Endoscopic transvesical ureterotomy.
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.
