[Ileal loop stenosis: a cause of ilealconduit deterioration (author's transl)].
23 children underwent ileal loop urinary diversion between 1964 and 1974. They were 1977 reexamined after an average follow-up of 7 1/2 years. 7 of 22 children were found to have developed a stricture of the ileal loop. The diagnosis of conduit stricture rests primarily upon a tailored infusion urography and may be supplemented in exceptional cases by a low pressure loopogram. The radiographic and endoscopic features of the conduit stricture are presented. This entity usually develops late and silently. A review of the literature shows that the constant urinary exposure of the small bowel results in inflammatory and degenerative changes. The etiology of the conduit stricture has been attributed to these changes. This hypothesis is open to criticism as the entire bowel segment undergoes inflammatory degeneration. In our cases, the stricture always developed at the level of either the left or the right ureteroileal anastomosis. For this reason, a localizing factor has to be taken into account: This could be the usually performed retro- peritonealization of the ureteroileal anastomosis and/or the permanent though minimal traction of a too short ureter which has been divided too high in the pelvis.
