Nonrefluxing ureteroileal cystoplasty for bladder augmentation or replacement of ureters: long-term results of own technique.

The technique of a nonrefluxing end-to-end ureteroileal anastomosis is described. The conjoined ends of both ureters are formed into a 4 to 5 cm. long ureteral tube that is placed loosely into the bowel lumen. Increased intraluminal pressure during micturition closes the valve by compressing the ureter wall from outside, thus, preventing reflux. An end-to-end enteroureteral anastomosis has been used in 32 ileal or colon conduits and in 6 patients with ureteroileal cystoplasty. The followup (range 1 to 15 years) of these 6 patients who underwent bladder augmentation or ureteral replacement is presented. Based on this experience, this type of anastomosis appears to be fast and safe, without urine leakage, stenosis or reflux. The nonrefluxing safety valve mechanism makes this anastomosis applicable for bladder augmentation, with no ill-effects and good long-term function.
