INTRODUCTION: Retroperitoneal laparoscopic ureterolithotomy is a new option to treat upper and middle ureter calculi in selected patients. However, migration of the stone and the flow of urine will influence the success. METHODS: We have developed a new and practical method using a clamp proximally above the stone to fix its position and prevent urine flow. Twenty patients had undergone retroperitoneal laparoscopic ureterolithotomy using this method. A bulldog artery clamp was used as the temporary clamp and was placed at the proximal part of the ureter during the procedures of incision, intubation and suture. RESULTS: The average age of the patients was 42.5 years (range: 26-73) and the average stone size was 13.7 mm (range: 10-28). The average operating time was 38.2 min (range: 30-85). All target stones were successfully extracted without major complications. The average time of post-operation drain removal was 1.5 days. No case of prolonged urine leakage or ureter stricture was recorded. CONCLUSIONS: We conclude that using a temporary ureter clamp is a feasible and practical method to fix the stone and minimize the difficulty of retroperitoneal laparoscopic ureterolithotomy.
