输尿管镜下钬激光碎石术与气压弹道碎石术治疗输尿管结石的比较

目的：比较输尿管镜下钬激光碎石术与气压弹道碎石术治疗输尿管结石的有效性和安全性。方法:回顾性分析415例采用输尿管镜下钬激光碎石术214例和气压弹道碎石术201例治疗输尿管结石患者资料。结果:钬激光单次碎石率为95%(203/214), 高于气压弹道的69%(139/201) (P<0.01);钬激光碎石术平均结石排净时间为18d, 短于气压弹道碎石术的31d (P<0.01); 钬激光碎石术组术中无输尿管穿孔等并发症, 气压弹道碎石术组有3例发生穿孔。结论:输尿管镜钬激光碎石的疗效和安全性优于气压弹道碎石术, 是治疗输尿管结石的一种安全,高效的方法。

Comparative study of pneumatic lithotripsy and holmium laser lithotripsy for ureteral stones

Objective To compare the efficacy and safety of endoscopic laser lithotripsy (LL) and endoscopic pneumatic lithotripsy (PL) for ureteral stones. Methods We retrospectively analyzed the clinical data of 415 patients with ureteral calculi treated with endoscopic laser lithotripsy (n=214 ) and pnumatic lithotripsy (n=201 ). Results The overall successful fragmentation rate of all ureteral stones in a single session of the LL group was higher than that of the PL group (95% vs. 69%, P<0.01).The average stonefree time of the LL group was shorter than that of the PL group (18 days vs. 31 days, P<0.01 ). No complications such as perforation during the operation were observed in the LL group whereas 3 perforations occurred in the PL group. Conclusion LL has its advantage over PL in its better clinical effect for the stone fragmentation and low complication rate and is an effective and safe treatment for ureteral stones.
