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.

OBJECTIVE: Vesicovaginal fistula (VVF) causes detrimental psychosomatic effects on a woman. It is repaired using open abdominal as well as laparoscopic approach. Here we compare a series of open versus laparoscopic VVF repairs done at a single centre. METHODS: Retrospectively data of patients undergoing VVF repair in our department between January 2011 to December 2014 was analyzed. Patients who had a single, primary, simple VVF following a gynaecological surgery were included in the study. 26 patients met all the criteria. Out of these, thirteen patients had undergone a laparoscopic VVF repair (group 1) while thirteen had undergone an open transabdominal VVF repair (group 2). RESULTS: Mean fistula size was 2.14±0.23 cm in group 1 and 2.18±0.30 cm in group 2, which was comparable. Mean blood loss was 58.69±6.48 mL in group 1 and 147.30±19.24 mL in group 2, which is statistically significant (P<0.0001). Mean hospital stay was 4 days in group 1 and 13 days in group 2 which is statistically significant (P<0.0001). The analgesic requirement (diclofenac) was 261.53±29.95 mg in group 1 and 617.30±34.43 mg in group 2, which is statistically significant (P<0.0001). Fistula repair was successful in all the patients in both the groups. CONCLUSION: The present study shows that laparoscopic VVF repair results in reduced patient morbidity and shorter hospital stay without compromising the results. So laparoscopic repair may be a more attractive treatment option for patients with post gynecology surgery VVF.

OBJECTIVE: To explore new methods for laparoscopic repair of vesicovaginal fistula. METHODS: Five patients with vesicovaginal fistula in Xiangya Hospital, Central South University, were reviewed retrospectively from May 2013 to July 2014. All patients underwent laparoscopic repair surgery, and the surgical methods were analyzed. The operative time, intraoperative blood loss, and hospital stay time were recorded. The duration of follow-up was from 4 to 12 months. RESULTS: Th e surgical procedures for all 5 patients were successful. No open surgery was required. The operative time was 70~120 (mean: 97) min, the intraoperative blood loss was 40~70 (mean: 54) mL, the hospital stay time was 4~8 (mean: 5.8) days. During the follow up of 4~12 (mean: 7.6) months, no recurrence was observed. CONCLUSION Laparoscopic repair of vesicovaginal fistula is a feasible and safe and effective procedure with less blood loss and shorter recovery time, which can minimize surgery damage and improve successful rate.

Vesicovaginal fistula (VVF) may be caused by prolonged obstructed labor, gynecologic, urologic, or other pelvic surgery, malignancy, radiation, infection and trauma. Here we report a case of VVF caused by nail penetrating trauma in a young woman with genital bleeding after first intercourse. This is a rare etiology of VVF. We also explain the operative technique used to repair the fistula.

PURPOSE: Urologic injuries occur frequently during surgery in the pelvic cavity. Inadequate diagnosis and treatment may lead to severe complications and side effects. This investigation examined the clinical features of urologic complications following obstetric and gynecologic surgery. MATERIALS AND METHODS: We accumulated 47,318 obstetric and gynecologic surgery cases from 2007 to 2011. Ninety-seven patients with urological complications were enrolled. This study assessed the causative disease and surgical approach, type, and treatment method of the urologic injury. RESULTS: Of these 97 patients, 69 had bladder injury, 23 had ureteral injury, 2 had vesicovaginal fistula, 2 had ureterovaginal fistula, and 1 had renal injury. With respect to injury rate by specific surgery, laparoscopic-assisted radical vaginal hysterectomy was the highest with 3 of 98 cases, followed by radical abdominal hysterectomy with 15 of 539 cases. All 69 cases of bladder injury underwent primary suturing during surgery without complications. Of 14 cases with an early diagnosis of ureteral injury, 7 had a ureteral catheter inserted, 5 underwent ureteroureterostomy, and 2 underwent ureteroneocystostomy. Of nine cases with a delayed diagnosis of ureteral injury, ureteral catheter insertion was carried out in three cases, four cases underwent ureteroureterostomy, and two cases underwent ureteroneocystostomy. CONCLUSIONS: Bladder injury was the most common urological injury during obstetric and gynecologic surgery, followed by ureteral injury. The variety of injured states, difficulty of diagnosis, and time to complete cure were much greater among patients with ureteral injuries. Early diagnosis and urologic intervention is important for better outcomes.

PURPOSE: To report our technique for and experience with robot-assisted laparoscopic radical cystectomy (RARC) with orthotopic neobladder (ON) formation in a cohort of bladder cancer patients. MATERIALS AND METHODS: Between December 2007 and December 2011, a total of 35 patients underwent RARC. The patients' mean age was 63.3 years and their mean body mass index was 23.7 kg/m2. Thirty patients had a clinical stage of T2 or higher. Postoperative mean follow-up duration was 25.5 months. In 5 patients, a 4-cm midline infraumbilical skin incision was made for an ileal conduit (IC) and the stoma formation was similar to the open procedure. In 30 patients undergoing the ON procedure, the skin for specimen removal and extracorporeal enterocystoplasty was incised infraumbilically in the early 5 cases with redocking (ON-I) and suprapubically in the latter 25 cases without redocking (ON-S). RESULTS: The mean operative times of the IC, ON-I, and ON-S groups were 442.5, 646.0, and 531.3 minutes, respectively (p=0.001). Mean console and lymph node dissection time were not significantly different between the groups. Mean urinary diversion times in each group were 68.8, 125.0, and 118.8 minutes, respectively (p=0.001). In the comparison between the ON-I and ON-S group, only operative time was significant. Four patients required a blood transfusion. We had no cases of intraabdominal organ injury or open conversion. Thiry-three patients (94.2%) had a pathologic stage of T2 or higher. Two patients (5.7%) had lymph node-positive disease. Postoperative complications included ileus (n=4), stricture in the uretero-ileal junction (n=2), and vesicovaginal fistula (n=1). CONCLUSIONS: Our robotic neobladder-suprapubic incision without redocking procedure is easier and more rapid than that of infraumbilical incision with redocking.

PURPOSE: In developed countries, vesicovaginal fistula occur from various pelvic operations including total hysterectomy, leading to urinary leakage and incontinence. Although various methods have been proposed for adequate tissue coverage in fistula repair, the surgical treatment of is not simple and still controversial. We report a case of neobladder-vaginal fistula repair using modified Martius fat pad flap. METHODS: A 62-year-old female patient underwent radical cystectomy with total abdominal hysterectomy and neobladder formation due to invasive bladder tumor 5 years ago. For 3 years following the operation, urine leakage was observed. Exploration demonstrated neobladder-vaginal fistula and primary repair including fistulectomy and direct closure was performed. Urinary incontinence relapsed 2 years after primary repair, and after demonstrating the recurrence of fistula on urography, repair of recurrent fistula was performed. After dissection of vagina and neobladder and closure of fistula by urologic surgeon, fibroadipose flap was elevated, rotated and advanced through the tunnel at vaginal sidewall, and interpositioned to the fistula site between neobladder and vagina. RESULTS: There was no acute complication after the surgery and urethral catheter was extracted on the 8th day after the operation. During six month follow-up period after the operation, there is no clinical evidence of fistula recurrence. CONCLUSION: From our clinical experience and literature review, we think Martius fat pad flap is a useful technique in management of neobladder-vaginal fistula, for it provides enough vascularity, major epithelization surface and better lymphatic drainage, and also prevents overlapping of vesical, vaginal suture lines at the same time.

To discuss the diagnosis and therapy of congenital vesicovaginal fistula (VVF). We reported 1 case of pregnancy and congenital VVF and summarized the pathogenesis and characters. Congenital VVF is extremely rare and characterised by continuous urinary leakage,cyclical hematuria with severe suprapubic pain. It is always associated with other urinary tract abnormalities, urinary tract infection and stone. The pathogenesis is related with genetic, environment, drugs, radiation and incomplete fusion of mullerian. The diagnosis relies on clinical manifestation and radiological examinations.Surgical resection is the key to treatment. Pregnancy and congenital VVF is extremely rare and always misdiagnosised associated with other urinary tract abnormalities. Early diagnosis and making sure the location, size and relationship with other tissues are important. Reasonable preoperative preparation, surgical and postoperative surgical care are the key for treatment.

The most common cause of vesicovaginal fistulasis injury to the bladder at the time of surgery. The operation most frequently responsible for vesicovaginal fistula formation is hysterectomy. The first successful transvaginal approach to vesicovaginal fistula repair was reported by Sims in 1838. Although many surgical procedures exist, there is no best approach for all patients with vesicovaginal fistula. However, it is an essential surgical principle that the fistulous tract and scar should be excised completely. Here we report our technique using a transurethral pointed electrode for the treatment of multiple, small vesicovaginal fistulas and its outcome.
