应用输尿管肾镜气压弹道碎石术治疗输尿管结石

目的：探讨输尿管肾镜气压弹道碎石术治疗输尿管结石的临床疗效。方法：1999年11月--2003年2月，采用输尿管肾镜下气压弹道碎石术治疗输尿管结石189例。结果：189例输尿管结石中，183例一次碎石成功，成功率96．8％(183／189)，6例进镜困难(其中l例输尿管穿孔)，改开放手术。随访lO天--3月，平均1．3月，2月内结石排净率为99．4％(182／183)。结论：此碎石方法安全，效果确切，损伤小，痛苦小，可作为输尿管结石的首选治疗方法。

Treatment of ureteral calculi by pneumatic lithotripsy under ureterorenoscope

Objective To evaluate the clinical effect of pneumatic lithotripsy under ureterorenoscope in the treatment of ureteral calculi. Methods One hundred and eighty-nine cases of ureteral calculi were treated by ureterorenoscopic pneumatic lithotripsy between November 1999 and February 2003. Results Lithotripsy was performed successfully on one session in 183 cases,with a success rate of 96.8% (183 of 189).Conversions to open surgery were required in the remaining 6 cases because of unsuccessful entry of the ureterorenoscope (ureteral perforation in 1 case).Follow-up period ranged from 10 days to 3 months (mean, 1.3 months). Stones were entirely expelled in 182 cases of the 183 cases (99.4%) within 2 months after the procedures. Conclusions With minimal invasion and pain, this procedure is safe and effective for ureteral calculi, being probably the treatment of first choice.
