手术致肾盂输尿管交界部闭锁的再手术治疗

目的：探讨复杂性肾窦内肾盂结石取石术后肾盂输尿管交界部闭锁的原因和再手术治疗方法。方法：对于9例复杂性肾窦内肾盂结石取石术后致肾盂输尿管交界部闭锁患者行输尿管和肾下极侧侧吻合术．并采用双J管和肾造瘘管双重支撑及引流。结果：9例手术均获得成功。随访6～36个月，IVU示9例患者经再手术所重建的上尿路均引流通畅，肾盂肾盏积水明显缓解，肾功能明显改善。结论：输尿管与肾下极吻合是肾盂输尿管交界部闭锁再手术治疗的较好方法，而双J管和肾造瘘管双重支撑引流则是手术成功的关键。

Reoperation to cure the atresia at the ureteropelvic junction resulted from operation

Objective:To evaluate the causes of atresia at the ureteropelvic junction after the operation of intrasinusal pelviolithotomy and the method of reoperation.Methods:Nine patients who suffered from atresia at the ureteropelvic junction all underwent ureterocalicostomy, the Double-J catheter and nephrostomy tube were used to sustain and drainage.Results:All operation were successful. 9 patients were followed up from 6 to 36 months, a good drainage and the improvement of renal function were found in all patierts.Conclusions:Ureterocalicostomy may be the best surgical treatment for ureteropelvic junction atresia, and the sustain and drainage of the Double-J catheter and nephrostomy tube may be the key of the successful operation.
