Epidemiological, anatomoclinical, and therapeutic profile of obstetric fistula in the Democratic Republic of the Congo: About 1267 patients.

OBJECTIVE: Our aim is to describe the epidemiological, anatomoclinical and therapeutic profile of obstetric fistula (OF) in the Democratic Republic of the Congo (DRC). METHODOLOGY: This was a descriptive retrospective study that collected 1416 obstetric fistulas in 1267 patients in seven provinces of the DRC, treated between January 2017 and December 2022. The variables studied were epidemiological, anatomoclinical and therapeutic. RESULTS: The mean age of patients at the time of surgical repair was 33.2 years (range: 15 and 77 years) and 32.8% of patients were aged between 20 and 29 years. The mean age of the fistula at repair was 10 years (range: 3.5 months and 56 years). At the time of fistula, 61.7% of patients had delivered vaginally and 28.7% by caesarean section and 8.2% of patients had a haemostasis hysterectomy. Labour lasted at least 3 days in 47.3% of these patients for the fistula birth. Deliveries took place either at home (27.4%) or in a health facility (72.6%); 83.6% of newborns resulting from these births had died. Taken as a whole, urogenital fistulas are more common than genito-digestive fistulas. Urethro-vaginal (26.2%) and vesico-uterine (24.7%) anatomoclinical entities were predominant among urogenital fistulas. A total of 1416 fistulas were surgically repaired in 1267 patients. These repairs were successful for 1226 (86.6%) fistulas. The main surgical route used was transvaginal (68.8%). CONCLUSION: In the DRC, obstetric fistula is common in young adult women. It often results from vaginal delivery, after prolonged labour. Fistula births often result in the death of newborns. Uro-genital obstetric fistulas are the most frequent with predominance of urethro-vaginal and vesico-uterine anatomoclinical entities. Fistulas remain untreated for a long time. Mostly done transvaginally, surgical repair gives a good result.

Prevalence and repair patterns of vesicovaginal fistula: a large retrospective population-based cohort analysis.

PURPOSE: Vesicovaginal fistulae (VVF) have a significant negative impact on quality of life, with failed surgical repair resulting in ongoing morbidity. Our aim was to characterize the rate of VVF repair and repair failures over time, and to identify predictors of repair failure. METHODS: We completed a population-based, retrospective cohort study of all women who underwent VVF repair in Ontario, Canada, aged 18 and older between 2005 and 2018. Risk factors for repair failure were identified using multivariable cox proportional hazard analysis; interrupted time series analysis was used to determine change in VVF repair rate over time. RESULTS: 814 patients underwent VVF repair. Of these, 117 required a second repair (14%). Mean age at surgery was 52 years (SD 15). Most patients had undergone prior gynecological surgery (68%), and 76% were due to iatrogenic injury. Most repairs were performed by urologists (60%). Predictors of VVF re-repair included iatrogenic injury etiology (HR 2.1, 95% CI 1.3-3.45, p = 0.009), and endoscopic repair (HR 6.1, 95% CI 3.1-11.1, p < 0.05,); protective factors included combined intra-abdominal/trans-vaginal repair (HR 0.51, 95% CI 0.3-0.8, p = 0.009), and surgeon years in practice (21 + years-HR 0.5, 95% CI 0.3-0.9, p = 0.005). Age adjusted annual rate of VVF repair (ranging from 0.8 to 1.58 per 100,000 women) and re-repair did not change over time. CONCLUSIONS: VVF repair and re-repair rates remained constant between 2005 and 2018. Iatrogenic injury and endoscopic repair predicted repair failure; combined intra-abdominal/trans-vaginal repair, and surgeon years in practice were protective. This suggests surgeon experience may protect against VVF repair failure.

Genitourinary Fistula: 5 Years' Experience of Five Referral Centers in Iran.

INTRODUCTION AND HYPOTHESIS: Genitourinary fistula is a devastating ailment that has an impact on women's physical health, mental health, emotional health, and financial security. The management of genitourinary fistula depends on the type, size, and duration of fistula formation. The purpose of this study is to report the features of genitourinary fistula in Iranian women and our experience in the management of fistula. METHODS: Retrospective chart reviews of 283 patients were performed to determine the cause of the fistula, prior repairs, tissue interposition, and the success rate. The operation was considered successful if the patient did not have any urine leakage during the observation time. RESULTS: The mean (SD) age of women was 49.51 (19.39; range: 21-70) years, Of these, 137 (52.9%) had a history of previous genitourinary fistula surgery. The average fistula was 1.53 (0.041) cm in size. The median (interquartile range) operation lasted 70 (15) min. The success rate after fistula repair was 91.5%. The typical follow-up period lasted 13.26 (range: 1-88) months. Forty-three (15.2%) patients had a big fistula (>2.5 cm) and 4 patients (1.4%) had a history of pelvic radiation therapy, among other reasons for failure. After a second repair, all patients' initial failures were resolved. There were no significant complications, as classified by Clavien-Dindo class 2 or greater. Additionally, there were no bowel, ureteral, or nerve injuries. CONCLUSIONS: Our patients with genitourinary fistula had a successful outcome following repair techniques, without any significant morbidity or mortality.

Obstetric vesico-uterine fistula in nine reference hospitals in the Democratic Republic of the Congo: epidemiological, clinical, and therapeutic aspects.

INTRODUCTION: With global cesarean section rates rising, there's concern about increase in obstetric vesico-uterine fistula (OVUF). Very little is known about this anatomoclinical entity of obstetric fistula in Africa in general and in DRC in particular. Our purpose was to describe the epidemiological, clinical, and therapeutic aspects of OVUF in the Democratic Republic of the Congo (DRC). METHODS: This was a descriptive cross-sectional study. Data were collected from patients who presented with OVUF across seven provinces of the DRC (North Kivu, Haut-Uélé, Kasai Central, Kwilu, Maniema, Nord-Ubangi and Sankuru) from January 2017 to December 2022. Study variables were epidemiological, clinical, and therapeutic features. RESULTS: Of 1,267 patients presenting with obstetric fistulas, 355 (28.0%) had OVUF. The mean age was 32.9 ± 11.6 years, 80.6% of patients (286/355) lived in rural areas, and the majority had a low level of education (40% no formal education, 30.1% primary school, 28.7% secondary school). In total, 64.8% of patients were primiparous (230/355) and in all (100%) cases, OVUF was caused iatrogenically during cesarean delivery. Majority (76.3%) of patients laboured for one day or less (mean duration 1.0 ± 0.5 days) before giving birth, and the fetus died in 58.3% of cases. In 35.8% of cases, the fistula had lasted more than 10 years (mean age 10.1 ± 10.0 years) before repair. A proportion of 88.2% (n = 313) of OVUF was isolated while 11.3% (n = 40) was associated with a uretero-vaginal fistula. In 82.8% (n = 294) of cases the OVUF was single. The average fistula size was 2.4 ± 1.0 cm (range: 0.5 and 5.5 cm) and 274 (77.2%) fistulas measured between 1.5 and 3 cm, with 14.9% (n = 53) of them larger than 3 cm. Fibrosis was present in 65.1% of cases, cervical involvement was absent in 97.7% and post-operative complications were absent in 94.4%. In all cases, the OVUF was surgically repaired abdominally with a success rate of 97.5% (346/355). CONCLUSION: The proportion of OVUF is relatively high in the DRC. Most affected patients were young, under-educated, primiparous women living in rural areas. Cesarean section was the sole identified cause of OVUF which was isolated, single, without fibrosis, in majority of cases. Abdominal repair of OVUF was very effective, with good results in almost all cases. Teaching young doctors working mainly in remote areas how to perform safe cesarean section is needed to reduce incidence of OVUF in DRC.

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.

Female genital fistula is a traumatic birth injury which occurs where access to emergency childbirth care is poor. It causes uncontrollable urine leakage and is associated with other physical and psychological symptoms. Due to the urine leakage and its odor, women with fistula are stigmatized which has mental health and economic consequences. Ensuring women's access to fistula surgery and ongoing wellbeing is important for limiting the impact of fistula. After fistula surgery, health risks such as fistula repair breakdown or recurrence or changes to urine leakage can happen, but studies during this time are limited. Our study seeks to measure these health risks and factors influencing these risks quantitatively, and work with patients, community members, and fistula care providers to come up with solutions. We will recruit up to 1000 participants into our study at the time of fistula surgery and follow them for three years. We will collect data on patient sociodemographic characteristics, clinical history, and behavior after fistula repair through patient survey and medical record review. If participants have changes in urine leakage, they will be asked to return to the fistula repair hospital for exam. We will interview about 80 individuals to obtain their ideas for feasible and acceptable intervention options. We expect that this study will help to understand risk factors for poor health following fistula repair and, eventually, improve women's health and quality of life after fistula.

Clinical application of single-layer annular vaginal flap in transvaginal repair for vesicovaginal fistula.

PURPOSE: To compare the first-time success rate and prognosis of repairing vesicovaginal fistula (VVF) by transvaginal and transvesical approaches, and to highlight a modified transvaginal repair technique which only require single layer closure of an annular vaginal flap. METHODS: Retrospective analysis of 57 consecutive patients who underwent VVF repair between 2007 and 2021. Fistula characteristics, operative factors, post-surgical complications and outcomes were analyzed. RESULTS: A total of 57 women with a median age of 50.4 (27-75) years were included. The history ranged from 7 days to 8 years, with an average of 20 months. 56 cases (98.2%) of VVFs were caused by pelvic surgery, and only one resulted from difficult labour. 11 cases (19.3%) had a history of surgical repair failure. All 57 cases of surgery were smoothly completed. Among them, 17 patients underwent transvaginal repair, whereas 40 (70.2%) women had transvesical repair. Transvaginal approach had a significantly shorter operative time, less intraoperative blood loss, reduced postoperative hospital stay, less hospitalization cost and lower minor complication rates than transvesical group (p < 0.05). No serious complications occurred in the two groups. No cystostomy was performed in the transvaginal group, but 12 cases (30%) in the transvesical group. The average follow-up time was 18.5 (3-48) months. The first-time success rates of transvaginal and transvesical techniques were 82.3 and 75%, respectively. CONCLUSION: VVF repair with single layer closure of an annular vaginal flap is a technically feasible, simple and successful approach with significantly better operative parameters and lower complications rates.

The use of tissue adhesive in management of genitourinary fistulas: a systematic review and case report.

INTRODUCTION AND HYPOTHESIS: Articles are getting published on the use of tissue adhesive for vesicovaginal fistula. The objective is to carry out a systematic review on their effectiveness and complications. METHODS: A systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Two reviewers screened abstracts and full-text and extracted data independently. A narrative synthesis was conducted given the heterogeneity of studies. RESULTS: A total of 1032 studies were identified after searching the database, and 14 articles were included in this systematic review. Of the 84 women included, 12 (14.3%) presented failure or recurrence of their fistula tract. The mean time of follow-up was 11.46 months. The average size of the fistula was 1.05 (range 0.1 to 3.9) cm. Most fistulas (81) included were vesicovaginal fistulas. Nine papers reported the usage of fibrin glue in which only three (6.5%) women reported recurrence of the fistula in a delay of 2 weeks to 26 months. The other studies used cyanoacrylate (14 women) and autologous fibrin injection from the patients' blood (31 women). No significant complications were reported. Complications reported were urinary tract infections in 3 women (3.6%), hematuria in 2 women (2.4%), overactive bladder symptoms in 6 women (7.2%) and septic pelvic thrombosis in one woman (1.2%). CONCLUSIONS: Tissue adhesive appears to be a promising alternative for management of urogenital fistulas without reported important complications.

Clinical efficacy of flap transfer coverage in the treatment of vesicovaginal fistula.

INTRODUCTION AND HYPOTHESIS: Vesicovaginal fistula (VVF) brings severe psychological, physiological, and social stress to patients, which seriously affects the quality of their sexual life. Traditional transvaginal repair surgery can cause vaginal shortening. Transferring the lateral free flap can maintain vaginal length. This study was carried out to investigate the clinical efficacy of the surgery of flap transfer coverage for treating VVF. METHODS: A retrospective analysis was performed on 37 patients diagnosed with VVF and repaired by flap transfer coverage in the Urogynecology department of the First Affiliated Hospital of Kunming Medical University from January 2018 to June 2021. All patients took a prone split leg position to repair VVF with the flap transfer covering method and a chart review was performed. RESULTS: Among the 37 patients, there were 34 cases of primary complete healing, and the success rate reached 91.89% without recurrence and complications. Three cases recurred with leakage of urine; cystoscopy showed that the fistula was significantly reduced, and all patients were cured after secondary repair by the same surgical method without complications. CONCLUSIONS: Flap transfer coverage is a safe and effective surgical method for repairing VVF. The prone split leg position can better increase exposure. The fistula being away from the incision suture is the key to the success of the operation. Transferring the fistula can effectively improve the cure rate of VVF. Transferring the lateral free flap can maintain vaginal length.

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 (ß) = 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.

Etiology and factors associated with urogenital fistula among women who have undergone cesarean section: a cross-sectional study.

BACKGROUND: The prevalence and impact of fistulas are more common in developing countries with limited access to emergency obstetric care. As a result, women in these settings often experience adverse psychosocial factors. The purpose of this study was to describe the characteristics of Congolese women who developed urogenital fistula following Cesarean sections (CS) to determine the characteristics associated with two etiologies: (1) prolonged obstructed labor; and (2) a complication of CS following obstructed labor. METHODS: We performed a cross-sectional study on abstracted data from all patients with urogenital fistula following CS who received care during a surgical campaign in a remote area of the Democratic Republic of the Congo (DRC). Descriptive analyses characterized patients with fistula related to obstructed labor versus CS. Univariate and multivariate logistic regression models identified factors associated with obstetric fistula after cesarean delivery following obstructed labor. Variables were included in the logistic regression models based upon biological plausibility. RESULTS: Among 125 patients, urogenital fistula etiology was attributed to obstructed labor in 77 (62%) and complications following CS in 48 (38%). Women with a fistula, attributed to obstructed labor, developed the fistula at a younger age (p = .04) and had a lower parity (p = .02). Attempted delivery before arriving at the hospital was associated with an increased risk of obstetric fistula after cesarean delivery following obstructed labor (p < .01). CONCLUSION: CS are commonly performed on women who arrive at the hospital following prolonged obstructed labor and fetal demise, and account for almost 40% of urogenital fistula. Obstetric providers should assess maternal status upon arrival to prevent unnecessary CS and identify women at risk of developing a fistula.

Transvaginal vesicovaginal fistula closure: A retrospective study of 28 cases at a single facility in Japan.

OBJECTIVES: We aimed to report the background of patients with vesicovaginal fistulas (VVFs) at our center, which has treated a relatively large number of such patients in Japan, as well as the ingenuity and outcomes of vesicovaginal fistula closure (VVFC). We also investigated the causes of VVFs. METHODS: A retrospective review was performed for 28 patients with VVFs treated at our center. Age, body mass index, etiology, site of fistula, and postoperative outcomes were investigated. RESULTS: Twenty-one (75%) fistulas occurred following hysterectomy. The overall success rate of VVFC was 85.7%, and the success rate limited to the first attempt was 89.5%. In 68% of cases, no bladder injury suspected as the cause of VVF was noticed during the surgery. Energy devices were used in all 12 patients for whom information on the type of device used for hysterectomy was confirmed. CONCLUSIONS: To our knowledge, this is the first report to evaluate a relatively large number of VVFCs in Japan. Although VVF is thought to be caused by bladder injury during hysterectomy, delayed thermal damage might also result in this pathology, even if there is no apparent intraoperative bladder injury.

Vesicovaginal Fistulas: Prevalence, Impact, and Management Challenges.

Background and Objectives: Vesicovaginal fistulas (VVFs) are an abnormal communication between the vagina and bladder and the most common type of acquired genital fistulas. This review will address the prevalence, impact, and management challenges of VVFs. Materials and Methods: Epidemiologic studies examining VVFs are considered. In addition, publications addressing the treatment of VVFs are reviewed. Results: VVFs in developing countries are often caused by obstructed labor, while most VVFs in developed countries have iatrogenic causes, such as hysterectomy, radiation therapy, and infection. The reported prevalence of VVFs is approximately 1 in 1000 post-hysterectomy patients and 1 in 1000 deliveries. VVFs affect every aspect of quality of life, including physical, mental, social, and sexual aspects. Prevention of VVFs is essential. Early diagnosis is necessary to reduce morbidity. Nutrition, infection control, and malignancy detection are important considerations during evaluation and treatment. Conservative and surgical treatment options are available; however, these approaches should be customized to the individual patient. The success rate of combined conservative and surgical treatments exceeds 90%. Conclusions: VVFs are considered debilitating and devastating. However, they are preventable and treatable; key factors include the avoidance of prolonged labor, careful performance of gynecologic surgery, and early detection.

[Epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas in Senegal]. / Profil épidémiologique, étiologique et évolutif des fistules vésico-vaginales au Sénégal.

AIM: To evaluate the epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas (VVF) in university hospitals in Senegal. PATIENTS AND METHOD: This is a retrospective, descriptive, single-center study, collecting the records of patients followed for VVF between January 2014 and December 2019 at the Urology and Andrology Department of the Centre hospitalier universitaire Aristide Le Dantec, Dakar, Senegal. The following parameters were studied: age, geographical origin, parity, and etiology of VVF. To assess the evolution of the epidemiological and etiological profile of VVF, we compared our results with those of series published by our structure. RESULTS: Forty-five (45) VVFs were identified over a period of 6 years. This represents an annual average of 7.5 fistulas. The average age was 40±15.13 years with extremes of 13 years and 75 years; 17 patients (37.8%) were older than 45 years. The average parity was 3 with extremes from 0 to 12 children. Multiparous women represented 68.8% of the patients. Obstetric VVF (OVF) was more frequent (48.9%) followed by iatrogenic VVF (33.3%). The mean age was higher in the IVF group compared to the VVF group (32 years) (P = 0.0004). Thirty patients were from the Dakar region and its suburbs (66.6%). The etiology of VVF did not vary according to the geographical origin of the patients (P=NS). VVF was frequently associated with the management of cervical cancer in 42.2% of cases. Comparison of our current data with previous series shows a reduction in the annual incidence of VVF. VVFs, although they have decreased significantly, are still predominant. There is a constant increase in the number of IVF. CONCLUSION: There is an evolution of the epidemiological and etiological profile marked by a decrease in the frequency of VVFs and an increase in that of IVFs. It is also worth noting the frequent association between cervical cancer and VVF. LEVEL OF EVIDENCE: Level 4: retrospective study.

Factors associated with surgical repair success of female genital fistula in the Democratic Republic of Congo: Experiences of the Fistula Care Plus Project, 2017-2019.

OBJECTIVE: We sought to document outcomes and factors associated with surgical success in hospitals supported by the Fistula Care Plus Project in the Democratic Republic of Congo (DRC), 2017-2019. METHODS: This was a retrospective cohort study analysing routine repair data on women with Female Genital Fistula. Univariate and multivariate analyses were conducted to determine factors associated with successful fistula repair. RESULTS: A total of 895 women were included in this study, with a mean age of 34 years (±13 years). The majority were married or in union (57.4%) and living in rural areas (82.0%), while nearly half were farmers (45.9%). The average duration living with fistula was 8 years (±7). Vesicovaginal (70.5%) and complex (59.8%) fistulas were the most common fistula types. Caesarean section (34.7%), obstructed labour (27.0%) and prolonged labour (23.0%) were the main aetiologies, with the causal deliveries resulting in stillbirth in 88% of cases. The vaginal route (74.9%) was the primary route for surgical repair. The median duration of bladder catheterization after surgery was 14 days (interquartile range [IQR] 7-21). Multivariate analysis revealed that Waaldijk type I fistula (adjusted odds ratio [aOR]:2.71, 95% confidence interval [CI]:1.36-5.40), no previous surgery (aOR:2.63, 95% CI:1.43-3.19), repair at Panzi Hospital (aOR: 2.71, 95% CI:1.36-5.40), and bladder catheterization for less than 10 days (aOR:13.94, 95% CI: 4.91-39.55) or 11-14 days (aOR: 6.07, 95% CI: 2.21-15.31) were associated with better repair outcomes. CONCLUSION: The Fistula Care Plus Project in the DRC recorded good fistula repair outcomes. However, further efforts are needed to promote adequate management of fistula cases.

Female urinary incontinence in sub-Saharan Africa.

Urinary incontinence (UI) is highly prevalent amongst women around the world. In this review article we explore UI, its consequences and treatment in sub-Saharan Africa, providing specific examples from Uganda and Malawi. In sub-Saharan Africa the prevalence of UI is difficult to assess because of the wide variation in reporting resulting from patients hiding their condition due to the associated stigma in many communities. Whilst much of the literature from low- or low-middle-income countries focuses on UI from pelvic floor fistula, recent evidence demonstrates that non-fistulous stress, urgency and mixed UI are highly prevalent in sub-Saharan Africa. Incontinence secondary to vesico-vaginal fistula can be related to obstetric causes, mainly obstructed labour. The risk factors for non-fistulous incontinence are similar to those identified in high-income countries, including high parity, vaginal and assisted delivery, gestational age, constipation, obesity, chronic cough and ageing. Urinary incontinence has significant social and emotional consequences, with a high proportion of women in African countries reporting relationship problems, depression and suicidal ideation. There is poor understanding of the perceived aetiology of incontinence in sub-Saharan Africa, which may, in part, act as a barrier for women to seek medical advice. Innovative solutions have been found to manage the large number of obstetric fistulas that are prevalent across Africa, but a lack of capacity in specialists trained to treat women with UI means that more doctors, medical officers and better resource prioritization will be required to help the, as yet unquantified, number of women with non-fistulous leakage. Better patient peri-natal education may reduce the incidence of fistula still further, especially if the stigma felt by women with incontinence is overcome and they are encouraged to seek treatment.

Robotic-assisted vesicovaginal fistula repair using a vaginal cuff flap.

INTRODUCTION AND HYPOTHESIS: Vesicovaginal fistula (VVF) is an abnormal communication between the bladder and the vagina. Complex fistulae include those after failed repair attempts, radiotherapy, measuring ≥ 2 cm, located in the trigone, or with concomitant ureteric strictures or fistulae. We aimed to describe a technique for the robotic repair of a complex VVF using a vaginal cuff flap. METHODS: A 56-year-old woman with a history of ovarian debulking surgery and radiotherapy underwent repair for VVF and rectovaginal fistula. In lithotomy, cystoscopy was performed for fistulous tract cannulation. Port placement, extensive adhesiolysis, and robot docking followed. The vaginal apex was dissected, the VVF excised, and the bladder closed. The rectum was separated from the posterior vaginal wall, the rectovaginal fistula excised, and the rectum closed. A vaginal cuff flap was harvested and interposed between the bladder and the vagina. RESULTS: Operative time was 9 h, estimated blood loss was 300 cc, and no intraoperative complications occurred. The patient was discharged on postoperative day 8. Further management included 37 sessions in a hyperbaric chamber and a transvesical endoluminal bladder closure 10 months after the initial surgery. Follow-up at 30 months shows no fistula recurrence. CONCLUSIONS: Vaginal cuff flaps represent a feasible interposition tissue in patients with hysterectomy for managing complex VVF in the case of omentum unavailability.

Validation of an ovine vesicovaginal fistula model.

INTRODUCTION AND HYPOTHESIS: A representative, large animal model of vesicovaginal fistulas is needed for the training of surgeons and for the development of new surgical techniques and materials for obstetric fistula repair. METHODS: The safety, feasibility, and reproducibility of vesicovaginal fistula creation were studied in 4 adult female sheep. A 1-cm fistula was created between the vagina and the bladder through a transvaginal approach. The defect was allowed to heal for 8 weeks and the animals were then euthanized. The primary outcome was the fistula patency. Secondary outcomes were fistula size, urogenital dimensions, urodynamic evaluation, histology (inflammation, vascularization, collagen deposition) and biomechanical characteristics of the fistula edge (stress at break, maximum elongation, and stiffness). RESULTS: The transvaginal creation of a vesicovaginal fistula was safe. All animals survived the surgical procedure and follow-up period, without complications. Three of the four animals demonstrated a patent vesicovaginal fistula after 8 weeks. Baseline data are provided of the urogenital dimensions and the urodynamic, histological, and biomechanical characteristics of the model. CONCLUSIONS: The ewe is a safe, feasible, and reproducible model for vesicovaginal fistulas. The model can help to study new techniques and materials to boost surgical innovation for vesicovaginal fistula repair.

Concomitant vesicovaginal fistula and rectovaginal fistula in a patient with a neglected pessary placed for pelvic organ prolapse.

INTRODUCTION: Pelvic organ prolapse is a very frequent affection especially in elderly women. Vaginal pessary is a common conservative treatment and recommended as first line therapy. Guidelines recommend to do a regular follow up every 6 to 12 months with a healthcare professional. We report the case of a patient with neglected vaginal pessary who had a vesicovaginal and a concomitant rectovaginal fistula. CASE REPORT: A 84-year-old woman was admitted for chronic pelvic pain and vaginal discharge. An entrapped cube pessary was removed and the diagnostic of a 3cm rectovaginal fistula with a vesicovaginal fistula was made. The patient had a two-stage surgery, vaginal way then open abdominal way, for closing the fistulas. CONCLUSION: Although vaginal pessary is a good conservative treatment for POP, it shall not be neglected or serious complications can be caused.

Cumulative inflammatory burden causing multiple complications after a successful pelvic surgery for advanced ovarian cancer.

Vesicovaginal and rectovaginal fistulas may develop after pelvic metastasis of ovarian carcinoma. Purulent discharge from the vagina results in frequent vaginal or urinary tract infections, and triggers chronic inflammation. These incapacitating symptoms create serious medical and psychosocial problems, and result in low self-esteem and QoL. In this study, we present a metastatic ovarian cancer case admitted with bilateral nephrostomies, nonfunctioning colostomy, and high-volume recto- and vesicovaginal fistulas after debulking. She had frequent urinary tract infections and systemic inflammatory response syndrome. Surgery was performed successfully. However, we had to deal with complications, such as electrolyte imbalance, wound infection and continuing SIRS. Cumulative inflammatory burden caused by advanced carcinoma itself and its complications creates serious medical and psychosocial problems and should be managed with patience.

Transvesical versus extravesical approach to laparoscopic posthysterectomy vesicovaginal fistula repair: A retrospective study from two medical centers.

BACKGROUND: The controversy on the best surgical approach for vesicovaginal fistula (VVF) repair remains due to the scarcity of high-level evidences. We aim to analyze the efficacy and safety of the laparoscopic transvesical (LT) and laparoscopic extravesical (LE) approaches to posthysterectomy VVF (PH-VVF). METHODS: Data of 64 patients with PH-VVFs who were laparoscopicly treated in the First Affiliated Hospital of Nanchang University and the Hangzhou Third Hospital from January 2011 to November 2019 were retrospectively collected. The operative time (OT), estimated bleeding volume (EBV), postoperative bladder function and complications, hospital stay length (HSL), surgery success rate, and recurrence were compared between the two groups. RESULTS: In all, there were no significant differences in baseline characteristics between those two arms. Both approaches were successfully performed without open conversion in either group. The LT group was significantly corrected with a shorter mean OT than the LE group (p < 0.001), regardless of the fistula's position. No significant differences existed in the mean EBV and HSL between the two interventions (p = 0.136 and p = 0.210, respectively). The tendency of postoperative complications and success rates of surgery were also comparable in both groups. The patients in the LT group had similar bladder functions to those in LE group. The recurrence occurred in one patient in each arm during the follow-up periods of 12-36 months. CONCLUSIONS: The LT approach is significantly related to a shorter OT than the LE approach without compromising the safety and success rates in repairing PH-VVF.
