Supporting Women after Obstetric Fistula Surgery to Enhance Their Social Participation and Inclusion

Obstetric fistula is a childbirth complication causing abnormal openings between the urinary, bowel, and genital tracts, leading to involuntary leakage and potential long-term disability. Even after surgical repair, women continue to face psychological and social challenges that affect their social inclusion and participation. This study explored family and service provider perspectives on current support systems and identified gaps affecting women's inclusion and participation post-fistula surgery. Building on a prior study of women who underwent obstetric fistula surgical repair, we qualitatively examined available formal and informal post-surgical supports in Ethiopia. We conducted 20 interviews with family members and service providers and analyzed them using Charmaz's grounded theory inductive analysis approach. We identified four themes that indicated the available formal support in fistula care, the impact of formal support on women's social participation and inclusion, the gaps in formal support systems, and post-surgery informal supports and their challenges. Both groups believed support needs for women after surgery remain unmet, highlighting the need to strengthen holistic support services to improve women's social inclusion and participation. This study contributes to limited research on formal and informal support for women, emphasizing the need for enhanced economic, psychological, and sexual health-related support post-obstetric fistula surgery.

Uretero-uterine fistula following Manual Vacuum Aspiration for Incomplete abortion: A rare case report

Genitourinary fistulas are a well-recognized complication of various gynecological, obstetrical, and endourological interventions. The incidence of uretero-uterine fistula is very rare compared to other genitourinary fistulas. Few cases are reported in literature regarding the uretero- uterine fistula following manual vacuum aspiration of retained product of placenta. We report a case of 28 year multi-parous women who had presented with complain of involuntary passage of urine following manual vacuum aspiration for retained product of conception. Common tests for suspicion of uretero-uterine fistula include cystoscopy, triple swab test, and CT urography. Our patient was diagnosed in CT urography and was managed by exploratory laparotomy with end-to-end anastomosis of the right ureter, DJ stenting, and repair of a uterine perforation. Due to relatively rare incidence of this condition, there has not been a specific guideline for management. A multimodality and multidisciplinary approach have been proposed for the management of uretero-uterine fistulas.

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.

Interventions for treating obstetric fistula: An evidence gap map

Obstetric fistula is prevalent in low- and middle-income countries, with between 50,000 and 100,000 new cases each year. The World Health Organization aims to eradicate it by 2030 but a clear idea of the extant evidence is unavailable. This evidence map compiled evidence on treatments for obstetric fistula to identify potential knowledge gaps. The protocol for this work was published on the Open Science Framework (DOI: 10.17605/OSF.IO/H7J35). A survey was developed, piloted and distributed online through organisations with an interest in obstetric fistula and snowballing. Results informed the evidence map framework. Searches were run on MEDLINE, Embase, CENTRAL, Global Index Medicus and ScanMedicine on 16 February 2022 to identify potentially eligible systematic reviews, randomised controlled trials, cohort studies and case-control studies. Forward and backward citation chaining was undertaken on relevant systematic reviews and included studies. Studies were screened, coded and assessed for risk of bias by a single reviewer, with a second checking a proportion. The evidence map results were compared to survey results. Thirty-nine people responded to the survey, half of which were clinicians. Of 9796 records identified, 37 reports of 28 studies were included in the evidence map. Many included studies were at some risk of bias; for observational studies, this was predominantly due to lack of controlling for confounders. Most studies (71%) assessed surgical interventions alone. Reporting on other intervention types was limited. Regarding outcome measures most important to survey respondents, 24 studies reported on cure/improvement in obstetric fistula and 20 on cure/improvement in urinary incontinence. Reporting on quality of life, faecal incontinence and sexual function was limited. There is currently little robust evidence to guide patients and practitioners on the most effective treatment option for obstetric fistula. Further research is required to address evidence gaps identified.

An International Continence Society (ICS)/ International Urogynecological Association (IUGA) joint report on the terminology for the assessment and management of obstetric pelvic floor disorders

AIMS

The terminology of obstetric pelvic floor disorders should be defined and reported as part of a wider clinically oriented consensus.

METHODS

This Report combines the input of members of two International Organizations, the International Continence Society (ICS) and the International Urogynecological Association (IUGA). The process was supported by external referees. Appropriate clinical categories and a sub-classification were developed to give coding to definitions. An extensive process of 12 main rounds of internal and 2 rounds of external review was involved to exhaustively examine each definition, with decision-making by consensus.

RESULTS

A terminology report for obstetric pelvic floor disorders, encompassing 357 separate definitions, has been developed. It is clinically-based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it usable by different specialty groups and disciplines involved in the study and management of pregnancy, childbirth and female pelvic floor disorders. Clinical assessment, investigations, diagnosis, conservative and surgical treatments are major components. Illustrations have been included to supplement and clarify the text. Emerging concepts, in use in the literature and offering further research potential but requiring further validation, have been included as an Appendix. As with similar reports, interval (5-10 year) review is anticipated to maintain relevance of the document and ensure it remains as widely applicable as possible.

CONCLUSION

A consensus-based Terminology Report for obstetric pelvic floor disorders has been produced to support clinical practice and research.

Same problem, different approaches: transvesical and extravesical laparoscopic vesicovaginal fistula repair-case report

Vesicovaginal fistulas (VVaFs) are relatively uncommon in developed countries but with devastating consequences for the women suffering them. Conservative management has a low response rate. The surgical repair is a technically demanding procedure. Transvaginal, open transabdominal or laparoscopic (pure or robot-assisted) approaches have been described with similar post-operative results. We report two real-life cases of VVaF after surgery of benign gynaecological conditions, both presenting with continuous urinary incontinence and repaired with laparoscopic surgery. The first case had a simple tract above the trigone and was managed with an extravesical approach. The second is a complex case with multiple fistulous tracts that required a transabdominal-transvesical approach (modified O’Connor technique). Both patients have their fistula closed and are continent after surgery with a mean follow-up of 9 months. Given the lack on evidence for the selection of the best approach, it is important to report the outcomes with the different surgical techniques in both simple and complex fistulae. A pre-operative exhaustive study of the location and number of fistulous tracts is essential, as well as selecting the technique which best allows tissue dissection and tension-free suture to get a successful closure. Therefore, knowledge of several procedures and approaches is mandatory when dealing with this disorder.

A retrospective case series on transvaginal repair of rectovaginal fistula performed by a urogynaecology operative team in Australia

BACKGROUND

Rectovaginal fistula (RVF) is an abnormal epithelialised connection between the rectum and vagina. It is a common condition in limited resource settings and is caused almost exclusively by obstetric injury. In contrast, RVF is uncommonly seen in high resource settings.

AIMS

This study aims to review the aetiology and effectiveness of RVF management in the high resource setting, identifying predictors for repair success and long-term outcomes.

MATERIALS AND METHODS

A retrospective case series study of patients who underwent transvaginal RVF repairs at two secondary healthcare facilities over a 14-year period by one operative group.

RESULTS

A total of 41 patients underwent 46 surgical repairs. All patients presented with flatal and/or faecal incontinence and aetiology was identifiable in 78.0% (n = 32). Obstetric cause was implicated in 26.8% (n = 11) and other causes include 26.8% (n = 11) from vaginal and abdominal surgery, 14.6% (n = 6) from perianal abscess, 7.32% (n = 3) as complications of Crohn's disease and 2.44% (n = 1) as a complication of a cube pessary. Fistula was cured in 38 of 41 cases (92.7%) with a primary repair closure rate of 80.5% (n = 33). Post-operative symptoms were limited to flatal incontinence in 4.88% (n = 2), faecal incontinence in 2.44% (n = 1), and persistent perineal pain in 7.32% (n = 3). The success of the surgical repair was not significantly impacted by fistula size, aetiology, presence of a stoma for diversion, history of prior repair, duration since RVF formation or repair technique.

CONCLUSIONS

This review identifies aetiology for RVF in the high resource setting and highlights the role of earlier surgical repair to minimise patient morbidity with good success in closure and reduction of post-operative symptoms.

Risk factors for perioperative blood transfusions after urogenital fistula repair in Uganda: a retrospective cohort study

OBJECTIVE

To determine the incidence of and risk factors for perioperative blood transfusions after urogenital fistula repairs in Uganda.

DESIGN

A retrospective cohort study.

SETTING

A community hospital in Masaka, Uganda.

POPULATION

Women who underwent fistula repair at the Kitovu Hospital between 2013 and 2019.

METHODS

Retrospective review of demographics and clinical perioperative characteristics of patients surgically treated for urogenital fistula. Patient characteristics were compared between those who did and those who did not require a blood transfusion.

MAIN OUTCOME MEASURES

Need for perioperative blood transfusion and risk factors.

RESULTS

A total of 546 patients treated for urogenital fistulas were included in this study. The median age was 31.1 ± 13.2 years. A vaginal surgical approach was used in the majority of patients (84.6%). Complications occurred in 3.5% of surgical repairs, and the incidence of blood transfusions was 6.2%. In multivariable analyses, for each gram per deciliter (g/dl) increase in preoperative haemoglobin, the odds of blood transfusion decreased by approximately 28% (adjusted OR 0.72, 95% CI 0.59-0.86). Women who had their fistula repaired abdominally were 3.4 times more likely to require transfusions (95% CI 1.40-8.08).

CONCLUSIONS

The incidence of blood transfusions among urogenital fistula repairs in our population is twice that of developed nations. An abdominal surgical approach to urogenital fistula is a significant risk factor for perioperative blood transfusions. The timing of the repair may warrant further study.

TWEETABLE ABSTRACT

One of the first studies to look at blood transfusion risk factors after fistula repair in a low-resource setting.

Rehabilitative care practices in the management of childbirth-related pelvic fistula: A systematic review

INTRODUCTION AND HYPOTHESIS

Childbirth-related pelvic fistula (CRF) often requires surgery, yet even with successful repair, mental health conditions, musculoskeletal impairments, urinary and fecal incontinence and sexual dysfunction persist for many women. Postoperative rehabilitation, (i.e., physiotherapy, mental health counseling) may address these concerns and has been reported for this population. This review aims to summarize the literature and level of evidence of rehabilitative care practices in fistula care to inform clinical practice, research and policy recommendations.

METHODS

A systematic literature review was conducted using Africa-Wide Information, CINAHL, Cochrane, Embase, Global Health, PAIS Index, PubMed and SCOPUS searching keywords and MeSH terms to identify women with CRF admitted for surgery. Two researchers progressively screened titles, abstracts and full-text articles. Eligible articles were classified primary if intervention details and outcomes were reported or secondary if rehabilitation was described, but no specific outcomes reported. Relevant study details, strengths and limitations, and key findings were extracted.

RESULTS

Eighteen articles were included: eight primary, ten secondary. Primary articles reported on urethral plugs for postoperative urinary incontinence (UI) (2/8), menstrual cup to manage UI (1/8), physiotherapy and health education (3/8) and mental health counseling (2/8). Secondary articles describe rehabilitation components in the context of program descriptions, qualitative analyses or reviews. All evidence was low or very low quality.

CONCLUSIONS

Research on rehabilitative care is very limited and highlights inconsistencies in practice. This review provides support for the feasibility of rehabilitation and establishes the need for future interventional studies that involve a comparator and reliable outcome measures.

Surgical repair and follow-up of chronic 4th degree obstetric perineal tear (total perineal defect) in 2 centres in eastern Africa

Introduction and hypothesis

Fourth-degree perineal tear occurs in up to 0.2% of vaginal deliveries. In limited resource communities, women often deliver in local villages without facilities to repair obstetric anal sphincter injuries. These fourth-degree tears heal by secondary intention and result in total perineal defects. The aim of the study is to present medium-term follow-up of a large number of women following repair of chronic fourth-degree tear.

Methods

Repairs of chronic obstetric fourth-degree tears were undertaken during surgical camps at Kagando Hospital, Uganda and Selian Hospital, Tanzania, from December 2013 to October 2019. Women completed Cleveland Clinic Incontinence Scores (CCIS) on admission (face to face) and during the 7-year follow-up period (via telephone).

Results

Two hundred fourteen women had medical history and CCIS completed on admission. The mean age at presentation was 33.9 years and mean duration of the condition was 8.9 years. Over a third of women stated they suffered social abandonment because of the unrepaired fourth-degree tear. Nearly 45% of women suffered the tear during the first vaginal delivery. At 1-year follow-up, 87% of 101 women scored 0 (perfect continence) and 94% of 66 women had perfect continence at 2 years. Forty-one births occurred during the follow-up period (32 vaginal deliveries) with two recurrences of fourth-degree tear.

Conclusions

Follow-up in limited resource communities is challenging. Short- to medium-term results of women who had repair of total perineal defect (unrepaired fourth-degree obstetric tears) are encouraging.

Function and disability status among women with fistula using WHODAS2.0: A descriptive study from Rwanda and Democratic Republic of Congo

OBJECTIVE

To assess function and disability among women in Rwanda and Democratic Republic of Congo living with fistula and identify characteristics associated with higher disability scores.

METHODS

Women presenting for fistula care were recruited. Eligible participants underwent a physical examination to classify fistula type and completed the WHO Disability Assessment Schedule 2.0 questionnaire to ascertain the impact of fistula on function across six domains: cognition, mobility, self-care, getting along, life activities, and participation. Disability scores were calculated (where 0 = no disability and 100 = complete disability). Participants were grouped according to no, low, or high disability status; results were examined to determine the domains most affected.

RESULTS

Among 69 participants, fistula type included: vesicovaginal (59.4%), ureterovaginal (14.5%), total absence of proximal urethra (11.6%), and rectovaginal (14.5%). Median disability score was 43.0/100 (interquartile range 26.0-67.0); 83% exhibited high disability status. Life activities and participation in society domains were most affected. Women with rectovaginal fistula reported the lowest scores, and those with total absence of proximal urethra reported the highest scores.

CONCLUSION

WHO Disability Assessment Schedule 2.0 represents a simple, robust measure of global disability status, aligns with research efforts to estimate maternal disability, and may inform health needs and resource allocation for this population. In this study, disability was common, varied by fistula type, and affected physical, mental, and social domains.

Traumatic deficient perineum: surgical management and outcome from a single center

INTRODUCTION AND HYPOTHESIS

Deficient perineum is a disruption of the perineal body and distal rectovaginal septum presenting with anal incontinence and a range of urogenital symptoms. There is scarce reported outcome of this condition with management often delayed and with a variety of surgical alternatives. This study aims to determine faecal continence outcomes after long-term surgical repair.

METHODS

Patients were included for analysis after surgical repair between 1989 and 2012. Cases were preoperatively assessed by endosonography and anorectal manometry with a record of their continence with the Cleveland Clinic Incontinence Score (CCIS). Surgical repair comprised an overlapping repair of the external anal sphincter (EAS) with levatorplasty. There was selective use of internal anal sphincter (IAS) suture and/or advancement perineoplasty for soft tissue reconstruction. Patients were clinically evaluated for functional outcomes with comparison of their postoperative CCIS.

RESULTS

There were 20 patients (median age 55.5 years; range 29-81 years) with a median duration of incontinence symptoms of 174 (range 1-540) months. All patients had an EAS and IAS defect with 14 (70%) undergoing an IAS suture and 10 (50%) a Corman-style anoplasty. Over a median follow-up of 137.2 (range 13-322) months, there was a significant decrease in the recorded median preoperative vs. postoperative CCIS 18, range 13-20 vs. 2, range 0-10, respectively; p < 0.001) with 18 (90%) satisfied with the functional outcome. Faecal diversion was not used in any of the patients.

CONCLUSIONS

Experienced delayed repair of a traumatic cloaca is associated with an acceptable functional outcome at medium- to long-term follow-up.

Characteristics of Obstetric and Iatrogenic Urogenital Fistulas in Burkina Faso: A Cross-Sectional Study

Objective

To compare the sociodemographic, clinical, and therapeutic characteristics of obstetric urogenital fistulas (OF) and iatrogenic urogenital fistulas (IF) treated in seven centers in Burkina Faso. Material and Methods. We carried out a cross-sectional study over a seven years' period (January 1, 2010 to December 31, 2016). We considered as iatrogenic all urogenital fistulas (UGF) occurred after elective caesarean section, gynecologic surgery (hysterectomy, myomectomy, and prolapse repair), or induced abortion. UGF following vaginal delivery after prolonged labor without obstetric maneuvers or caesarean section were considered as obstetric. UGF caused by other mechanisms (emergency caesarian section, congenital, and traumatic) were excluded from this study. The statistical analysis was carried out using version 14 of the STATA software. A logistic regression model was used to compare the two groups.

Results

310 cases of UGF were included. IF accounted for 25.8% (n = 80) versus 74.2% (n = 230) for OF. The median age was 35 years for IF and 35.38 years for OF. The vesicovaginal fistulas were predominant (74.5%) in the two groups. All circumferential fistulas were found in the OF group. OF were frequently associated with residence in rural areas (OR = 1.8; CI = [1.05–3.1]), low level of education (OR = 5.4; CI = [2.3–12.9]), and a height under 158 cm (OR = 3.4 CI = [1.7–6.6]). Vaginal sclerosis was less common among IF (OR = 2.2; CI = [1–4.6]). The failure of surgical treatment after 3 months was more associated with OF (OR = 4.7; CI = [1.1–20.5]).

Conclusion

OF were the most common, frequently affecting short women living in rural area and with low level of schooling. Fistulas were also more severe in the OF group. IF gave better results after surgical repair.
