微创经皮肾穿刺取石术治疗上尿路结石的临床观察

目的探讨微创经皮肾穿刺取石术治疗上尿路结石的临床效果和安全性。方法将100例上尿路结石患者随机分为观察组和对照组，各50例，观察组采用微创经皮肾穿刺取石术，对照组采用膀胱下尿路径路输尿管镜取石术，比较二种方法的碎石成功率和结石排净等。结果观察组患者碎石成功率100％，一次结石清除率96％，明显高于对照组的78％和64％，二者差异均有统计学意义（P〈0．C5）。结论微创经皮肾穿刺取石术治疗上尿路结石具有结石排净率高、创伤小，以及患者身体恢复快、并发症少等优点，是治疗上尿路结石安全有效的方法。

Objective To explore the therapeutic effect and safety of minimally invasive percutaneous nephrolithotomy lithotripsy in upper ureteric tract calculi. Methods 100 patients with upper ureteric tract calculi were divided randomly into the intervention group （50 cases ） and the control group （50 cases ）, the patients were treated by minimally invasive percutaneous nephrolithotomy in the intervention group, the patients were treated by transurethral ureteroscopic lithortripsy in the control group, the clinical symptoms were recorded and the successful rate of lithotripsy and the stone - free rate were compared. Results The successful rate of lithotripsy was 100%, the stone -free rate was 96% in the intervention group, they were higher 78% and 64% respectively in the control group, there were significant difference （ P 〈 0.05 ）. Conclusion Percutaneous nephrolithotomy in treatment of upper ureteric tract calculi has high stone - free rate ,minimal invasion ,quick recovery ,less complications, and it is a safe and effective treatment for upper ureterie calculi.
