双导管法在输尿管狭窄硬性扩张中的临床应用

Clinical applications of rigid dilatation using double catheters method for ureteric stenosis

目的 探讨双导管法在输尿管狭窄硬性扩张中的临床应用价值.方法 对51例采用双导管法行硬性扩张的输尿管狭窄患者的临床资料进行回顾性分析.结果 51例患者中,输尿管镜成功通过狭窄段46例（90.2%）,所有病例术中均未见输尿管穿孔或撕裂.未成功通过狭窄段的5例患者中,留置双J管2例,行经皮肾镜碎石取石2例,二期行输尿管狭窄段切除再接1例.术后3个月复查超声,患者的肾积水情况均有不同程度缓解.结论 双导管法作为处理输尿管狭窄硬性扩张时的一种进镜技巧,其有效性、安全性肯定,值得推广.

Objective To evaluate the clinical applications of rigid dilatation using double catheter method for ureteric stenosis.Methods The clinical data of 51 ureteric stenosis patients who had underwent rigid dilatation using double catheters method were retrospectively analyzed. Results Among the 51 patients,the ureteroscopy successfully went through the stricture in 46 cases（90.2%）,and all patients had no ureteral perforation or laceration.Among the 5 patients in whom ureteroscopy did not go successfully through the stricture,2 cases were placed double J tube,2 cases underwent percutaneous nephrolithotomy,and 1 case underwent two stage ureteral stricture resection and religation.All patients were examined by ultrasound examination 3 months after the treatment,and the degree of hydronephrosis was partial remission. Conclusions The double catheters method is a safe and effective way for rigid dilatation for ureteric stenosis,and it is worth popularizing.
