目的比较微创经皮肾镜取石术（MPCNL）与输尿管镜下碎石术（URL）治疗嵌顿性输尿管上段结石的疗效。方法分别用微创经皮肾镜取石术及输尿管镜下碎石术治疗嵌顿性输尿管上段结石47例，58例。回顾比较两种方法的疗效、并发症等。结果 URL组的平均手术时间、血红蛋白下降率及术后感染发生率均显著低于MPCL组，分别为(28±10) min vs (65±15) min(P<0.05)、(1.2%±0.14%) vs (6.4%±0.62%)(P<0.05)及10.3%vs21.3%(P<0.05)；MPCL组结石清除率及并发症发生率显著优于URL组，分别为96%vs 62.1%(P<0.01)及0 vs 5.2%(P<0.01)；其中URL组发生了输尿管穿孔2例。结论治疗嵌顿性输尿管上段结石 MPCNL安全，疗效好，清石率高，可作首选。

Objective To compare the treatment results between minimal y invasive percutaneous nephrolithotomy (MPCNL) and ureteroscope recessive lithotrity (URL) for impacted proximal ureteral stone. Methods Patients with impacted proximal ureteral stone were treated by MPCNL (47 cases) and by URL (58 cases), The ef icacy and complications of these two methods were compared retrospectively. Results:URL group was associated with shorter mean operative time (28±10) min vs (65±15) min(P<0.05), lower hemoglobin decrease rates (6.4%±0.62%)(P<0.05) and lower postoperative infection rate 10.3%vs21.3%(P<0.05). Nevertheless MPCL had higher stone clearance rates 96%vs 62.1%(P<0.01) and lower Incidence of complications 0 vs 5.2%(P<0.01). There was 2 cases of ureteral perforation in the URL group. Conclusion MPCNL,which was characterized by its safety,the high stone clearance rate could be the best choice for the treatment of impacted proximal ureteral stone.
