Abstract
OBJECTIVE To present the contemporary evidence on transvaginal urogenital fistulae (UGF) repair with Martius fat pad (MFP), compared to direct graftless fistula repair. METHODS We reviewed all available studies reporting lower UGF repair via the transvaginal approach in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). The primary outcome of interest was the fistula closure rates. When available, patients' baseline characteristics, indications for surgery, and early and late postoperative complications with focus on MFP-related complications are reported. RESULTS AND DISCUSSION In obstetric fistulae, tissue interposition has been almost completely abandoned, with contemporary large series reporting closure rates of >90% with graftless repair, even for complex fistulae. Similarly, most simple, non-irradiated iatrogenic fistulae can be closed safely without or with tissue interposition with success rates ranging between 86% and 100%. However, MFP is valuable in fistulae with difficulty achieving tension-free and layered closure, with significant tissue loss, urethral involvement and with poorly vascularised tissues after radiotherapy, with reported success rates between 80% and 97% in those challenging situations. CONCLUSION A UGF repair should be individualised after considering the specific characteristics and complexity of the procedure. MFP interposition is probably unnecessary for the majority of low (obstetric) fistulae within otherwise healthy tissues. However, MFP may still have a place to maximise outcomes in low-income settings, in select cases with higher (iatrogenic) fistulae, and in most cases with radiotherapy.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVES This study aimed to compare the rates of major and minor complications for vesicovaginal fistula (VVF) repair based on surgeon specialty and to identify risk factors for adverse outcomes. METHODS This was a retrospective cohort analysis of the American College of Surgeons National Surgical Quality Improvement Program between the years 2014 and 2019. Cases were identified using Current Procedural Terminology codes for VVF repair. Minor and major complication rates for VVF repair were compared between 2 cohorts defined by surgeon specialty: gynecology versus urology. Additional outcomes included readmissions and reoperations. Multivariable logistic regression analysis was performed to investigate risk factors for complications. RESULTS A total of 319 VVF repairs were included in the analysis, of which 115 (36.1%) were performed by gynecologists and 204 (63.9%) by urologists. There were no significant differences in the demographic or medical characteristics between the gynecology and urology cohorts except for race. Gynecologists performed more concomitant hysterectomies (10.4% vs 1.0%, P < 0.001) and apical suspension procedures (6.1% vs 0%, P < 0.001). There were no differences in minor (7.8% vs 6.4%, P = 0.623) or major (2.6% vs 3.4%, P = 1.000) complications between the cohorts. The overall readmission rate was 4.7%, and the reoperation rate was 2.2% with no differences between specialties. On multivariable logistic regression analysis, body mass index and concurrent hysterectomy were risk factors for major or minor complications with no increased risk associated with surgeon specialty or route of surgery. CONCLUSIONS Complication rates did not differ for VVF repairs performed by gynecologists compared with urologists. Readmission and reoperation rates were low for both groups.

Abstract
Aim: Vesicovaginal fistula (VVF) is the most common urogenital acquired fistula, and has remained a scourge and of public health importance. VVF can be repaired by transvaginal approach, transabdominal approach or transvesical approach, but the optimal management is still debated. Methods: To demonstrate a suprapubic transvesical approach to repair VVFs using a homemade laparoscopic single-port device. A retrospective review of the medical records of 42 consecutive patients who underwent fistula repair for VVF at our center from January 2012 to March 2018 was performed. VVFs were repaired by a suprapubic transvesical approach using a homemade laparoscopic single-port device. Clinical data, perioperative data and outcomes were collected. The primary outcome was VVF successful closure rate, and secondary outcome was perioperative complications. Results: The mean age of the patients was 44.6 (27–58) yr. The mean follow-up time was 65.6 (32–118) mo. The VVFs were successfully closed in 37 (88.1%) patients after the first surgery, and failure was observed in five patients. Initial failures of all the five patients were cured after a second repair. No major complication occurred as defined by Clavien-Dindo class 2 or greater. Conclusions: Suprapubic transvesical approach to repair VVFs using a homemade laparoscopic single-port device is a simple, effective, and feasible approach offering ideal results without major complications.

Abstract
OBJECTIVE To analyze the prognostic factors affecting the failure of transvaginal repair of vesicovaginal fistula (VVF). METHODS A retrospective nested case-control study was conducted. A total of 15 patients who underwent unsuccessful transvaginal vesicovaginal fistula repair in the Department of Urology, Peking University First Hospital from January 2014 to December 2020 were enrolled as the case group. A total of 60 patients receiving transvaginal vesicovaginal fistula repair by the same surgeon within the same time range, were selected as the control group. The age, body mass index (BMI), etiology of vesicovaginal fistula, associated genitourinary malformation, frequency of repair, characteristics of fistula, surgical procedure, postoperative recovery and other factors were compared between the case group and the control group, and the influencing factors of failure were analyzed. RESULTS The BMI of the case group was (26.3±3.9) kg/m2, the diameter of vaginal fistula was (1.5±0.8) cm, and the operative time of transvaginal repair was (111.8±19.8) min. The proportion of the patients with genitourinary malformations was 4/15, the proportion of the patients with multiple vaginal repairs was 13/15, the proportion of the patients with concurrent ureteral reimplantation was 6/15, and the proportion of the patients with postoperative fever was 5/15. In the control group, the BMI was (23.9±3.0) kg/m2, the diameter of vaginal fistula was (0.8±0.5) cm, the operative time of transvaginal repair was (99.9±19.7) min, the rate of associated genitourinary malformation was 2/60, the rate of multiple transvaginal repair was 18/60, the rate of concurrent ureteral reimplantation was 5/60, and no postoperative fever was found. Compared with the control group, the case group had higher BMI (P=0.013), bigger vaginal fistula (P=0.002), longer time of operation (P=0.027), higher proportion of genitourinary malformations (P=0.013), higher proportion of repeated transvaginal repair (P < 0.001), higher proportion of ureter reimplantation (P=0.006), and higher proportion of postoperative fever (P < 0.001). Multivariate analysis showed that fistula diameter ≥1 cm (OR=10.45, 95%CI=1.90-57.56, P=0.007) and repeated transvaginal repair (OR=16.97, 95%CI=3.17-90.91, P=0.001) were independent prognostic factors for VVF failure in transvaginal repair. CONCLUSION Fistula diameter ≥1 cm and repeated transvaginal repair are independent prognostic factors of failure in transvaginal repair.

Abstract
INTRODUCTION AND HYPOTHESIS To highlight the success rates of two approaches of transvaginal vs. transabdominal closures for the vesicovaginal fistula (VVF) repair and to investigate the patient, fistula, and surgical factors relevant to surgical characteristics and successful outcomes. METHODS Retrospective analysis of 66 consecutive patients who underwent VVF repair between 2005 and 2020. Fistula profile, operative data, and postoperative outcomes were analyzed. Primary outcome was success rate with regard to surgical approach. Secondary outcomes were to compare patients' and surgical characteristics with regard to surgical approach and correlate these characteristics relevant to surgical outcomes. RESULTS A total of 66 women with a median age of 47 (27-82) years were included. Most (93.9%) of the VVFs were secondary to gynecological procedures. Thirteen (19.7%) patients had previous VVF repair. The median time from onset of leakage to surgical repair was 120 days. Forty-nine patients underwent transvaginal repair, whereas 17 (25.7%) women had abdominal repair. The success rates of transvaginal and abdominal techniques were 98% and 82%, respectively. Transvaginal approach had a significantly shorter operative time, less intraoperative blood loss, reduced hospital stay, and lower complication rates (p < 0.005). Age and time to surgery were positively and significantly correlated with surgical time [r (p value): 0.392 (0.003), (0.0386 (0.01)] and estimated blood loss [0.388 (0.002 and 0.410 (0.001)], respectively. CONCLUSION Transvaginal repair of VVF is a technically feasible and successful approach with significantly better operative parameters and lower complications. Despite varied etiology and different surgical approach, age and time to surgery are the main factors that correlate with operative time and blood loss.
