大功率钬激光经皮肾镜取石术治疗肾结石

目的探讨大功率钬激光经皮肾镜取石术治疗肾结石的有效性和安全性。方法应用大功率(60W:3·0J×20Hz)钬激光经皮肾镜治疗单纯肾盏或肾盂结石52例(平均结石直径3·1cm),肾盂肾盏多发结石36例(平均直径2·8cm),鹿角状结石24例(平均直径6·8cm)。记录碎石取石时间、结石取净率以及手术并发症。结果平均每次手术碎石取石时间44min,一次经皮肾镜取石术结石取净率为66%(74/112),总的取净率为89%(100/112);术后3例患者出现高热,无其他并发症。结论经皮肾镜下大功率钬激光治疗能快速粉碎结石,缩短手术时间,是治疗肾结石的安全、有效方法。

High-power holmium laser with percutaneous nephrolithotripsy for kidney calculi

OBJECTIVE: To assess the efficacy and safety of the high-power holmium laser with percutaneous nephrolithotripsy for kidney calculi. METHODS: The high-power (60 W: 3.0 J x 20 Hz) holmium laser with percutaneous nephrolithotripsy was performed on 52 patients with single kidney pelvic or calyceal stones (average stone diameter 3.1 cm), 36 patients with multi-kidney pelvic and calyceal stones (average diameter 2.8 cm), 24 patients with staghorn stones (average diameter 6.8 cm). The duration of stone surgery, stone-free rate and complication were assessed. RESULTS: The mean duration of stone surgery was 44 min, the stone-free rate was 66% (74/112) after the first session, 89% (100/112) at the end of session. 3 patients had high fever after percutaneous nephrolithotripsy, no other adverse events were noted. CONCLUSIONS: The high-power holmium laser with percutaneous nephrolithotripsy can fragments calculi quickly and reduces the length of time of operation. It is an effective and safe technique for kidney calculi.
