Robotic ureteral reimplantation for the management of ureterovaginal fistula: four cases at a single center.

Abstract

BackgroundTo describe our initial experience with robotic ureteral reimplantation for the management of ureterovaginal fistulas.MethodsBetween 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.ResultsThe 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.ConclusionsOur initial results and experience showed that robotic ureteral reimplantation for the management of ureterovaginal fistula is safe and feasible.
