Abstract INTRODUCTION: Our aim was compare of two types of lithotripter include holmium: YAG laser and pneumatic one in transurethral ureterolithotripsy (TUL) for the management of ureteral calculi ≥۱ cm.METHODS: ۱۱۲ patients with ureteral calculi more than ۱ cm were selected in randomized order for pneumatic or holmium: YAG laser transurethral ureterolithotripsy (۵۶ patients in each group). Ultrasonography and intravenous urography were performed for all patients before surgery. Complete clearance and success was defined as the absence of any fragments on post operation KUB and ultrasonography images.RESULTS: Success rate was ۸۵.۷% in pneumatic group and ۱۰۰% in holmium: YAG laser group (p =۰.۰۰۳). Stone migration up in the pelvicalyceal system was observed only in ۸ cases of pneumatic group. No statically differences were observed in terms of patient’s age, hospital stay, and complications between two groups.CONCLUSION: According to our experience, for ureteral stone larger than ۱ Cm treatment with ureteroscopy and laser lithotripsy is a preferring approach with favorable operation time and hospital admission, and no more significant complication.
