Introduction: This study aimed to evaluate success and complications of laparoscopic transperitoneal ureterolithotomy at our center., Patients and Methods: From November 2008 until September 2011, 33 patients, including 22 men and 11 women, with a mean age of 45.3 years (range, 19-67 years), underwent laparoscopic ureterolithotomy at our center. Locations of stones were the upper, middle, and lower ureter in 29, 1, and 3 patients, respectively. Ten patients had a history of previous abdominal or pelvic surgery. Laparoscopic ureterolithotomy was performed via a transperitoneal approach. Complications and outcomes were evaluated., Results: Mean operation time was 85.48±15.11 minutes. Except for one stone migration and one conversion to open surgery, all the ureteral stones were extracted laparoscopically (94% success rate). A double J stent was inserted antegradely during the procedure and remained for about 1 month in all cases except in 1 patient in whom both antegrade insertion and ureteroscopic relocation were used. Postoperative hypercapnia was detected in a young patient, who recovered with conservative treatment. No visceral complication occurred. The mean hospital stay and the drain installation interval were 4.1 days (range, 3-9 days). The mean return to full activity was 11.91±4.65 days. Preoperative hydronephrosis resolved at follow-up ultrasonography (3 months later) in all patients except 2 cases, in whom intravenous pyelography showed no obstruction (memorial hydronephrosis)., Conclusions: Laparoscopic transperitoneal ureterolithotomy is a safe and effective treatment modality for skilled surgeons and a convenient option for patients. Challenges, such as lower ureteral stones, redo cases, and antegrade double J stent insertion, can be overcome by experience.
