摘要目的 比较经输尿管镜气压弹道碎石术与钬激光碎石术治疗输尿管结石的疗效和安全性。方法 总结应用输尿管镜技术治疗285例输尿管结石患者的临床资料，其中气压弹道碎石术145例，钬激光碎石术140例。结果 钬激光碎石术单次手术碎石率为95.7%，高于气压弹道碎石术的69.7%，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；钬激光碎石组无明显并发症发生，气压弹道碎石组有5例发生穿孔。结论 钬激光碎石术的有效率和安全性优于气压弹道碎石术。钬激光碎石术是治疗输尿管结石的一种安全、高效的方法。

abstractsObjective To compare the efficacy and safety of endoscopicpnumatic lithotripsy (PL) and endoscopic laser lithotripsy (LL) for ureteral stones.Methods From Aug.1994 to Feb.2000,285 consecutive patients underwent endoscopic lithotripsy either with the Swiss Lithoclast pneumatic lithotripter (145 cases) or with Ho:YAG laser lithotripter (140 cases) for the treatment of ureteral stones.Results The single session overall successful rate of stone fragmentation of LL was higher than that of PL (95.7% vs,69.7%,P<0.01).The average stonefree time was shorter for LL (18 days vs.31 days,P<0.01).No major complication has been observed in LL whereas 5 perforations were encountered in PL.Conclusions LL has its advantage over PL in high efficiency of stone fragmentation and low complication rate and is an effective and safe treatment modality for ureteral stones.
