Ureterolitotomía laparoscópica con incisión única transumbilical

introduction: 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. material and method: a 29-year-old woman presented with chronic right lumbar pain and a 1.2cm 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. results: ureterolithotomy was successfully completed, with all the operative steps performed transumbically. operative time was 180minutes. no single-port device or articulating and bent instruments were utilized. estimated blood loss was less than 50ml. no intraoperative, access-related and postoperative complications took place. the duration of hospitalization was 24hours and scarless appearance was observed on postoperative day 15. conclusion: 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.
