERO CRD42022362095) we conducted a search of three electronic databases (PubMed, Web of Science and Scopus) from inception to April 2023 without language restriction to capture studies reporting the prevalence of depression/anxiety among women with PFD (chronic pelvic pain [CPP], urinary incontinence [UI], pelvic organ prolapse [POP], and/or fecal incontinence [FI]). Only studies with validated tools were included. Data extraction and study quality assessment were performed by two independent reviewers. Stratifying by type of PFD, rates of depression and anxiety were pooled using random effects model computing 95% confidence interval (CI) and assessing heterogeneity using the I2 statistic. Funnel plots were used to detect potential reporting biases and small-study effects.

MAIN RESULTS

The search yielded 767 articles, from which 54 studies containing 632 605 women were included. All the studies were high quality. The prevalence of depression was: CPP 26.8% (95% CI: 19.2-34.4, I2 = 98.7%; 12 studies, 4798 participants with 491 cases; Egger's P value = 0.009); UI 26.3% (95% CI: 19.4-33.2, I2 = 99.9%; 26 studies, a total of 346 114 participants with 25 050 cases; Egger's P value = 0.944); POP 34.9% (95% CI: 24.3-45.6, I2 = 68%; three studies, 297 participants with 104 cases; Egger's P value = 0.973); and FI 25.3% (95% CI: 0.68-49.9, I2 = 99.7%; six studies, 14 663 participants with 1773 cases; Egger's P value = 0.780). The prevalence of anxiety was: CPP 29.5% (95% CI: 16.3-42.7, I2 = 97.7%; nine studies, 2483 participants with 349 cases; Egger's P value = 0.001); UI 46.91% (95% CI: 39.1-54.6, I2 = 99.6%; 11 studies, 198 491 participants with 40 058 cases; Egger's P value = 0.337); and POP 28% (95% CI: 13.6-42.4, I2 = 89%; three studies with 355 participants with 90 cases; Egger's P value = 0.306).

CONCLUSION

The prevalence of mental health illness was variable in the different types of PFDs. This meta-analysis helps quantify the burden of depression and anxiety in PFD and will help inform the policies regarding screening of emotional well-being by healthcare professionals engaged in care of women with PFD.

The correlation between academic stress, overactive bladder syndrome (OAB) and quality of life among healthy university students: A cross-sectional study

INTRODUCTION

This study aims to assess the presence of overactive bladder syndrome (OAB), academic stress, and their impact on quality of life (QoL) of healthy university students.

METHODS

A cross-sectional study recruited university students from different academic streams, between January 2021 to December 2021. Demographics, overactive bladder-validated 8 questionnaire (OAB-V8), International Consultation on Incontinence Questionnaire Overactive Bladder Module (ICIQ-OAB) questionnaire, and Perception of Academic Stress (PAS) scale were collected. The correlation between the variables was assessed using the Social Sciences Statistical Package (SPSS) version 21.

RESULTS

Three hundred and 89 people met the inclusion criteria. There were 241 (62%) females, and 248 (63.8%) of the students were under the age of 22. Four academic streams were included: Engineering 96 (24.7%), Humanities 121 (31.1%), Medicine 85 (21.8%) and Nursing 87 (22.4%). OAB was found among 103 (26%) students. The mean OAB-V8 score was 5.8 ± 6.6. The mean PAS scale was 53.9 ± 9.4. The mean ICIQ-OAB score was 1.5 (0-9). Male gender 62 (60%), smoking 42 (40.8%), academic stream (Humanity 40 (38.8%)) and year (third and fourth-year students 34 (33%) and 33 (32%), respectively) have a statistically significant positive correlation with OAB (p < 0.001). Humanity stream (mean rank 169.2) and junior students (first and second years with mean rank of 174 and 177), respectively, had high level of academic stress and low PAS scale. There is a weak but statistically significant inverse correlation between OAB and the PAS scale (r = -0.211) (p < 0.001).

CONCLUSION

OAB is prevalent among healthy university students and is directly related to academic stress. Both OAB and academic stress have impact on quality of life. We hope this study will help to raise awareness of OAB among university students to early identify and treat such a condition, avoiding unnecessary bother among healthy university students.

A study to untangle the puzzle of urinary incontinence and frailty co-occurrence among older adults: The roles of depression and activity engagement

AIMS

To explore the co-occurrence of urinary incontinence and frailty by testing the roles of depression and activity engagement guided by the mechanisms of common cause and interaction pathways.

DESIGN

A secondary analysis of a 1-year three-wave panel data collected from older nursing home residents in China.

METHODS

Changes in depression and activity engagement were regressed on urinary incontinence and frailty incidence underpinned by the common cause mechanism of chronic conditions co-occurrence, and these changes were also taken as mediators linking from frailty to urinary incontinence incidence supported by the interaction pathways' mechanism.

RESULTS

A total of 348 older adults were included in this study, and 55.7% were women. The co-occurrence of urinary incontinence and frailty was found in 16.7% of the participants at baseline. Older adults with sole frailty at baseline had almost twice the rate of incident urinary incontinence (32.7%) compared with those without (16.7%) over a 1-year period. The subsample analyses showed that changes in depression and activity engagement failed to significantly predict the incidence of urinary incontinence and frailty. The mediating roles of these changes linking frailty to urinary incontinence incidence were also not statistically significant.

CONCLUSION

The co-occurrence of urinary incontinence and frailty is prevalent in older nursing home residents. Older adults with frailty at baseline are more likely to develop urinary incontinence a year later. The common cause and interaction pathways mechanisms for the co-occurrence of urinary incontinence and frailty were not verified with changes in depression and activity engagement.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The phenomenon of urinary incontinence and frailty co-occurrence should be given extreme emphasis. Although statistically significant findings on the roles of depression and activity engagement were not inferred, this study provides multiple possibilities for future studies to test and depict a clear picture of this co-occurrence.

IMPACT

What problem did the study address? This study was designed to test the roles of depression and activity engagement in predicting the incidence of urinary incontinence and frailty, and the mediating roles in linking frailty to urinary incontinence incidence. What were the main findings? Despite the methodological pitfalls in literature have been addressed, neither depression nor activity engagement would significantly predict the incidence of urinary incontinence and frailty in older adults. Their mediating roles in linking frailty to urinary incontinence incidence were also not significant. Where and on whom will the research have an impact? Our findings add important pieces of evidence to promote researchers' understanding and provide an important basis for untangling the puzzle of urinary incontinence and frailty co-occurrence.

REPORTING METHOD

The report of this study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement guidelines.

The brain, gut, and bladder health nexus: A conceptual model linking stress and mental health disorders to overactive bladder in women

OBJECTIVE

A small, but growing literature links stressors and mental health disorders (MHDs) across the life course to overactive bladder (OAB) and urinary incontinence symptoms. Mechanisms by which stressors and MHDs may impact bladder health are not fully understood, limiting novel prevention and treatment efforts. Moreover, potential biopsychosocial mechanisms involving the brain and gut have not been considered in an integrated, comprehensive fashion.

METHODS

Members of the prevention of lower urinary tract symptoms Research Consortium developed conceptual models to inform research on biopsychosocial mechanisms through which stress and MDHs may impact bladder health among girls and women, focusing on brain and gut physiology.

RESULTS

Two conceptual models were developed-one to explain central (brain-based) and peripheral (gut-based) mechanisms linking stressors and MHDs to OAB and bladder health, and one to highlight bidirectional communication between the brain, gut, and bladder. Traumatic events, chronic stressors, and MHDs may lead to a maladaptive stress response, including dysregulated communication and signaling between the brain, gut, and bladder. Gut bacteria produce molecules and metabolites that alter production of neurotransmitters, amino acids, short-chain fatty acids, and inflammatory immune response molecules that mediate communication between the gut and brain. Microbiota signal neurogenesis, microglia maturation, and synaptic pruning; they also calibrate brain-gut-bladder axis communication through neurotransmission and synaptogenesis, potentially influencing bladder symptom development. Life course trajectories of risk may be prevented or interrupted by central and peripheral resources for neuropsychological resilience.

CONCLUSIONS

Depicted pathways, including brain-gut-bladder communication, have implications for research and development of novel prevention and treatment approaches.

Psychosocial Factors Associated with Lower Urinary Tract Symptoms One Year Postpartum

Pregnancy carries substantial risk for developing lower urinary tract symptoms (LUTSs), with potential lifelong impacts on bladder health. Little is known about modifiable psychosocial factors that may influence the risk of postpartum LUTSs. We examined associations between depressive symptoms, perceived stress, and postpartum LUTSs, and the moderating effects of perceived social support, using data from a cohort study of Expect With Me group prenatal care (n = 462). One year postpartum, 40.3% participants reported one or more LUTS. The most frequent LUTS was daytime frequency (22.3%), followed by urinary incontinence (19.5%), urgency (18.0%), nocturia (15.6%), and bladder pain (6.9%). Higher odds of any LUTS were associated with greater depressive symptoms (adjusted odds ratio (AOR) 1.08, 95% confidence interval (CI) 1.04-1.11) and perceived stress (AOR 1.12, 95% CI 1.04-1.19). Higher perceived social support was associated with lower odds of any LUTS (AOR 0.94, 95% CI 0.88-0.99). Perceived social support mitigated the adverse effects of depressive symptoms (interaction AOR 0.99, 95% CI 0.98-0.99) and perceived stress (interaction AOR 0.97, 95% CI 0.95-0.99) on experiencing any LUTS. Greater depressive symptoms and perceived stress may increase the likelihood of experiencing LUTSs after childbirth. Efforts to promote bladder health among postpartum patients should consider psychological factors and social support.

Association of Urinary Incontinence and Depression: Findings From the National Health and Nutrition Examination Survey

OBJECTIVE

To evaluate the association between urinary incontinence and depression. An estimated 21 million adults in the United States (U.S.) reported at least one major depressive episode. Urinary incontinence has a well-described negative impact on quality of life.

METHODS

We included respondents aged ≥20 who participated in the 2017 - March 2020 National Health and Nutrition Examination Survey cycles. Our dichotomous outcomes were depression and clinical depression. The predictor variable urinary incontinence was assessed using the validated incontinence severity index. We fitted an adjusted multivariable logistic regression and performed interaction analysis for urinary incontinence and our variable of interest.

RESULTS

Among a weighted sample of 233.5 million people (unweighted 8256), 19.9 million (8.5%) reported depression (P < .001). The weighted population was 48.6% male, 55.2% married, and 63.4% non-Hispanic White (all P < .001). Moderate and severe urinary incontinence was associated with depression (adjusted odds ratio [aOR] 2.3; 95%CI [1.5-3.3]; aOR 3.8; 95%CI [2.5-3.3]; P < .001). No association was observed between urinary incontinence and clinical depression. Interaction analysis showed that men (aOR 3.62; 95%CI [2.13-6.15]; Pint<.001) and participants at the lowest socioeconomic status (aOR 2.2; 95%CI [1.3-3.71]; Pint=.005) with moderate/severe urinary incontinence had higher odds of depression than their continent counterparts.

CONCLUSION

We report that urinary incontinence is an independent predictor of depression in a nationally representative survey for men and those in the lowest socioeconomic tier. The association is most prominent among men and the socioeconomically disadvantaged population. This suggests that treatment for urinary incontinence may be important tool to reduce depression in the general population.

The biopsychosocial impacts of anxiety on overactive bladder in women

AIMS

Links between emotional state and the bladder have long been recognized, as psychological comorbidity is a common feature of overactive bladder (OAB). However, how psychological factors might contribute to the development and severity of OAB remains unclear. Therefore, we sought to examine the effect of anxiety on OAB with a specific focus on bladder hypersensitivity.

METHODS

In a sample of 120 adult women with OAB, we compared those with at least mild anxiety (PROMIS Anxiety score ≥55) to those with lower anxiety. Analyses focused on patient-reported questionnaires assessing urinary symptom severity and quality of life, psychological stress symptoms, general somatic symptoms, and results of quantitative sensory testing (QST), including temporal summation to heat pain (TSP). TSP was used to index elevated C-fiber responsiveness (i.e., central sensitization).

RESULTS

Thirty-six (30%) women had at least mild anxiety. While there were no group differences for urinary symptom severity, more anxious women reported worse OAB-specific quality of life, greater psychological stress burden, higher stress reactivity, and greater somatic symptoms. On QST, there were no differences between anxiety groups for pain threshold (43.6 ± 3.1°C vs. 44.0 ± 3.1°C, p = 0.6) and tolerance (47.3 ± 1.5°C vs. 47.4 ± 1.6°C, p = 0.7). However, those with anxiety had significantly higher TSP than those without anxiety (6.0 ± 4.8 vs. 3.7 ± 3.9, p = 0.006), indicating greater central sensitization.

CONCLUSIONS

Women with OAB and at least mild anxiety symptoms reported greater psychosocial burdens (i.e., psychological stress, stress reactivity, OAB-specific QOL) and somatic symptom severity and demonstrated greater central sensitization on QST than those without anxiety. These findings support the hypothesis that anxiety and psychological stress impact hypersensitivity mechanisms that may underlie and contribute to OAB, although further research is needed to better understand how and to what extent.

Life satisfaction and anxiety in women with urinary incontinence

BACKGROUND

This study aimed to examine satisfaction with life in patients with urinary incontinence and patients who underwent an operative procedure due to urinary incontinence.

METHODS

Women with a medical indication for surgery due to urinary incontinence problems but who had not yet had surgery (N = 110) and same-age women who had had a surgical procedure for urinary incontinence (N = 101) completed a set of questionnaires.

RESULTS

The results showed that women with urinary incontinence had significantly higher life satisfaction than women who underwent the operation. Contrary to expectations, women with urinary incontinence problems reported equal levels of life satisfaction to a comparable sample of postmenopausal normative women. Higher levels of life satisfaction were related to higher education level, employment, higher perceived socioeconomic level, and urban place of living.

CONCLUSION

It is important for physicians to address the problem of urinary incontinence with their patients and to examine the present anxiety symptoms, given that they may affect their subjective wellbeing.

Stress-Induced Changes in Trophic Factor Expression in the Rodent Urinary Bladder: Possible Links With Angiogenesis

PURPOSE

Substantive evidence supports a role of chronic stress in the development, maintenance, and even enhancement of functional bladder disorders such as interstitial cystitis/bladder pain syndrome (IC/BPS). Increased urinary frequency and bladder hyperalgesia have been reported in rodents exposed to a chronic stress paradigm. Here, we utilized a water avoidance stress (WAS) model in rodents to investigate the effect of chronic stress on vascular perfusion and angiogenesis.

METHODS

Female Wistar-Kyoto rats were exposed to WAS for 10 consecutive days. Bladder neck tissues were analyzed by western immunoblot for vascular endothelial growth factor (VEGF) and nerve growth factor precursor (proNGF). Vascular perfusion was assessed by fluorescent microangiography followed by Hypoxyprobe testing to identify regions of tissue hypoxia.

RESULTS

The expression of VEGF and proNGF in the bladder neck mucosa was significantly higher in the WAS rats than in the controls. There was a trend toward increased vascular perfusion, but without a statistically significant difference from the control group. The WAS rats displayed a 1.6-fold increase in perfusion. Additionally, a greater abundance of vessels was observed in the WAS rats, most notably in the microvasculature.

CONCLUSION

These findings show that chronic psychological stress induces factors that can lead to increased microvasculature formation, especially around the bladder neck, the region that contains most nociceptive bladder afferents. These findings may indicate a link between angiogenesis and other inflammatory factors that contribute to structural changes and pain in IC/BPS.

Mediating role of functional limitations in the association of urinary incontinence with depressive symptoms among middle-aged and older adults: The English Longitudinal Study of Aging

OBJECTIVE

To investigate the association of urinary incontinence with depressive symptoms, and to explore the mediating effect of functional limitations on this association.

METHODS

This cross-sectional study included 7039 adults aged 50 and over from the English Longitudinal Study of Aging (Wave 8). Urinary incontinence was defined as whether the participants experienced urinary incontinence in the past 12 months. Depressive symptoms were assessed based on the Center for Epidemiologic Studies-Depression Scale. Functional limitations included disability of activities of daily living, instrumental activities of daily living, mobility and large muscle groups limitation of the participants. Logistic regression based on Karlson/Holm/Breen (KHB) method was applied to estimate the association of urinary incontinence with depressive symptoms and explore the mediating effect of functional limitations.

RESULTS

Urinary incontinence was significantly associated with increased risk of depressive symptoms after controlling covariates (odds ratio = 1.75, 95 % confidence interval: 1.45-2.11). Functional limitations explained 36.96 % of this association.

CONCLUSION

Urinary incontinence might be associated with an increased risk of depressive symptoms among middle-aged and older adults and functional limitations partially mediate this association. Improving physically functional capacity might play an important role in preventing and managing depressive symptoms in elderly people with urinary incontinence.

Daily symptom associations for urinary urgency and anxiety, depression and stress in women with overactive bladder

INTRODUCTION AND HYPOTHESIS

Women with overactive bladder (OAB) report psychological distress, anxiety and depression, but short-term associations between these symptoms are poorly studied. Our objectives were to study daily associations between OAB symptoms and psychological symptoms and test whether these associations were stable when reassessed after 3 months. We hypothesized that OAB symptoms are positively associated with anxiety and depression symptoms over a short-term (daily) basis.

METHODS

Female patients with OAB [bothersome urgency and/or urgency urinary incontinence (UUI)] assessed OAB and mood symptoms at baseline and 3 months using a 3-day bladder diary and visual analog scale (VAS) ratings (0-100 mm) for anxiety, depression and stress. Daily OAB and mood symptom associations were tested using Spearman correlations. Generalized estimating equation (GEE) models tested associations between daily urgency scores and each psychological rating adjusting for covariates, time and a time-symptom interaction term.

RESULTS

Participants (n = 69) had mean (SD) age 63.3 (13.4) years. Baseline diary outcomes [median (IQR)/day] included day voids 8 (7-11), nocturia 0 (0-1), UUI episodes 1 (0-3) and urgency score 1.75 (1-2.25). Anxiety and depression diagnoses (dx) and treatment (tx) were common (anxiety dx 30.4%, tx 21.7%; depression dx 47.8%, tx 37.7%), but daily anxiety, depression and stress ratings were low [median (IQR) mm 10 (3-35), 5 (1-16), and 16 (4-39), respectively]. Daily urgency scores correlated with anxiety (r = 0.30-0.40, days 1-3, p ≤ 0.01 for all), depression (r = 0.24-0.35, p ≤ 0.05 all) and stress (r = 0.27-0.34, p ≤ 0.03 all). GEE models indicated no significant change in these associations between baseline and 3 months, and OAB treatment did not impact the associations.

CONCLUSIONS

Urgency scores were positively associated with same-day ratings of anxiety, depression and stress in OAB patients.

The Impact of Caffeine Intake on Mental Health Symptoms in Postmenopausal Females with Overactive Bladder Symptoms: A Randomized, Double-Blind, Placebo-Controlled Trial

Background: Caffeine has been associated with a dose-dependent variety of mental health changes, which have been found to precede or be a complication of overactive bladder (OAB) symptoms after menopause. The current study examines the effects of low and moderate caffeine intake on anxiety, depression, sleep, and stress in postmenopausal females with OAB. Materials and Methods: Eighty-one females were randomized in a prospective, double-blind, placebo-controlled study. Participants were allocated to 200 mg/day caffeine, 400 mg/day caffeine, and placebo capsules for 1 week each in a crossover design and evaluated using validated mental health questionnaires. Symptoms during each treatment phase were measured using Beck Anxiety and Depression Inventory, Insomnia Severity Index, and Perceived Stress Scale. Linear regression models were used to examine the impact of low (200 mg/day) and moderate (400 mg/day) dose of caffeine and placebo on mental health. Results: Fifty-six female participants finished the study. The mean age was 69.2 years (58.0-84.0 years). Two females dropped out during the treatment phase with 400 mg/day caffeine intake due to side effects associated with headaches and nausea. Moderate dose of caffeine showed a small positive effect on mental health, specifically a decrease in anxiety during 7 days of exposure (p < 0.05). Conclusions: Moderate caffeine use may decrease anxiety in postmenopausal patients with underlying OAB, whereas depression, insomnia, and perceived stress were not affected by low-to-moderate caffeine intake. Our results support that counseling efforts on moderate caffeine consumption in postmenopausal patients underline that low-to moderate caffeine intake may be appropriate and possibly beneficial unless contraindicated due to other underlying conditions. Clinical Trials Registration: clinicaltrials.gov (NCT02180048).

Impact of intravesical onabotulinumtoxinA (Botox) on sexual function in patients with overactive bladder syndrome: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

The association between overactive bladder (OAB) syndrome and sexual dysfunction is well documented. Intra-detrusor onabotulinumtoxinA (Botox) has proven to be effective treatment for OAB syndrome. Our aim was to examine the impact of intravesical Botox injection on sexual function in patients with OAB, by systematically reviewing the literature.

METHODS

We reviewed the literature for studies that reported a change in sexual function after Botox treatment in patients suffering from OAB. This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using pre-agreed keywords, from database inception to December 2020. Statistical analyses were performed using Review Manager (RevMan; v.5.4).

RESULTS

Initial results yielded 455 citations. Seven articles met our inclusion criteria. One article was double-reported, leaving 6 studies in the systematic review. Three observational before-and-after studies used the Female Sexual Function Index (FSFI) with sufficient information, and therefore were included in our meta-analysis. The pooled number of participants in all studies was 119 patients. In the meta-analysis, there was significant improvement in the following domains of the FSFI after Botox injection; desire (mean difference (MD) -0.51, p = 0.02), arousal (MD -0.86, p = 0.02), lubrication (MD -0.57, p = 0.03), orgasm (MD -0.65, p = 0.0003) and satisfaction (MD -0.46, p = 0.05). Pain was the only domain that did not show improvement (MD -0.07, p = 0.79). The total FSFI score was reported in 88 patients (two studies) showing significant improvement (MD -0.77, p = 0.006).

CONCLUSIONS

We report a systematic review of the effect of Botox treatment on sexual function in patients with OAB. Although studies are small, the results indicate a positive effect in patients with OAB.

Long-term functional and psychosocial outcome in adolescents and young adults treated for lower urinary tract dysfunction in childhood

BACKGROUND

Lower urinary tract dysfunction (LUTD) in childhood might affect lower urinary tract function and psychological wellbeing later in life. This study presents long-term functional outcome, psychological outcome and quality of life (QOL) of adolescents and young adults treated for childhood LUTD compared to healthy age-matched controls. In addition, association with past treatment outcomes is evaluated.

STUDY DESIGN

A single-centre cross-sectional study of former patients treated in childhood (currently 16-26 years old) was conducted. Participants completed a survey composed from validated questionnaires: the Overactive Bladder Questionnaire, the Hospital Anxiety and Depression Scale, the Pediatric Quality of Life Inventory and the Short Form 36 Health Survey.

RESULTS

Fifty-two former patients (out of 133) agreed to participate and returned the survey (mean age 21 ± 4.1 years). Sixty-nine control subjects were included (mean age 21 ± 2.9 years). Urinary tract symptoms were more common in former patients than controls. Storage symptoms more frequently reported were (urge) urinary incontinence, stress urinary incontinence (SUI) and nocturia. Voiding symptoms more frequently reported were intermittency and feeling of incomplete emptying, Fig. 1. There were no differences in urinary tract symptoms or urinary incontinence subdivided by childhood treatment outcome (complete response, partial response or no response), respectively p = 0.17 and p = 0.58. Results of the overactive bladder questionnaire revealed higher urinary symptom bother scores (score 14 versus 5 p < 0.01) and lower disease-specific QOL (score 95 versus 98 p = 0.02) in former patients compared to controls. General QOL and psychosocial wellbeing were not significantly different between the two groups. A childhood treatment duration extending 2,5 years was an independent prognostic factor for subsequent urinary tract symptoms later in life (OR = 1.5, 95% CI 1.1-2.0). Psychological comorbidity was more often present in former patients (35%) versus controls (10%), p < 0.01.

CONCLUSION

Adolescents and young adults treated for childhood LUTD are more prone to report urinary tract symptoms later in life, especially if treatment duration was extensive. However general QOL and psychosocial wellbeing later in life are not or only mildly affected.

Psychiatric History and Overactive Bladder Symptom Severity in Ambulatory Urogynecological Patients

Introduction and hypothesis: A link between psychiatric comorbidities and overactive bladder symptomatology has been suggested by preclinical and clinical studies. Given this, we hypothesized that a psychiatric history and current treatment with psychotropic medications could be related to the severity of overactive bladder and incontinence symptoms in patients referred to a tertiary care urogynecological center. Methods: One hundred and twenty-seven female patients diagnosed with an overactive bladder were screened for a lifetime history of psychiatric disorders and the type and number of psychotropic medications currently taken. The overall severity of overactive bladder symptoms was assessed using the Indevus Urgency Severity Scale. The severity and impact of urinary incontinence on the quality of life were quantified with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form. Urinary incontinence was further quantified with the aid of the Urinary Distress Inventory-6. The patients were screened for stress urinary incontinence using the Stamey Incontinence Score. Results: A psychiatric history, as well as current use of at least two psychotropic medications, was associated with increased severity of overactive bladder symptoms. A history of depression and current treatment with any selective serotonin reuptake inhibitor was associated with increased severity of stress urinary incontinence symptoms. Current treatment with other psychotropic medications, including sedative-hypnotics and drugs with anticholinergic properties was not related to the severity of overactive bladder and incontinence symptoms.

[Definition, epidemiology and impact of non-neurogenic overactive bladder]

INTRODUCTION

Overactive bladder (OAB) is a common condition with a significant functional impact in patients.

OBJECTIVE

To synthesize current knowledge on the definition, epidemiology and impact of OAB.

METHOD

A systematic literature review based on Pubmed, Embase, Google Scholar was conducted in June 2020.

RESULTS

OAB is defined by urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence, in the absence of urinary tract infection or other obvious pathology. In France, OAB affects 14 % of the general population and this prevalence increases with age. This condition is a source of major deterioration in patients' quality of life with a physical (falls, fractures, sleep disorders, fatigue), psychic (anxiety, depression) social (limitation of leisure, isolation) and economic impact.

CONCLUSION

The definition of OAB is standardized. OAB is a frequent condition and has significant functional consequences with a notable deterioration in quality of life.

Factors associated with the diagnosis of depression in women followed in gynecological practices in Germany

BACKGROUND

There are many diagnoses in the field of gynecology that can severely impact the lives of patients and that are associated with an increased risk of developing depression. The goal of this study was to investigate which gynecological diagnoses are associated with depression.

METHODS

This retrospective case-control study based on the Disease Analyzer database (IQVIA) included 5893 women aged 18 years or older with depression and 5893 age-matched pairs followed in 256 gynecological practices in 2019 (index date). A multivariate logistic regression model was used to study the association between 33 pre-defined diagnoses documented within five years prior to the index date and depression diagnosis.

RESULTS

In total, 9 diseases were significantly associated with diagnosis of depression. The strongest association was observed for breast cancer (Odds Ratio (OR: 2.11 (95% Confidence Interval (CI): 1.76-2.52)), followed by female infertility (OR: 1.91 (95% CI: 1.48-2.47)), cancer of female genital organs excl. breast (OR: 1.87 (95% CI: 1.32-2.66)), and sexual dysfunction (OR: 1.63 (95% CI: 1.27-2.09). Other diseases that showed a significant association with depression included endometriosis, mastodynia, candidiasis, infections with a predominantly sexual mode of transmission, and urinary incontinence. Patients with a higher number of different disorders were more likely to be diagnosed with depression (ORs from 1.40 for two disorders to 2.38 for >6 disorders as compared to no disorders).

CONCLUSION

A wide range of diseases documented in gynecologists' practices were associated with depression diagnosis. Understanding all of these associations may help gynecologists to refer women promptly to psychologists or psychiatrists who may help to manage depression in this population.

Systematic review and meta-analysis identify significant relationships between clinical anxiety and lower urinary tract symptoms

BACKGROUND

Lower urinary tract symptoms (LUTS), such as voiding symptoms, overactive bladder, and interstitial cystitis, and anxiety disorders are often comorbid conditions in patients. However, the existing evidence regarding the rates and nature of the co-occurrence of these conditions has not been systematically evaluated. The aim of this study was to examine these relationships.

METHODS

We conducted a systematic review and meta-analysis to examine the relationship between LUTS and anxiety. We searched for articles published from January 1990 to July 2019 in PubMed, CENTRAL, PsycINFO, and Google Scholar. Outcomes were anxiety-related disorders and symptoms (clinically significant anxiety) and LUTS. We performed random-effects meta-analyses, inspected funnel plots, and applied the Egger's test to evaluate publication bias. We followed PRISMA guidelines and recorded our protocol on PROSPERO (ID = CRD42019118607).

RESULTS

We identified 814 articles, of which 94 fulfilled inclusion criteria, and 23 had sufficient data for meta-analysis. The odds ratio (OR) for clinically significant anxiety among individuals with LUTS was 2.87 (95% CI: 2.38,3.46, p < .001). The OR for LUTS among individuals with clinically significant anxiety was 2.87 (95% CI: 1.07,7.74, p < .001), although very few studies examined this relationship. A large value of I² index suggests high heterogeneity between studies.

CONCLUSION

The results demonstrate a significant association between clinically significant anxiety and LUTS in both females and males. There were limited studies on younger individuals and on individuals ascertained for clinically significant anxiety, which should motivate further study in these areas. Understanding the co-occurrence of these conditions will lead to better prevention and interventions to ameliorate the progression of the symptoms and improve the quality of life. A thorough assessment of anxiety may provide more optimal care for LUTS patients.

Psychological/mental stress-induced effects on urinary function: Possible brain molecules related to psychological/mental stress-induced effects on urinary function

Exposure to psychological/mental stress can affect urinary function, and lead to and exacerbate lower urinary tract dysfunctions. There is increasing evidence showing stress-induced changes not only at phenomenological levels in micturition, but also at multiple levels, lower urinary tract tissues, and peripheral and central nervous systems. The brain plays crucial roles in the regulation of the body's responses to stress; however, it is still unclear how the brain integrates stress-related information to induce changes at these multiple levels, thereby affecting urinary function and lower urinary tract dysfunctions. In this review, we introduce recent urological studies investigating the effects of stress exposure on urinary function and lower urinary tract dysfunctions, and our recent studies exploring "pro-micturition" and "anti-micturition" brain molecules related to stress responses. Based on evidence from these studies, we discuss the future directions of central neurourological research investigating how stress exposure-induced changes at peripheral and central levels affect urinary function and lower urinary tract dysfunctions. Brain molecules that we explored might be entry points into dissecting the stress-mediated process for modulating micturition.

Association of urinary incontinence and depression or anxiety: a meta-analysis

Objective

We explored the relationship between urinary incontinence (UI) and depression or anxiety.

Methods

We searched the Cochrane Library, Embase, and PubMed for articles on the association between depression, anxiety, and UI. We calculated pooled 95% confidence intervals (CIs) and odds ratios (ORs).

Results

Twelve articles (31,462 participants) were included. The UI group had significantly higher depression and anxiety levels than the non-UI group (OR = 1.73, 95%CI: 1.64–1.82, I² = 75.5%). In subgroup analysis, depression and anxiety were significantly higher in participants with UI than in those without UI (OR = 1.95, 95%CI: 1.82–2.10, I² = 64.3% and OR = 1.54, 95%CI: 1.43–1.65, I² = 59.2%, respectively).

 In subgroup analysis by age, participants with UI had significantly higher depression and anxiety, regardless of age, than the non-UI group (OR = 1.59, 95%CI: 1.29–1.95, I² = 59.1% and OR = 1.98, 95%CI: 1.62–2.43, I² = 75.5%, respectively).

Conclusion

Patients with UI had significantly higher depression and anxiety levels than those without UI. Depression and anxiety were higher in patients with UI than in those without UI, regardless of age. Larger sample sizes and more high-quality studies are needed to validate our findings.

Risk factors for stress and urge urinary incontinence during pregnancy and the first year postpartum: a prospective longitudinal study

INTRODUCTION AND HYPOTHESIS

We examined obstetric and maternal-newborn factors and UI history for stress urinary incontinence (UI) and urge UI during pregnancy and the first year postpartum.

METHODS

This prospective cohort study included 1447 pregnant women who underwent prenatal examinations and completed an Incontinence Questionnaire-Urinary Incontinence Short Form before pregnancy, during early, mid- and late pregnancy, and at five visits during the first year postpartum. Data were analyzed using univariate/multivariate generalized estimating equation (GEE) logistic regression analyses.

RESULTS

The prevalence rates of stress UI during late pregnancy (42.5%) and urge UI at 3-5 days postpartum (10.4%) were the highest throughout pregnancy and the first year postpartum. After adjusting for covariates, gestational age increased the risks of stress UI (p < 0.001) and urge UI (p = 0.003); stress UI during pre-pregnancy, number of previous vaginal deliveries and concurrent high body mass index (BMI) increased stress UI (all p < 0.05); urge UI during pre-pregnancy and full-time work increased urge UI (both p < 0.05) during pregnancy. During the postpartum period, vaginal delivery increased stress UI (p < 0.001) and urge UI (p = 0.041); stress UI during pre-pregnancy and pregnancy, women aged ≥ 30 years and vacuum extraction/forceps delivery increased stress UI (all p < 0.05). Urge UI during early, mid- and late pregnancy increased stress UI (all p < 0.05).

CONCLUSIONS

Gestational age increased stress and urge UI, while previous vaginal deliveries and high BMI increased stress UI; full-time work increased urge UI during pregnancy. Vaginal delivery increased both UIs, and vacuum/forceps delivery and maternal age increased stress UI during postpartum.

Overactive Bladder in Frail Older Adults

Overactive bladder (OAB) and frailty are multidimensional syndromes, and the prevalence of both increases with age. Little evidence exists for a direct association between OAB and frailty, but urinary urgency may well be a precursor of frailty in older people. Frail older adults are no less deserving of treatment than fit older adults, and lifestyle, behavioral, and pharmacological interventions remain the primary options for treatment, with some evidence for efficacy. Data on onabotulinumtoxinA therapy or percutaneous tibial nerve stimulation in frail older adults are sparse. Frail older adults are often excluded from drug trials, but evidence is accumulating that antimuscarinics and, to a lesser extent, beta-adrenergic agonists are safe, well-tolerated, and effective in older adults. Cognitive impairment associated with frailty should not be used as justification for avoiding the use of antimuscarinics. More studies are required to better understand the association between OAB and frailty, as both are associated with poor outcomes and may be amenable to intervention. Drug trials for OAB treatments should be encouraged to include frail older adults, as this population is highly affected yet often excluded.

Urinary incontinence associated with anxiety and depression: the impact of psychotropic drugs in a cross-sectional study from the Norwegian HUNT study

BACKGROUND

Anxiety and depression are in both cross-sectional and longitudinal studies associated with urinary incontinence (UI) in women, strongest for the urgency component of UI. The role of psychotropic drugs in this association, especially antidepressants, has been questioned, but not clarified. The present study aimed to explore the associations between UI and anxiety/depression and the possible impact of psychotropic drugs on these associations.

METHODS

We conducted a cross-sectional, population-based study with questionnaire data from 21,803 women ≥20 years in the Norwegian Nord-Trøndelag Health Study merged with the Norwegian Prescription Database, which contains information on all dispensed prescriptions. We used multivariate logistic regression to investigate the association between UI (any UI, and by type and severity) and anxiety/depression (by different score on Hospital anxiety and depression scale), and the influence of psychotropic drugs on this association (by different volume of drug use).

RESULTS

Compared with normal anxiety- and depression score, having moderate/severe anxiety or depression (HADS≥11) increased the prevalence of UI from 27.6 to 37.8% (OR 1.59 (1.40-1.81), p < 0.001) for anxiety and from 28.0 to 43.7% (OR 1.79 (1.46-2.21), p < 0.001) for depression. According to type of UI, mixed UI was most strongly associated with a high HADS-score with an odds ratio 1.84 (1.65-2.05) for anxiety and 1.85 (1.61-2.13) for depression. Compared to no UI, severe UI was associated with depression with odds ratios of 2.04 (1.74-2.40), compared with no UI. Psychotropic drug use did not influence the associations between UI and anxiety/depression. We found high prevalence of UI among users of various psychotropic drugs. After adjustments, only antidepressants were associated with UI, with OR 1.36 (1.08-1.71) for high defined daily dose of the drug. Anxiolytics were associated with less UI with OR 0.64 (0.45-0.91) after adjustments for anxiety.

CONCLUSION

This study showed that anxiety, depression and use of antidepressants are associated factors with UI, strongest for urgency and mixed type of UI, with increasing ORs by increasing severity of the conditions and increased daily dose of the medication. Use of antidepressants did not influence the associations between UI and anxiety/depression.

The acupuncture-related therapy for post-stroke urinary incontinence: A protocol for systematic review and network meta-analysis

BACKGROUND

With the rising incidences stroke, the Post-Stroke Urinary Incontinence (PSUI) has become one of the common clinical sequelae. PSUI not only lowers the quality of life of patients, but also impacts tremendously to mental health. As a treasure of Chinese medicine, acupuncture and its related therapies have been widely accepted in clinical treatment of PSUI. Recently, there have been many clinical studies on the treatment of PSUI with acupuncture and related therapies, but the best way to treat PSUI is controversial. Therefore, the purpose of this paper is to provide an optimal ranking regarding acupuncture and its related therapies for PSUI.

METHODS

The five domestic and foreign databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database will be systematically searched. The time range of the literature search is from the date of establishment to August 31, 2020. The main evaluation outcome was the number of patients after treatment, and the frequency of urinary incontinence. The secondary evaluation outcome was International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), Barthel Activities of Daily Living Index (Barthel ADL Index) and the incidence rate of adverse events. The methodological quality of the article will evaluated by Cochrane Collaboration's Tool and the quality of evidence will evaluated through Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument. The Network Meta-Analysis (NMA) will be completed using Stata statistical software.

RESULTS

The final results of this study will be published in a peer-reviewed journal.

CONCLUSION

This network meta-analysis will compare the efficacy and safety of different acupuncture therapies in the treatment of PSUI and summarize the best treatment options, which will help patients and doctors to choose effective acupuncture methods in time.

Correlation of urinary incontinence with depression severity of patients treated for depression

Introduction

Urinary incontinence (UI) is a major public health issue because of the high number of individuals affected, its adverse effects on job-related functioning, and the decline in quality of life. The association between UI and symptoms of depression has been evaluated extensively for the general population. However, relationships between UI and depression have not been adequately assessed for specific patient groups. Thus, we investigated the association between UI and depression severity in patients treated for depression.

Material and methods

This study was a single-center, prospective, cross-sectional inquiry. We analyzed questionnaire data on UI and depression from depressed patients treated in our Department of Adult Psychiatry. Patients completed the International Consultation on Incontinence Questionnaire Short Form and General Health Questionnaire whereas psychiatrists administered the Hamilton Rating Scale for Depression.

Results

One hundred two patients were enrolled in the study. Most patients had mild depression. Patients who were incontinent mostly reported moderate UI and UI was statistically more prevalent in women than in men. Further, with the General Health Questionnaire, depression severity in women was significantly associated with the severity of UI. We did not observe correlation between depression severity analyzed with the Hamilton Rating Scale for Depression and UI.

Conclusions

In the cohort of patients treated for depression, UI affected more women than men. In wo- men, UI was associated with the severity of depression. Because UI and depression may coexist and share the symptom burden, particularly in women, clinicians should be aware of the interconnection between these two conditions.

Should we routinely assess psychological morbidities in idiopathic lower urinary tract dysfunction: ICI-RS 2019?

AIMS

Psychological morbidities play a major role in idiopathic lower urinary tract dysfunction (iLUTD). The aim of the Think Tank (TT) was to discuss the relevance of psychological morbidities in idiopathic LUTD over the life span, including overactive bladder (OAB) or dysfunctional voiding (DV) and methods of assessment.

METHODS

The paper is based on a selective review of the literature and in-depth discussions, leading to research recommendations regarding the assessment of psychological morbidities in iLUTD on children and adults held during the TT of the International Consultation on Incontinence Research Society in 2019.

RESULTS

Psychological comorbidities affect the health behaviors and treatment outcomes in patients with iLUTD. Both clinically relevant comorbid mental disorders, as well as subclinical psychological symptoms have a major impact and negatively influence incontinence treatment. Research is needed to elucidate mechanisms underlying iLUTD and psychological comorbidities. Clinical studies are needed to determine how perception generation and cognition impacts on the relationship of urinary perceptions, symptoms, and objective urodynamic function. Due to high psychological comorbidity rates, screening with validated, generic questionnaires for emotional and behavioral disorders in children with nocturnal enuresis, daytime urinary incontinence, and fecal incontinence is recommended. Brief screening is recommended for all adults with iLUTD, especially with OAB and DV, who are refractory to treatment.

CONCLUSIONS

Due to the high rate and relevance in clinical practice, screening for psychological comorbidities is recommended for all age groups. The research recommendations of this TT may be followed to improve the assessment of psychological morbidities in iLUTD.

Urinary incontinence in female university students

INTRODUCTION AND HYPOTHESIS

We aimed to determine the prevalence of urinary incontinence (UI) in nulliparous female university students and to provide an overview of risk factors associated with urinary continence.

METHODS

A total of 1,397 female university students aged 18-28 years were enrolled into this cross-sectional questionnaire study. The self-administered questionnaires, the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), Overactive Bladder V8 (OAB-V8), demographics, and general characteristics were recorded. The frequency, type, and severity of urinary incontinence and related factors were evaluated.

RESULTS

The mean age of the students was 20.27 ± 1.69 years. The prevalence of UI in female university students was 18.4% (n = 258). ICIQ-SF total score was 0.85 ± 2.11 (0-14). OAB-V8 total score was 5.97 ± 5.35 (0-40) and 27.0% of participants had scores of ≥8. Elevated BMI, childhood enuresis, constipation, exercising, positive family history for UI, accommodation in a dormitory, and holding urine at school are risk factors associated with UI in female university students.

CONCLUSION

We demonstrated that UI is a common condition among female university students. The identification of the associated risk factors will help to further raise the knowledge and awareness of the problem, and preventive strategies may be proposed to young women to improve the quality of life and psychological well-being.

Enhancing behavioral treatment for women with pelvic floor disorders: Study protocol for a pilot randomized controlled trial

Approximately one in four American women report bothersome urinary symptoms (e.g., urgency, frequency), which greatly impact quality of life, including mental health. Bidirectional relationships have been found between urinary symptoms and anxiety, such that urinary symptoms worsen emotional distress (i.e., anxiety and depression), and in turn anxiety can exacerbate these symptoms. Current methods to treat urinary symptoms, such as physical therapy and medications, do not address their emotional impact. As such, our multidisciplinary team is conducting a randomized control trial (RCT) of cognitive-behavior therapy (CBT) using the Unified Protocol (UP) versus supportive therapy in the context of integrated behavioral treatment in the urogynecology context. Women with bothersome urinary symptoms and anxiety are recruited from the Northwestern Medicine Integrated Pelvic Health Program (IPHP) -a transdisciplinary clinic including urogynecologists, urologists, colorectal surgeons, nurses, and physical therapists- and Northwestern Medicine Urology. Participants are randomized to one of two interventions: UP or supportive therapy. All participants attend therapy once per week for 12 weeks. Assessments of urinary symptoms, anxiety, and other indicators of psychological and physical functioning are completed at baseline, mid-treatment, post-treatment, and at 3- and 6-month follow-ups using patient-reported outcomes. The study has been preregistered on clinicaltrails.gov (ID: NCT03623880) and is currently ongoing.

Are psychological comorbidities important in the aetiology of lower urinary tract dysfunction-ICI-RS 2018?

AIMS

To review studies on the comorbid psychological symptoms and disorders in patients with lower urinary tract disorders (LUTD) over the life-span, to analyse how they contribute toward the aetiology of LUTD and to discuss optimal service implementation.

MATERIALS AND METHODS

A review of relevant literature was conducted and presented during the ICI-RS meeting in 2018. Open questions and future directions were discussed.

RESULTS

On the basis of current research, there is overwhelming evidence in all age groups that psychological comorbidities are more common in patients with LUTD. Vice versa, patients with psychiatric disorders have higher rates of LUTD. The types of LUTDs and psychiatric disorders are heterogeneous. Complex aetiological models best explain specific associations of comorbidity. Irrespective of aetiology, it is advisable to address both urological and psychological issues in patients of all age groups with LUTD.

CONCLUSIONS

Psychological symptoms and disorders play a decisive role in the development of LUTD in all age groups and need to be considered in the assessment and treatment of LUTD.

A systematic review and network meta-analysis comparing treatments for faecal incontinence

BACKGROUND

Although numerous treatments exist for fecal incontinence (FI), no consensus exists on the best treatment strategy. The aim was to review the literature and to compare the clinical outcomes and effectiveness of treatments available for FI.

MATERIALS AND METHOD

A systematic literature review was performed, from inception to May 2018, of the following databases: MEDLINE, EMBASE, Science Citation Index Expanded, Cochrane Library. The search terms used were "faecal incontinence" and "treatment". Only randomized controlled trials (RCTs) comparing treatments for FI were considered. A Bayesian network meta-analysis was performed using the Markov chain Monte Carlo method.

RESULT

Forty-seven RCTs were included comparing 37 treatments and reporting on 3748 participants. No treatment ranked best or worst with high probability for any outcome of interest. No significant difference was identified between treatments for frequency of FI per week, or in changing the resting pressure, maximum resting pressure, squeeze pressure, and maximum squeeze pressure. Radiofrequency resulted in more adverse events compared to placebo. Sacral nerve stimulation (SNS) and zinc-aluminium improved the fecal incontinence quality of life questionnaire (FIQL) lifestyle, coping, and embarrassment domains compared to placebo. Transcutaneous posterior tibial nerve stimulation (TPTNS) improved the FIQL embarrassment domain compared to placebo. Autologous myoblasts and zinc-aluminium improved the FIQL depression domain compared to placebo. SNS, artificial bowel sphincter (ABS), and zinc-aluminium significantly improved incontinence scores compared to placebo. Injection of non-animal stabilized hyaluronic acid/dextranomer (NASHA/Dx) resulted in more patients with ≥50% reduction in FI episodes compared to placebo.

CONCLUSION

SNS, ABS, TPTNS, NASHA/Dx, zinc-aluminium, and autologous myoblasts resulted in isolated improvements in specific outcomes of interest. No difference was identified in incontinence episodes, no treatment ranked best persistently or persistently improved outcomes, and many included treatments did not significantly benefit patients compared to placebo. Large multicentre RCTs with long-term follow-up and standardized inclusion criteria and outcome measures are needed.

The Incontinence Praying Ability and the Incontinence Quality of Life Questionnaires for Muslim Women: A Confirmatory Study of the Malay Language Versions

BACKGROUND

The aim of the present study was to determine the validity and reliability of the Malay versions of the Incontinence Praying Ability (I-PA) and the Incontinence Quality of Life (I-QoL) questionnaires among childbearing-aged Muslim women.

METHODS

This cross-sectional study included 338 childbearing-aged Muslim women (mean age: 31.1 years; SD = 5.57) who attended clinics at Hospital Universiti Sains Malaysia. Confirmatory factor analysis was conducted to determine the construct validity of the Malay versions of the I-PA and the I-QoL, while composite reliability was used to examine their internal consistency reliability.

RESULTS

The hypothesised models of the I-PA and the I-QoL consisted of 10 items with one latent variable and 22 items with three latent variables, respectively. The hypothesised models of the I-PA and the I-QoL did not have good fit. Modifications included co-varying the residual terms for items within the subscales, which resulted in improved fit indices for the I-PA (CFI = 0.976 TLI = 0.961, RMSEA = 0.068) and the I-QoL (CFI = 0.948, TLI = 0.938, RMSEA = 0.063). The composite reliability of the I-PA was 0.93, and the I-QoL ranged from 0.91 to 0.94.

CONCLUSION

The Malay versions of the I-PA and I-QoL were considered to be valid, reliable questionnaires measuring incontinence QoL among Muslim women of childbearing age.

Direct and Indirect Effects of Personality Traits on Psychological Distress in Women With Pelvic Floor Disorders

OBJECTIVES

The diagnosis and treatment of pelvic floor disorders may involve subjective self-report symptom measures that may be related to personality traits. We aimed to construct a model that integrates pelvic floor disorders, personality variables (optimism and neuroticism), psychological distress, and related demographic variables.

METHODS

In a cross-sectional study, conducted between August 2014 and June 2015, 155 women following an intake to an urogynecology outpatient clinic of a tertiary health center completed personality questionnaires of optimism and neuroticism (Life Orientation Test-Revised, 10-item Big Five Inventory), pelvic floor symptoms (Pelvic Floor Distress Inventory Short Form), psychological distress (18-item Brief Symptom Inventory), and a demographic questionnaire.

RESULTS

A path analysis mediation model showed that patients who had more pelvic floor symptoms felt more psychological distress and that psychological distress increased as the level of neuroticism increased. As for optimism, the correlation to pelvic floor symptoms was nearly significant. Optimism and neuroticism had indirect effects on psychological distress through pelvic floor symptoms in women with urinary incontinence and pelvic organ prolapse. Neuroticism had a direct effect on psychological distress in these women as well.

CONCLUSIONS

Our suggested statistical path analysis model supports the important role of personality traits in pelvic floor disorder self-reports and the effect of these traits on psychological distress. Therefore, the optimal treatment for pelvic floor symptoms should include psychological interventions in addition to traditional medical or surgical therapy in hope of reducing psychology distress associated with urinary incontinence and pelvic organ prolapse.

Is there "brain OAB" and how can we recognize it? International Consultation on Incontinence-Research Society (ICI-RS) 2017

AIMS

In light of mounting evidence supporting the association of brain regions with the control of urine storage and voiding, the high placebo effect in OAB studies as well as certain anecdotal observations from clinical practice with OAB patients, the role of the brain in OAB was explored.

METHODS

At the ICI-RS 2017 meeting, a panel of Functional Urologists and Basic Scientists presented literature data generating a proposal to discuss whether there is "brain OAB" and how we could recognize it.

RESULTS

Existing data point toward organic brain causes of OAB, in particular concerning white matter disease (WMD) and aging, but with currently speculative mechanisms. Imaging techniques have revealed connectivity changes between brain regions which may explain brain-peripheral interactions in OAB patients, further to acknowledged structural and functional changes in the central nervous system (CNS). Furthermore, psychological disorders like stress and depression have been identified as causes of OAB, with animal and human studies proposing a neurochemical and neuroendocrine pathophysiological basis, involving either the serotoninergic system or the hypothalamic-pituitary-adrenal axis. Finally, childhood data suggest that OAB could be a developmental disorder involving the CNS, although childhood OAB could be a different condition than that of adults in many children.

CONCLUSIONS

Future research should aim to identify the pathogenesis of WMD and the aging processes affecting the brain and the bladder, with possible benefits in prevention strategies, as well as connectivity disorders within the CNS, the pathophysiology of OAB in childhood and the neurochemical pathways connecting affective disorders with OAB.

PACAP/Receptor System in Urinary Bladder Dysfunction and Pelvic Pain Following Urinary Bladder Inflammation or Stress

Complex organization of CNS and PNS pathways is necessary for the coordinated and reciprocal functions of the urinary bladder, urethra and urethral sphincters. Injury, inflammation, psychogenic stress or diseases that affect these nerve pathways and target organs can produce lower urinary tract (LUT) dysfunction. Numerous neuropeptide/receptor systems are expressed in the neural pathways of the LUT and non-neural components of the LUT (e.g., urothelium) also express peptides. One such neuropeptide receptor system, pituitary adenylate cyclase-activating polypeptide (PACAP; Adcyap1) and its cognate receptor, PAC1 (Adcyap1r1), have tissue-specific distributions in the LUT. Mice with a genetic deletion of PACAP exhibit bladder dysfunction and altered somatic sensation. PACAP and associated receptors are expressed in the LUT and exhibit neuroplastic changes with neural injury, inflammation, and diseases of the LUT as well as psychogenic stress. Blockade of the PACAP/PAC1 receptor system reduces voiding frequency in preclinical animal models and transgenic mouse models that mirror some clinical symptoms of bladder dysfunction. A change in the balance of the expression and resulting function of the PACAP/receptor system in CNS and PNS bladder reflex pathways may underlie LUT dysfunction including symptoms of urinary urgency, increased voiding frequency, and visceral pain. The PACAP/receptor system in micturition pathways may represent a potential target for therapeutic intervention to reduce LUT dysfunction.

The prevalence of urinary incontinence in nulliparous adolescent and middle-aged women and the associated risk factors: A systematic review

Urinary incontinence (UI) has been defined as the complaint of involuntary loss of urine. There is a general belief that UI is experienced almost exclusively by the elderly and women who have given birth. However, epidemiological studies report that young women who are nulliparous also experience UI. The aim of this study was to systematically review studies investigating the prevalence of UI in nulliparous adolescent and middle-aged women and to provide an overview of risk factors associated with UI. The electronic databases PubMed, EMBASE, CINAHL, and Cochrane Library were systematically searched for eligible studies. Inclusion and exclusion criteria were defined a priori. The selected studies were reviewed and data extraction was carried out by the reviewers. Two independent researchers assessed the quality of the included studies. Eighteen studies were included in this systematic review. UI prevalence estimates varied from 1% to 42.2%. Among the women with UI of any type, 12.5% to 79% had stress urinary incontinence. BMI, childhood enuresis, and high-impact exercising were found to be the main associated risk factors. Understanding the effect of the risk factors on the pelvic floor will enable us to implement preventive strategies and advise appropriately on the prevention of UI.

Longitudinal associations between mental health conditions and overactive bladder in women veterans

BACKGROUND

One in 5 recently deployed US women veterans report overactive bladder symptoms. Mental health conditions such as depression and anxiety commonly co-occur in women with overactive bladder, but temporal relationships between these outcomes have not been well studied, and the mechanism behind this association is unknown. The Women Veterans Urinary Health Study, a nationwide longitudinal study in recently deployed women veterans, was designed to better understand relationships between overactive bladder and mental health conditions.

OBJECTIVE

We sought to estimate the 1-year incidence and remission of overactive bladder and to identify the impact of depression, anxiety, posttraumatic stress disorder, and prior sexual assault on 1-year overactive bladder incidence and remission rates.

STUDY DESIGN

Participants of this 1-year prospective cohort study were female veterans separated from military service who had returned from Iraq or Afghanistan deployment within the previous 2 years. Eligible women were identified through the Defense Manpower Data Center and recruited by mail and telephone. Telephone screening confirmed participants were ambulatory, community-dwelling veterans and excluded those with urinary tract fistula, congenital abnormality, or cancer; pelvic radiation; spinal cord injury; multiple sclerosis; Parkinson disease; stroke; or current/recent pregnancy. Data collection included computer-assisted telephone interviews performed at enrollment and 1 year later. The interview assessed demographic and military service characteristics; urinary symptoms and treatment; depression, anxiety, and posttraumatic stress disorder symptoms and treatment; and a lifetime history of sexual assault. Overactive bladder was identified if at least moderately bothersome urgency urinary incontinence and/or urinary frequency symptoms were reported on Urogenital Distress Inventory items. Exposures included depression, anxiety, posttraumatic stress disorder, and lifetime sexual assault, assessed at baseline using validated questionnaires (including the Patient Health Questionnaire and Posttraumatic Stress Disorder Checklist). Associations between exposures and overactive bladder incidence and remission were estimated using propensity score adjusted logistic regression models.

RESULTS

In all, 1107 (88.0%) of 1258 eligible participants completed 1-year interviews. Median age was 29 (range 20-67) years and 53% were nulliparous. Overactive bladder was identified at baseline in 242 (22%), and 102 (9.2%), 218 (19.7%), 188 (17.0%), and 287 (25.9%) met criteria for baseline depression, anxiety, posttraumatic stress disorder, and lifetime sexual assault, respectively. At 1 year, overactive bladder incidence was 10.5% (95% confidence interval, 8.6-12.8%), and remission of overactive bladder was 36.9% (95% confidence interval, 30.8-43.4%). New overactive bladder occurred more often in women with baseline anxiety (21% vs 9%), posttraumatic stress disorder (19% vs 9%) and lifetime sexual assault (16% vs 9%) (all: P < .01). After adjustment, anxiety (odds ratio, 2.4; 95% confidence interval, 1.4-4.1) and lifetime sexual assault (odds ratio, 1.7; 95% confidence interval, 1.0-2.8) predicted 1-year incident overactive bladder. Overactive bladder remission occurred less often in those with baseline depression (19% vs 41%, P < .01) and anxiety (29% vs 42%, P = .03). After adjustment, depression decreased 1-year overactive bladder remission risk (odds ratio, 0.37; 95% confidence interval, 0.16-0.83). Overactive bladder treatment was uncommon and not associated with remission.

CONCLUSION

Anxiety, depression, and prior sexual assault-common postdeployment problems for women veterans-influence the natural history of overactive bladder. Providers should screen for mental health conditions and sexual assault in women with newly diagnosed or persistent overactive bladder.

The bidirectional relationship between anxiety, depression, and lower urinary track symptoms: A nationwide population-based cohort study

BACKGROUND

Evidence has shown a positive correlation between lower urinary tract symptoms (LUTS) and anxiety/depression, but the direction and strength of the association are still unclear. We aimed to test the bidirectional association between LUTS and anxiety/depression using a longitudinal population database.

METHODS

Using claims data obtained from the Taiwan National Health Insurance Research Database, 17,489 patients with LUTS and 34,978 non-LUTS matched controls (cohort 1); and 45,707 patients with anxiety, 19,306 patients with depression, 91,414 non-anxiety, and 38,720 non-depression matched controls (cohort 2) were enrolled between 1999 and 2008. All subjects were followed at least three years or until the date of death or the end of 2011 to estimate the risk of developing anxiety/depression (cohort 1) or LUTS (cohort 2).

RESULTS

After controlling for age, gender, and medical comorbidities, LUTS patients were 2.12 (95%CI: 1.95-2.30) and 2.03 (95%CI: 1.76-2.33) times more likely to develop anxiety and depression, respectively. After controlling for age, gender, and medical comorbidities, patients with anxiety and depression were 2.01 (95%CI: 1.88-2.14) and 2.37 (95%CI: 2.13-2.65) times more likely to develop LUTS, respectively.

LIMITATIONS

The incidence of anxiety, depression, and LUTS may be under-estimated because only healthcare-seeking subjects were enrolled in our study.

CONCLUSIONS

Our findings suggested a bidirectional relationship between administrated anxiety/depression and LUTS in the cohorts. Further studies are warranted to clarify the underlying mechanisms.

Mediating Effect of Social Participation on the Relationship between Incontinence and Depressive Symptoms in Older Chinese Women

Urinary and fecal incontinence affect older women's social participation and mental health. This study examined the relationship between incontinence severity and depressive symptoms, focusing on the mediating effect of social participation, based on secondary analysis of structured interview data collected in December 2010 from 467 women age 60 and over in mainland China. Incontinence was significantly and positively associated with depressive symptoms but negatively associated with social participation. Social participation was significantly and negatively associated with depressive symptoms and fully mediated the relationship between incontinence and depressive symptoms. These findings can inform mental health interventions for incontinent older women, including preventing and responding to depressive symptoms by promoting social participation.

Severe depression and anxiety in women with overactive bladder

AIM

Depression and anxiety are prevalent psychiatric conditions and are associated with overactive bladder. The objective of this study was to determine prevalence and severity of anxiety and depression associated with overactive bladder (OAB) in women.

METHODS

274 women with clinical diagnosis of OAB were recruited from 2012 to 2015. They were submitted to the International Consultation on Incontinence Questionnaire-Overactive Bladder (ICIQ-OAB), the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI).

RESULTS

Severe or moderate depression was present in 59.8% of women and severe or moderate anxiety was identified in 62.4%. Higher scores of depression and anxiety were associated with higher scores of ICIQ-OAB (P = 0.0031 and 0.0049). Women with severe depression had higher nocturia score than those with mild depression (P = 0.0046). Also, women with severe depression had higher urgency incontinence score than those with minimal depression (P = 0.0261). Patients with severe anxiety had higher nocturia score than those with minimal anxiety (P = 0.0118) and women with moderate anxiety had higher urgency incontinence score than with minimal anxiety (P = 0.0300).

CONCLUSIONS

Moderate or severe depression and anxiety are prevalent in women with OAB. There is a correlation between intensity of OAB symptoms with depression and anxiety. Anxiety and depression levels are mainly related with urgency incontinence and nocturia.

Evaluation of Overactive Bladder in Male Antidepressant Users: A Prospective Study

PURPOSE

In this study, we investigated overactive bladder (OAB) functions in male patients who used antidepressant drugs (ADs) that were previously examined in female patients, based on conflicting data in literature regarding the effects of AD on OAB and the differences between male and female urinary system physiologies (anatomical and hormonal).

METHODS

The study included 202 male patients (a control group of 90 healthy subjects, and an experimental group of 112 patients taking ADs for different disorders). All the patients completed the overactive bladder-validated 8 (OAB-V8) questionnaire, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and the Beck Depression Inventory (BDS).

RESULTS

The OAB-V8, ICIQ-SF, and BDS scores for the antidepressant users were significantly higher than those of the control group. The highest prevalence of OAB symptoms was observed in patients taking venlafaxine (68.2%), and the lowest prevalence was in patients taking sertraline (28.0%). Moreover, the frequency of OAB between the antidepressant groups was statistically significant. The univariate logistic regression analyses showed a significant relationship between the presence of OAB, antidepressant usage, BDS score, and the age of a patient. In the multivariate logistic regression analyses, the association between the presence of OAB and antidepressant usage was statistically significant.

CONCLUSIONS

The present study showed that the incidence of OAB and the severity of OAB symptoms increased in males using antidepressants for various disorders. This may have been due to unique pharmacological effects, on a molecular or individual level, of serotonin-norepinephrine reuptake inhibitors.

The impact of genital self-image on sexual function in women with pelvic floor disorders

OBJECTIVE

There is conflicting evidence regarding the impact of urinary incontinence and pelvic organ prolapse on overall sexual function. However, psychological variables thought to be associated with sexual function, have not been fully explored. We assessed the sexual functioning of women with pelvic floor disorders while measuring for psychological factors such as distress and genital self-image.

STUDY DESIGN

In a cross-sectional study, 155 women in an urogynecology outpatient clinic of a tertiary health center completed a demographic questionnaire, the Brief Symptom Index-18 (BSI-18), Pelvic Floor Distress Inventory-20 (PFDI-20), Genital Self-Image Scale-20 (GSIS-20) and the Female Sexual Function Index (FSFI).

RESULTS

Linear regression showed that when controlling for age and depression, GSIS significantly predicted FSFI total score (Beta=0.38, p<0.001) and the Desire subscale (Beta=0.55, p<0.001). Due to the low response rate in the GSIS and FSFI questionnaires, a preliminary analysis was conducted to characterize the responders. On univariate logistic regression, response to the GSIS was negatively correlated with age (OR=0.94, p=0.02) and being in a relationship (OR=2.3, p=0.016), yet the effect of being in a relationship was diminished in a multivariate model that included age.

CONCLUSION

The main variable associated with overall sexual function in women with pelvic floor disorders was low genital self-image. This variable is more important than self-reported symptoms, type of specific disorder or other demographic variables. Older women tended not to complete the scales concerning more intimate matters. We suggest that urogynecologists should inquire about genital self-image as well as sexual function in this population.

The relationship between depression and overactive bladder/urinary incontinence symptoms in the clinical OAB population

Background

To investigate the relationship between depression and overactive bladder (OAB)/urinary incontinence symptoms among the clinical OAB population.

Methods

Patients who were diagnosed with overactive bladder (OAB) and age-matched control subjects without OAB were enrolled. Depression symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS-D). OAB/incontinence symptoms were assessed using the validated questionnaires: ICIQ-UI, ICIQ-OAB, UDI-6, IIQ-7, and OAB-q.

Results

27.5 % of OAB patients in our study had depression (HADS ≥8), and 12 % of OAB patients had moderate to severe depression (HADS-D ≥11). OAB patients reported significantly higher HADS-D depression scores compared to age-matched controls (5.3 ± 3.9 versus 2.8 ± 3.9, p = 0.004). OAB patients with depression reported more severe incontinence symptoms (ICIQ-UI), greater bother and more impact on quality of life (UDI-6, IIQ-7) compared to OAB patients without depression (p = 0.001, 0.01, <0.001, respectively). However there were no differences in ICIQ-OAB and OAB-q. Among OAB patients, there were positive correlations between the severity of depression symptoms and OAB/incontinence symptoms (p-values <0.001 to 0.035).

Conclusions

27.5 % of OAB patients have depression. OAB patients with depression reported more severe urinary incontinence symptoms, greater bother and more impact on quality of life compared to those without depression. Future studies are needed to further examine the mechanistic links between depression and OAB/urinary incontinence.

Bladder ultrasonography for diagnosing detrusor overactivity: test accuracy study and economic evaluation

BACKGROUND

Urodynamics (UDS) has been considered the gold standard test for detrusor overactivity (DO) in women with an overactive bladder (OAB). Bladder ultrasonography to measure bladder wall thickness (BWT) is less invasive and has been proposed as an alternative test.

OBJECTIVES

To estimate the reliability, reproducibility, accuracy and acceptability of BWT in women with OAB, measured by ultrasonography, in the diagnosis of DO; to explore the role of UDS and its impact on treatment outcomes; and to conduct an economic evaluation of alternative care pathways.

DESIGN

A cross-sectional test accuracy study.

SETTING

22 UK hospitals.

PARTICIPANTS

687 women with OAB.

METHODS

BWT was measured using transvaginal ultrasonography, and DO was assessed using UDS, which was performed blind to ultrasonographic findings. Intraobserver and interobserver reproducibility were assessed by repeated measurements from scans in 37 and 57 women, respectively, and by repeated scans in 27 women. Sensitivity and specificity were computed at pre-specified thresholds. The smallest real differences detectable of BWT were estimated using one-way analysis of variance. The pain and acceptability of both tests were evaluated by a questionnaire. Patient symptoms were measured before testing and after 6 and 12 months using the International Consultation on Incontinence modular Questionnaire Overactive Bladder (short form) (ICIQ-OAB) questionnaire and a global impression of improvement elicited at 12 months. Interventions and patient outcomes were analysed according to urodynamic diagnoses and BWT measurements. A decision-analytic model compared the cost-effectiveness of care strategies using UDS, ultrasonography or clinical history, estimating the cost per woman successfully treated and the cost per quality-adjusted life-year (QALY).

RESULTS

BWT showed very low sensitivity and specificity at all pre-specified cut-off points, and there was no evidence of discrimination at any threshold (p = 0.25). Extensive sensitivity and subgroup analyses did not alter the interpretation of these findings. The smallest detectable difference in BWT was estimated to be 2 mm. Pain levels following both tests appeared relatively low. The proportion of women who found the test 'totally acceptable' was significantly higher with ultrasonography than UDS (81% vs. 56%; p < 0.001). Overall, subsequent treatment was highly associated with urodynamic diagnosis (p < 0.0001). There was no evidence that BWT had any relationship with the global impression of improvement responses at 20 months (p = 0.4). Bladder ultrasonography was more costly and less effective than the other strategies. The incremental cost-effectiveness ratio (ICER) of basing treatment on the primary clinical presentation compared with UDS was £491,500 per woman successfully treated and £60,200 per QALY. Performing a UDS in those women with a clinical history of mixed urinary incontinence had an ICER of £19,500 per woman successfully treated and £12,700 per QALY compared with the provision of urodynamic to all women. For DO cases detected, UDS was the most cost-effective strategy.

CONCLUSION

There was no evidence that BWT had any relationship with DO, regardless of the cut-off point, nor any relationship to symptoms as measured by the ICIQ-OAB. Bladder ultrasonography has no diagnostic or prognostic value as a test in this condition. Furthermore, despite its greater acceptability, BWT measurement was not sufficiently reliable or reproducible.
