We tried to reconstruct partly or completely the urinary tract in nine patients who underwent, some years before, attempts at urinary diversion, for severe urinary tract diseases, using the intestine as an ureteral or a bladder subtitute. Our aim was to do a two-stage procedure, trying to reconstruct one normal side without the use of bowel, then within 6 mo to reevaluate the reconstructed side and, if correct, to do a transureteroureterostomy from the diverted side into the reconstructed side. Two patients were operated on this way and cured. We then advanced to a more aggressive approach with a one-stage procedure. Two more patients were operated on and cured. We then attempted reconstruction in patients when the ureter was no longer available. Two patients were operated on using a tapered and reimplanted piece of small bowel in the bladder and cured. Next we came to the patients in whom neither ureter nor bladder was available. Two patients were undiverted from an ileal loop and transformed into an ureterosigmoidostomy with transureterostomy, with achievement of continence. Finally, when neither ureter, nor bladder, nor even rectum was available, one patient on hemodialysis for a nonfunctioning Duhamel rectal bladder was converted into a functioning ileal loop and freed from dialysis. Technical points are discussed, focused on a two-stage procedure with one reimplantation and a transureteroureterostomy. When a permanent diversion must be done, today, for rare indications, we prefer to perform a sigmoid conduit.
