Salvaging the iatrogenic megaureter.
From 1965 through 1975 we treated 30 children with 44 megaureters that were acquired after the reimplantation of normal caliber ureters. One-third of these children had had at least 2 prior surgical procedures on the bladder and 30 per cent were azotemic. There was no difference in the salvage rate of acquired megaureters with reflux versus obstruction. Temporary proximal diversion often was useful in the short-term management. Only 70 per cent of the patients completed reconstruction and only 70 per cent of those reconstructed were successful by all parameters. Ureteral tailoring was generally a necessary adjunct to successful repeat reimplantation. There was a significantly lesser salvage rate in those ureters that had had more than 1 prior surgical procedure. The best results were obtained when all surgical maneuvers were done transvesically because there was a significant incidence of acquired atonic vesical dysfunction after repeated dissections in the perivesical area.
