输尿管镜气压弹道碎石治疗输尿管结石(附116例报告)

目的：总结输尿管镜气压弹道碎石治疗输尿管结石的疗效。方法：回顾性分析116例采用输尿管镜气压弹道碎石治疗的输尿管结石患者资料。男49例，女67例；平均年龄43岁。结石位于输尿管上段3例，中段24例，下段68例。肾结石ESWL后形成输尿管石街21例。结果：碎石成功率90％(104／116)，其中一次碎石成功者85％(99／116)。术中置镜失败3例，发生输尿管穿孔4例。94例随访1～18个月，术后1个月内结石排净91例。KUB加IVU检查未发现输尿管狭窄。结论：输尿管镜气压弹道碎石治疗输尿管结石创伤小、成功率高、并发症少。

Transureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi(report of 116 cases)

Objective To evaluate transureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods 116 cases of ureteral calculi treated with ureteroscopic pneumatic lithotripsy from Dec.1999 to Feb.2002 were studied retrospectively.There were 49 male patietns and 67 female with an average age of 43,3 being upper ureteral stone,24 middle and 68 lower ureteral stone.21 ureteral stone-street. Results The stone fragmentation rate was 90%(104/116),85%(99/116) of which being fragmented on the first treatment session.The main complications were failure to insert the ureteroscope in 3 cases and ureteral perforation in 4.94 cases were follow-up for one to eighteen months and 91 cases were stone free within one month.No ureteral stricture has been observed on intravenous urogram. Conclusions Treatment of ureteral calculi by transureteroscopic pneumatic lithotripsy has been safe, effective and less invasive.
