输尿管镜气压弹道碎石328例报告

目的评价输尿管镜气压弹道碎石在输尿管结石治疗中的应用价值。方法回顾性分析2001年7月￣2005年10月应用输尿管镜气压弹道碎石治疗328例输尿管结石患者的治疗情况。男性188例,女性140例,平均年龄38岁,10例结石位于输尿管上段,96例位于中段,还有222例位于下段,有11例是在ESWL碎石治疗后形成的石街。采用德国Wolf8.0/9.0F输尿管镜和APL气压弹道碎石机经尿道置镜碎石。结果该组输尿管结石一次碎石取净88.5%(290/328)。主要并发症为置镜失败(13例)和输尿管穿孔(6例),对288例患者随访了1￣18个月,其中266例在术后3个月内结石完全消失,术后影像学检查没有明显的输尿管狭窄发生。结论应用输尿管镜气压弹道碎石治疗输尿管结石具有高效、微创、安全的特点,是中、下段结石治疗的首选方法。

Transureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi (report of 328 cases)

Objective To evaluate transureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods 328 cases of ureteral calculi treated with urteroscopic pneumatic lithotripsy from 2001 to 2005 were studied retrospectively. There were 188 male and 140 female patients with an average age of 38, 10 with upper ureteral stone, 96 with middle and 222 with lower ureteral stone, 11 ureteral stone street. Results The stone fragmentation rate was 88.5% (290/328). The main complications were failure to insert the ureteroscope in 13 cases and ureteral perforation in 6. 288 cases were follow-up for one to eighteen months and 266 cases were stone free in three months. No significant ureteral stricture has been observed on intravenous urogram. Conclusions Treatment of ureteral calculi by transureteroscopic pneumatic lithotripsy has been safe, effective and less invasive and should be the first choice to the patients with middle and low ureteral stones.
