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.
