【摘要】：目的探討輸尿管鏡超聲碎石術中應用逆向順流沖洗攔截法治療輸尿管結石的優(yōu)越性和安全性。方法回顧性分析我院2013年3月~2017年2月72例輸尿管結石,分為觀察組和對照組,觀察組采用逆向順流沖洗攔截法超聲碎石術,對照組采用常規(guī)超聲碎石術,對2組手術療效及術后并發(fā)癥發(fā)生率進行比較。結果觀察組手術時間明顯短于對照組[(50.1±3.5)min vs.(59.9±4.5)min,t=-10.314,P=0.000];一次性碎石清石率明顯高于對照組[91.7%(33/36)vs.58.3%(21/36),χ~2=10.667,P=0.001];拔管后2周微結石(≤3 mm)排清率優(yōu)于對照組[97.2%(35/36)vs.75.0%(27/36),χ~2=7.432,P=0.006];術后發(fā)熱率明顯低于對照組[8.3%(3/36)vs.33.3%(12/36),χ~2=6.821,P=0.009]。結論在輸尿管鏡超聲碎石術中采用逆向順流沖洗攔截法能夠提高碎石清石率,安全可行,有較好的臨床推廣價值。
[Abstract]:Objective to study the advantage and safety of reverse-flow irrigation and interception in ureteroscopic ultrasound lithotripsy in the treatment of ureteral calculi. Methods 72 cases of ureteral calculi in our hospital from March 2013 to February 2017 were retrospectively analyzed and divided into two groups: the observation group and the control group. The observation group was treated with reverse flow flushing and intercepting ultrasound lithotripsy, while the control group was treated with conventional ultrasound lithotripsy. The effect of operation and the incidence of postoperative complications were compared between the two groups. 緇撴灉瑙傚療緇勬墜鏈椂闂存槑鏄劇煭浜庡鐓х粍[(50.1鹵3.5)min vs.(59.9鹵4.5)min,t=-10.314,P=0.000];涓，
