腔内技术治疗输尿管狭窄

Endoscopic management of ureteral stricture

为了提高腔内技术治疗输尿管狭窄的效果，从１９８４年６月至１９９５年７月应用腔内技术治疗输尿管狭窄１６例。其中行气囊扩张７例、硬性扩张７例、膀胱镜下输尿管壁段切开加扩张２例，对扩张后复发２例行腔内输尿管切开加扩张治疗；扩张失败３例（２例为先天性ＵＰＪ狭窄，１例为ＥＳＷＬ后长段输尿管狭窄）行开放手术治疗。术后随诊８个月至７年，腔内技术治疗成功率为８１．３％，治愈率为７５．０％，好转率为６．３％，失败１８．７％。认为扩张治疗可作为输尿管狭窄的首选治疗方法，疗效不佳或复发者可再次扩张治疗，或行腔内输尿管切开加扩张治疗；以上方法也可作为输尿管狭窄开放手术失败的补救措施。

From June 1984 through July 1995, endoscopic manipulation was carried out for 16 cases of ureteral stricture,ballon catheter dilatation for 7,rigid plastic stent dilatation for 7, incision and dilatation of the intravesical segment of ureter via cystoscopy for 2. Stricture recurred in 2 and was again treated by endoureterotomy with dilatation. The cure rate was 75% (12/16),being improved in another while failure occurred in 3. Endoureteral dilatation was recommanded as the treatment of choice for ureteral stricture as well as for reccurrent cases. Endoureteral incision with dilatation could be carried out if necessary.
