[Transumbilical single-incision laparoscopic ureterolithotomy]

laparoendoscopic single-site surgery (LESS) using transumbilical access and conventional laparoscopic instruments is a very attractive alternative to perform ureterolithotomy for ureteral stone with failed endourological management.

a 29-year-old woman presented with chronic right lumbar pain and a 1.2 cm impacted calculus localized at transition of abdominal to pelvic ureter. Semi-rigid ureteroscopy had failed to fragment the stone and shockwave lithotripsy was not available. Double-J ureteral catheter had been inserted preoperatively. We performed a transumbilical single-incision laparoscopic ureterolithotomy. Three conventional trocars were inserted in a single semi-circular umbilical incision. Right colon was detached and the ureter was identified. Calculus was extracted and the ureteral incision was closed with intracorporal sutures.

ureterolithotomy was successfully completed, with all the operative steps performed transumbically. Operative time was 180 minutes. No single-port device or articulating and bent instruments were utilized. Estimated blood loss was less than 50 mL. No intraoperative, access-related and postoperative complications took place. The duration of hospitalization was 24 hours and scarless appearance was observed on postoperative day 15.

transumbilical single-incision laparoscopic ureterolithotomy is feasible and safe. This approach offers an inherent cosmetic advantage and few postoperative discomfort. Additional experience and continued investigation are warranted.
