Ileal replacement of the bilharzial ureter: is it worthwhile?

Our 14-year experience with the use of isolated ileal segments for replacement of the bilharzial ureter is analyzed retrospectively. Of 52 patients subjected to this procedure followup data were available for 38, in whom 52 ureters were repaired. The results generally were unsatisfactory: the morbidity and mortality rates were high and the percentage of functional improvement was low. The risk was higher for patients with low creatinine clearance. Therefore, we recommend that this operation be avoided when possible. If the operation is unavoidable, tapering of the ileal segment with antireflux ileovesical anastomosis may improve the outcome. Further clinical study must be done.
