Robot Assisted Laparoscopic Repair of Vesicovaginal Fistula: A Retrospective Study at a Tertiary Care Centre, Chennai, India

Abstract

Introduction: Vesicovaginal Fistula (VVF) is the most common acquired fistula of the urinary tract in women. Robotic surgery is recently introduced for VVF repair and has benefits over conventional methods. Aim: To describe experience with robot-assisted laparoscopic repair of VVF in patients. Materials and Methods: This was a retrospective observational study conducted from February 2014 to February 2018, at Department of Urology, Apollo Main Hospital, Chennai, Tamil Nadu, India. The study included 24 patients who underwent robot-assisted laparoscopic VVF repair. After cystoscopy ureteric catheter was passed through the fistula and retrieved through vagina. Bilateral ureteric catheters were placed simultaneously with vaginal packing. Da Vinci Si robot was docked with patient in trendelenburg position. After trocar placement transperitoneally the fistula was approached. Through vertical or transverse cystotomy, fistula was identified. With the circumferential incision around the fistula, both the bladder and vagina was separated and the fistulous tract was excised. Bladder was closed vertically and vaginal opening was closed transversely interposing the Omentum. Statistical analyses were performed using the Statistical Package for Social Sciences (SPSS) version 20.0. Results: The mean age of participants was 40.33 years. Elective hysterectomy done for benign conditions (91.67%) was the major cause of VVF in patients followed by emergency hysterectomy (8.33%). All of the patients underwent adhesiolysis while two patients performed right ureteric re-implantation additionally. The median operative time was 127.50 minutes. The median duration of drain and hospital stay was three days each. Urethral Foley’s catheter removal done at 2-3 weeks based on operating surgeon’s preference and the mean duration of follow-up was 26 months. Conclusion: Robot-assisted laparoscopic VVF repair is convenient and an effective approach in the successful management of VVF in complex fistulas and recurrent cases.
