直孔输尿管导管在腔镜手术中协助留置双J管的应用

目的 探讨直孔输尿管导管在腔内泌尿外科手术中协助留置双J管的效果。方法 回顾性分析了自1998年以来40例直孔输尿管导管协助下留置双J管的资料。其中26例肾结石在ESWL前，3例在腹膜后腔镜输尿管上段切开取石术时，8例因肿瘤浸润输尿管致恶性梗阻，借助直孔输尿管导管经膀胱镜逆行留置双J管。3例M-PCNL术中常规方法置管困难，改用直孔输尿管导管协助留置双J管。结果 97．5％成功置人双J管。结论 直孔输尿管导管协助留置双J管，具有操作简单、高效安全、能提高置管成功率、缩短置管时间，值得临床推广。

Application of indewelling double J tube asisted by straight pore ureteral catheter in endourology

Objective To study the effects straight pore ureteral catheter in the management of indewelling double J tube in endourology.Methods From January 1998 to August 2004, The clinical data of 40 cases underwent double J tube by straight pore ureteral catheter were analyzed retrospectively. Among them, the double J tube was inserted in 26 cases with renal caculi before ESWL,3 cases with ureter calculus during retroperitioneoscopic ureterolithotomy and 8 cases with malignant ureteral obstruction were inserted double J tube by cystoscope. 3 cases with renal caculi in M-PCNL were inserted double J tube by ureteroscope.Results The successful rate inserted double J tube was 97.5%.Conclusion Double J tube can be indwelled easily and safely asisted by straight pore ureteral catheter.
