目的　探讨输尿管镜下气压弹道碎石术治疗输尿管结石的临床疗效。方法　采用输尿管镜下气压弹道碎石术治疗输尿管结石 186例。结果　一次性结石粉碎率为 87.1% (16 2 /186 ) ;并发症发生率 3.2 % (6 /186 ) ,以输尿管穿孔和感染为主。结论　输尿管镜下气压弹道碎石术治疗输尿管结石疗效确切 ,安全 ,创伤小 Objective To investigate the clinical efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureteral calculi. Methods ureteroscopic pneumatic lithotripsy for ureteral calculi in 186 cases. Results Disintegration rate of disposable stones was 87.1% (16 2/186). The incidence of complications was 3.2% (6 of 186). The majority were ureter perforation and infection. Conclusions Ureteroscopic pneumatic lithotripsy is effective, safe and less invasive in the treatment of ureteral calculi
