[Intraluminal invagination technic for the incision of ureterointestinal stenosis].
OBJECTIVE
This paper describes the endoscopic incision of uretero-ileal anastomotic strictures by a combined approach (percutaneous antegrade and endoscopic retrograde) using the intraluminal invagination technique over a balloon dilatation catheter.


METHODS
The different steps of the surgical procedure of incision of the stenotic segment of different techniques of ureteroileal diversion (Bricker, Camey, ureterosigmoidostomy) are described in detail. Endoscopic images and those from the image intensifier are shown.


RESULTS
Of the 6 cases described herein, incision was achieved in 5 and in 1 case stenting of the stenotic segment could not be achieved.


CONCLUSIONS
Intraluminal invagination of the stenotic segment considerably facilitates endoscopic incision.
