Ureteral reconstruction and bypass: experience with ileal interposition, the Boari flap-psoas hitch and renal autotransplantation.

A total of 18 patients underwent an operation for extensive ureteral loss from 1980 to 1986. The indications included recurrent calculi, retroperitoneal fibrosis, surgical trauma and tumor. Of the patients 10 had construction of an ileal ureter (4 had bilateral reconstruction), 6 had creation of a psoas hitch with a Boari bladder tube and 2 were treated by autotransplantation. Mean duration of followup was 4.8 years. The procedure was successful in 17 patients. There were no apparent differences among the groups. Selection criteria and potential complications are discussed with regard to each technique. These procedures provide an excellent means for reconstruction of the urinary tract in patients who have failed other treatments.
