Abstract

Percutaneous incision and balloon catheter dilation of the ureteropelvic junction (UPJ) was performed in nine patients with secondary UPJ strictures. In all patients, the UPJ was successfully dilated, and no immediate complications were encountered. After a postoperative follow-up period of 4-27 months, six patients showed marked improvement on excretory urograms. Three patients had recurrent obstruction after 3-18 months. The 66% success rate of percutaneous balloon dilation with or without endopyelotomy compares favorably with the success rate of open surgical repair of secondary UPJ strictures in adults.

摘要

对9例继发于输尿管肾盂连接部（UPJ）狭窄的患者实施了经皮输尿管肾盂连接部切开及球囊导管扩张术。所有患者的输尿管肾盂连接部均成功扩张，且未出现即刻并发症。经过4至27个月的术后随访期，6例患者的排泄性尿路造影显示有明显改善。3例患者在3至18个月后出现复发性梗阻。经皮球囊扩张术无论是否联合肾盂内切开术的成功率为66%，与成人继发输尿管肾盂连接部狭窄开放手术修复的成功率相比更具优势。
