[Pre-peritoneal trans-ileal uretero-cutaneostomy. Apropos of 41 cases].

In the last 15 years we have used a modified version of the classic Bricker for external urine derivation in 41 cases (32 cases of neurobladder and 9 cancer of the bladder). This modification essentially involves placing the ileal loop in front of the peritoneum, in a superficial position which facilitates urethroileal anastomosis especially when trying to prevent reflux. The positioning of the loop greatly reduces urine stasis and ureteral stenosis, which in the classic Bricker is due to the ureter crossing the meso. We hope this technique will be used more widely in view of the excellent results obtained (low morbidity with hardly any complications).
