后腹腔镜输尿管上段复杂性结石切开取石术中结石移位的预防与处理

目的 探讨后腹腔镜输尿管上段复杂性结石切开取石术中结石移位的预防与处理。方法 回顾性分析13例复杂性输尿管上段结石行后腹腔镜输尿管切开取石术中结石移位患者的临床资料。结果 10例结石移位入肾盂，2例结石移位入肾上盏，1例移位入肾中盏。10例患者使用套石篮取石成功，3例患者使用输尿管软镜取出结石。结论 直接套石篮取石，必要时使用输尿管软镜可以有效处理后腹腔镜输尿管上段复杂性结石切开取石术中结石移位。

Prevention and management of the calculus drift in retroperitoneoscopic ureterolithotomy for complex upper ureteral calculus

Objective   To investigate the prevention and management of the calculus drift in retroperitoneoscopic ureterolithotomy for complex upper ureteral calculus．Methods  The clinical data of 13 cases of the calculus drift in retroperitoneoscopic ureterolithotomy for complex upper ureteral calculus were retrospectively analyzed．Results   Stones drifted into the renal pelvis in 10 cases, while stones drifted into the upper calyx in 2 cases and stone drifted into the middle calyx in 1 case．Stones were removed by stone basket successfully in 10 cases, while stones were removed by flexible ureteroscopy in 3 cases．Conclusions   Stone basket, when necessary, flexible ureteroscopy can be used to deal with the calculus drift in retroperitoneoscopic ureterolithotomy for complex upper ureteral calculus effectively．
