[Lumbar ureteral fistula after aortobifemoral bypass in a patient with ileal conduit and pelvic irradiation].

Contribution of a complex case of lumbar ureteral fistula with secondary abscess after aortobifemoral bypass in a patient with a background of radical cystectomy with ileal conduit and pelvic radiotherapy. A nephrostomy was established and the retroperitoneal collection was drained so that in a second phase ureteral replacement with ileum could be performed using uretero-ileal terminoterminal and ileum-ileal terminolateral by-pass with good therapeutic and functional results.
