[Endoscopic dilatation of ureteroileal stenosis in Bricker diversions. Apropos of 11 patients].

Eleven patients with stenosis of an uretero-ileal anastomosis following Bricker's operation underwent endoscopic dilatation of these stenoses via an inferior approach with Eder-Puestow's apparatus or Savary's dilators. The preliminary results were favourable in 7 patients with clinical, endoscopic and radiological improvement. An uretero-ileal drainage catheter was inserted in each case and was changed regularly after the operation. In one patient, a stone trapped in the anastomosis was able to be removed via the endoscopic procedure. No complications were observed. The two technical failures required surgical re-operation in one case and dilatation via a superior approach with an inflatable balloon catheter. This technique demonstrates the value of gastrointestinal endoscopy in the treatment of certain complications in patients with a urinary diversion using a segment of the intestinal tract.
