Pelvic floor dysfunction distress is correlated with quality of life, but not with muscle function

Can pelvic floor muscle function before surgery determine the outcome of surgical treatment of stress urinary incontinence in women?

AIM

The study aimed to determine whether pelvic floor muscle (PFM) function before surgery may correlate with the success of surgical interventions for treating stress urinary incontinence (SUI). Our hypothesis was that addressing identified variables in preoperative rehabilitation could potentially improve surgical outcomes.

METHODS

This prospective observational study was conducted at a single center and enrolled women qualified to mid-urethral tape insertion for SUI between 2020 and 2022. Digital palpation and manometry (Peritron™ 9300 V) were used to evaluate PFM function. The following parameters were acquired: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), the area under the curve during a 10-second MVC, moreover the ability to perform correct PFM contraction, reflexive PFM contraction during cough and relaxation were assessed. All measurements were performed before the surgical treatment and during follow-up assessments at 1, 3, and 6 months postoperatively. The primary endpoint of the study was defined as objective cure, characterized by a negative cough stress test (CST), along with a subjective assessment based on the Urogenital Distress Inventory-6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7).

RESULTS

The study involved 57 eligible female participants, all of whom completed the 6-month follow-up. Objective cure was observed in 75.44% of cases, while subjective cure was reported in 33%. There was no association between PFM parameters and surgical outcomes.

CONCLUSION

The success of surgical treatment of SUI 6 months postsurgery is not related to preoperative pelvic floor muscle function.

Acute Effect of Transcranial Direct Current Stimulation in Pelvic Floor Muscle Function in Young Healthy Women: Initial Findings of a Randomized Controlled Trial

INTRODUCTION AND HYPOTHESIS

Transcranial direct current stimulation (tDCS) can enhance muscle function in healthy individuals. However, it is unknown if tDCS associated with pelvic floor muscle training (PFMT) can improve pelvic floor muscle function (PFMF) in healthy women. The aim of this study was to investigate the acute effect of a single session of tDCS in PFMF compared with sham-tDCS in healthy women.

METHODS

A double-blind, cross-over, randomized clinical trial was conducted with healthy, nulliparous and sexually active women. PFMF was assessed by bidigital palpation (PERFECT scale) and intravaginal pressure by a manometer (Peritron™). Participants randomly underwent two tDCS sessions (active and sham) 7 days apart. The electrode was positioned equal for both protocols, the anode electrode in the supplementary motor area (M1) and the cathode electrode in the right supraorbital frontal cortex (Fp2). The current was applied for 20 min at 2 mA in active stimulation and for 30 s in sham-tDCS. The tDCS applications were associated with verbal instructions to PFMT in a seated position. After each tDCS session PFMF was reevaluated.

RESULTS

Twenty young healthy women (aged 23.4 ± 1.7 years; body mass index 21.7 ± 2.2 kg/m2) were included. No difference was observed in power, endurance, and intravaginal pressure of PFMF (p > 0.05). The number of sustained contractions improved from 3.0 (2.0-3.5) to 4.0 (3.0-5.0) after active-tDCS (p = 0.0004) and was superior to sham-tDCS (p = 0.01).

CONCLUSION

The number of sustained contractions of PFM improved immediately after a single active-tDCS session, with a difference compared with the post-intervention result of sham-tDCS in healthy young women.

Validation of the Hungarian version of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ)

Objective

The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) is a self-administered, reliable and valid instrument which assess knowledge regarding urinary incontinence and pelvic organ prolapse. There is no validated Hungarian version of this questionnaire; therefore the aim of this study was to develop a reliable, valid and culturally sensitive Hungarian version of the PIKQ.

Study design

A cross-sectional study was conducted from March to October 2022 with a sample of 459 women. The PIKQ, which consists of the urinary incontinence and pelvic organ prolapse scales, was translated into Hungarian in accordance with international guidelines. The validity and reliability of the final version of the Hungarian PIKQ was evaluated using construct validity, comparison with known-groups, internal consistency and test-retest reliability.

Results

Regarding construct validity, all fit indices were found acceptable. Healthcare workers had significantly higher knowledge about urinary incontinence and pelvic organ prolapse (p < 0.001) compared to women who had not worked in a medical field. The Hungarian PIKQ had an adequate internal consistency with Cronbach alpha of 0.785 for the urinary incontinence scale and 0.826 for the pelvic organ prolapse scale. The correlation coeffcients between the test and retest was 0.931 for the urinary incontinence scale and 0.964 for the pelvic organ prolapse scale.

Conclusion

The Hungarian version of the PIKQ is a reliable and valid tool to measure the level of knowledge about urinary incontinence and pelvic organ prolapse among Hungarian speaking women.

Reliability and validity of the Brazilian version of the world health organization disability assessment schedule (WHODAS 2.0) questionnaire for women with urinary incontinence

PURPOSE

To analyze the reliability and validity of the WHODAS 2.0 instrument for women with urinary incontinence (UI).

METHODS

This is a methodological study with Brazilian women with complaints of urge, stress or mixed UI, over 18 years old, without cognitive disorders. The WHODAS 2.0 (36-item version) and the auxiliary instruments were applied through face-to-face and telephone interviews after 7-14 d. The psychometric properties evaluated were: Cronbach's alpha for internal consistency, intraclass correlation coefficient (ICC) for intra-rater test-retest, Spearman's correlation coefficient (rho) for construct validity of WHODAS 2.0 with auxiliary instruments; and ANOVA for discriminative validity with UI severity.

RESULTS

101 women with UI with a mean age of 50.71 ± 10.39 were included. WHODAS 2.0 showed good reliability in all domains and excellent reliability in the total score (>0.80). The intra-evaluator test-retest showed ICC values between 0.59 and 0.87 (p < 0.001). We observed a positive correlation between the WHODAS 2.0 domains and the instruments recommended by International Continence Society (ICS), with greater emphasis on moderate correlation with the Urinary Impact Questionnaire (IUQ-7) subscale (rho = 0.730 p < 0.001).

CONCLUSION

The WHODAS 2.0 instrument is a reliable and valid questionnaire for investigating the functioning and disability of women with UI.

Do pelvic floor muscle function parameters differ in women according to continence status? A systematic review

BACKGROUND

Current literature highlights the difficulty in identifying which pelvic floor muscle (PFM) functions are correlated with urinary incontinence (UI).

AIM

In this study, we compared parameters of PFM function (strength, endurance, tone, control, reaction, and/or coordination) according to continence status in women (presence or absence, type and/or severity of urinary incontinence).

EVIDENCE ACQUISITION

A systematic review was conducted following the 2020 PRISMA guidelines. Three databases (Pubmed, Web of Science, and LiSSa) were searched from inception to December 31, 2021. Assessment of risk of bias was performed using the Joanna Briggs Institute critical appraisal checklist.

EVIDENCE SYNTHESIS

The initial research yielded 4733 studies. Forty-two studies met the inclusion criteria, including 4015 participants. No statistical association was found between PFM function and the presence or absence of UI, the different type of UI or the different levels of severity of UI. The heterogeneity in methodologies and analyzes of the results only with the P-value are important limitations of this review.

CONCLUSION

It appears that muscle function is not always associated with presence or absence of UI. No association is found between PFM function and type or severity of UI. These results reinforce the need to carry out a bio-psycho-social evaluation of UI that does not only focus on PFM functions. As such, the results reported herein can be considered a resource for more specific research.

Protocol for a prospective longitudinal cohort study on the effects of non-surgical weight loss on pelvic floor dysfunction

INTRODUCTION

Recent studies have recommended non-surgical weight loss and pelvic floor muscle training as first-line treatment for obese patients with urinary incontinence. However, limited studies are detecting the effect of weight loss on other types of pelvic floor dysfunctions (PFDs), as well as on the quality of life (QoL) and the related influencing factors.

METHODS AND ANALYSIS

The "Weight Loss on Pelvic Floor Dysfunction"(WLPFD) observational study is a 6 months prospective, longitudinal real-world cohort study aiming to recruit 200 patients. Participants will be followed up three times during the study: at baseline, and at 2 and 6 months. The methodology involves recruitment and follow-up of participants, data collection through validated questionnaires, and statistical analysis to assess the impact of non-surgical weight loss on PFD and QoL.

ETHICS AND DISSEMINATION

This study has been reviewed and given a favourable ethical opinion by the Peking Union Medical College Hospital ethics committee (K4278). All results from the study will be submitted to international journals and international conferences.

Psychometric evaluation and cross-cultural adaptation of the Australian Pelvic Floor Questionnaire (APFQ-IR) in Iranian reproductive age women

Pelvic floor disorders (PFDs), as a silent alert, is one of the pervasive debilitating health concerns among women all over the world, such that in developed countries, one in four women, suffers from PFDs. Validity and reliability of the Australian Pelvic Floor Questionnaire (APFQ) has not been determined in Iran, so to determine APFQ's psychometric characteristics, we decided to conduct this study on women of reproductive age in Tabriz city, Iran. This methodological cross-sectional study was intended to determine the psychometric properties of the Persian version of the APFQ-IR in 5 steps including "translation process, content validity, face validity, construct validity (exploratory and confirmatory factor analyses and examination of ceiling and floor effects) and reliability" on 400 reproductive age women referring to health centers in Tabriz city, Iran, with cluster random sampling method in the period between May 2022 to September 2022. The translation process was done based on two approaches, Dual panel, and Beaton et al.'s five steps. Then, in order to evaluate content validity, face validity, and construct validity, 10 instrument and PFDs experts, 10 women from the target group investigated the instrument's items, and 400 eligible women completed the instrument. Finally, to determine the reliability, two internal consistency methods, (Cronbach's alpha and McDonald's omega) and test-retest method (ICC) were used. In the present study, content validity assessment of APFQ-IR, showed a good level of validity (CVR = 0.96, CVI = 0.94). To assess construct validity, exploratory factor analysis results on 36 items, led to the identification of 4 factors including bladder function, bowel function, prolapse symptom and sexual function, which explained 45.53% of the cumulative variance and indicated the sufficiency of the sample size (Kaiser-Meyer-Olkin = 0.750). Implementing confirmatory factor analysis, (RMSEA = 0.08, SRMR = 0.08, TLI = 0.90, CFI = 0.93, χ2/df = 3.52) confirmed the model fit indices. Finally the internal consistency and reliability was high for the entire instrument (Cronbach's alpha = 0.85; McDonald's omega (95% CI) = 0.85 (0.83-0.87) and Intraclass Correlation Coefficient (95% CI) = 0.88 (0.74-0.94)). The Persian version of the APFQ-IR, has a good validity and reliability and has acceptable psychometric properties, thus can be used both for research purposes and for clinical evaluation of pelvic floor disorders symptoms in health centers.

Characteristics Associated with Pelvic Floor Disorders among Female Canadian Armed Forces Members

OBJECTIVES

Urinary incontinence (UI) and pelvic organ prolapse (POP) are prevalent pelvic floor disorders (PFDs) among the female population. In the military environment, being a non-commissioned member (NCM), and physically demanding occupations are factors associated with higher PFD risk. This study seeks to characterize the profile of female Canadian Armed Forces (CAF) members reporting symptoms of UI and/or POP.

METHODS

Present CAF members (18-65 years) responded to an online survey. Only current members were included in the analysis. Symptoms of UI and POP were collected. Multivariate logistic regressions analyzed the relationships between PFD symptoms and associated characteristics.

RESULTS

765 active members responded to female-specific questions. The prevalence of self-reported POP and UI symptoms were 14.5% and 57.0%, respectively, with 10.6% of respondents reporting both. Advanced age (adjusted odds ratio [aOR]: 1.062, CI 1.038-1.087), a body mass index (BMI) categorized as obese (aOR: 1.909, [1.183-3.081]), parity ≥1 (e.g., aOR for 1: 2.420, [1.352-4.334]) and NCMs (aOR: 1.662, [1.144-2.414]) were factors associated with urine leakage. Parity of ≥2 (aOR: 2.351, [1.370-4.037]) compared to nulliparous and having a perception of a physically demanding job (aOR: 1.933, [1.186-3.148]) were associated with experiencing POP symptoms. Parity of ≥2 increased the odds of reporting both PFD symptoms (aOR: 5.709, [2.650-12.297]).

CONCLUSION

Parity was associated with greater odds of experiencing symptoms of UI and POP. Higher age, higher BMI, and being an NCM were associated with more symptoms of UI, and the perception of having a physically demanding role increased the likelihood of reporting POP symptoms.

Quality of life and its associated factors among women diagnosed with pelvic organ prolapse in Gynecology outpatient department Southern Nations, Nationalities, and Peoples region public referral hospitals, Ethiopia

BACKGROUND

Pelvic organ prolapse is an important public health issue that influences millions of women's lives; through limitations on physical, social, and sexual activities as well as psychological distress. However, there were no reports on the quality of life for women with pelvic organ prolapse in Ethiopia. Therefore this study amid to assess the magnitude of quality of life and its associated factors among women who diagnosed with pelvic organ prolapse in Gynecology outpatient departments in Southern Nations, Nationalities, and Peoples region public referral hospitals; Ethiopia.

METHOD

An institutional-based cross-sectional study was conducted in Southern Nations, Nationalities, and Peoples region of public referral hospitals from May 1-July 4, 2022 among 419 diagnosed women with pelvic organ prolapse. A validated tool was used to collect the data. The collected data were entered into Epidata version 3.1 and analyzed using the Statistical Package for Social Sciences. Bivariable and multivariable logistic regression was computed. The p-value of < 0.05 was used to declare the final statistical significance.

RESULT

A total of 409 women with pelvic organ prolapse were included in the study, giving a response rate of 97.6%. The overall poor quality of life was 57.5%. Regarding the quality of life domains; personal relationships (73.6%), were highly affected, and sleep/energy (24.2%) was the least affected domain. Stage III/IV prolapse (AOR = 2.52, 95% CI: 1.34, 4.74), menopause (AOR = 3.21, 95% CI 1.75, 5.97), unmarried women (widowed, divorced) (AOR = 2.81, 95% CI: 1.48, 5.32), and longer duration of prolapse (AOR = 5.8, 95% CI: 3.13, 10.81), were significantly associated with poor quality of life.

CONCLUSION

More than half of women with pelvic organ prolapse had a poor quality of life. Stage III/IV prolapse, longer duration of prolapse, menopause women, and unmarried women are statistically significant factors for the quality of life of women with Pelvic organ prolapse.

Inequality in healthcare-seeking behavior among women with pelvic organ prolapse: a systematic review and narrative synthesis

INTRODUCTION

Pelvic organ prolapse (POP) affects women's quality of life in various aspects. However, evidence on the healthcare-seeking behavior of women with POP is limited. Therefore, this review aimed to identify and synthesize the existing evidence on the healthcare-seeking behavior among women with POP.

METHODS

This systematic review and narrative synthesis of the literature on healthcare-seeking behavior among women with POP was conducted from 20 June to 07 July 2022. The electronic databases PubMed, African Journals Online, Cumulative Index to Nursing and Allied Health Literature, African Index Medicus and Directory of Open Access Journal, and Google Scholar were searched for relevant literature published from 1996 to April 2022. The retrieved evidence was synthesized using a narrative synthesis approach. The characteristics of included studies and the level of healthcare-seeking behavior were summarized in a table and texts. Error bar was used to show the variability across different studies.

RESULTS

A total of 966 articles were retrieved of which only eight studies with 23,501 women (2,683 women with pelvic organ prolapse) were included in the synthesis. The level of healthcare-seeking behavior ranges from 21.3% in Pakistan to 73.4% in California, USA. The studies were conducted in four different populations, used both secondary and primary data, and were conducted in six different countries. The error bar shows variation in healthcare-seeking behavior.

CONCLUSIONS

The level of health-care seeking behavior among women with POP is low in low-income countries. There is substantial variability in the characteristics of the reviewed studies. We recommend a large-scale and robust study which will help to better understand the healthcare-seeking behavior among women with POP.

The role of in-person focus groups in the management of urinary incontinence in women from a mixed-methods, randomized pilot study

PURPOSE

To assess the quantitative and qualitative components of in-person focus groups as a potential intervention for female patients with urinary incontinence.

METHODS

Women over the age of 18 seeking treatment for UI were randomized to standard care with focus group participation or to standard care alone. All participants completed validated questionnaires: MESA, UDI-6, OAB-SAT-q, PGI-S, PGI-I, SQoL-F, PHQ-9, IPAQ at the beginning and conclusion of the study. Questionnaires were analyzed with repeated measures of ANOVA models in an intention-to-treat manner. Three moderated focus group sessions were held and audio recorded. Recordings were transcribed and categorized by frequency into themes using grounded theory methodology.

RESULTS

A total of ten control and eight intervention participants agreed to participate. Seven women attended all three focus group sessions and were included in the final analysis. Transcripts from focus group sessions observed women identified most with (1) urinary incontinence (UI) as a chronic disease, (2) shame managing UI, and (3) social constraints of toileting. Participants self-reported appreciation of focus group participation and desire for on-going sessions. Analysis of the questionnaires did not demonstrate statistically significant differences.

CONCLUSION

Data ascertained from questionnaires were unable to demonstrate a meaningful effect in improved treatment outcomes for control and intervention participants. Grounded theory analysis of transcripts identified four primary themes: (1) appreciation of the focus group, (2) UI as a gendered issue, (3) lack of public awareness, and (4) history of negative provider interactions. All focus group participants self-reported interest in attending future focus group sessions.

Application of estrogen for the treatment of stress urinary incontinence in mice

BACKGROUND

Stress urinary incontinence (SUI) is a pervasive health tissue among women, which seriously affects the quality of life. The etiology of SUI is complex and diverse in women, with past studies having demonstrated that estrogen deficiency plays an important role in pelvic floor muscle atrophy and urethral degeneration. We comprehensively investigated the effects of estrogen in the treatment of SUI in female mice at cellular and animal levels.

METHODS

L929 fibroblasts mechanical injury model was established by four-point bending device, and SUI mouse model was established by vaginal dilation method commonly used to simulate labor injury. After estrogen treatment, the expressions of Collagen I, Collagen III, Elastin, TIMP-1, TIMP-2, MMP-2, and MMP-9 were detected, the leak point pressure (LPP) and abdominal leak point pressure (ALPP) of mice in each group were detected, and both the effect of estrogen on extracellular matrix remodeling of mouse urethra and anterior vaginal wall was observed from the histological level.

RESULTS

The results revealed that an appropriate amount of estrogen can promote the expression of Collagen I, Collagen III, Elastin, TIMP-1, and TIMP-2, decrease the expression of MMP-2 and MMP-9, and maintain the dynamic balance of MMPs/TIMPs at both cellular and animal levels. Meanwhile, we determined that estrogen can increase the LPP and ALPP values of SUI mice. The collagen fibers' content in the mice treated with estrogen was significantly greater than in the control group mice.

CONCLUSIONS

The estrogen may alleviate the symptoms of SUI by reconstituting ECM, thus laying a solid foundation for further exploration of estrogen therapy.

Three-year follow-up of a self-administered Australian pelvic floor questionnaire validated in Chinese pregnant and postpartum women

INTRODUCTION AND HYPOTHESIS

The aim of this study was to verify whether the Chinese version of the self-administered Australian Pelvic Floor Questionnaire (APFQ) can assess the changes in symptoms over a long time period (responsiveness) and to verify the reliability and validity of the questionnaire after 3 years of follow-up.

METHODS

The questionnaire was completed by 146 women using the WeChat platform after 3 years of follow-up. Reliability was assessed through internal consistency (Cronbach's alpha). Construct validity was evaluated by significantly distinguished differences in symptom scores between women who did and did not subjectively suffer bothersome symptoms. Responsiveness was evaluated in 146 women. The effect size (ES) and standardized response mean (SRM) were used to assess the degree of responsiveness.

RESULTS

Of the 146 women, all completed the questionnaire through the WeChat platform without missing any items. Reliability, Cronbach's alpha for the four domains and total APFQ were: bladder function 0.78, bowel function 0.71, pelvic organ prolapse 0.78, sexual function 0.68 and total APFQ 0.84. Concerning construct validity, the APFQ significantly distinguished the symptom scores between women who did and did not subjectively suffer from bothersome symptoms, and the score difference was 1.1-1.6 points, 1.2 points, 2.0-3.7 points and 1.4 points, respectively. For responsiveness, three domains showed slight (bowel domain) to moderate (bladder domain, sex domain) sensitivity to change. ES and SRM ranged from 0.21 to 0.75 and 0.16 to 0.60, respectively.

CONCLUSIONS

The Chinese version of the self-administered APFQ is reliable and valid and can monitor the changes in symptoms over time.
