微创经皮肾镜钛激光碎石术治疗输尿管上段结石的效果分析

Effect of minimally invasive percutaneous nephrolithotomy titanium laser lithotripsy for upper ureteral calculi

目的：分析微创经皮肾镜钛激光碎石术（MPCNL）治疗输尿管上段结石的临床效果。方法68例输尿管上段结石患者按数字表法随机分为研究组34例和对照组34例。研究组给予 MPCNL 治疗，对照组给予体外冲击波碎石术（ESWL）治疗，比较两组的治疗效果。结果研究组一次碎石成功率、结石清除率分别为91．18％、91．18％，均高于对照组的70．59％、67．65％，两组差异均有统计学意义（χ2＝4．660、5．757， P ＝0．031、0．016）。结论微创经皮肾镜钛激光碎石术用于输尿管上段结石的治疗中，可取得良好的治疗效果。

Objective To analyze the clinical effect of minimally invasive percutaneous nephrolithotomy titanium laser lithotripsy（MPCNL）on upper ureteral calculi.Methods According to digital table,68 patients with upper ureteral calculi were randomly divided into the study group and control group,cach group in 34 cases.The study group received the MPCNL treatment,the control group received extracorporeal shock wave lithotripsy（ESWL）therapy. The therapeutic effects were compared.Results The success rate of gravel,stone clearance rates of the study group were 91 .1 8% and 91 .1 8%,which were higher than 70.59%,67.65% of the control group,there were significant differences between the two groups（χ2 =4.660,5.757,P =0.031 ,0.0164）.Conclusion Percutaneous nerve titanium laser lithotripsy for upper ureteral stones can achieve good therapeutic effect.
