title: Ureteral anastomosis in the orthotopic ileal neobladder: comparison of 2 techniques.
abstract: OBJECTIVE
  The functional results and complications of 2 different ureteroileal anastomoses were evaluated in patients with bladder cancer undergoing radical cystectomy and orthotopic ileal bladder substitution.
  
  
  METHODS
  Between 1989 and 1995, 102 patients underwent creation of a low pressure neobladder. In the first 50 cases the ureteroileal anastomosis was created with a split-cuff nipple technique as an additional antireflux mechanism. In the next 52 cases the ureteroileal anastomoses were constructed via the direct end-to-side technique counting on the antireflux protection of the afferent tubular limb.
  
  
  RESULTS
  Stenosis occurred in 7 of the 100 ureters (6 patients) treated with the split-cuff nipple technique and 7 of 104 treated with a direct end-to-side anastomosis. This complication occurred more commonly in the left ureter (11 of 14 patients). Reflux was noted at cystography in 10 cases with the split-cuff nipple method and 12 with end-to-side anastomoses, and was symptomatic in only 3 patients. Four ureteral strictures were treated successfully with primary open repair. Percutaneous dilation and stenting were performed for 8 ureteral strictures: 2 cases were successful, 3 failed and 3 are unresolved.
  
  
  CONCLUSIONS
  We observed no differences between the antireflux split-cuff and end-to-side anastomoses with regard to stricture formation or ureteral reflux. Therefore, we do not believe that there is a need to create antireflux ureteral anastomoses due to the tubular afferent ileal segment and given that the reflux is asymptomatic in most patients. Strictures may be treated with percutaneous balloon dilation and stenting but open repair appeared to be more effective.
