U100双频激光和气压弹道碎石治疗输尿管结石的疗效比较

Compare the therapeatic effect of frequency-doubled-doubled-pulse laser and pneumatic ballistic lithotripsy for the treatment of ureteral calculi

目的：探讨U100双频激光治疗输尿管结石的优越性。方法：对经U100双频激光和气压弹道两种碎石方法治疗输尿管结石的疗效进行比较。结果：术后2～4周，U100双频激光碎石（双频激光组）结石排净率93．8％（167／178），气压弹道碎石（气压弹道组）为85.0％（267／314）；双频激光组结石回漂到肾盂发生率3．4％（6／178）．气压弹道组为6．7％（21／314）；双频激光组并发症相对较少，术后肉眼血尿发生率为31％，2例发生肾绞痛，无一例发生输尿管穿孔和泌尿系感染；而气压弹道组术后肉眼血尿发生率为53．2％，15例发生肾绞痛，4例发生输尿管穿孔，6例发生泌尿系感染。结论：U100双频激光输尿管碎石优于气压弹道碎石，是一种操作简单、安全、对软组织损伤小、碎石高效的输尿管结石治疗方法。

Objective： To investigate and compare the therapeutic effect of frequency-doubled-doubled-pulse laser and pneumatic ballistic lithotripsy for the treatment of ureteral calculi. Methods： To comparatively study the stone-free rate, cure rate and complication of the two methods for treatment of ureteral calculi. To summarize the advantages and disadventages of the two treatment. Results： stones were thoroughly removed from the ureter in 178 patients in frequency-doubled-doubled-pulse laser group with low complication, the stone-free rate was 93. 8% （167/178） in post-operative 2-4 weeks. 314 patients in pneumatic ballistic lithotripsy group, of which 267 patients were successfully cured. The stone-free rate was 85.0% （267/314） in post-operative 2-4 weeks, but with high complication. Conclusions： The frequency-doubled-doubled-pulse laser for the treatment of ureteral calculi is markedly surpassed the pneumatic ballistic lithotripsy, and is a safe, high-performance approach for treatment ureteral calculi.
