Abstract
BACKGROUND: To describe our initial experience with robotic ureteral reimplantation for the management of ureterovaginal fistulas. METHODS: Between January 2018 and January 2020, four patients received robotic ureteral reimplantation for ureterovaginal fistulas. All patients were diagnosed based on anterograde urography and computed tomography urography (CTU). Follow-up was performed with magnetic resonance urography and renal ultrasound as well as the clinical assessment of symptoms. RESULTS: The mean age of all patients was 50.3 (range, 37-65) years. The cause of the ureterovaginal fistula in four patients was due to a previous hysterectomy. The mean time from fistula diagnosis to robotic repair surgery was 14.5 (range, 3-36) months. All robotic procedures were successfully performed without intraoperative complications or open conversion. The mean operative time was 137 (range, 116-171) minutes, and the mean estimated blood loss was 25 (range, 10-50) mL. No postoperative complications that were high grade (grade III and IV) occurred within one month of surgery. Patients had the double-J (D-J) stents removed 2 months after surgery and the nephrostomy tubes removed 3 months after the operation. There was a 100% success rate without serious complications, such as the leakage of urine and side progressive hydronephrosis, during the 6 to 24 months of follow-up. CONCLUSIONS: Our initial results and experience showed that robotic ureteral reimplantation for the management of ureterovaginal fistula is safe and feasible.
