[Ileal ureteroplasties].
When the ureter is extensively compromised, preservation of the kidney without recurring to external diversion may be attempted by a psoas bladder procedure, transureteroureterostomy, renal autotransplantation or ureteral substitution using the intestine. The first two are not always possible and transplantation is perhaps extremely disproportionate. We therefore recur to ureteral substitution using the intestine. Ureteral substitution may be partial or total, although it is recommended to preserve the upper segment of the lumbar ureter whenever possible. The procedure can be performed using the entire ileal segment with or without modelling to the appropriate thickness. Reducing the diameter of the ileal graft will enhance urine propulsion, reduce mucus secretion and improve antireflux dynamics. Nine cases of ureteral substitution are described herein. Treatment depended on the underlying pathology, extent of ureteral compromise and location. The techniques employed were ureteral substitution with or without modelling and ureteral substitution combined with a bladder repair procedure.
