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

Comparisons of approaches to pelvic floor muscle training for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training (PFMT) is a recommended treatment for female stress, urgency, and mixed urinary incontinence. Training varies in exercise type (pelvic floor muscles contracting with and without other muscles), dose, and delivery (e.g. amount and type of supervision).

OBJECTIVES

To assess the effects of alternative approaches (exercise type, dose, and delivery) to pelvic floor muscle training (PFMT) in the management of urinary incontinence (stress, urgency, and mixed) in women.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register (searched 27 September 2023; which contains CENTRAL, MEDLINE, ClinicalTrials.gov, and World Health Organization ICTRP), handsearched journals and conference proceedings, and reviewed reference lists of relevant articles.

SELECTION CRITERIA

Randomised, quasi-randomised, or cluster-randomised trials in female stress, urge, or mixed urinary incontinence where one trial arm included PFMT and another was an alternative approach to PFMT type, dose, or intervention delivery. We excluded studies with participants with neurological conditions or pregnant or recently postpartum.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for eligibility and methodological quality using the Cochrane RoB 1 tool. We extracted and cross-checked data and resolved disagreements by discussion. Data processing was as described in the Cochrane Handbook for Systematic Reviews of Interventions (Version 6). Synthesis was completed in intervention subgroups.

MAIN RESULTS

This is a review update. The analysis included 63 trials with 4920 women; the previous version included 21 trials with 1490 women. Samples sizes ranged from 11 to 362. Overall, study participants were mid-age (45 to 65 years) parous women with stress or stress-predominant mixed urinary incontinence (46 trials), who had no prior incontinence treatment or pelvic surgery, or appreciable pelvic floor dysfunction. Trials were conducted in countries around the world, mostly in middle- or high-income settings (53 trials). All trials had one or more arms using 'direct' PFMT, defined as repeated, isolated, voluntary pelvic floor muscle contractions. Trials were categorised as comparisons of exercise type (27 trials, 3 subgroups), dose (11 trials, 5 subgroups, 1 with no data), and delivery (25 trials, 5 subgroups). Incontinence quality of life data are reported here as the primary outcome. Adverse event data were summarised narratively. Comparison 1: exercise type Co-ordinated training (body movements with concurrent pelvic floor muscle contraction) versus direct PFMT Co-ordinated training may slightly improve quality of life (standardised mean difference (SMD) -0.22, 95% confidence interval (CI) -0.44 to -0.01; I2 = 81%; 8 trials, 356 women; low-certainty evidence). Indirect training (exercises that are not contractions of the pelvic floor muscles) versus direct PFMT Direct PFMT may moderately improve quality of life (SMD 0.70, 95% CI 0.38 to 1.02; I2 = 78%; 4 trials, 170 women; low-certainty evidence). Indirect training combined with direct PFMT versus direct PFMT Combining indirect training with direct PFMT may make little to no difference in quality of life (SMD -0.08, 95% CI -0.26 to 0.10; I2 = 33; 7 trials, 482 women; low-certainty evidence). Comparison 2: exercise dose PFMT with resistance device versus PFMT without resistance device PFMT without a resistance device may slightly improve incontinence quality of life, but the evidence is very uncertain (SMD 0.22, 95% CI -0.04 to 0.48; I2 = 32%; 3 trials, 227 women; very low-certainty evidence). Maximal pelvic floor muscle contractions versus submaximal pelvic floor muscle contractions No data reported. PFMT more days per week versus PFMT fewer days per week PFMT more days per week may greatly improve incontinence quality of life (SMD -1.60, 95% CI -2.15 to -1.05; 1 trial, 68 women; low-certainty evidence). PFMT in upright body positions versus PFMT when lying down No data reported. Comparison 3: exercise intervention delivery PFMT supervised in clinic versus PFMT at home Clinic supervision may slightly improve incontinence quality of life, but the evidence is very uncertain (SMD -0.30, 95% CI -0.65 to 0.05; I2 = 89%; 3 trials, 137 women; very low-certainty evidence). More clinician contact for PFMT supervision versus less clinician contact No usable data reported. Individual supervision of PFMT versus group supervision Individually supervised PFMT probably results in little to no difference in quality of life (SMD -0.18, 95% CI -0.35 to -0.01; I2 = 0%; 5 trials, 544 women; moderate-certainty evidence). PFMT supervised in clinic versus supervision using e-health (mobile app communication with clinicians) Clinic supervision may make little to no difference in incontinence quality of life, but the evidence is very uncertain (SMD -0.11, 95% CI -0.41 to 0.19; 1 trial, 173 women; very low-certainty evidence). PFMT instruction delivered via e-health versus written instruction E-health delivery may slightly improve quality of life (SMD -0.21, 95% CI -0.43 to 0.01; I2 = 25%; 3 studies, 318 women; low-certainty evidence). Adverse events Nine trials collected adverse event data; 66/1083 (6%) women had an adverse event. Almost all events were associated with use of an intravaginal or intrarectal training device. The adverse events were vaginal discharge, spotting, or discomfort. Limitations in the evidence Four main factors influenced our certainty in the evidence: 44 trials were at unclear or high risk of selection bias; data were sparse in some subgroups with few trials, trials that did not measure outcomes of interest, or did not report usable data; results were inconsistent; and many trials were small (imprecise).

AUTHORS' CONCLUSIONS

Although there is low- to moderate-certainty evidence that some approaches to PFMT are better than others, for some there was little or no difference. The 7th International Consultation on Incontinence recommends PFMT as first-line therapy for women with urinary incontinence. Direct PFMT (sets of repeated, isolated, voluntary pelvic floor muscle contractions) may result in a small improvement in incontinence quality of life compared to indirect training. In terms of improved quality of life, PFMT can be supervised individually or in a group because it probably makes little to no difference in achieving this outcome. Many comparisons had low- or very low-certainty evidence, often because there was only one trial or several small trials with methodological limitations. More, better designed and reported trials, directly comparing PFMT approaches are needed, especially trials investigating exercise dose.

Conservative treatments for women with stress urinary incontinence: a systematic review and network meta-analysis

Objective

This study aimed to compare the effectiveness of various conservative treatment strategies for women with stress urinary incontinence.

Methods

A comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library was conducted from their inception through March 2024, without restrictions on language or location. Randomized controlled trials (RCTs) comparing the efficacy of conservative treatments for stress urinary incontinence, using short-term pad test or the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) score as outcome measures, were included. We conducted a network meta-analysis using a random-effects model to compare the effectiveness of different conservative treatment strategies, employing prediction interval plots and league tables, and ranked them according to the surface under the cumulative ranking curve (SUCRA). The quality of the included studies was assessed following the Cochrane Handbook for Systematic Reviews of Interventions.

Results

A total of 31 RCTs involving 1,900 patients across 8 intervention categories were included in the analysis. SUCRA rankings indicated that electrical stimulation (SUCRA = 95.9%) was the most effective therapy for improving ICIQ-UI SF scores, followed by biofeedback electrical stimulation (SUCRA = 84.9%), radiofrequency (SUCRA = 77.5%), biofeedback (SUCRA = 57.8%), magnetic stimulation (SUCRA = 45.3%), pelvic floor muscle training (SUCRA = 38.4%), Er: YAG laser (SUCRA = 37.4%), and CO2 laser (SUCRA = 7.4%). In terms of reducing urine leakage, the treatments were ranked in descending order as follows: Er: YAG laser (SUCRA = 97.5%), biofeedback electrical stimulation (SUCRA = 83.4%), biofeedback (SUCRA = 67.0%), radiofrequency (SUCRA = 59.5%), electrical stimulation (SUCRA = 48.4%), pelvic floor muscle training (SUCRA = 43.0%), magnetic stimulation (SUCRA = 27.8%), and CO2 laser (SUCRA = 21.4%). Based on the clustered rankings of the two metrics, biofeedback electrical stimulation was identified as the most effective therapy for improving stress urinary incontinence.

Conclusion

Based on the combined analysis of two indicators, we found that biofeedback electrical stimulation may be the optimal therapy for the conservative management of stress urinary incontinence.

Pelvic floor rehabilitation in cancer survivorship: an umbrella review

PURPOSE

This umbrella review aimed to identify, critically appraise, and summarize current systematic reviews with meta-analyses on the role of pelvic floor rehabilitation in cancer survivorship.

METHODS

Four bibliographic databases were searched from inception to August 1, 2024. Two independent reviewers screened the titles and abstracts of 379 records and retrieved 24 full-text systematic reviews. Assessing the Methodological Quality of Systematic Reviews-2 was used for quality assessment. Qualitative syntheses were performed to compile the effects of pelvic floor rehabilitation on bladder function, bowel function, quality of life, and other outcomes. Measures of effect sizes of these outcomes in each meta-analysis were extracted and summarized.

RESULTS

Seventeen systematic reviews with meta-analyses published between 2012 and 2024 were included in this umbrella review, containing a total of 92 primary studies. For quality assessment, four studies were evaluated as moderate quality, five as low, and eight as critically low. Populations with prostate, colorectal, and gynecological cancer were studied. Effects of pelvic floor rehabilitation on bladder, bowel, sexual function, and quality of life were reported and synthesized.

CONCLUSIONS

Pelvic floor rehabilitation is an essential component of cancer survivorship, including following prostate, colorectal, and gynecological cancer surgery. Further high-quality primary studies with adequate sample sizes are needed to inform clinical practice and research endeavors.

IMPLICATIONS FOR CANCER SURVIVORS

This umbrella review highlights the therapeutic potential of pelvic floor rehabilitation, underscores the need for its broader implementation in survivorship care, and guides future research directions to optimize outcomes for cancer survivors.

Prevalence and Spatial Distribution Characteristics of Female Stress Urinary Incontinence in Mainland China

Background and objective

Stress urinary incontinence (SUI) in women is a common condition that affects middle-aged and elderly women. Currently, there are still many limitations in the epidemiological research on SUI. This study aims to address the gap in the prevalence of female SUI in mainland China and provide theoretical support for the prevention and treatment of SUI.

Methods

A comprehensive literature search was conducted on the prevalence of female SUI in mainland China, systematically searching Chinese and English databases including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, and Weipu Database as of April 1, 2024. Detailed criteria for screening and exclusion were established. The prevalence of SUI in the selected studies was synthesized using Stata MP (version 15) software, and a multisubgroup analysis, a sensitivity analysis, and publication bias detection of the prevalence of SUI were also performed using the software. Additionally, ArcGIS software (version 10.8) and Geoda software (version 1.2) were utilized to explore the geographical distribution characteristics of the prevalence of female SUI in mainland China.

Key findings and limitations

A total of 688 articles were screened, and finally 85 articles were included. The overall rate of female SUI in mainland China was 24.5% (95% confidence interval: 22.5-26.5%). The heterogeneity of the study is statistically significant (I2 = 99.0%, p < 0.001). Based on significant heterogeneity, a multisubgroup analysis was conducted. The results showed that the prevalence of SUI varies among different publication years, literature quality scores, investigators, study settings, sampling methods, provinces, regions, coastal or inland areas, and rural or urban areas. A spatial econometric analysis indicated that the incidence of SUI in the east-west distribution showed a downward trend, while in the north-south distribution, the incidence rate of SUI showed a trend of first increasing and then decreasing. Additionally, a spatial metrology analysis showed similar trends in the distribution of SUI incidence.

Conclusions and clinical implications

The high incidence rate of female SUI in mainland China and the regional differences observed indicate the need for further rigorous epidemiological investigation in the future.

Patient summary

Stress urinary incontinence (SUI) is common among middle-aged and elderly women. The high prevalence of SUI in mainland China and the differences across regions emphasize the need for conducting more robust epidemiological studies in the future.

Efficacy of a Therapeutic Pelvic Yoga Program Versus a Physical Conditioning Program on Urinary Incontinence in Women : A Randomized Trial

BACKGROUND

Pelvic floor yoga has been recommended as a complementary treatment strategy for urinary incontinence (UI) in women, but evidence of its efficacy is lacking.

OBJECTIVE

To evaluate the effects of a therapeutic pelvic floor yoga program versus a nonspecific physical conditioning program on UI in women.

DESIGN

Randomized trial. (ClinicalTrials.gov: NCT03672461).

SETTING

Three study sites in California, United States.

PARTICIPANTS

Ambulatory women aged 45 years or older reporting daily urgency-, stress-, or mixed-type UI.

INTERVENTION

Twelve-week program of twice-weekly group instruction and once-weekly self-directed practice of pelvic floor-specific Hatha yoga techniques (pelvic yoga) versus equivalent-time instruction and practice of general skeletal muscle stretching and strengthening exercises (physical conditioning).

MEASUREMENTS

Total and type-specific UI frequency assessed by 3-day voiding diaries.

RESULTS

Among the 240 randomly assigned women (age range, 45 to 90 years), mean baseline UI frequency was 3.4 episodes per day (SD, 2.2), including 1.9 urgency-type episodes per day (SD, 1.9) and 1.4 stress-type episodes per day (SD, 1.7). Over a 12-week time period, total UI frequency (primary outcome) decreased by an average of 2.3 episodes per day with pelvic yoga and 1.9 episodes per day with physical conditioning (between-group difference of -0.3 episodes per day [95% CI, -0.7 to 0.0]). Urgency-type UI frequency decreased by 1.2 episodes per day in the pelvic yoga group and 1.0 episode per day in the physical conditioning group (between-group difference of -0.3 episodes per day [CI, -0.5 to 0.0]). Reductions in stress-type UI frequency did not differ between groups (-0.1 episodes per day [CI, -0.3 to 0.3]).

LIMITATION

No comparison to no treatment or other clinical UI treatments; conversion to videoconference-based intervention instruction during the COVID-19 pandemic.

CONCLUSION

A 12-week pelvic yoga program was not superior to a general muscle stretching and strengthening program in reducing clinically important UI in midlife and older women with daily UI.

Effect of intra-vaginal electric stimulation on bladder compliance in stress urinary incontinence patients: the involvement of autonomic tone

Objective

In addition to the well-established advantage that strengthened pelvic musculature increases urethral resistance in stress urinary incontinence (SUI) patients, intra-vaginal electrical stimulation (iVES) has been shown in preclinical studies to improve bladder capacity via the pudendal-hypogastric mechanism. This study investigated whether iVES also benefits bladder storage in SUI patients by focusing on compliance, a viscoelastic parameter critically defining the bladder's storage function, in a clinical study. Moreover, the potential involvement of stimulation-induced neuromodulation in iVES-modified compliance was investigated by comparing the therapeutic outcomes of SUI patients treated with iVES to those who underwent a trans-obturator tape (TOT) implantation surgery, where a mid-urethral sling was implanted without electric stimulation.

Patients and methods

Urodynamic and viscoelastic data were collected from 21 SUI patients treated with a regimen combining iVES and biofeedback-assisted pelvic floor muscle training (iVES-bPFMT; 20-min iVES and 20-min bPFMT sessions, twice per week, for 3 months). This regimen complied with ethical standards. Data from 21 SUI patients who received TOT implantation were retrospectively analyzed. Mean compliance (Cm), infused volume (Vinf), and threshold pressure (Pthr) from the pressure-flow/volume investigations were assessed.

Results

Compared with the pretreatment control, iVES-bPFMT consistently and significantly increased Cm (18/21; 85%, p = 0.017, N = 21) and Vinf (16/21; 76%, p = 0.046; N = 21) but decreased Pthr (16/21; 76%, p = 0.026, N = 21). In contrast, TOT implantation did not result in consistent or significant changes in Cm, Vinf, or Pthr (p = 0.744, p = 0.295, p = 0.651, respectively; all N = 21).

Conclusion

Our results provide viscoelastic and thermodynamic evidence supporting an additional benefit of iVES-bPFMT to bladder storage in SUI patients by modifying bladder compliance, possibly due to the potentiated hypogastric tone, which did not occur in TOT-treated SUI patients.Clinical trial registration: ClinicalTrials.gov, NCT02185235 and NCT05977231.

Maintaining A Long-Term Practice of Daily Pelvic Floor Muscle Exercises: What Do Childbearing Women Think?

INTRODUCTION

To be effective, pelvic floor muscle therapy (PFMT) exercises should be intense, be practiced consistently, and include clinical support. Many women do not adhere to a consistent PFMT program, compromising the resolution or prevention of urinary incontinence (UI). This study aimed to answer 2 key questions: What prevents women from performing PFMT long term, and what can health care providers do to support women to perform them?

METHODS

Postpartum women from 4 sites in the United States completed a questionnaire about experiences with PFMT or Kegel exercises during and after pregnancy. This study focused on one of the 7 open-ended questions: What would prevent you from performing Kegels lifelong? Thematic analysis was implemented via an inductive approach using Braun and Clarke's 6-phase process.

RESULTS

Three salient themes emerged that help explain factors that prevent women from adhering to a daily PFMT routine: (1) life gets in the way, (2) inadequate PFMT education and instruction, and (3) disconnect exists about long-term consequences. The sample included 368 participants.

DISCUSSION

The themes were congruent with the limited body of qualitative literature on experience with PFMT exercises. This study was able to identify areas of need in the US maternal health care system to help childbearing people adopt daily PFMT, such as (1) inadequate parental leave and childcare support, (2) no formalized education related to UI and PFMT and a lack of pelvic health promotion, (3) lacking prioritization of long-term PFMT, and (4) the need to dispel the acceptance that UI postbirth is normal. Health care providers should prioritize interactive education, emphasizing how to correctly perform PFMT and the importance and effectiveness of integrating clinical support. To adequately encompass pelvic floor health care and education up to one year postbirth, changes are needed to the US perinatal health care system, providing sufficient insurance reimbursement and parental social support programs.

Real-World Evidence From a Digital Health Treatment Program for Female Urinary Incontinence: Observational Study of Outcomes Following User-Centered Product Design

BACKGROUND

Urinary incontinence (UI) affects millions of women with substantial health and quality-of-life impacts. Supervised pelvic floor muscle training (PFMT) is the recommended first-line treatment. However, multiple individual and institutional barriers impede women's access to skilled care. Evidence suggests that digital health solutions are acceptable and may be effective in delivering first-line incontinence treatment, although these technologies have not yet been leveraged at scale.

OBJECTIVE

The primary objective is to describe the effectiveness and safety of a prescribed digital health treatment program to guide PFMT for UI treatment among real-world users. The secondary objectives are to evaluate patient engagement following an updated user platform and identify the factors predictive of success.

METHODS

This retrospective cohort study of women who initiated device use between January 1, 2022, and June 30, 2023, included users aged ≥18 years old with a diagnosis of stress, urgency, or mixed incontinence or a score of >33.3 points on the Urogenital Distress Inventory Short Form (UDI-6). Users are prescribed a 2.5-minute, twice-daily, training program guided by an intravaginal, motion-based device that pairs with a smartphone app. Data collected by the device or app include patient-reported demographics and outcomes, adherence to the twice-daily regimen, and pelvic floor muscle performance parameters, including angle change and hold time. Symptom improvement was assessed by the UDI-6 score change from baseline to the most recent score using paired 2-tailed t tests. Factors associated with meeting the UDI-6 minimum clinically important difference were evaluated by regression analysis.

RESULTS

Of 1419 users, 947 met inclusion criteria and provided data for analysis. The mean baseline UDI-6 score was 46.8 (SD 19.3), and the mean UDI-6 score change was 11.3 (SD 19.9; P<.001). Improvement was reported by 74% (697/947) and was similar across age, BMI, and incontinence subtype. Mean adherence was 89% (mean 12.5, SD 2.1 of 14 possible weekly uses) over 12 weeks. Those who used the device ≥10 times per week were more likely to achieve symptom improvement. In multivariate logistic regression analysis, baseline incontinence symptom severity and maximum angle change during pelvic floor muscle contraction were significantly associated with meeting the UDI-6 minimum clinically important difference. Age, BMI, and UI subtype were not associated.

CONCLUSIONS

This study provides real-world evidence to support the effectiveness and safety of a prescribed digital health treatment program for female UI. A digital PFMT program completed with visual guidance from a motion-based device yields significant results when executed ≥10 times per week over a period of 12 weeks. The program demonstrates high user engagement, with 92.9% (880/947) of users adhering to the prescribed training regimen. First-line incontinence treatment, when implemented using this digital program, leads to statistically and clinically substantial symptom improvements across age and BMI categories and incontinence subtypes.

Randomised controlled pilot trial to assess effect of electrical stimulation of weak pelvic floor muscles

INTRODUCTION AND HYPOTHESIS

Pelvic floor muscle training (PFMT) has level 1A scientific evidence for the treatment of urinary incontinence and pelvic organ prolapse. Past studies, however, have often excluded women with very weak pelvic floor muscles (PFM). The aim was to investigate the hypothesis that intravaginal electrical stimulation (iES) improves PFM strength more than PFMT in women with weak PFM, and to use these results to calculate sample size required for a future large randomised controlled trial (RCT).

METHODS

This assessor-blinded pilot RCT had a two arm, parallel design with computer-generated Randomisation. Both groups were offered 12 one-to-one physiotherapy sessions over a 6-month period. The iES group received individual tailored electrical pulse parameters. The PFMT group received PFM exercises, with the addition of facilitation techniques at therapy sessions. A power calculator was used to calculate sample size.

RESULTS

Fifteen women were recruited. Eight were randomised to iES and 7 to PFMT. Two subjects dropped out of the iES group. Median age was 49 years (range 36-77) and parity 2.1 (range 1-3). Both groups showed increases in PFM strength measured by manometery (iES 12.3, SD 12.0 vs PFMT 10.0, SD 8.1) cmH2O. There was no significant difference between groups. With a power of 0.80 we need a sample size of 95 women in each group to detect a difference between groups.

CONCLUSION

There was no significant difference between the groups in improvements in PFM strength. To detect a difference, we would have required 95 women in each group.

Symptomatology and knowledge regarding pelvic floor dysfunctions and influence of gender stereotypes in female athletes

Pelvic floor dysfunctions (PFD) are highly prevalent among females who do athletics, a sport requiring jumping, strength, and running. Although educational approaches are useful options, the educational need for this particular population remains unknown. The objective of the present study was to describe the level of knowledge regarding PFD and its relationship with symptomatology and gender stereotypes in female athletes in Spain. A total of 255 female athletes completed an anonymous online survey to explore their knowledge regarding urinary incontinence (UI), pelvic organ prolapse (POP), anal incontinence (AI), and sexual dysfunction (SexD), as well as their PFD symptoms and gender stereotyped beliefs related to sport. Educational level and sports characteristics (training volume, experience, and athletic modality) were also explored. Participants demonstrated a low level of knowledge in terms of POP (52.5%), AI (64.0%), and SexD (40%), but not for UI (70.8%). The proportion of PFD complaints was 63.5% for dyspareunia, 51.8% for urine leakage, 42.4% for pelvic pain, 17.3% for AI, and 9.0% for POP, with no associations with knowledge (p > 0.05). Lower knowledge about UI and SexD was related to greater gender stereotypes (p < 0.05) and rejection of professional healthcare (p = 0.010). As a conclusion, the level of knowledge about PFD was low in female athletes who train and compete in athletics in Spain, mainly with regard to sexual dysfunction. Although 63.5% of athletes had dyspareunia and 51.8% urinary leakages, symptomatology was not associated with level of knowledge. However, a lower level of knowledge was associated with more stereotyped beliefs and rejection of professional healthcare for PFD. These findings confirm the need to design appropriate educational interventions to disseminate information on all the types of PFD, particularly sexual contents. The potential influence of gender stereotypes makes it appropriate to include the gender perspective in these interventions.

Pelvic floor therapy program for the treatment of female urinary incontinence in Belize: a pilot study

Introduction

Urinary incontinence (UI) is highly prevalent in low- and middle-income countries (LMIC). Concurrently, the availability of surgical or conservative UI treatments in LMIC is limited.

Methods

We conducted a prospective feasibility study of Belize women with UI treated with pelvic floor physical therapy (PFPT) and education (PFE). Patients received individual PFPT/PFE over 2 days, consisting of biofeedback-enhanced PFMT in addition to behavioral, dietary, and general pelvic education. Patient completed a daily 6-month home regimen including 7 PFMT exercises (total 70 repetitions) comprising both endurance and quick flick exercises. Patients also performed comprehensive dietary and behavioral modification activities. Outcomes were assessed at baseline and 6-months, including validated symptom (ICIQ-FLUTS) and QOL (IIQ-7) questionnaires, and strength testing (PERFECT score, perineometry).

Results

Twenty-eight patients underwent baseline assessment. Four patients were lost to in-person 6-month follow-up, with two of these patients completing subjective assessment only by telephone. The mean (±SD) patient age, BMI, and parity were 50.0 (±10.0) years, 33.2 (±5.8), and 2.8 (±1.5). Provider assessment demonstrated patient comprehension of basic, endurance, and quick flick pelvic floor contractions in 28 (100%), 24 (86%), and 24 (86%) patients, respectively. At 6-month follow-up, significant improvements were seen across multiple validated questionnaire and strength measurement assessments. Median patient-reported improvement level was 7.0 on a 10-point Likert scale.

Discussion

Study patients demonstrated good understanding of PFMT/PFE and program completion was associated with significant improvements across a variety of subjective incontinence and quality of life outcomes, as well as objective strength testing.

Effect of Pelvic Floor Muscle Training With Smartphone Reminders on Women in the Postpartum Period: A Randomized Controlled Trial

IMPORTANCE

Standard postpartum pelvic floor muscle training (PFMT) can effectively reduce the incidence of pelvic floor dysfunction diseases.

OBJECTIVE

This study aimed to evaluate the adherence of PFMT with smartphone application reminders on women in the postpartum period.

STUDY DESIGN

We conducted a randomized controlled trial. This single-center randomized (1:1) controlled study included primiparous women admitted to Tongji Hospital between March 2022 and June 2022 (ChiCTR2200059157). Every puerpera was given pelvic floor muscle (PFM) assessment and PFMT guidance at 6 weeks after delivery. After randomization, women in the intervention group received daily training reminders from the smartphone application WeChat. Adherence to PFMT, a symptom of stress urinary incontinence, and PFM characteristics were measured 3 months later.

RESULTS

A total of 148 participants were included in the final analysis (76 in the intervention group and 72 in the control group). The adherence rate of daily PFMT was higher in the intervention group than in the control group (53.9% vs 20.8%, P = 0.00) at 3-month follow-up. In addition, participants in the intervention group showed higher peak surface electromyography of PFMs (39.8 ± 6.2 vs 37.5 ± 5.9 μV, P = 0.03) and longer PFM endurance (8.1 ± 2.0 vs 7.3 ± 2.0 seconds, P = 0.01) than in the control group, whereas there was no difference between the 2 groups in International Consultation on Incontinence Questionnaire-Short Form ( P = 0.60) and the Patient Global Impression of Improvement scores ( P = 1.00).

CONCLUSIONS

Smartphone application-based PFMT could increase adherence and improves electromyography of PFMs in the short term but did not affect stress urinary incontinence symptoms in women in the postpartum period.

Management of mixed urinary incontinence: IUGA committee opinion

INTRODUCTION AND HYPOTHESIS

Mixed urinary incontinence (MUI) is defined by the International Urogynecology Association (IUGA) and International Continence Society as the complaint of involuntary leakage of urine associated with urgency and also with exertion, effort, sneezing or coughing. It therefore implies the coexistence of both stress urinary incontinence (SUI) and urgency urinary incontinence (UUI). MUI is a heterogeneous diagnosis that requires an assessment of its individual components of SUI and UUI. Management requires an individualised approach to the symptom components. The aim of this review is to identify the assessment/investigations and management options for MUI.

METHODS

A working subcommittee from the IUGA Research & Development (R&D) Committee was created and volunteers invited from the IUGA membership. A literature review was performed to provide guidance focused on the recommended assessment and management of MUI. The document was then evaluated by the entire IUGA R&D Committee and IUGA Board of Directors and revisions made. The final document represents the IUGA R&D Committee Opinion.

RESULTS

The R&D Committee MUI opinion paper provides guidance on the assessment and management of women with MUI and summarises the evidence-based recommendations.

CONCLUSIONS

Mixed urinary incontinence is a complex problem and successful management requires alleviation of both the stress and urge components. Care should be individualised based on patient preferences. Further research is needed to guide patients in setting goals and to determine which component of MUI to treat first. The evidence for many of the surgical/procedural treatment options for MUI are limited and needs to be explored in more detail.

Novel online comprehensive pelvic floor therapy program following prostatectomy

Background

Although pelvic floor muscle training (PFMT) is widely shown to improve post-prostatectomy incontinence (PPI), numerous barriers impede access to formal PFMT and include the limited availability of specialized therapists and financial or scheduling barriers. To address these barriers, we developed a novel online program delivering comprehensive long-term PFMT, pelvic floor education (PFE), and dietary/behavioral modification education. This study is a prospective interim analysis of online PFMT/PFE (oPFMT/PFE), with focus on feasibility, satisfaction, and continence outcomes.

Methods

Patients anticipating robotic-assisted laparoscopic prostatectomy (RALP) were recruited (6/2021-9/2022) for oPFMT/PFE. oPFMT/PFE comprises a 12-month program of 3 phases, including multiple exercises with varied contraction types and duration, and comprehensive dietary and behavioral technique education. Incontinence and quality of life (QOL) outcomes are assessed at 3 weeks, 3, 6, and 12 months following RALP using validated International Consultation on Incontinence Questionnaire Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) and Incontinence Impact Questionnaire (IIQ-7) questionnaires and additional items assessing satisfaction, improvement, and daily pad use. Primary study outcomes included ICIQ-MLUTS stress urinary incontinence (SUI) domain score (SDS) and SUI cure [ICIQ SUI domain score (SDS) =0]. Interim 6-month analysis was performed using mixed effects linear regression and mixed effects Poisson regression.

Results

Analysis included 21 men (64±6 years). At 6-month follow-up, men undergoing oPFMT/PFE showed significant improvement in SDS compared to the 3-week time point [mean ± standard error (SE) =1.05±0.24 vs. 0.45±0.17, P=0.011], but still experienced higher scores than at baseline (P=0.017). Six-month patient-reported improvement averaged 7.42±0.74 (10-point Likert scale). All (100%) of 19 respondents (2 missing data) found the program easy to use, educational, and would recommend it to others, with 89% expressing satisfaction with the program. During patient interview at 6-month follow-up, no men reported inability to access the program online or any adverse events. Finally, IIQ-7 score improved significantly from the 3-week timepoint (4.47±1.10) at both time points (3-month 1.14±0.44, P<0.001 and 6-month 1.10±0.37, P<0.001), and neither 3- nor 6-month scores differed from baseline (P=0.808 and P=0.444, respectively).

Conclusions

Our novel oPFMT/PFE yields significant improvements to validated urinary incontinence (UI) and QOL measures, providing a valuable and accessible treatment option for PPI.

Pelvic floor muscle training with biofeedback or feedback from a physiotherapist for urinary and anal incontinence after childbirth - a systematic review

BACKGROUND

Childbirth is one of the biggest risk factors for incontinence. Urinary and anal incontinence can cause pain and social limitations that affect social life, cohabitation, and work. There is currently no up-to-date literature study on the effect of pelvic floor muscle training with feedback from a physiotherapist, which involves verbal instructions based on vaginal and anal digital palpation, compared to treatment without feedback (e.g., recommendations for pelvic floor muscle training).

AIM

The objective of this systematic review was to examine the scientific evidence regarding the impact of pelvic floor muscle training (PFMT) with feedback from a physiotherapist and/or biofeedback on urinary and anal incontinence in women during the first six months following vaginal delivery, compared to treatment without feedback.

METHODS

The literature search was conducted in the databases PubMed, Cochrane, and CINAHL. In addition, a manual search was conducted. The search terms consisted of MeSH terms and synonyms in the respective search block including population, intervention, and study design, as well as the terms pelvic floor and postpartum. An evaluation of each included study was conducted for methodological quality, evidence value, and clinical relevance.

RESULTS

Eight studies were included, three of which showed a significant difference between groups, in favor of the intervention group that received pelvic floor muscle training with feedback from a physiotherapist and/or biofeedback. Due to the varying results and insufficient quality for the majority of the studies, the scientific basis was considered insufficient.

CONCLUSION

The scientific evidence for pelvic floor muscle training with feedback from a physiotherapist or biofeedback on postpartum urinary and anal incontinence compared to treatment without feedback is considered insufficient. Further research on the subject is needed. The study is registered in PROSPERO CRD42022361296.

Development and evaluation of a rehabilitation training compliance scale for patients with urinary incontinence

BACKGROUND

Urinary incontinence treatment includes conservative treatment, physical devices, medication, and surgery. Pelvic floor muscle training combined with bladder training is among the most effective, non-invasive, and economical ways to treat urinary incontinence, and compliance with training is essential in urinary incontinence treatment. Several instruments assess pelvic floor muscle training and bladder training. However, no tool has been found that assesses compliance with pelvic floor muscle training when combined with bladder training for urinary incontinence. This study aimed to develop a rehabilitation training compliance scale for patients with urinary incontinence and to evaluate its validity and reliability.

METHODS

This study was performed in two tertiary hospitals in Hainan, China between December 2020 and July 2021, 123 patients were included. A literature review, group discussions, and two rounds of letter consultations were performed to acquire the item pool and finalise the 12 items for this scale. Exploratory and confirmatory factor analysis, Cronbach's α, split-half reliability, test-retest reliability, content validity, construct validity, convergent and discriminant validity, and criterion-related validity were used to examine the items in the scale.

RESULTS

A 12-item scale comprising three factors accounted for 85.99% of the variance in the data. The Cronbach's α, split-half reliability, test-retest reliability, and content validity index of the scale were 0.95, 0.89, 0.86, and 0.93, respectively. Comparison with the Chen pelvic floor muscle exercise self-efficacy scale showed high calibration correlation validity (coefficient = 0.89).

CONCLUSIONS

The training compliance scale developed in this study is a valid and reliable measurement tool to assess pelvic floor muscle training and bladder training compliance in patients with urinary incontinence.

Prevalence and severity of urinary incontinence and associated factors in Iranian postmenopausal women: a cross-sectional study

BACKGROUND

Urinary incontinence (UI) is one of the most common symptoms during menopause, leading to a decreased quality of life and limited social activities. This study aimed to determine the prevalence and severity of urinary incontinence and associated risk factors in postmenopausal women.

METHODS

It was a cross-sectional study using cluster sampling on 433 postmenopausal women in Tabriz-Iran, 2021-2022. Data were collected using questionnaires of socio-demographic characteristics, Questionnaire for Urinary Incontinence Diagnosis (QUID), and International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UISF). Multivariate logistic regression was used to determine factors related to urinary incontinence.

RESULTS

The overall prevalence of urinary incontinence was 39.5%; 20.6% stress urinary incontinence (SUI), 10.4% urgency urinary incontinence (UUI), and 8.5% mixed urinary incontinence (MUI). Multivariate logistic regression analysis showed that the prevalence of SUI (aOR 0.38; 95% CI 0.18-0.77) and UUI (aOR 0.38; 95% CI 0.15-0.94) was significantly lower in women with three childbirths than the ones with fewer childbirths. Also, the odds of UUI increased significantly in women at the 50-55 age range (aOR 3.88; 95% CI 1.16-12.93) than those less than 50 years.

CONCLUSION

Due to the high prevalence of urinary incontinence in postmenopausal women, caregivers should screen for early diagnosis and appropriate treatment of urinary incontinence to prevent its destructive impact on the quality of life.

Bio-Physics Approach to Urinary Incontinence Disabilities

BACKGROUND

The terminology of urinary incontinence (UI) and pelvic floor dysfunctions is complex. It affects quality of life and daily activities in personal, social, and professional fields. Managing UI without pharmacologic therapies is effective with a low risk of adverse effects and a large benefit for increasing continence rates. The aim of this preliminary retrospective observational study is to evaluate the effectiveness of the association between manual therapy and focused mechano-acoustic vibrations in women with nonspecific UI.

MATERIALS AND METHODS

A group of 15 incontinent women (mean age 59.5 ± 11.4), referred to the Physiotherapy Center, Rehabilitation and Re-education (Ce.Fi.R.R.), located at the University "Gabriele d'Annunzio" of Chieti-Pescara from January 2019 December 2021, were enrolled after medical examination. The women were evaluated at T0 (admission protocol), T1 (after 8 weeks), and T2 (after 12 weeks). All patients received the rehabilitation protocol twice a week for a total of 8 weeks (T1) and were reevaluated after 12 weeks (T2). Outcome measures were: the Pelvic Floor Disability Index, the Pelvic Floor Impact Questionnaire-7, and the MyotonPRO.

RESULTS

The analysis of MyotonPRO data showed no significant improvements in all parameters. The PFDI-20 and PFIQ-7 questionnaire results showed a significant reduction in scores between T0 and T2.Results over time of the ANOVA values confirming the significant differences in the PFDI-20 and PFIQ-7 questionnaire results but not in the MyotonPRO variables.

CONCLUSIONS

Despite limitations and no significant results, this study demonstrated that the integration of manual and focused mechano-acoustic vibrations therapy improved the symptoms of UI and reduced its psychosocial impact. Further experience could be required to establish the place of this integrated approach in achieving long-term improvements in UI.
