微创经皮肾镜下双频双脉冲激光碎石术治疗上尿路结石

目的:探讨微创经皮肾镜下双频双脉冲激光碎石术治疗上尿路结石患者的疗效及安全性.方法:回顾性分析2004年7月～2006年10月应用微创经皮肾镜下双频激光碎石术治疗115例上尿路结石患者的临床资料.结果:115例患者均单通道碎石,手术时间0.5～2.5 h,平均1.5 h,86例一次取净,20例二次取石,6例有数枚1～5 mm碎石残留于肾小盏,总结石取净率为94.8%,2例患者需术后输血.结论:微创经皮肾镜下双频激光碎石术是治疗上尿路结石安全有效的方法之一.

Minimally invasive percutaneous nephrolithotomy with the frequency doubled-double pulse laser in treatment of upper urinary calculi

Objective:To evaluate the feasibility and safety of minimally invasive percutaneous nephrolithotomy(MPCNL)with the frequency-doubled-double pulse laser in the treatment of upper urinary calculi.Methods:From July 2004 to Oct 2006,115 cases with upper urinary calculi were treated with MPCNL,the clinical data were retrospectively analysed.Results:They were all treated with single tract procedure,average operative duration was 1.5 h.The stone-free rate reached 94.8%,6 cases had a residual stone smaller than 0.5 cm.Two cases had massive hemorrhage after the procedure.Conclusions:MPCNL is safe and effective in the treatment of upper urinary calculi.
