钬激光与气压弹道碎石术处理输尿管石街的效果对照研究

A Comparative Study of Pneumatic Lithotripsy and Holmium Laser Lithotripsy for Ureteral Stone Street

目的对比研究输尿管镜下钬激光与气压弹道碎石术治疗体外冲击碎石术(ESWL)术后输尿管石街的疗效和安全性。方法回顾性分析我院2001年9月至2008年9月78例输尿管石街患者的临床资料。其中46患者(LL组)采用钬激光碎石,32例采用气压弹道碎石术治疗(PL组)。结果LL组单次碎石率为97.8%,高于PL组的71.9%(P<0.01);LL组排净时间为10±2d,短于PL组的21±3d(P<0.05);LL组手术时间为32±5m in,短于PL组的45±6m in(P<0.05),术后并发症发生率LL组4.3%,明显低于PL组的9.4%(P<0.05)。结论输尿管镜下钬激光碎石术治疗输尿管石街安全有效。

Objective To compare the efficacy and safety of endoscopic pnumatic lithotripsy（PL） and endoscopic laser lithotripsy（LL） in the treatment of ureteral stone street. Methods The clinical data of 78 consecutive patients underwent endoscopic lithotripsy either with the Swiss Lithoclast pneumatic lithotripter （32cases） or with Ho：YAGlaser lithotripter（46 cases） for the treatment of ureteral stones From Sep. 2001 to Sep. 2008 were analyzed retrospectively. Results The stone-free rate after a single session of LL was higher than that of PL（97.8% vs 71.9% ,P 〈0.01 ） ,the operation time and average stonefree time of LL was respectively shorter than that of PL（ 32min vs 45m in, 10days vs 21days ,P 〈 0.01 ）, and the incidence of major complication in LL was much lower than that of PL（4.3% vs 9.4% ,P 〈0.05 ）. Conclusion LL has its advantage over PL in high efficiency of stone fragmentation and low incidence of complication and is an effective and safe treatment modality for ureteral stone street.
