Virtual Education in Urogynecology: Enhancing Understanding and Management of Pelvic Fistulas.

Introduction: Pelvic fistulas affect a significant number of patients globally, with a relatively low prevalence in the United States. Virtual education offers an effective, scalable solution to bridge this educational gap and lead to a deeper understanding of more common conditions, such as urinary and fecal incontinence. Methods: We developed two virtual cases on rectovaginal and vesicovaginal/ureterovaginal fistulas to enhance medical students' exposure, knowledge, and confidence regarding assessment of pelvic fistulas. The cases could be completed in approximately 30 minutes, asynchronously, and at students' own pace. The cases were integrated into an OB/GYN clerkship. We conducted a survey among students receiving the cases to gather feedback on usability, acceptability, and educational value, which guided subsequent improvements. Results: Forty medical students, ranging from first to third year, participated in the urogynecology elective; 21 (53%) completed the survey. Ninety-one percent agreed or strongly agreed they were satisfied with the cases. All respondents found the format easy to use and appropriate for their level of learning. Most reported the cases improved their confidence in nonsurgical and surgical management options for pelvic fistulas. Discussion: Offering virtual and interactive patient cases on e-learning platforms represents an innovative approach to increasing clinical exposure to urogynecologic disorders. By providing medical students with the opportunity to interact with pelvic fistulas virtually, these cases can help bridge a gap in clinical education. Future exploration is valuable for examining knowledge deficiencies and developing cost-effective, self-paced, easily accessible educational resources to advance medical training and optimize patient care.

Correlates of fertility desires in women with urogenital fistula in the Democratic Republic of Congo: a cross-sectional study of 1,646 women.

BACKGROUND: Studies on fertility desires among fistula patients in the Democratic Republic of Congo (DRC) have been conducted on fewer patients. Furthermore, these studies have adopted a univariate descriptive approach. This study aims to examine the determinants of fertility desires among patients with fistula in the DRC. METHODS: This cross-sectional study included women aged 15-49 whose fistulas were repaired by the Panzi Hospital mobile team in seven DRC regions between 2013 and 2018. Univariate and bivariate descriptive analyses were performed using the frequency distribution table and the chi-square test. Adjusted odds ratios with their 95 confidence intervals from logistic regression were used to analyze factors associated with fertility desire after fistula repair. All analyses were stratified by parity level for all women aged 15-49 and 20-34 years. RESULTS: Of the 1,646 women aged 15-49 and 808 aged 20-34, 948 (57.6%) and 597 (73.8%), respectively, wanted to have children after fistula repair. Among women aged 15-49 and 20-34 years, the desire to have children was parity-specific. It was negatively associated with age at all parity levels. In women with low parity, the desire for children was significantly negatively associated with a high number of surgeries, abortions, and fistula duration. It tended to decrease with time, but was particularly high in 2014 and 2017. It was high among the Protestant women. Among medium-parity women, it was significantly lower in urban areas and among widows, but higher among women who had more than two abortions. Among high-parity women, it was negatively associated with education level. CONCLUSION: To help women with fistula achieve or approach their desired number of children, our findings suggest that (1) counseling is needed for women with a high desire for children; (2) the human, material, and financial resources needed to eliminate fistula in the DRC should be made available; and (3) medical and nursing staff should be sufficiently and effectively trained to minimize the number of unsuccessful surgeries performed on women with fistula.

Surgeon's point of view in vesico-vaginal fistula management.

OBJECTIVES: Vesicovaginal fistulas (VVF) are the most commonly acquired fistulas of the urinary tract. The management of VVF is mainly based on expert opinion and surgeon experience. This study aims to provide the practice patterns and outcomes of vesicovaginal fistula (VVF) management in Indonesia. METHODS: This study utilizes the results of a survey among the surgeons who performs VVF repair in referral hospitals throughout Indonesia between June and July of 2021. Data analysis was carried out with SPSS descriptively by displaying the relative frequency of the answers to each question of the questionnaire form. RESULTS: We collected responses from 93 respondents consisting of 68 urologists and 25 gynecologists. The most commonly reported cause of VVF was obstetric (50.5%). Most respondents confirmed the diagnosis of VVF by cystoscopy (81.7%). Waiting time to repair VVF was generally 12 weeks (79.6%), while the transvaginal approach repair was more often performed (77.4%). An additional procedure, such as tissue interposition was performed in 50.5% of cases. Tissue interposition was mostly indicated in recurrent VVF (81%), with omentum being the most selected tissue interposition (71%). When indicated, the most selected method of transabdominal approach was open transvesical (54,84%). A laparoscopic approach was performed only in 7.5% of cases. Overall, the success rate for VVF repair in Indonesia was 70-100% at first attempt. CONCLUSIONS: The transvaginal approach is preferred, either with or without an interposition tissue flap. The success rate at the first attempt is satisfactory.

Retained Tampon Fragment as an Unusual Cause of Vesicovaginal Fistula.

BACKGROUND: Vesicovaginal fistula (VVF) is an uncommon cause of urinary incontinence (UI). Iatrogenic etiologies, especially abdominal hysterectomy, are most common; however, a minority of VVFs are caused by retained foreign bodies. Objects associated with VVF include intrauterine devices, gauze, pessaries, bottle caps, and sexual aids, but retained tampons or other menstrual products have not been commonly reported. CASE: We present the case of a 53-year-old woman, gravida 0, with no prior pelvic surgery, with 2 months of intermittent UI and hematuria. Although initial diagnostic test results were negative, cystoscopy and vaginoscopy eventually confirmed the diagnosis of VVF associated with a retained foreign body. In the operating room, all debris was removed using vaginoscopy, and the VVF was repaired using a modified Latzko technique. At the patient's 9-week follow-up appointment, she was found to have complete healing of the VVF and resolution of associated symptoms. CONCLUSION: This is a case of VVF secondary to a retained tampon fragment. In addition to this uncommon etiology, our patient's presenting symptoms were atypical, leading to a delay in diagnosis and treatment for which vaginoscopy was critical.

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.

Single-Port Transvesical Vesico-Vaginal Fistula Repair: An Initial Experience.

INTRODUCTION: Vesicovaginal fistula (VVF) is the most common urogenital fistula due to iatrogenic cause, primarily associated with gynecologic surgery (1). Although both conservative and surgical management may be considered, the optimal treatment is still uncertain and several studies were published using different techniques (open, laparoscopic or robotic) and approaches (extravesical, transvesical or transvaginal) (2-5). In this context, we aim to report our initial experience repairing VVF with Single-Port (SP) Transvesical (TV) access. MATERIALS AND METHODS: Four patients with a diagnosis of VVF underwent SP-TV VVF repair between May 2022 and December 2023. Diagnosis was confirmed by cystoscopy, cystogram and in two cases by CT Urogram. Under general anesthesia, before robotic time, patients were placed in lithotomy position and a preliminary cystoscopy was performed. Fistula was noted and a 5fr stent was placed through the fistulous tract. Two ureteral stents were placed. Then, with patient supine, a transverse suprapubic 3cm incision and 2cm cystotomy were made for SP access. First step was to mark and remove fistula tract to the vagina. The edges of the vagina and bladder were dissected in order to have a closure free of tension and to create three different layers to close: vagina, muscularis layer of the bladder and mucosal layer of the bladder. A bladder catheter was placed, and the two ureteral stents were removed at the end of procedure. RESULTS: Mean age was 53 years old and three out of 4 patients developed VVF after gynecologic surgery. Two patients underwent VVF repair 6 and 8 months after total hysterectomy. One patient developed VVF after total hysterectomy and oophorectomy followed by radiation therapy. Last patient developed VVF after previous urological procedure. Fistula diameter was between 11 and 15mm. Operative time was 211 min, including preliminary cystoscopy, stents placement and SP-access. All patients were discharged on the same day with a bladder catheter, successfully removed between post-operative day 14-18 after negative cystogram. Only in one case a ureteral stent was left because the fistula was closed to the ureteral orifice and we reported one case of UTI twelve days after surgery, treated with outpatient antibiotics. Mean follow-up was 8 months, patients were scheduled for regular follow-up visits and no recurrence was reported. All patients have at least 3 months of post-operative follow-up. CONCLUSIONS: Our experience suggests that SP Transvesical VVF repair may be considered as a safe and feasible minimally invasive treatment for small/medium fistulae (10-15mm).

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.

Measuring the cost-effectiveness of treating rectovaginal and vesicovaginal fistulas: A multicenter global study by the Fistula Foundation.

OBJECTIVE: Surgery for obstetric fistula is a highly effective treatment to restore continence and improve quality of life. However, a lack of data on the cost-effectiveness of this procedure limits prioritization of this essential treatment. This study measures the effectiveness of fistula surgeries using disability-adjusted life years (DALYs) averted. METHODS: In 2021 and 2022, the Fistula Foundation funded 20 179 fistula surgeries and related procedures at 143 hospitals among 27 countries. We calculated DALYs averted specifically for vesicovaginal fistula and rectovaginal fistula procedure types (n = 13 235 surgeries) by using disability weights from the 2019 Global Burden of Disease study. We based cost calculations on direct treatment expenses, including medical supplies, health provider fees, and preoperative and postoperative care. We measured effectiveness using data on the risk of permanent disability, country-specific average life spans, and treatment outcomes. RESULTS: The total treatment cost was $7.6 million, and a total of 131 433 DALYs were averted. Thus, the cost per DALY averted-the cost to restore 1 year of healthy life-was $58. For this analysis, we took a cautious approach and weighted only surgeries that resulted in a closed fistula with restored continence. We calculated DALYs averted by country. Limitations of the study include data entry errors inherent in patient logs and lack of long-term outcomes. CONCLUSION: The current study demonstrates that obstetric fistula surgery, along with having a significant positive impact on maternal health outcomes, is highly cost-effective in comparison with other interventions. The study therefore highlights the benefits of prioritizing fistula treatment as part of the global agenda for maternal health care.

Determinants and predictive model of failure of surgical repair of obstetric vesico-vaginal fistula in the Democratic Republic of the Congo.

INTRODUCTION: Surgical repair of obstetric fistula aims to restore the anatomical and functional integrity of the urinary tract, enabling affected women to regain their dignity and quality of life. However, such repairs can end in a failure. The aim of this study is to develop a predictive score to identify factors influencing failure of surgical repair of obstetric vesico-vaginal fistula (FSROVVF) in the Democratic Republic of the Congo. METHODS: This was an analytical cross-sectional study of 318 women with obstetric vesico-vaginal fistula (OVVF) who had undergone surgical management. A bivariate and then a multivariate analysis were performed. Score discrimination was assessed using the ROC curve and C-index, and score calibration using the Hosmer-Lemeshow test. RESULTS: Surgical repair of OVVF was unsuccessful in 16.98% of cases (54/318). After logistic modeling, six criteria emerged as predictive factors for FSROVVF: the presence of fibrosis (AOR = 5.01; 95% CI:1.73-14.49), the presence of 2 or more fistulas (AOR = 9.04; 95% CI:3.01-27.13), the association of OVVF with another anatomoclinical entity of fistula (AOR = 3.16; 95% CI:1.09-9.13), the fistula size > 3 cm (AOR = 3.65; 95% CI:1.36-9.76), the peri-operative hemorrhage (AOR = 7.01; 95% CI:2.33-21.03), and the post-operative infection (AOR = 178.89; 95% CI:26.09-1226.64). A score ranging from 0 to 13 points was obtained, of which a value ≤ 5 points defines a low risk of FSROVVF, a value between 6 and 8 points defines a moderate risk and value ≥ 9 points corresponds to a high risk of FSROVVF. The area under the ROC curve of the score is 0.925 with a sensitivity of 61.11%, a specificity of 96.59%, a positive predictive value of 78.57% and a negative predictive value of 92.39%. CONCLUSION: This study demonstrated that the number of fistulas ≥ 2, fistula size > 3 cm, fibrosis, association of OVVF with other types of fistulas, peri-operative hemorrhage, and post-operative infection are factors predictive of FSROVVF. These six factors are key contributors to the score used to predict FSROVVF. Once validated, this score will inform and enable preoperative counseling regarding the prognosis and the chances of a successful outcome of surgical repair of OVVF.

A novel magnetic compression technique for establishment of a vesicovaginal fistula model in Beagle dogs.

Vesicovaginal fistula lacks a standard, established animal model, making surgical innovations for this condition challenging. Herein, we aimed to non-surgically establish vesicovaginal fistula using the magnetic compression technique, and the feasibility of this method was explored using eight female Beagle dogs as model animals. In these dogs, cylindrical daughter and parent magnets were implanted into the bladder and vagina, respectively, after anesthesia, and the positions of these magnets were adjusted under X-ray supervision to make them attract each other, thus forming the structure of daughter magnet-bladder wall-vaginal wall-parent magnet. Operation time and collateral damage were recorded. The experimental animals were euthanized 2 weeks postoperatively, and the vesicovaginal fistula gross specimens were obtained. The size of the fistula was measured. Vesicovaginal fistula was observed by naked eye and under a light microscope. Magnet placement was successful in all dogs, and remained in the established position for the reminder of the experiment. The average operation time was 14.38 min ± 1.66 min (range, 12-17 min). The dogs were generally in good condition postoperatively and were voiding normally, with no complications like bleeding and urine retention. The magnets were removed from the vagina after euthanasia. The vesicovaginal fistula was successfully established according to gross observation, and the fistula diameters were 4.50-6.24 mm. Histological observation revealed that the bladder mucosa and vaginal mucosa were in close contact on the internal surface of the fistula. Taken together, magnetic compression technique is a simple and feasible method to establish an animal model of vesicovaginal fistula using Beagle dogs. This model can help clinicians study new surgical techniques and practice innovative approaches for treating vesicovaginal fistula.

Cystitis glandularis with concomitant Crohn's disease leading to a paroxysm of Crohn's disease with ulcerated external iliac vessels.

•we report the case of a 36-year-old female patient who presented to our hospital with a diagnosis of cystitis glandularis manifesting as a vesicovaginal fistula. She underwent cystoscopic biopsy at a local hospital, but anti-inflammatory treatment was ineffective, and the patient was experiencing low urination frequency and urgency, as well as pain. The patient underwent laparoscopic repair of a cystoscopy-confirmed vesicovaginal fistula. After surgery, the patient experienced a paroxysm of Crohn's disease with multiple small bowel fistulas and erosion of the external iliac vessels that ruptured to form an external iliac vessel small bowel fistula. The fistula was confirmed by surgical exploration, and the patient eventually died.

Patient characteristics, surgery outcomes, presumed aetiology and other characteristics of fistula surgeries and related procedures supported by Fistula Foundation from 2019 to 2021: a multicentre, retrospective observational study.

OBJECTIVES: Obstetric fistula is a devastating childbirth injury primarily caused by prolonged, obstructed labour. It leaves women incontinent, severely stigmatised and isolated. Fistula repair surgery can restore a woman's health and well-being. Fistula Foundation, a non-profit organisation, works in partnership with local hospitals and community organisations in Africa and Asia to address key barriers to treatment and to increase the number of women receiving surgical care. This paper presents data on fistula and fistula repair surgery across a large global network of hospitals supported by Fistula Foundation. The data were collected between 2019 and 2021. DESIGN: Multicentre, retrospective, observational, descriptive study. SETTING AND PARTICIPANTS: The study analysed deidentified data from 24 568 surgical repairs supported by Fistula Foundation to treat women with obstetric fistula at 110 hospitals in 27 countries. RESULTS: The data highlight patient characteristics and key trends and outcomes from obstetric fistula repair surgeries and related procedures. Of those surgeries, 87% resulted in a successful outcome (fistula dry and closed) at the time of discharge, highlighting the effectiveness of fistula repair in restoring continence and improving quality of life. Over the period studied, the number of supported surgeries increased by 14%, but there remains an urgent need to strengthen local surgical capacity and improve access to treatment. Women suffered an average of 5.7 years before they received surgery and only 4% of women sought care independently. This underscores the importance of enhancing community awareness and strengthening referral networks. CONCLUSIONS: This research provides essential insight from a vast, global network of hospitals providing highly effective fistula repair surgery. Further investment is needed to strengthen surgical capacity, increase awareness of fistula and remove financial barriers to treatment if stakeholders are to make significant progress towards the United Nations' ambitious vision of ending fistula by 2030.

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.

Genitourinary Fistula: epidemiology, changing trends in etiology and management: A tertiary care institute's perspective.

INTRODUCTION: Urogenital fistula is a physically, socially and psychologically devastating condition for the patient. In developed countries, these fistulae are typically related to gynecological surgery, pelvic pathology like malignancy or post radiation therapy. In contrast, classical teaching is that urogenital fistulae in the developing countries like India are usually associated with prolonged labor and obstetric complications. This retrospective study conducted at a tertiary care health Institute shows a paradigm shift in epidemiology, etiology and management of genitourinary fistulae in India in recent times. METHODS: This retrospective study included patients undergoing surgical repair for various genitourinary fistulae at our institute from 2016 to 2022. Epidemiology, etiology, site, size and number of fistulae, clinical presentation, and management records of these patients were recorded and reviewed retrospectively. RESULTS: In our study, the mean age of the patients was 38.4 ± 10.2 years. Vesicovaginal Fistula (VVF) was found to be most common fistula in the study population (87.5%) followed by vesicouterine (7.1%) and urethrovaginal fistula (5.4%). The causes of genitourinary fistula were iatrogenic (73.2%), carcinoma of cervix (16.1%), obstructed prolonged labor (7.1%), and genitourinary tuberculosis (3.57%). Among the 48 vesicovaginal fistulas that underwent surgery, 45.8% were treated using a transvaginal approach, 29.2% were managed through a laparoscopic transabdominal repair, and 25% were addressed using a robotic approach. Recurrence occurred in 7.1% of the operated patients. CONCLUSION: Enhanced healthcare services in the country have contributed to a decrease in the incidence of obstructed labor, subsequently reducing related injuries. Iatrogenic injuries resulting from gynecological surgeries and carcinoma cervix have given rise to more complex fistulas, necessitating the implementation of advanced treatment strategies.

Giant stone adhered in the vaginal cavity in a female patient with type 2 diabetes mellitus: a case report.

BACKGROUND: Bladder lithiasis comprises 5% of urological lithiasis. Large bladder stones associated with vesicovaginal fistulas are rare, and the risk factors are not an isolated process. There are metabolic comorbidities associated with this pathology, including diabetes mellitus. CASE PRESENTATION: A 70-year-old Mestizo patient is presented, reporting dysuria, pollakiuria, and abdominal pain of 4 months of evolution, located in the hypogastric region, also with a sensation of a foreign body in the vaginal introitus. In her pathological history, she presented type 2 diabetes mellitus. A computed tomography scan of the abdomen and pelvis was performed, reporting a tumor lesion in the abdominal wall. Therefore, surgical intervention was performed by cystolithotomy, obtaining a giant stone adhered to the vaginal wall with a size of 10 cm × 12 cm. CONCLUSION: Early detection of this pathology should be exhaustive in patients with characteristics and comorbidities associated with stone development to avoid possible complications, such as vesicovaginal fistulas.

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.

HEAL Africa score to predict failure of surgical repair of obstetric urethro-vaginal fistula in the Democratic Republic of the Congo.

INTRODUCTION: Obstetric fistula (OF) repair surgery aims to restore the anatomical and functional integrity of the urinary tract, allowing affected women to regain their dignity and quality of life. However, in some cases, this surgical repair may fail. The objective of this study was to develop a predictive score to identify factors associated with the failure of surgical repair of obstetric urethro-vaginal fistula (FSROUVF) in the Democratic Republic of the Congo (DRC). METHODS: This is an analytical cross-sectional study of 358 patients with obstetric urethro-vaginal fistula (OUVF) who received surgical repair. We conducted bivariate and multivariate analyses. Score discrimination was assessed using the receiver operating characteristic (ROC) curve, C-index, and score calibration according to the Hosmer-Lemeshow test. RESULTS: Surgical repair of OUVF failed in 24.86% of cases (89/358). After logistic modelling, 6 criteria predicted FSROUVF: the use of intravaginal indigenous products (AOR = 3.59; 95% CI: 1.51-8.53), the presence of fibrosis (AOR = 6.37; 95% CI: 1.70-23.82), the presence of 2 or more fistulas in the same patient (AOR = 7.03; 95% CI: 3.14-15.72), the total urethral damage (AOR = 3.29; 95% CI: 1.36-7.95), the fistula size > 3 cm (AOR = 5.65; 95% CI: 2.12-15.01), and the postoperative infection (AOR = 351.10; 95% CI: 51.15-2409.81). A score of 0 to 14 was obtained, with a value ≤5 points indicating a low risk of FSROUVF, a value between 6 and 8 indicating a moderate risk, and a value ≥9 points corresponding to a high risk of FSROUVF. The area under the ROC curve of the score is 0.938 with a sensitivity of 60.67%, a specificity of 96.28%, a positive predictive value of 84.38%, and a negative predictive value of 88.10%. CONCLUSION: We report a FSROUVF rate in the DRC approaching a quarter of operative patients. Predictors of failure included fibrosis, presence of 2 or more fistulas, total urethral involvement, fistula size greater than 3 cm, postoperative infection, and use of intravaginal indigenous products. These factors are constitutive of the HEAL Africa score, which once validated, may have value in pre-operative counselling of patients. This study could be valuable for policy and strategies to address the problem of OUVF in the DRC and in resource limited settings more generally.

The Necessity of Incorporating an Interposition Flap During Vesicovaginal Fistula Repair: Can Modifying the Method of Vaginal Repair Serve as a Substitute? A Randomized Clinical Trial.

PURPOSE: Traditionally, an omental flap is employed to reduce the risk of recurrence of vesicovaginal fistula (VVF) repair. In this study, we employed a modified surgical technique wherein the vaginal defect was closed using Connell sutures, without incorporation of an omental flap, aiming to mitigate potential complications. MATERIAL AND METHOD: Between 2010 to 2018, the current randomized clinical trial was conducted on 52 women who were candidates for open fistula repair. The patients were randomly allocated into two groups. In one group, the conventional method of fistula repair was performed involving an omental flap, while in the other group, we used a modified approach with a variation in the vaginal wall closure technique. In-hospital variables, including the length of surgery, hospital stay, and occurrences of ileus, were recorded. Patient follow-up extended for one year, with assessments conducted one, six, and twelve months postoperatively. These evaluations encompassed pad test to ascertain success rates and identify any potential complications. RESULTS: The final analysis comprised 49 patients, with an average age of 46.5 years. Baseline characteristics were comparable between the two groups (P-values > 0.05). The modified technique was associated with significantly reduced surgical duration (P = ˂ 0.001), and shorter hospital stays (P < 0.001). Ileus occurrence was reduced, but it was not significant(P = 0.856). However, the success rate showed no significant difference between the groups, with a success rate of 100% for the modified technique compared to 91.6% for the classic O'Conner method (P = 0.288). CONCLUSION: Based on the findings of this study, vaginal wall closure using Connell sutures during VVF repair demonstrates a success rate equivalent to the classic approach involving an omental flap. Moreover, this technique presents a reduced incidence of adverse effects, along with decreased surgical duration, hospital stay, and postoperative ileus.
