逆行法介入治疗输尿管良性狭窄

目的探讨输尿管良性狭窄的介入治疗方法及疗效。方法对19例患者20处输尿管良性狭窄病变行球囊扩张并放置双猪尾输尿管支架。结果16例成功,3例失败。失败者1例为迷走血管压迫,1例为纤维索带压迫,1例为输尿管极度迂曲致导丝插入失败。16例成功者经静脉肾盂造影及B超复查显示肾盂积水逐步缓解,肾功能改善,2例输尿管支架尾端进入输尿管内形成医源性异物,后经输尿管镜取出。结论输尿管良性狭窄的介入治疗具有创伤小、操作简单等优点,为输尿管良性狭窄的患者提供了新的治疗方法。

Retrograde interventional technique for benign ureteral strictures

Objective To discuss interventional treatment technique for benign ureteral strictures. Methods A total of 19 cases with 20 benign ureteral strictures were treated with balloon dilatation and double-pigtail ureteral stent placement. Results Among 19 caces,16 were succeeded in a rate of 84.2%.The three failure cases included one of compression by aberrant vessels,one by compression of fibrous-strings and the last one due to tortuosity of the ureter.Re-examinations,by intravenous urography and B ultrasound were carried out in 16 successors,showed gradually release of hydro-nephrosis and renal function improvement.Iatrogenic foreign body ocurred in 2 cases,caused by the protruding tail of stent which had been taken out under ureteroscopy. Conclusions Interventional technique for benign ureteral strictures possesses adventages with mild injury,simple operation,and a new effective method.
