[The endoscopic section of ureterosigmoid stenosis].
OBJECTIVE
Herein we describe the technique of endoscopic incision in the treatment of ureterointestinal stricture.


METHODS
A teflon sheathed stent is placed in the stenotic ureterointestinal segment utilizing a combined approach (percutaneous antegrade endoscopic transrectal) and a balloon is passed over the stent retrogradely. The balloon is then inflated and is pulled retrogradely to invaginate the anastomosis into the rectal lumen. Thereafter, endoscopic incision of all the layers and the entire length of the stricture is performed by electrocautery.


RESULTS
The radiological evaluation three months postoperatively show marked morphological and functional improvement of the compromised renal unit.


CONCLUSIONS
In patients with a ureterointestinal urinary diversion, endoscopic incision of the stricture at the site of the anastomosis is a valid therapeutic technique, after discarding the presence of urinary infection or tumor at this site. Furthermore, open surgery can be done in the event this technique fails to achieve the desired results.
