PLoS One 2024; 19:e0303020. [PMID: 38722847 PMCID: PMC11081269 DOI: 10.1371/journal.pone.0303020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 04/17/2024] [Indexed: 05/13/2024] Open
Abstract
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.

Abstract
INTRODUCTION In the Western world today, urogenital fistula, including vesicovaginal fistula (VVF), is rare. However, while it remains significant in developing parts of the world due to prolonged and obstructed labor, in this study, we systematically reviewed the existing literature, discussing VVF occurrence, its etiology, and outcomes. MATERIAL AND METHODS We used electronic databases to search relevant articles from 2010-2020. The screening was performed with the help of Covidence. Relevant data from included studies were extracted in excel sheets, and final analysis was done using CMA-3 using proportion with 95% confidence interval (CI). RESULTS Fifteen studies reported the VVF among the fistula series. The pooled result showed 76.57% cases of VVF (CI, 65.42-84.96), out of which 27.54% were trigonal, 55.70% supra-trigonal, and the rest with a varied description like circumferential, juxta-cervical, juxta-urethral. Obstetric etiology was commonly reported with 19.29% (CI, 13.26-27.21) with cesarean section and 31.14% (CI, 18.23-47.86) with obstructed labor. Hysterectomy was the commonly reported etiology among gynecological etiology (46.52%, CI; 36.17-57.19). Among different surgical treatments employed for fistula closure, 49.50% were by abdominal approach (CI, 37.23-61.82), and 42.31% by vaginal approach (CI, 31.82-53.54). Successful closure of fistula was reported in 87.09% of the surgeries (CI, 84.39-89.38). CONCLUSION The vesicovaginal fistula is the most common type of genitourinary fistula. Major causes of fistula are gynecological surgery, obstructed labor, and cesarean section. The vaginal approach and abdominal are common modalities of repair of fistula with favorable outcomes in the majority of the patients.

Nannyonga B, Singull M. Modelling allocation of resources in prevention and control of obstetric fistula in Ugandan women. PLoS One 2020; 15:e0238059. [PMID: 32911511 PMCID: PMC7482929 DOI: 10.1371/journal.pone.0238059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 08/07/2020] [Indexed: 11/18/2022] Open
Abstract
In spite of reliable and skilled healthcare resources, the prevalence rate of obstetric fistula in Uganda is high. The risk factors for obstetric fistula cut across due to high poverty rates and cultural barriers. The main objective of this study was to assess the impact of inability to access skilled healthcare at delivery and implications to the economy. The specific objective was to determine the best way of investment in getting women access to skilled healthcare before, during and after child birth. The question to be answered was whether it was more economical to invest in getting women access to skilled healthcare, or in expanding healthcare. The study was conducted using data from the Uganda Demographic Health Survey 2016. The data was from 18,506 women in the age group of 15-49 in 15 regions around the country. Results show that the highest investment in providing access to skilled healthcare is required when there are few skilled healthcare centres. On the other hand, if there is little investment in providing access to skilled healthcare during child birth, many skilled healthcare centres are required. Results show further that the minimum time taken to reduce fistula prevalence is attained when there are many women accessing skilled healthcare in the few equipped health centres. However, if there are many skilled healthcare centres but a few women treated for obstetric fistula, then it will take longer to reduce fistula prevalence. Fitting the model to data suggested that Uganda has a big backlog of women to treat for obstetric fistula as in all skilled healthcare centres, there were less women treated than expected. Although still under the expected figure, the benefit of these treatments for obstetric fistula is that for every one woman treated, 8 more would seek treatment for the condition. This would however cost the country a great deal in that the treatment funds would perhaps give more returns if diverted to outreach activities aimed to get women seek skilled healthcare during child birth.

Abstract
CONTEXT Urogenital fistula is a global healthcare problem, predominantly associated with obstetric complications in low-resourced countries and iatrogenic injury in well-resourced countries. Currently, the published evidence is of relatively low quality, mainly consisting retrospective case series. OBJECTIVE We evaluated the available evidence for aetiology, intervention, and outcomes of urogenital fistulae worldwide. EVIDENCE ACQUISITION We performed a systematic review of the PubMed and Scopus databases, classifying the evidence for fistula aetiology, repair techniques, and outcomes of surgery. Comparisons were made between fistulae treated in well-resourced countries and those in low-resourced countries. EVIDENCE SYNTHESIS Over a 35-yr period, 49 articles were identified using our search criteria, which were included in the qualitative analysis. In well-resourced countries, 1710/2055 (83.2%) of fistulae occurred following surgery, whereas in low-resourced countries, 9902/10398 (95.2%) were associated with childbirth. Spontaneous closure can occur in up to 15% of cases using catheter drainage and conservative approaches are more likely to be successful for nonradiotherapy fistulae. Of patients undergoing repairs in well-resourced countries, the median overall closure rate was 94.6%, while in low-resourced countries, this was 87.0%. Closure was significantly more likely to be achieved using a transvaginal approach then a transabdominal technique (90.8% success vs 83.9%, Fisher's exact test; p=0.0176). CONCLUSIONS It is difficult to conclude whether any specific route of surgery has advantage over any other, given the selection of patients to a particular procedure is based upon individual fistula characteristics. However, surgical repair should be carried out by experienced fistula surgeons, well versed in all techniques as the primary attempt at repair is likely to be the most successful. PATIENT SUMMARY Urogenital fistulae are a common problem worldwide; however, the available evidence on fistula management is poor in quality. We searched the current literature and identified that 95% of fistulae occur following childbirth in low-resourced countries, whereas 80% of fistulae are associated with surgery in well-resourced countries, where successful repair is also more likely to be achieved. The first attempt at repair is often the most successful and therefore fistula surgery should be centralised to hospitals with the most experience.

BMC Pregnancy Childbirth 2016; 16:2. [PMID: 26732574 PMCID: PMC4702356 DOI: 10.1186/s12884-015-0755-1] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2015] [Accepted: 11/21/2015] [Indexed: 11/10/2022] Open
Abstract
Background Obstetric fistula affects a woman’s life physically, psychosocially, and economically. Although surgery can repair the physical damage of fistula, the devastating consequences that affect a woman’s quality of life may persist when she reintegrates into her community. This qualitative study assessed long-term outcomes among women who underwent obstetric fistula repair in Malawi. We explored three domains: overall quality of life before and after repair, fertility and pregnancy outcomes after repair, and understanding of fistula. Methods In-depth interviews were conducted in Chichewa with 20 women from seven districts across Central Malawi. All women were interviewed 1 to 2 years after surgical repair for obstetric fistula at the Fistula Care Centre in Lilongwe, Malawi. Interviews were independently coded and analyzed using content analysis. Results About half of women were married and nine of 20 women reported some degree of urinary incontinence. With the exception of relationship challenges, women’s concerns before and after repair were different. Additionally, repair had resolved many of the concerns women had before repair. However, challenges, both directly and indirectly related to fistula, persisted. Improvements in quality of life at the individual level included feelings of freedom, confidence and personal growth, and improved income-earning ability. Interpersonal quality of life improvements included improved relationships with family and friends, reduced stigma, and increased participation with their communities. Nearly half of women desired future pregnancies, but many were uncertain about their ability to bear children and feared additional pregnancies could cause fistula recurrence. Most women were well informed about fistula development but myths about witchcraft and fear of delivery were present. Nearly all women would recommend fistula repair to other women, and many were advocates in their communities. Conclusions Nearly all women believed their quality of life had improved at the individual and interpersonal levels since fistula repair, even among women who continued to have urinary incontinence. Contrary to other studies, women reported they were welcomed back by their communities and had limited challenges when reintegrating. Despite the overall improvements in quality of life, many continued to have relationship problems and were concerned about future fertility. These issues need to be further explored in other studies.

Abstract
BACKGROUND The purpose of the study was to analyze the incidence, causes, and management of vesicovaginal fistula (VVF) in adolescent girls. CASES Three girls of adolescent age were diagnosed with VVF, caused by a vaginal foreign body (ie, an aerosol spray cap). Transvesical reconstruction was performed in 2 cases. After the diagnosis of VVF, the third girl was discharged home with Foley catheter drainage. Three months later, she presented with pregnancy and was lost to follow-up. SUMMARY AND CONCLUSION Evaluation of unusual urinary symptoms in an adolescent should include vaginal examination and/or imaging. Aerosol spray caps remain the most common vaginal foreign body resulting in VVFs in adolescent girls in Lithuania. Transvesical reconstruction is safe and efficient.

Abstract
PURPOSE OF REVIEW To review current literature on the management of genitourinary fistulae, specifically, the techniques for diagnosis, timing to repair, surgical approach and recent advancements in surgical technique. RECENT FINDINGS Recent advancement in minimally invasive surgery has prompted surgeons to perform fistula repairs with laparoscopic or robotic-assisted laparoscopic techniques. Whereas there is a role for transabdominal fistula closure, the majority of fistulae are still best approached via a transvaginal route. SUMMARY Genitourinary fistulae from obstetric trauma have received increased attention and funding to treat and prevent this devastating condition in developing countries. Despite multiple classification systems, a standardized classification that accurately identifies predictors of successful repair is lacking. In industrialized nations, genitourinary fistulae are rare and are most frequently associated with pelvic surgery, pelvic radiation, cancer or trauma. Surgical techniques to repair these fistulae have shifted from transabdominal laparotomy to minimally invasive laparoscopic procedures. Vascularized tissue flaps can play an important role in successful closure of complex fistulae. Despite advancements in surgical technology, overarching principles of fistula closure remain. The majority of fistulae can be closed through a transvaginal approach, with a tension-free, watertight, multilayer closure.

Abstract
Background Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. Methods A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. Results The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. Conclusion Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.
