Urinary incontinence following obstetric fistula repair

Treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries: A scoping review

BACKGROUND

Obstetrical fistula is an abnormal opening between the reproductive tract and lower urinary and/or gastrointestinal tract resulting from obstetrical complications, affecting nearly two million women worldwide. It imposes physical, economic, social, and mental consequences on the affected women. Treatment outcomes vary and, mostly, surgical treatment results in improved quality of life and successful subsequent pregnancy for survivors.

OBJECTIVES

The review aimed to chart and examine the treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries.

SEARCH STRATEGY

This is a scoping review study to identify treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries. The search was conducted from databases (PUBMED, Embase, CINAHL, Scopus, and Web of Science), and gray literature (Google Scholar, Google, and conference proceedings).

SELECTION CRITERIA

The eligibility criteria were constructed using a participant, concept, and context framework and included study types of primary research, reviews, and reports. Studies without full text and in languages other than English were excluded.

DATA COLLECTION AND ANALYSIS

The relevant characteristics of the included studies were extracted on an Excel spreadsheet and analyzed to chart treatment outcomes.

MAIN FINDINGS

The review examined the full text of 57 studies on the treatment outcomes of obstetrical fistula. The findings were grouped into two themes: early and late outcomes. The early outcomes included incontinence, surgical-site infection, urine retention, hemorrhage, and retained catheter. The late outcomes included fistula recurrence, residual incontinence, quality of life, reproductive issues, mental health, family and social support, and financial status.

CONCLUSION

The treatment outcomes of obstetrical fistula can be grouped into short-term and long-term outcomes. Although this review found adequate studies for the analysis, most study designs were poor. Stronger studies are recommended in the future to guide policy and decision-making. We would like to suggest that researchers conduct systematic reviews and meta-analyses independently for short-term and long-term outcomes.

Factors Associated With Persistent Urinary Incontinence Among Women Undergoing Female Genital Fistula Surgery in the Democratic Republic of Congo From 2017 to 2019

Background

Despite high closure rates, residual urinary incontinence remains a common problem after successful closure of a vesico-vaginal fistula. The objective of this study was to identify factors associated with residual urinary incontinence in women with successful fistula closure in sites supported by the Fistula Care Plus project in the Democratic Republic of Congo (DRC).

Material and Methods

This was a retrospective cohort study using routine data extracted from the medical records of women undergoing fistula surgery in three hospitals supported by the Fistula Care Plus project in DRC between 2017 and 2019. We analyzed factors associated with residual urinary incontinence among a subsample of women with closed fistula at discharge. We collected data on sociodemographic, clinical, gynecological-obstetrical characteristics, and case management. Univariate and multivariate analyses were performed to determine the factors associated with residual urinary incontinence.

Results

Overall, 31 of 718 women discharged with closed fistula after repair (4.3%; 95% CI: 3.1-6.1) had residual incontinence. The leading causes identified in these women with residual incontinence were urethral voiding (6 women), short urethra (6 women), severe fibrosis (3 women) and micro-bladder (2 women). The prevalence of residual incontinence was higher among women who received repair at the Heal Africa (6.6%) and St Joseph's (3.7%) sites compared with the Panzi site (1.7%). Factors associated with increased odds of persistent urinary incontinence were the Heal Africa repair site (aOR: 54.18; 95% CI: 5.33-550.89), any previous surgeries (aOR: 3.17; 95% CI: 1.10-9.14) and vaginal surgical route (aOR: 6.78; 95% CI: 1.02-45.21).

Conclusion

Prior surgery and repair sites were the main predictors of residual incontinence after fistula closure. Early detection and management of urinary incontinence and further research to understand site contribution to persistent incontinence are needed.

Characterizing persistent urinary incontinence after successful fistula closure: the Uganda experience

BACKGROUND

Obstetric fistula is a devastating childbirth injury. Despite successful closure of the fistula, 16% to 55% of women suffer from persistent urinary incontinence after surgery.

OBJECTIVE

This study assessed the type and severity of persistent incontinence after successful fistula closure and its impact on the quality of life of Ugandan women post-fistula treatment.

STUDY DESIGN

This cross-sectional study enrolled women with a history of obstetric fistula repair who continued to have persistent urinary incontinence (cases, N=36) and women without incontinence (controls, N=52) after successful fistula closure. Data were collected in central and eastern Uganda between 2017 and 2019. All the participants completed a semistructured questionnaire. Cases underwent a clinical evaluation and a 2-hour pad test and completed a series of incontinence questionnaires, including two novel tools designed to assess the severity of incontinence in low-literacy populations.

RESULTS

Cases were more likely to have acquired a fistula during their first delivery (63% vs 37%, P=.02), were younger when they developed a fistula (20.3±5.8 vs 24.8±7.5 years old, P=.003), and were more likely to have had >2 fistula surgeries (67% vs 2%, P≤.001). Cases reported a much higher rate of planned home birth for their index pregnancy compared to controls (44% vs 11%), though only 14% of cases and 12% of controls actually delivered at home. Cases reported higher rates of pain with intercourse (36% vs 18%, P=.05), but recent sexual activity status (intercourse within the previous six months) was not significantly different between the groups (47% vs 62%, P=.18). Among cases, 67% reported stress incontinence, 47% reported urgency incontinence, and 47% reported mixed incontinence. The cough stress test was successfully done with 92% of the cases, and of these, almost all (97%) had a positive cough stress test. More than half (53%) rated their incontinence as "very severe," which was consistent with objective findings. The 24-hour voiding diary indicated both high urinary frequency (average 14) and very frequent leakage episodes (average 20). Two-hour pad-tests indicated that 86% of cases had >4 g change in pad weight within 2 hours. Women with more severe incontinence reported a more negative impact on their quality of life. The mean score of the International Consultation on Incontinence Questionnaire-Quality of Life was 62.77±12.76 (range, 28-76, median=67), with a higher score indicating a greater impact on the quality of life. There was also a high mental health burden, with both cases and controls reporting high rates of suicidal ideation at any point since developing fistula (36% vs 31%, P=.67).

CONCLUSION

Women with obstetric fistulas continue to suffer from severe persistent urinary incontinence even after successful fistula closure. Both stress and urgency incontinence are highly prevalent in this population. Worsening severity of incontinence is associated with a greater negative impact on the quality of life.
