Ileal interposition for the treatment of a long gap ureteral loss

We retrospectively reviewed 10 patients (7 males and 3 females) who were treated with ileal interposition for long gap ureteral loss between 1989-1995. The mean patient age was 42 years old (35-52), mean ureteral gap was 18 cms (10-25). The etiology of ureteral loss included: 4 retroperitoneal fibrosis, 2 recurrent stone, 2 after pancreatitis and its complication and 2 after ureteral injury. The mean follow-up was 4 years (2-7). The post operative course was uneventful with no immediate and long term complications detected and there was no metabolic problem. Only asymptomatic bacteriuria in 5 cases (50%) was noted but it was not clinically significant.
