输尿管镜气压弹道碎石术治疗尿路结石

目的：探讨输尿管镜气压弹道碎石技术治疗尿路结石的疗效。方法：采用输尿管镜气压弹道碎石治疗尿路结石780例。结果：780例中760例一次碎石成功，治疗成功率为97．5％。其中输尿管上段结石成功率为90．6％，中段为93．9％，下段为99．6％，膀胱、尿道结石为100％。平均碎石时间为（5．0±3．0）min，术后碎石排净率为98．2％。结论：该方法结石排净率高，创伤轻微，手术并发症少，是治疗尿路结石较为理想的治疗方法之一。

Transureteroscopic pnenmatic lithotripsy in the treatment of urinary calculi

Objective:To evaluate transureteroscopic pneumatic lithotripsy in the treatment of urinary calculi. Methods: 780 cases of urinary calculi were treated with ureteroscopic pneumatic lithotripsy. Results:760 patients were stone free after treatment and the success ratio was 97.5% . The success ratio upper ureteral calculi was 90.6% , middle are teral calculi was 93.9%, distal ureteral calculi was 99.6%, bladder an urethra calculi was 100%. Mean pneumatil lithotripsy time was (5.0 ±3.0) min, the total stone-free rate was 98.2%. Condusion: This combined treatment has high stone-free rate with minimal invasion and less complications and is an ideal treatment for urinary calculi.
