微创经皮肾镜治疗输尿管上段结石

Minimally invasive percutaneous nephrolithotomy for upper ureteral calculi

目的:探讨微创经皮肾镜取石术(Minimally invasive percutaneous nephrolithotomy,MPCNL)治疗输尿管上段结石的安全性和有效性。方法:对56例输尿管上段结石病例行微创经皮肾镜碎石术,术后作腹部平片,观察是否有结石残留。结果:在56例病例中,有53例手术成功,手术成功率为94.6%。成功的53例平均手术时间(59.8±20.1)min,住院时间6～9 d,结石清除率为100%。所有病例均未输血或出现其它严重并发症。结论:微创经皮肾镜治疗输尿管上段结石安全有效,对于肾积水较重、离肾盂近的输尿管上段结石可作为首选。

Objective：To evaluate the safety and feasibility of minimally invasive percutaneous nephrolithotomy（MPCNL） in treating upper ureteral calculi.Methods：56 patients with upper ureteral calculi were treated by the minimally invasive percutaneous nephrolithotomy.Abdominal plain films were obtained after operation and were searched for residual stones.Results： 53 procedures achieved success in all the 56 cases.The success rate was 94.6%.In the 53 successful cases,the mean operative time was 59.8（±20.1） min;the hospital stay was 6 to 9 days;the stone free rate was 100%.There was no blood transfusion or other serious complication in all the 56 cases.Conclusion：MPCNL is safe and effective to treat upper ureteral calculi and can be considered to be the first choice for upper ureteral calculi close to the renal pelvis with severe hydronephrosis.
