B超介导下微创经皮肾镜取石术治疗嵌顿性输尿管上段结石56例

56 cases of upper ureteral incarcerational calculi undergoing micro-trauma percutaneous nephrostolithotomy by type-B ultrasonic mediating

目的探讨B超介导下微创经皮肾穿刺取石术(MPCNL)治疗嵌顿性输尿管上段结石的疗效与安全性。方法采用B超介导下MPCNL治疗56例单侧嵌顿性输尿管上段结石。结果56例患者中,7例合并严重感染先行Ⅰ期经皮肾穿刺造瘘术,5～7d后行Ⅱ期经皮肾镜碎石术;49例行MPCNL,术后5d结石清除率为89.8%,术后1个月结石清除率为100%。结论B超介导下微创经皮肾穿刺取石治疗嵌顿性输尿管上段结石疗效显著。

[Objectives] To explore the effects and safety of micro-trauma percutaneous nephrostolithotomy （MPCNL） in treatment for upper ureteral incarcerational calculi by B-type ultrasonic mediating. [Methods] We applied MPCNL by type-B ultrasonic mediating to treat 56 cases with unilateral upper ureteral incarcerational calculi. [Resuits] In all 56 cases, 7 cases coexisting severe infection underwent the first phase percutaneous nephrostomy（PCN）, and the second phase MPCNL after 5-7 days;the calculi clearance of the residual 49 cases was 89.8 percent which underwent MPCNL; one month after the operation the rate was 100 percent. [Conclusion] The stone clearance of up- per ureteral incarcerational calculi undergoing the treatment of MPCNL by type-B ultrasonic mediating is high.
