Endoscopic transvesical ureterotomy was used in 2 cases of lower ureteral stricture. Ureteral catheterization was performed after dilation. Then, with cutting diathermy a Colling's knife was directed so that an incision was made at the 12 o'clock position, cutting onto the catheter and, thus, completing the ureterotomy. In each case the incision extended outside the bladder through the strictured segment of the ureter and above to the dilated ureter proximal to the stenosis. Obstruction was relieved in both cases and, although vesicoureteral reflux was present during voiding, excretory urography at 12 months demonstrated acceptable tracts.
2例输尿管下段狭窄患者采用了经膀胱内镜输尿管切开术。扩张后进行输尿管插管。然后，使用切割透热法将科林氏刀定向，在12点位置做切口，切入导管，从而完成输尿管切开术。在每例患者中，切口经输尿管狭窄段延伸至膀胱外，并向上延伸至狭窄近端扩张的输尿管。2例患者的梗阻均得到缓解，尽管排尿时存在膀胱输尿管反流，但12个月时的排泄性尿路造影显示尿路情况尚可。
