Factors influencing urinary fistula repair outcomes in developing countries: a systematic review

Risk factors for developing residual stress urinary incontinence after vesico-vaginal fistula repair: A retrospective cohort study

BACKGROUND

Previous studies have identified predictors for residual urinary incontinence after successful closure of fistula. However, these findings remain uncertain because the predictors vary from one study to another. The present study aimed to examine the risk of residual stress urinary incontinence after successful closure of vesico-vaginal fistula (VVF).

MATERIALS AND METHODS

We conducted a multicenter retrospective cohort study over 07-years period, from 1st January, 2010 to 31 December, 2016. We included women who underwent VVF repair in one of the seven fistula centers. At three months postoperatively, a cough test was performed among patients who had their fistula successfully closed. The predicted outcome was the urinary continence status after sussessful closure of the fistula and was categorized as (Residual stress urinary incontinence and No Residual stress urinary incontinence). Multivariable binary logistic regression model was performed to analyze association between outcome and predictors.

RESULTS

Overall fistula closure rate at 3 months was 88.6% (404/456). Of the patients who had their fistula successfully closed, 16.3% (66/404) experienced a residual stress urinary incontinence. Risk factors for residual stress urinary incontinence in univariate analysis were: urethro-vesical junction involvement, circumferential fistula, Goh type 3, fistula size greater than 3cm, previous fistula repair, urethra involvement. Three independent predictors have been identified: urethro-vesical junction involvement, previous fistula repair and type 3 of Goh's classification.

CONCLUSION

This study showed that the rate of residual stress urinary incontinence is high in our setting. The involvement of sphincteric mechanism is the main predictor.

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.

The burden of iatrogenic obstetric fistulas in Sub-Saharan Africa: Systematic review and meta-analysis protocol

BACKGROUND

Obstetric fistulas are abnormal open connection(s) between the vagina and the urinary tract or the rectum resulting from tragic injuries sustained by mothers during childbirth that lead to urine and/or faecal incontinence. Due to the rapidly growing middle class in sub-Saharan Africa (SSA) and the corresponding quest for hospital delivery and caesarean section, surgery-related (iatrogenic) obstetric fistulas are on the rise. Worryingly, there is scanty data on surgery-related fistulas. This review aims to collate empirical evidence on the magnitude of iatrogenic obstetric fistulas in SSA, generate country-specific data and explore factors that influence obstetric surgery-related fistulas.

METHODS

All relevant databases, PubMed, LILACS, CINAHL, SCOPUS and Google Scholar will be searched from 1st January 2000 to 31st March 2024 using search terms developed from the major concepts in the title without restrictions by language. The Cochrane Library, African Journals Online, Data Base of African Thesis and Dissertations Including Research (DATAD-R D Space) and preprint repositories will also be searched. Reference lists of relevant studies will be searched and experts in the field will be contacted for additional (unpublished) studies. The search output will be exported to Endnote where duplicate studies will be removed. The deduplicated studies will be exported to Rayyan where study screening and selection will be conducted. At least two authors will independently select studies, extract data and assess quality in the included studies using pretested tools. Disagreements between reviewers will be resolved through discussion. Data analysis will be performed with RevMan 5.4. Comparative binary outcomes will be reported as odds ratio (OR) or risk ratio (RR) and for continuous outcomes, mean difference and standard deviations (SDs) will be used. Non-comparative studies will be analysed as weighted proportions. Heterogeneity between studies will be assessed graphically and statistically, and where a significant level is detected, the random-effects model meta-analysis will be performed. All estimates will be reported with their 95% confidence intervals (CIs). Where data permit, we will conduct subgroup and sensitivity analyses to test the robustness of the estimates on key quality domains. The overall quality of the evidence will be assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation).

EXPECTED STUDY OUTCOMES

This systematic review and meta-analysis uses rigorous methods and best practices to attempt to collate all empirical evidence and estimate country-specific proportions of iatrogenic (surgery-related) fistulas among obstetric fistula patients across countries in SSA. This review will explore context-specific variables, provide insights into their impact and relate them to the type and experience of personnel performing the obstetric procedures that lead to obstetric fistulas. The findings of the full review are expected to inform the development of national and regional Training Programs for Medical Officers, support the development of a consensus "minimum acceptable standard of care" and inform quality assurance standards for clinicians involved in the provision of surgical obstetric care.

Proportions and determinants of successful surgical repair of obstetric fistula in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Obstetric fistula is a serious and debilitating problem resulting from tissue necrosis on the reproductive and urinary and/or lower gastrointestinal tract organs due to prolonged labor. Primary studies of the treatment of obstetric fistulae report significantly variable treatment outcomes following surgical repair. However, no systematic review and meta-analysis has yet estimated the pooled proportion and identified the determinants of successful obstetric fistula surgical repair.

OBJECTIVE

To estimate the proportion and identify the determinants of successful surgical repair of obstetric fistulae in low- and middle-income countries.

METHODS

The protocol was developed and registered at the International Prospective Register of Systematic Reviews (ID CRD42022323630). Searches of PubMed, Embase, CINAHL, Scopus databases, and gray literature sources were performed. All the accessed studies were selected with Covidence, and the quality of the studies was examined. Finally, the data were extracted using Excel and analyzed with R software.

RESULTS

This review included 79 studies out of 9337 following the screening process. The analysis reveals that 77.85% (95%CI: 75.14%; 80.56%) of surgical repairs in low and middle-income countries are successful. Women who attain primary education and above, are married, and have alive neonatal outcomes are more likely to have successful repair outcomes. In contrast, women with female genital mutilation, primiparity, a large fistula size, a fistula classification of II and above, urethral damage, vaginal scarring, a circumferential defect, multiple fistulae, prior repair and postoperative complications are less likely to have successful repair outcomes.

CONCLUSION

The proportion of successful surgical repairs of obstetric fistula in low and middle-income countries remains suboptimal. Hence, stakeholders and policymakers must design and implement policies promoting women's education. In addition, fistula care providers need to reach and manage obstetric fistula cases early before complications, like vaginal fibrosis, occur.

Urinary incontinence following successful closure of obstetric vesicovaginal fistula repair in Southern Ethiopia

BACKGROUND

Urinary incontinence (UI) after successful closure of obstetric vesicovaginal fistula (VVF) repair is a widely recognized public health problem. However, there is insufficient research evaluating the factors associated with UI after successful obstetric VVF repair in Ethiopia.

OBJECTIVES

The main aim of this study was to assess the magnitude and associated factors of UI following the successful closure of obstetric VVF repair at the Yirgalem Hamlin Fistula Center in the Sidama region of southern Ethiopia.

METHODS

A retrospective cross-sectional analytical study was performed on patients who underwent obstetric VVF repair at the Yirgalem Hamlin Fistula Center between 2016 and 2020. The data were collected from September to October 2021. EPI Data Version 3.1 and SPSS Version 25.0 were used for data entry and analysis. A multivariable binary logistic regression model was used for all variables significant in the bivariate binary logistic analysis to determine the association between the independent variables and outcome variables. The data are presented in tables and figures. Variables with a p-value < 0.05 were considered to be statistically associated with the study outcome.

RESULTS

In total, 499 study subjects were included. The magnitude of UI after successful closure of obstetric VVF repair was 23.25%. A Goh type 4 fistula (AOR = 4.289; 95% CI 1.431, 12.852), a fistula size > 3 cm (AOR = 8.855; 95% CI 4.786, 16.382), a partially damaged urethra (AOR = 2.810; 95% CI 1.441, 5.479), and a completely destroyed urethra (AOR = 5.829; 95% CI 2.094, 16.228) were found to be significantly associated factors with the outcome variable.

CONCLUSIONS

Nearly one in four patients who had successful closure of obstetric VVF repair at the Yirgalem Hamlin fistula center had UI, which is above the WHO recommendations. The presence of a Goh type 4 fistula, large fistula size, and damaged urethral status significantly affect the presence of UI. Therefore, interventions are necessary to prevent and manage UI among patients who underwent obstetric VVF repair and had a closed fistula.

Impact of Beyond Fistula programming on economic, psychosocial and empowerment outcomes following female genital fistula repair: A retrospective study

OBJECTIVE

To retrospectively assess changes in economic status, psychosocial status and empowerment among women who participated in Beyond Fistula reintegration programming following fistula repair.

METHODS

We conducted a retrospective study among 100 Beyond Fistula program participants capturing sociodemographic characteristics, obstetric and fistula history, program participation, and our primary outcomes: economic status, psychosocial status, and empowerment via quantitative survey at two time points: before program participation and currently. Data were collected from November 2020 to July 2021 from 2013 to 2019 program participants. We compared outcomes across these two time points using paired t tests or McNemar's tests.

RESULTS

The proportion of individuals owning property (28.0% vs. 38.0%, P = 0.006), having a current source of income (19.0% vs. 56.0%, P < 0.001), and saving or investing income (11.0% vs. 37.0%, P < 0.001) increased significantly from pre- to post-programming. We also identified statistically significant increases from pre- to post-programming in self-esteem (5.0 [IQR 4.0-5.0] vs. 5.0 [IQR 5.0-5.0], P < 0.001), reintegration (53.0 [IQR 43.0-69.0] vs. 65.0 [IQR 51.0-72.0], P < 0.001) and level of input into household economic decision making (2.0 [SD 1.0] vs. 2.3 [SD 1.0], P = 0.004).

CONCLUSION

Beyond Fistula programming likely improved economic status, psychosocial status, and empowerment of participants. Post-surgical interventions incorporating a holistic approach can advance recovery through supporting psychosocial and economic wellbeing and should be offered to women undergoing genital fistula repair.

Obstetric fistula repair failure and its associated factors among women who underwent repair in sub-Saharan Africa. A systematic review and meta-analysis

BACKGROUND

Obstetric fistula repair failure can result in increased depression, social isolation, financial burden for the woman, and fistula care programs. However, there is limited, comprehensive evidence on obstetric fistula repair failure in Sub-Saharan African countries. This systematic review and meta-analysis aimed to determine the pooled prevalence of obstetric fistula repair failure and associated factors among women who underwent surgical repair in Sub-Saharan African countries.

METHODS

To identify potential articles, a systematic search was done utilizing online databases (PubMed, Hinari, and Google Scholar). The Preferred Reporting Items for Systematic Review and Meta-Analysis Statement (PRISMA) guideline was used to report the review's findings. I2 test statistics were employed to examine study heterogeneity. A random-effects model was used to assess the pooled prevalence of obstetric fistula repair failure, and the association was determined using the log odds ratio. Publication bias was investigated using the funnel plot and Egger's statistical test at the 5% level of significance. Meta-regression and subgroup analysis were done to identify potential sources of heterogeneity. The data were analyzed using STATA version 17 statistical software.

RESULTS

A total of 24 articles with 9866 study participants from 13 Sub-Saharan African countries were included in this meta-analysis. The pooled prevalence of obstetric fistula repair failure in sub-Saharan Africa was 24.92% [95% CI: 20.34-29.50%]. The sub-group analysis by country revealed that the highest prevalence was in Angola (58%, 95% CI: 53.20-62.80%) and the lowest in Rwanda (13.9, 95% CI: 9.79-18.01%). Total urethral damage [OR  =  3.50, 95% CI: 2.09, 4.91], large fistula [OR = 3.09, 95% CI: (2.00, 4.10)], duration of labor [OR = 0.45, 95% CI: 0.27, 0.76], and previous fistula repair [OR = 2.70, 95% CI: 1.94, 3.45] were factors associated with obstetric fistula repair failure.

CONCLUSION

Women who received surgical treatment for obstetric fistulas in Sub-Saharan African countries experienced more repair failures than the WHO standards. Obstetric fistula repair failure was affected by urethral damage, fistula size, duration of labor, types of fistula, and history of previous repairs. Therefore, we suggest policy measures specific to each country to provide special attention to the prevention of all risk factors, including poor nutrition, multiparty, obstructed labor, and maternal age, which can result in conditions like large fistulas, urethral damage, and repeat repair, in order to reduce obstetric fistula repair failure.

Identifying opportunities for prevention of adverse outcomes following female genital fistula repair: protocol for a mixed-methods study in Uganda

BACKGROUND

Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence, and other morbidity may occur during fistula development. Women with fistula are stigmatized, limit social and economic engagement, and experience psychiatric morbidity. Improved surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events. This study aims to quantify these adverse risks and inform clinical and counseling interventions to optimize women's health and quality of life following fistula repair through: identifying predictors and characteristics of post-repair fistula breakdown and recurrence (Objective 1) and post-repair incontinence (Objective 2), and to identify feasible and acceptable intervention strategies (Objective 3).

METHODS

This mixed-methods study incorporates a prospective cohort of women with successful vesicovaginal fistula repair at approximately 12 fistula repair centers in Uganda (Objectives 1-2) followed by qualitative inquiry among key stakeholders (Objective 3). Cohort participants will have a baseline visit at the time of surgery followed by data collection at 2 weeks, 6 weeks, 3 months and quarterly thereafter for 3 years. Primary predictors to be evaluated include patient-related factors, fistula-related factors, fistula repair-related factors, and post-repair behaviors and exposures, collected via structured questionnaire at all data collection points. Clinical exams will be conducted at baseline, 2 weeks post-surgery, and for outcome confirmation at symptom development. Primary outcomes are fistula repair breakdown or fistula recurrence and post-repair incontinence. In-depth interviews will be conducted with cohort participants (n ~ 40) and other key stakeholders (~ 40 including family, peers, community members and clinical/social service providers) to inform feasibility and acceptability of recommendations.

DISCUSSION

Participant recruitment is underway. This study is expected to identify key predictors that can directly improve fistula repair and post-repair programs and women's outcomes, optimizing health and quality of life. Furthermore, our study will create a comprehensive longitudinal dataset capable of supporting broad inquiry into post-fistula repair health. Trial Registration ClinicalTrials.gov Identifier: NCT05437939.

Predictors and outcomes of surgical repair of obstetric fistula at Mekelle Hamlin Fistula Center, Northern Ethiopia

BACKGROUND

Obstetric fistula is a medical condition that involves an opening between vagina and bladder or vagina and rectum. From 2010 to 2013, on average, around 2000 women each year had surgery for obstetric fistula in Ethiopia. The success and failure rate of obstetric fistula repair varies from center to center and is determined by many factors. Thus, this study aimed to assess the predictors and outcomes of surgical repair of obstetric fistula at Mekelle Hamlin Fistula Center (MHFC).

METHODS

A retrospective reviewed medical records of 328 patients with obstetric fistula were carried out at MHFC. Multivariable logistics regression analysis was conducted, a significant association was declared when the p-value was less than 0.05, and the strength of the association was determined by computing the odds ratio at 95% CI. The analysis was done using SPSS version 24.

RESULTS

Obstetrics fistula patients who had formal education were 13% more likely to be successfully repaired than obstetrics fistula patients who had no formal education. Additionally, obstetrics fistula patients who had a live birth were 32.325 (exp (β) = 32.325) times more likely to have had a successful repair than those who had a stillbirth.

CONCLUSION

Fistula closure was achieved in 89.3% of cases. The success rate for VVF (vesico-vaginal fistula) and RVF (recto-vaginal fistula) surgical repair was 86.9% and 100% respectively, which is higher than the WHO target. Body mass index between 18.5-24.9 kg/m2, formal education, antibiotic use, live birth, large fistula size, and home and cesarean delivery were predictors of successful closure of obstetric fistula.

Prevalence and associated risk factors for failed obstetric fistula repair in East African countries: A systematic review and meta-analysis

Objective

Obstetric fistula repair failure is a combination of unsuccessful fistula closure and/or incontinence following a successful closure. There is an inconsistent finding on the failure of obstetric fistula repair in East Africa. Therefore, this systematic review and meta-analysis aimed to determine the pooled prevalence of failed obstetric fistula repair and its associated factors among women who have undergone fistula repair in East Africa.

Methods

This systematic review and meta-analysis were written following the PRISMA guideline protocol. A web-based electronic search of PubMed, Google Scholar, and HINARI was performed to find primary studies. Additional articles were searched by cross-referencing references. A random-effects model was used to estimate the pooled prevalence of failed obstetric fistula repair. The heterogeneity of studies was weighed using I2 test statistics. Publication bias was assessed by Eggers and funnel plot test.

Results

The 16 studies that met the inclusion criteria for this systematic review and meta-analysis of failed obstetric fistula repair were included. Nonetheless, one study was used for factor analysis but not in pooled prevalence analysis. The pooled prevalence of obstetric fistula repair failure in East Africa was 26.89% (95% confidence interval: 21.71, 32.07). Labor duration > 48 h (Pooled odds ratio = 2.46; 95% confidence interval 1.58, 3.82), fistula size >3 cm (Pooled odds ratio = 3.92; 95% confidence interval 2.19, 7.05), previous fistula repair (Pooled odds ratio = 3.20; 95% confidence interval 1.94, 5.29), Goh Type 4 fistulas (Pooled odds ratio = 6.07; 95% confidence interval 2.50, 14.75), completely destructed urethra (Pooled odds ratio = 3.35; 95% confidence interval 1.69, 6.65), and severe vaginal scaring (Pooled odds ratio = 3.89; 95% confidence interval 1.99, 7.62) were significantly associated with obstetric fistula repair failure.

Conclusions

One in four women with obstetric fistula repair experienced repair failure. To fight the problem The Ministry of Health in every part of the country, in collaboration with obstetric care providers, shall intervene on factors affecting obstetric fistula repair failure to reduce or prevent the failure of obstetric fistula repair.

Predictors of outcomes in patients with repeat surgery for obstetric fistula: a retrospective review

INTRODUCTION AND HYPOTHESIS

Predictors of surgical outcomes in patients with an obstetric fistula who have been operated before should be identified in order to guide surgical strategy and optimize counseling of the patient.

METHODS

This retrospective study is aimed at identifying predictors of outcomes for repeat surgery in 346 patients who had been operated on before for an obstetrics fistula at the Fistula Care Center (FCC) in Lilongwe, Malawi. Repeat cases were only undertaken by advanced and expert surgeons. The primary outcome was successful anatomical closure, based on a negative postoperative dye test. The secondary outcomes involved urinary continence, based on a patient-reported questionnaire and an objective 1-h pad weight test. Logistic regression models were used to test the predictors for statistical significance.

RESULTS

Successful fistula closure was achieved in 288 (83%) patients and continence was achieved in 185 (64%) patients after the first repeat attempt at the FCC. Lack of urethral involvement (Goh classification: proximity to the urethra) was shown to be a good predictor of the outcomes: fistula closure and subjective and objective continence.

CONCLUSIONS

Absence of urethral involvement is an independent predictor for successful outcomes in repeat surgery for obstetric fistulas. Even in the hands of an expert surgeon, the risk of another failure in achieving anatomical closure or subjective or objective continence is between 4 and 5 times higher than when the urethra is not involved.

Women's sexual activity and experiences following female genital fistula surgery

BACKGROUND

Surgical repair has a transformative impact on the lives of women affected by female genital fistula; however, various physical, social, and economic challenges may persist postrepair and prevent complete reengagement in relationships and communities. Nuanced investigation of these experiences is needed to inform programming that aligns with women's reintegration needs.

AIM

We investigated the sexual activity resumption, experiences, and concerns of women in Uganda during the year following genital fistula repair surgery.

METHODS

Women were recruited from Mulago Hospital between December 2014 and June 2015. We collected data at baseline and 4 times postsurgery about sociodemographic characteristics and physical/psychosocial status; we also assessed sexual interest and satisfaction twice. We performed in-depth interviews with a subset of participants. We analyzed quantitative findings via univariate analyses, and qualitative findings were coded and analyzed thematically.

OUTCOMES

We assessed sexual readiness, fears, and challenges following surgical repair of female genital fistula using quantitative and qualitative measures of sexual activity, pain with sex, sexual interest/disinterest, and sexual satisfaction/dissatisfaction.

RESULTS

Among the 60 participants, 18% were sexually active at baseline, which decreased to 7% postsurgery and increased to 55% at 1 year after repair. Dyspareunia was reported by 27% at baseline and 10% at 1 year; few described leakage during sex or vaginal dryness. Qualitative findings showed wide variance of sexual experiences. Some reported sexual readiness quickly after surgery, and some were not ready after 1 year. For all, fears included fistula recurrence and unwanted pregnancy.

CONCLUSION

These findings suggest that postrepair sexual experiences vary widely and intersect meaningfully with marital and social roles following fistula and repair. In addition to physical repair, ongoing psychosocial support is needed for comprehensive reintegration and the restoration of desired sexuality.

HIGHLIGHTS

FIGO recommendations: Use of midurethral slings for the treatment of stress urinary incontinence

BACKGROUND

Stress urinary incontinence (SUI) is a global problem. It can significantly adversely impact a woman's quality of life. The use of synthetic mesh in vaginal surgery is controversial, especially when used for pelvic organ prolapse surgery. Although negative effects have been reported, the synthetic mesh midurethral sling (MUS) is considered to be safe and effective in the surgical treatment of SUI.

OBJECTIVES

To provide evidence-based data and recommendations for the obstetrician/gynecologist who treats women with SUI and performs or plans to perform MUS procedures.

METHODS

Academic searches of MEDLINE, the Cochrane Library, Embase, and Google Scholar articles published between 1987 and March 2020 were performed by a subgroup of the Urogynecology and Pelvic Floor Committee, International Federation of Gynecology and Obstetrics (FIGO).

SELECTION CRITERIA

The obtained scientific data were associated with a level of evidence according to the Oxford University Centre for Evidence-Based Medicine and GRADE Working Group system. In the absence of concrete scientific evidence, the recommendations were made via professional consensus.

RESULTS

The FIGO Urogynecology and Pelvic Floor Committee reviewed the literature and prepared this evidence-based recommendations document for the use of MUS for women with SUI.

CONCLUSIONS

Despite the extensive literature, there is a lack of consensus in the optimal surgical treatment of SUI. These recommendations provide a direction for surgeons to make appropriate decisions regarding management of SUI. The MUS is considered safe and effective in the treatment of SUI, based on many high-quality scientific publications and professional society recommendations. Comprehensive long-term data and systemic reviews are still needed, and these data will become increasingly important as women live longer. These recommendations will be continuously updated through future literature reviews.

Repair failure and associated factors among women who underwent obstetric fistula surgery in Southwest Ethiopia: A retrospective study

BACKGROUND

Surgical repair is one of the management strategies for obstetric fistulae, which are associated with tragic obstetric morbidities.

OBJECTIVE

This study assessed the proportion of repair failures and associated factors among women who underwent obstetric fistula surgery at the Mettu Hamlin Fistula Center.

DESIGN

This study is an institution-based, retrospective, cross-sectional design.

METHODS

This study included 385 patients who underwent obstetric fistula repair surgery at the Mettu Hamlin Fistula Center between 2015 and 2020. Participants were selected using a simple random sampling technique. EpiData version 3.1 and STATA version 14.2 were used for data entry and analysis, respectively. The association between obstetric fistula failure and independent variables was tested using binary logistic regression analysis. In the bivariable analysis, a p-value of less than 0.25 was used as a cut-off point to include variables in the multivariable logistic regression analysis. The statistical significance was finally set at a p-value of less than 0.05.

RESULTS

Of the 385 participants who underwent obstetric fistula surgical repair, about 18.2% (95% confidence interval = 14.6-22.3) failed to close. Larger fistula size (>3 cm) (adjusted odds ratio (AOR) = 4.6; 95% confidence interval = 2.34-8.91), urethral damage (adjusted odds ratio = 2.8; 95% confidence interval = 1.47-5.44), home delivery (adjusted odds ratio = 5; 95% confidence interval = 2.56-9.77), and malnutrition (body mass index <18.5 kg/m2) (adjusted odds ratio = 2.7; 95% confidence interval = 1.10-6.79) were variables significantly associated with obstetric fistula repair failure.

CONCLUSION

Obstetric fistula repair failure was lower in the area compared to the majority, but not all, of previous findings. Home delivery, damaged urethra, larger fistula size, and lower body mass index increased the probability of repair failure. To prevent repair failure early, it is necessary to strengthen pre- and post-operative care, including the assessment of women's nutritional status, fistula size, and urethral injury. Moreover, maternal care providers should educate mothers about the negative outcomes of home deliveries.

Survival Modeling on the Determinants of Time to Recovery from Obstetric Fistula: The Case of Mekelle Hamlin Fistula Center, Ethiopia

BACKGROUND

An obstetric fistula is an abnormal opening between the vagina, rectum, and/or bladder. Obstetric fistula has a devastating impact on women's physical, social, and psychological health. Despite the numerous health consequences in developing countries, including Ethiopia, there have been few studies on the determinants of time to recovery from obstetric fistula. Therefore, this study is aimed at addressing the gap.

METHODS

A retrospective cohort study was employed to include 328 randomly selected records of women admitted for obstetric fistula treatment at Mekelle Hamlin Fistula Center from January 2015 to 2020. Data collected from the medical records was coded and entered into SPSS software version 20 and exported to STATA 10 and R statistical software for data cleaning and data analysis. The Kaplan-Meier and log-rank tests were computed to explore the data. The log-logistic inverse Gaussian shared frailty model was employed using a 95% CI, and variables with a p value < 0.05 were declared as determinants of recovery time.

RESULTS

Of 328 fistula patients, 293 (89.33%) were physically cured. The Kaplan-Meier result showed that the overall mean and median survival time of time to recovery from obstetric fistula patients at Mekelle Hamlin Fistula Center is 42 and 33 days, respectively. In a log-logistic inverse Gaussian shared frailty model analysis, extensive fistula size (AHR : 1.282; 95% CI = 1.175-1.388), secondary and above education level (AHR : 0.830; 95% CI = 0.693-0.967), rural residence (AHR : 1.357; 95% CI = 1.236-1.479), and physiotherapy use (AHR : 0.801, 95% CI = 0662-0.940, 95% CI = 1.175-1.388) were statistically significant predictors of recovery from obstetrics fistula.

CONCLUSION

Rural place of residence, home delivery, and large and extensive size of the fistula prolong the timing of healing from the obstetric fistula. However, having tall height, physiotherapy treatment, secondary and above-educated women, and RVF type of fistula has a short time of healing for obstetric fistula in Mekelle Hamlin Fistula Center. Therefore, we recommend that health professionals promote institutional delivery and physiotherapy, shorten the duration of catheterization, and manage urine incontinence. In addition, we recommend that the regional health bureau promotes female education and pregnancy after 18 years. The survival probability of patients with obstetric fistulas is better predicted by the log-logistic inverse Gaussian shared frailty model. Therefore, it would be good for future researchers to take this model into account.

Outcome of urethral reconstruction among vesico-vaginal fistula patients: a cross-sectional study

Background

Obstetric fistula (OF) complicated by urethral loss (UL) poses a challenge to both the fistula surgeon and obstetric fistula patient. The involvement of the urethra and urethral closure mechanism in OF is an important determinant of successful closure of fistula and restoration of urinary continence. OF with UL is often associated with unsuccessful repair outcome. We describe urethral reconstruction in genital tract fistula patients with UL and the outcomes of the repair.

Methods

Aim To review the clinical characteristics and outcome of vesico-vaginal fistula associated urethral loss following urethral reconstruction.

This was a descriptive cross-sectional study conducted at the University College Hospital, Ibadan, Nigeria. A 5-year prospective data of all vesico-vaginal fistula patients with urethral loss (2011–2016) were reviewed and analysed. Data collected include socio-demographic and obstetric characteristics; cause of the fistula; and fistula characteristics—type of fistula, number of previous repairs, urethral loss, outcome of repair and follow-up. Data were entered and analysed using IBM SPSS version 20.

Results

Urethral loss occurred in 23 (15.3%) out of 150 women with OF; these women had urethral reconstruction surgery. The commonest type of urethral loss encountered in this cohort was proximal urethral loss which was seen in 12 (52.2%) patients. The most common types of fistula seen with urethral loss were large vesico-vaginal fistula (34.8%) and mid-vaginal fistula (26.1%). More than half of the women (56.6%) had previous unsuccessful repair at other facilities before presentation. The fistula closure rate was high (82.6%) regardless of type of urethral loss. Among the women with successful closure of OF with UL, about 36.8% had urinary stress incontinence post-fistula repair.

Conclusion

Urethral loss appears to be a rare complication of obstetric fistula. Successful closure with stress incontinence was seen in a sizeable number of women with OF with UL. Preoperative assessment for determinant of post-repair incontinence and surgical repair by experienced surgeons will improve successful outcome of repair in women with obstetric fistula with UL.

Predictive value of classification systems and single fistula-related factors in surgical management of vesicovaginal fistula

AIMS

The aim of this study was to find the most clinically useful vesicovaginal fistula (VVF) classification system or single fistula-related factor, which would be helpful in determining the most proper management leading to successful treatment.

METHODS

Between 2018 and 2020, 30 patients were diagnosed with VVF and underwent the Latzko procedure. Nineteen patients, after previously failed surgery, were injected with platelet-rich-plasma (PRP) before a final attempt to close VVF. Patients with primary VVF were included into the surgery only group and patients with secondary VVF were included into PRP and surgery group. Each patient was classified according to 13 different classification systems.

RESULTS

Statistical evaluation revealed some significant differences between the patients who required PRP injection and repeated surgery, compared with patients who were successfully treated at first surgery but only with Lawson, Waaldijk, Arrowsmith, and Tafesse classifications. Patients who succeded with the fistula closure after the first surgical procedure had significantly higher body mass index (BMI) when compared with patients who required PRP injection prior surgical procedure (30.9 vs. 25.7, respectively; p < .05).

CONCLUSIONS

None of the classification systems allows to precisely predict VVF surgery outcome. There are several factors such as previous surgery, lack of urethral involvement, lack of circumferential defect which might suggest that PRP injection would help to preserve watertightness of the closure. The most important finding is that overweight is the most positive predicting demographic feature of surgical success. Thus we may conclude that Martius flap technique should be taken into consideration in patients with low BMI.

Best Practices in Robotic-assisted Repair of Vesicovaginal Fistula: A Consensus Report from the European Association of Urology Robotic Urology Section Scientific Working Group for Reconstructive Urology

CONTEXT

Surgical repair of a vesicovaginal fistula (VVF) has been described extensively in the literature for several decades. Advances in robotic repair have been adopted since 2005.

OBJECTIVE

A consensus review of existing data based on published case series, expert opinion, and a survey monkey.

EVIDENCE ACQUISITION

This document summarizes the consensus group meeting and survey monkey results convened by the European Association of Urology Robotic Urology Section (ERUS) relating to the robotic management of VVF.

EVIDENCE SYNTHESIS

Current data underline the successful robotic repair of supratrigonal nonobstetric VVF. The panel recommends preoperative marking of the fistula by a guidewire or ureteral catheter, and placement of a protective ureteral JJ stent. An extravesical robotic approach usually provides a good anatomic view for adequate and wide dissection of the vesicovaginal space, as well as bladder and vaginal mobilization. Careful sharp dissection of fistula edges should be performed. Tension-free closure of the bladder is of utmost importance. Tissue interposition seems to be beneficial. The success rate of published series often reaches near 100%. An indwelling bladder catheter should be placed for about 10 d postoperatively.

CONCLUSIONS

When considering robotic repair for VVF, it is essential to establish the size, number, location, and etiology of the VVF. Robotic assistance facilitates dissection of the vesicovaginal space, harvesting of a well-vascularized tissue flap, and a tension-free closure of the bladder with low morbidity for the patient being operated in the deep pelvis with delicate anatomical structures.

PATIENT SUMMARY

Robotic repair of a vesicovaginal fistula can be applied safely with an excellent success rate and very low morbidity. This confirms the use of robotic surgery for vesicovaginal fistula repair, which is recommended in a consensus by the European Association of Urology Robotic Section Scientific Working Group for reconstructive urology.

Rising trends in iatrogenic urogenital fistula: A new challenge

Objective

To analyze trends in iatrogenic urogenital fistula among patients admitted for fistula repair at the Pakistan Institute of Medical Sciences, Islamabad.

Methods

In this longitudinal study, all patients who presented for fistula repair between 2006 and 2018 were included in the study. Patient data were collected on age, parity, and type and etiology of fistula, which was classified as ischemic or iatrogenic.

Results

Of 634 fistula patients, 371 (58.5%) had iatrogenic fistula, while 263 (41.5%) patients developed ischemic fistula due to obstructed labor. Mean age of patients was 31.6 years. Yearly trends showed an increase in iatrogenic fistula from 43.2% in 2006–2008 to 71.4% in 2017–2018. The major etiological contributor to iatrogenic fistula was hysterectomy (52.5%), followed by cesarean hysterectomy (26.4%), and cesarean delivery (19.9%).

Conclusion

A rising trend in iatrogenic fistula was observed. This emphasizes the need for optimization of surgical approaches and surgical skills. Moreover, gynecologic surgeries should be restricted to authorized gynecologic surgeons.

A rising yearly trend in iatrogenic fistula was observed over a 12‐year period in Pakistan.

Predictors of Obstetric Fistula Repair Outcomes in Lubango, Angola

OBJECTIVE

Obstetric fistulas have a significant physical and social impact on many women in Angola. The majority of the population of this sub-Saharan African nation does not have access to high-quality obstetric care, and this is associated with a risk of prolonged labour and formation of obstetric fistulas. Fistulas are challenging to correct surgically and may require repeated operations. The objective of the study was to determine predictors of successful obstetric fistula repair.

METHODS

In this retrospective study, data from all recorded cases of fistula repair performed between July 2011 and December 2016 at the Centro Evangélico de Medicina do Lubango (CEML) hospital located in Lubango, Angola, were reviewed. Analysis of the data was carried out to determine factors affecting the success of fistula repair; parametric and non-parametric tests were used for group comparisons and logistic regression for outcome prediction (Canadian Task Force classification II-2).

RESULTS

A total of 407 operations were performed on 243 women. Of these, 224 women were diagnosed with a vesicovaginal fistula and 19 with a combined vesicovaginal and rectovaginal fistula. The success rate for the attempted repairs was 42%. On multivariate analysis, the success of first surgery was negatively affected by the difficulty of repair (odds ratio 0.28; P < 0.01). For patients requiring repeat surgery, the odds of success were increased with each subsequent operation (odds ratio 5.32; P < 0.01).

CONCLUSION

Although fistulas rated as difficult to repair had a higher likelihood of initial failure, successive attempts at repair increased the likelihood of a successful outcome.

Time to recovery from obstetric fistula and determinants in Gondar university teaching and referral hospital, northwest Ethiopia

BACKGROUND

Obstetric fistula is an abnormal connection between the vagina and rectum and/or bladder, which leads to continuous urinary or fecal incontinence. It is a serious problem in the world poorest countries, where most mothers give birth without any medical care. In most cases obstetric fistula is preventable and can be treated successfully, if it is carried out by a competent surgeon with a good follow-up of postoperative care. However, there remains to explore more on the duration of obstetric fistula recovery and determinant factors. The aim of this study was to estimate the average recovery time of obstetric fistula and to identify its determinants in Gondar University teaching and referral hospital, northwest Ethiopia.

METHOD

A retrospective follow up study was conducted at Gondar University teaching and referral hospital. A total of 612 fistula cases were included in the study and simple random sampling technique was applied to select the study subjects. Kaplan-Meier and log rank test were computed to explore the data. Weibull regression survival model with univariate frailty was done to identify the determinant factors of time to recovery.

RESULTS

Of 612 fistula patients, 539(88.07%) were recovered. The Average (median) recovery time was 5.14 (IQR = 3.14, 9.14) weeks. Using Antibiotic (AHR = 1.49, 95% CI = 1.11-2.01), having history of antenatal care (ANC) (AHR = 1.95, 95% CI = 1.39-2.73), being literate (AHR = 2.23, 95% CI = 1.62-3.06), duration of bladder catheterization (AHR = 0.93, CI = 0.90-0.95) and being multiparous (AHR = 1.51, 95% CI = 1.17-1.96) were a significant predictors of the rate of recovery. Also, underweight (AHR = 0.45, 95% CI = 0.30-0.68), overweight (AHR = 0.56, 95% CI = 0.41-0.76), being obese (AHR = 0.41, 95% CI = 0.21-0.80), having extensive fistula (AHR = 0.82, 95% CI = 0.73-0.91), large fistula (AHR = 0.42, 95% CI = 0.23-0.78), medium width (AHR = 0.62, 95% CI = 0.43-0.91) and large width (AHR = 0.42, 95% CI = 0.23-0.78) were statistically significant predictors of the rate of recovery from fistula patients.

CONCLUSION

The average recovery time from obstetric fistula patients was 5.14 weeks. Small Length and width of fistula, patients' educational status (literacy), antibiotic use, history of antenatal care visits, normal BMI, short period catheterization and being multiparous were the significant determinate variables which shorten the recovery time of obstetric fistula.

Panzi score as a parsimonious indicator of urogenital fistula severity derived from Goh and Waaldijk classifications

OBJECTIVE

To derive a comprehensive system that allows a single score to define relative fistula severity.

METHODS

The present observational study included women with urogenital fistula treated at the Panzi Hospital, Democratic Republic of Congo, or its outreach clinics across the Democratic Republic of Congo between September 1, 2013, and December 31, 2014. Fistula severity was assessed by Goh and Waaldijk classifications and surgical success was ascertained. Logistic regression was used to select fistula characteristics predictive of surgical failure, and to preliminarily verify the newly derived Panzi score.

RESULTS

Overall, 837 women were included in the analysis. Goh or Waaldijk fistula descriptors associated with a higher probability of poor surgical outcomes in the unadjusted bivariate analysis were circumferential defect (P=0.007), proximity to the external urethral orifice (P=0.001), and size (P=0.001). These fistula characteristics were used to construct the Panzi score, which varied from 3 (most severe) to 0 (minor fistula). For each increase above 0, the odds of surgical failure increase by a factor of 1.65 (P<0.001).

CONCLUSION

The Panzi score of urogenital fistula provided a data-driven, simple, comprehensive, and parsimonious score. It could be used to report group data, to provide continuous level data for use in higher order statistics, and to resolve issues such as the cut-off point for referring women to hospital in accordance with fistula complexity.

Systematic review of shorter versus longer duration of bladder catheterization after surgical repair of urinary obstetric fistula

BACKGROUND

Bladder catheterization duration after urinary obstetric fistula surgery varies widely.

OBJECTIVE

To assess the effect of bladder catheterization duration after urinary obstetric fistula surgery.

SEARCH STRATEGY

Medline, EMBASE, CINAHL, GIM, and POPLINE databases were searched, without language restrictions, using "obstetric urinary fistula" and "catheterization" from inception to September 30, 2017.

SELECTION CRITERIA

Randomized controlled trials comparing shorter versus longer (>10 days) bladder catheterization after urinary obstetric fistula repair were included.

DATA COLLECTION AND ANALYSIS

Data were extracted and meta-analyses were conducted. The GRADE system was used to assess evidence quality.

MAIN RESULTS

Two unblinded non-inferiority trials (684 patients combined) were included. There were no differences between shorter and longer bladder catheterization in the risk of fistula repair breakdown either before (relative risk [RR] 1.14; 95% confidence interval [CI] 0.49-2.64) or after (RR 1.64; 95% CI 0.81-3.31) hospital discharge. Similarly, urinary infection (RR 5.18; 95% CI 0.25-107.44); urinary incontinence before (RR 1.15; 95% CI 0.54-2.43) or after (RR 1.16; 95% CI 0.62-2.18) discharge; urinary retention (RR 1.34; 95% CI 0.79-2.27); or extended hospital stay (RR 9.33; 95% CI 0.51-172.41) were not associated with duration of catheterization. Evidence quality was low or moderate.

CONCLUSIONS

Shorter, compared to longer, bladder catheterization duration after urinary obstetric fistula surgery was not associated with significant outcome differences.

Effect of HIV infection on outcomes after surgical repair of genital fistula

OBJECTIVE

To compare outcomes following surgical repair of genital fistula among Nigerian women with or without HIV.

METHODS

A retrospective review was conducted of all genital fistula repair surgeries performed at Evangel Vesicovaginal Fistula Center in Jos, Nigeria, between January 1, 2004, and April 30, 2014. Patient characteristics, HIV status, genital fistula characteristics, and postoperative outcomes were assessed for between-group variance. The odds ratio (OR) and 95% confidence intervals (CIs) were the primary measures used for determining the association between HIV status and surgical outcomes.

RESULTS

Of the 3313 surgeries recorded, 201 (6.1%) were performed among patients with HIV infection. No statistically significant between-group differences were found for patient or fistula characteristics. By contrast, failed vesicovaginal failure (VVF) closure was significantly more common among women infected with HIV than among their HIV-negative counterparts (OR 0.629, 95% CI 0.443-0.894). No between-group differences in failure rates were found for ureterovaginal or rectovaginal fistulas.

CONCLUSION

Determining HIV status before surgery could aid prediction of outcomes among Nigerian women undergoing repair of VVF. Further studies are required to examine factors that might improve outcomes for women with HIV infection.

Identifying Patients With Vesicovaginal Fistula at High Risk of Urinary Incontinence After Surgery

OBJECTIVE

To develop a risk score to identify women with vesicovaginal fistula at high risk of residual urinary incontinence after surgical repair.

METHODS

We conducted a prospective cohort study among 401 women undergoing their first vesicovaginal fistula repair at a referral fistula repair center in Lilongwe, Malawi, between September 2011 and December 2014, who returned for follow-up within 120 days of surgery. We used logistic regression to develop a risk score to identify women with a high likelihood of residual urinary incontinence, defined as incontinence grade 2-5 within 120 days of vesicovaginal fistula repair, based on preoperative clinical and demographic characteristics (age, number of years with fistula, human immunodeficiency virus status, body mass index, previous repair surgery at an outside facility, revised Goh classification, Goh vesicovaginal fistula size, circumferential fistula, vaginal scaring, bladder size, and urethral length). The sensitivity, specificity, and positive and negative predictive values of the risk score at each cut point were assessed.

RESULTS

Overall, 11 (3%) women had unsuccessful fistula closure. Of those with successful fistula closure (n=372), 85 (23%) experienced residual incontinence. A risk score cut point of 20 had sensitivity of 82% (95% confidence interval [CI] 72-89%) and specificity 63% (95% CI 57-69%) to potentially identify women with residual incontinence. In our population, the positive predictive value for a risk score cut point of 20 or higher was 43% (95% CI 36-51%) and the negative predictive value was 91% (95% CI 86-94%). Forty-eight percent of our study population had a risk score 20 or greater and, therefore, would have been identified for further intervention.

CONCLUSION

A risk score of 20 or higher was associated with an increased likelihood of residual incontinence with satisfactory sensitivity and specificity. If validated in alternative settings, the risk score could be used to refer women with a high likelihood of postoperative incontinence to more experienced surgeons.

Parity as a predictor of obstetric fistula classification

INTRODUCTION AND HYPOTHESIS

Obstetric fistulas are injuries to the genital tract in women without emergency obstetric services. Parity may predict the characteristics of fistulas that affect closure success and residual incontinence. Circumferential fistulas may predispose patients to postoperative incontinence. We hypothesized that primiparous women have more distal fistulas than multiparous women, leading to more scarring and circumferential fistulas.

METHODS

A retrospective observational study was conducted on 1,856 women with obstetric fistula evaluated at three sites by three providers. Fistulas were classified using the Goh classification system. Women aged 10 to 55 years were classified as primiparas or multiparas. Analysis by parity of fistula type and size, degree of scarring, and presence of circumferential defect used the Chi squared or Fisher's exact test, and binary logistic regression.

RESULTS

Of the 1,841 (99.2 %) women included, 878 (47.7 %) were primiparas and 963 (52.3 %) were multiparas. Primiparas were more likely to have distal fistulas, type 4 being most common (31.5 %), whereas multiparas were more likely to have proximal fistulas, most commonly type 1 (48.1 %). Primiparas were more likely to have moderate to severe scarring (11.7 % vs 5.6 %; p < 0.001), and category III (57.1 % vs 39.2 %; p < 0.001), but not to develop circumferential fistulas (5.6 % vs 4.0 %; p = 0.127), be present for repeat surgery (7.1 % vs 7.6 %; p = 0.721), or have ureteric involvement (1.5 % vs 2.2 %; p = 0.301). Multivariate analyses confirmed increased risk with primiparity for distal fistula and scarring.

CONCLUSIONS

As hypothesized, primiparas were more likely to have distal fistulas and more scarring, but were not more likely to have circumferential fistulas. Surgeons should plan accordingly.

Factors associated with the failure of obstetric fistula repair in Guinea: implications for practice

Background

The prevention and treatment of obstetric fistula still remains a concern and a challenge in low income countries.

The objective of this study was to estimate the overall proportions of failure of fistula closure and incontinence among women undergoing repair for obstetric fistula in Guinea and identify its associated factors.

Methods

This was a retrospective cohort study using data extracted from medical records of fistula repairs between 1 January 2012 and 30 September 2013. The outcome was the failure of fistula closure and incontinence at hospital discharge evaluated by a dye test. A sub-sample of women with vesicovaginal fistula was used to identify the factors associated with these outcomes.

Results

Overall, 109 women out of 754 (14.5 %; 95 % CI:11.9–17.0) unsuccessful repaired fistula at discharge and 132 (17.5 %; 95 % CI:14.8–20.2) were not continent.

Failure of fistula closure was associated with vaginal delivery (AOR: 1.9; 95 % CI: 1.0–3.6), partially (AOR: 2.0; 95 % CI: 1.1–5.6) or totally damaged urethra (AOR: 5.9; 95 % CI: 2.9–12.3) and surgical repair at Jean Paul II Hospital (AOR: 2.5; 95 % CI: 1.2–4.9).

Women who had a partially damaged urethra (AOR: 2.5; 95 % CI: 1.5–4.4) or a totally damaged urethra (AOR: 6.3; 95 % CI: 3.0–13.0) were more likely to experience post-repair urinary incontinence than women who had their urethra intact.

Conclusion

At programmatic level in Guinea, caution should be paid to the repair of women who present with a damaged urethra and those who delivered vaginally as they carry greater risks of experiencing a failure of fistula closure and incontinence.

Pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa: Scoping Review

OBJECTIVE

To synthesise the evidence on pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa and to identify the existing knowledge gaps.

METHODS

A scoping review of studies reporting on pregnancy and childbirth in women who underwent repair for obstetric fistula in sub-Saharan Africa was conducted. We searched relevant articles published between 1 January 1970 and 31 March 2016, without methodological or language restrictions, in electronic databases, general Internet sources and grey literature.

RESULTS

A total of 16 studies were included in the narrative synthesis. The findings indicate that many women in sub-Saharan Africa still desire to become pregnant after the repair of their obstetric fistula. The overall proportion of pregnancies after repair estimated in 11 studies was 17.4% (ranging from 2.5% to 40%). Among the 459 deliveries for which the mode of delivery was reported, 208 women (45.3%) delivered by elective caesarean section (CS), 176 women (38.4%) by emergency CS and 75 women (16.3%) by vaginal delivery. Recurrence of fistula was a common maternal complication in included studies while abortions/miscarriage, stillbirths and neonatal deaths were frequent foetal consequences. Vaginal delivery and emergency C-section were associated with increased risk of stillbirth, recurrence of the fistula or even maternal death.

CONCLUSION

Women who get pregnant after repair of obstetric fistula carry a high risk for pregnancy complications. However, the current evidence does not provide precise estimates of the incidence of pregnancy and pregnancy outcomes post-repair. Therefore, studies clearly assessing these outcomes with the appropriate study designs are needed.

Quantifying uncertainty in intervention effectiveness with structured expert judgement: an application to obstetric fistula

OBJECTIVE

To demonstrate a new application of structured expert judgement to assess the effectiveness of surgery to correct obstetric fistula in a low-income setting. Intervention effectiveness is a major input of evidence-informed priority setting in healthcare, but information on intervention effectiveness is generally lacking. This is particularly problematic in the context of poorly resourced healthcare settings where even efficacious interventions fail to translate into improvements in health. The few intervention effectiveness studies related to obstetric fistula treatment focus on the experience of single facilities and do not consider the impact of multiple factors that may affect health outcomes.

DESIGN

We use the classical model of structured expert judgement, a method that has been used to quantify uncertainty in the areas of engineering and environmental risk assessment when data are unavailable. Under this method, experts quantify their uncertainty about rates of long-term disability in patients with fistula following treatment in different contexts, but the information content drawn from their responses is statistically conditioned on the accuracy and informativeness of their responses to a set of calibration questions. Through this method, we develop best estimates and uncertainty bounds for the rate of disability associated with each treatment scenario and setting.

PARTICIPANTS

Eight experts in obstetric fistula repair in low and middle income countries.

RESULTS

Estimates developed using performance weights were statistically superior to those involving a simple averaging of expert responses. The performance-weight decision maker's assessments are narrower for 9 of the 10 calibration questions and 21 of 23 variables of interest.

CONCLUSIONS

We find that structured expert judgement is a viable approach to investigating the effectiveness of medical interventions where randomised controlled trials are not possible. Understanding the effectiveness of surgery performed at different types of facilities can guide programme planning to increase access to fistula treatment.

Good clinical outcomes from a 7-year holistic programme of fistula repair in Guinea

Objectives

Female genital fistula remains a public health concern in developing countries. From January 2007 to September 2013, the Fistula Care project, managed by EngenderHealth in partnership with the Ministry of Health and supported by USAID, integrated fistula repair services in the maternity wards of general hospitals in Guinea. The objective of this article was to present and discuss the clinical outcomes of 7 years of work involving 2116 women repaired in three hospitals across the country.

Methods

This was a retrospective cohort study using data abstracted from medical records for fistula repairs conducted from 2007 to 2013. The study data were reviewed during the period April to August 2014.

Results

The majority of the 2116 women who underwent surgical repair had vesicovaginal fistula (n = 2045, 97%) and 3% had rectovaginal fistula or a combination of both. Overall 1748 (83%) had a closed fistula and were continent of urine immediately after surgery. At discharge, 1795 women (85%) had a closed fistula and 1680 (79%) were dry, meaning they no longer leaked urine and/or faeces. One hundred and fifteen (5%) remained with residual incontinence despite fistula closure. Follow-up at 3 months was completed by 1663 (79%) women of whom 1405 (84.5%) had their fistula closed and 80% were continent. Twenty-one per cent were lost to follow-up.

Conclusion

Routine programmatic repair for obstetric fistula in low resources settings can yield good outcomes. However, more efforts are needed to address loss to follow-up, sustain the results and prevent the occurrence and/or recurrence of fistula.

Objectifs

La fistule génitale féminine reste un problème de santé publique dans les pays en développement. De janvier 2007 à septembre 2013, le projet Fistula Care, géré par Engender Health en partenariat avec le Ministère de la Santé et soutenu par l’USAID, a intégré les services de réparation de fistules dans les maternités des hôpitaux généraux en Guinée. L'objectif de cet article est de présenter et de discuter les résultats cliniques de sept années de travail impliquant 2116 femmes traitées dans trois hôpitaux à travers le pays.

Méthodes

Il s'agit d'une étude de cohorte rétrospective utilisant des données extraites des dossiers médicaux de réparations de fistules menées de 2007 à 2013. Les données de l’étude ont été analysées au cours de la période allant d'avril à août 2014.

Résultats

La majorité des 2116 femmes qui ont subi une réparation chirurgicale avaient une fistule vésico vaginale (n = 2 045, 97%) et 3% avaient une fistule recto vaginale ou une combinaison des deux. Au total, 1748 (83%) femmes ont eu leur fistule refermée et sont devenues continentes d'urine immédiatement après la chirurgie. À la sortie, 1795 femmes (85%) avaient une fistule fermée et 1680 (79%) étaient sèches, c'est à dire qu'elles n'avaient plus de fuite d'urine et/ou de matières fécales. 115 (5%) femmes avaient toujours une incontinence résiduelle malgré la fermeture de la fistule. Le suivi à trois mois a été complété par 1663 (79%) femmes dont 1405 (84,5%) ont eu leur fistule fermée et 80% étaient continentes. 21% ont été perdues au suivi.

Conclusion

La réparation programmatique de routine de la fistule obstétricale dans les régions à faibles ressources peut donner de bons résultats. Toutefois, davantage d'efforts sont nécessaires pour remédier à la perte au suivi, maintenir les résultats et prévenir l'apparition et/ou la réapparition de fistules.

Objetivos

La fístula genital femenina continúa siendo una preocupación de salud pública en países en vías de desarrollo. Entre Enero 2007 y Septiembre 2013, el proyecto Fistula Care, manejado por EngenderHealth junto con el Ministerio de Salud de Guinea, y financiado por USAID, integró los servicios de reparación de fistula en las maternidades de hospitales generales en Guinea. El objetivo de este artículo es presentar y discutir los resultados clínicos de 7 años de trabajo con 2116 mujeres intervenidas en tres hospitales del país.

Métodos

Estudio retrospectivo de cohortes utilizando datos tomados de historias clínicas de reparaciones de fístula realizadas entre el 2007 y el 2013. Los datos del estudio se revisaron durante el periodo entre Abril y Agosto 2014.

Resultados

La mayoría de las 2116 mujeres que se sometieron a la reparación quirúrgica tenían una fistula vesico-vaginal (n = 2045, 97%) y 3% tenían una fístula recto-vaginal o una combinación de ambas. En general, 1748 (83%) tenían la fístula cerrada y eran continentes inmediatamente después de la cirugía. En el momento del alta, 1795 mujeres (85%) tenían la fistula cerrada y 1680 (79%) estaban secas, es decir que ya no perdían orina y/o heces. 115 (5%) continuaron teniendo incontinencia residual a pesar de que la fistula estaba cerrada. El seguimiento a los tres meses se completó para 1663 (79%) mujeres, de las cuales 1405 (84.5%) tenían la fistula cerrada y 80% eran continentes. Un 21% fueron perdidas durante el seguimiento.

Conclusión

La reparación rutinaria programada de la fístula obstétrica en lugares con pocos recursos puede dar buenos resultados. Sin embargo, se requieren más esfuerzos para resolver la pérdida durante el seguimiento, mantener los resultados y prevenir la aparición y/o reaparición de la fístula.

Charitable platforms in global surgery: a systematic review of their effectiveness, cost-effectiveness, sustainability, and role training

OBJECTIVE

This study was designed to propose a classification scheme for platforms of surgical delivery in low- and middle-income countries (LMICs) and to review the literature documenting their effectiveness, cost-effectiveness, sustainability, and role in training. Approximately 28 % of the global burden of disease is surgical. In LMICs, much of this burden is borne by a rapidly growing international charitable sector, in fragmented platforms ranging from short-term trips to specialized hospitals. Systematic reviews of these platforms, across regions and across disease conditions, have not been performed.

METHODS

A systematic review of MEDLINE and EMBASE databases was performed from 1960 to 2013. Inclusion and exclusion criteria were defined a priori. Bibliographies of retrieved studies were searched by hand. Of the 8,854 publications retrieved, 104 were included.

RESULTS

Surgery by international charitable organizations is delivered under two, specialized hospitals and temporary platforms. Among the latter, short-term surgical missions were the most common and appeared beneficial when no other option was available. Compared to other platforms, however, worse results and a lack of cost-effectiveness curtailed their role. Self-contained temporary platforms that did not rely on local infrastructure showed promise, based on very few studies. Specialized hospitals provided effective treatment and appeared sustainable; cost-effectiveness evidence was limited.

CONCLUSIONS

Because the charitable sector delivers surgery in vastly divergent ways, systematic review of these platforms has been difficult. This paper provides a framework from which to study these platforms for surgery in LMICs. Given the available evidence, self-contained temporary platforms and specialized surgical centers appear to provide more effective and cost-effective care than short-term surgical mission trips, except when no other delivery platform exists.

Clinical procedures and practices used in the perioperative treatment of female genital fistula during a prospective cohort study

Background

Treatment and care for female genital fistula have become increasingly available over the last decade in countries across Africa and South Asia. Before the International Federation of Gynaecology and Obstetrics (FIGO) and partners published a global fistula training manual in 2011 there was no internationally recognized, standardized training curriculum, including perioperative care. The community of fistula care practitioners and advocates lacks data about the prevalence of various perioperative clinical procedures and practices and their potential programmatic implications are lacking.

Methods

Data presented here are from a prospective cohort study conducted between September 2007 and September 2010 at 11 fistula repair facilities supported by Fistula Care in five countries. Clinical procedures and practices used in the routine perioperative management of over 1300 women are described.

Results

More than two dozen clinical procedures and practices were tabulated. Some of them were commonly used at all sites (e.g., vaginal route of repair, 95.3% of cases); others were rare (e.g., flaps/grafts, 3.4%) or varied widely depending on site (e.g. for women with urinary fistula, the inter-quartile range for median duration of post-repair bladder catheterization was 14 to 29 days).

Conclusions

These findings show a wide range of clinical procedures and practices with different program implications for safety, efficacy, and cost-effectiveness. The variability indicates the need for further research so as to strengthen the evidence base for fistula treatment in developing countries.

Sexual function after vaginal and abdominal fistula repair

OBJECTIVE

The purpose of this study was to compare clinical outcomes and sexual function between transvaginal and transabdominal repairs of vesicovaginal fistulae (VVF).

STUDY DESIGN

Participants (99 women with VVF at a tertiary referral center) were treated with urinary catheterization for 12 weeks and, if the procedure was unsuccessful, underwent repair using either the transvaginal (Latzko) or transabdominal technique. Objective clinical parameters were analyzed; subjective outcomes were recorded prospectively before surgery and at the 6-month follow-up examination with the use of the female sexual function index to evaluate sexual function and the visual analog scale to measure general disturbance by the fistula.

RESULTS

After bladder drainage for 12 weeks, 8 patients had spontaneous fistula closure. Demographic variables were similar in the transvaginal (n = 60) and transabdominal (n = 31) repair groups. The transvaginal procedure showed significantly shorter operation times, less blood loss, and shorter hospital stay. Continence rates 6 months after surgery were 82% (transvaginal) and 90% (transabdominal). Sexual function in the 64 sexually active patients was significantly improved, and overall disturbance by the fistula was reduced with both operative techniques. Neither surgical intervention was superior to the other regarding sexual function or visual analog scale.

CONCLUSION

Fistula repair improves sexual function and quality of life with no difference attributable to surgical route. Given this and that operating time, blood loss and length of stay are less with the transvaginal approach, the transvaginal approach is preferred in VVF repair if fistula and patient characteristics are suitable.

Outcomes in obstetric fistula care: a literature review

PURPOSE OF REVIEW

To highlight the lack of consistency in the terminology and indicators related to obstetric fistula care and to put forward a call for consensus.

RECENT FINDINGS

Recent studies show at least some degree of statistical correlation between outcome and the following clinical factors: degree of scarring/fibrosis, fistula location, fistula size, damage to the urethra, presence of circumferential fistula, bladder capacity, and prior attempt at fistula repair.

SUMMARY

Consensus about basic definitions of clinical success does not yet exist. Opinions vary widely about the prognostic parameters for success or failure. Commonly agreed upon definitions and outcome measures will help ensure that site reviews are accurate and conducted fairly. To properly compare technical innovations with existing methods, agreement must be reached on definitions of success. Standardized indicators for mortality and morbidity associated with fistula repair will improve the evidence base and contribute to quality of care.

Development and comparison of prognostic scoring systems for surgical closure of genitourinary fistula

OBJECTIVE

The purpose of this study was to test the diagnostic performance of 5 existing classification systems (developed by Lawson, Tafesse, Goh, Waaldijk, and the World Health Organization) and a prognostic scoring system that was derived empirically from our data to predict fistula closure 3 months after surgery.

STUDY DESIGN

Women with genitourinary fistula (n = 1274) who received surgical repair services at 11 health facilities in sub-Saharan Africa and Asia were enrolled in a prospective cohort study. Using one-half of the sample, we created multivariate generalized estimating equation models to obtain weighted prognostic scores for components of each existing classification system and the empirically derived scoring system. With the second one-half, we developed receiver operating characteristic curves using the prognostic scores and calculated areas under the curves (AUCs) and 95% confidence intervals (CIs) for each system.

RESULTS

Among existing systems, the scoring systems that represented the World Health Organization, Goh, and Tafesse classifications had the highest predictive accuracy: AUC, 0.63 (95% CI, 0.57-0.68); AUC, 0.62 (95% CI, 0.57-0.68), and AUC, 0.60 (95% CI, 0.55-0.65), respectively. The empirically derived prognostic score achieved similar predictive accuracy (AUC, 0.62; 95% CI, 0.56-0.67); it included significant predictors of closure that are found in the other classification systems, but contained fewer, nonoverlapping components. The differences in AUCs were not statistically significant.

CONCLUSION

The prognostic values of existing urinary fistula classification systems and the empirically derived score were poor to fair. Further evaluation of the validity and reliability of existing classification systems to predict fistula closure is warranted; consideration should be given to a prognostic score that is evidence-based, simple, and easy to use.

Determinants of postoperative outcomes of female genital fistula repair surgery

OBJECTIVE

To determine predictors of fistula repair outcomes 3 months postsurgery.

METHODS

We conducted a multicountry prospective cohort study between 2007 and 2010. Outcomes, measured 3 months postsurgery, included fistula closure and residual incontinence in women with a closed fistula. Potential predictors included patient and fistula characteristics and context of repair. Multivariable generalized estimating equation models were used to generate adjusted risk ratios (RRs) and 95% confidence intervals (CIs).

RESULTS

Women who returned for follow-up 3-month postsurgery were included in predictors of closure analyses (n=1,274). Small bladder size (adjusted RR 1.57, 95% CI 1.39-1.79), prior repair (adjusted RR 1.40, 95% CI 1.11-1.76), severe vaginal scarring (adjusted RR 1.56, 95% CI 1.20-2.04), partial urethral involvement (adjusted RR 1.36, 95% CI 1.11-1.66), and complete urethral destruction or circumferential defect (adjusted RR 1.72, 95% CI 1.33-2.23) predicted failed fistula closure. Women with a closed fistula at 3-month follow-up were included in predictors of residual incontinence analyses (n=1,041). Prior repair (adjusted RR 1.37, 95% CI 1.13-1.65), severe vaginal scarring (adjusted RR 1.35, 95% CI 1.10-1.67), partial urethral involvement (adjusted RR 1.78, 95% CI 1.27-2.48), and complete urethral destruction or circumferential defect (adjusted RR 2.06, 95% CI 1.51-2.81) were significantly associated with residual incontinence.

CONCLUSION

The prognosis for genital fistula closure is related to preoperative bladder size, previous repair, vaginal scarring, and urethral involvement.
