I have reviewed our own experience with the ileal bladder and with cecal and cecoileal reservoirs, along with the reported experiences of other investigators. Both of these major classes of diversion offer continent nonrefluxing storage of urine. I advise patients who are candidates for either type of procedure to weigh the prospect of urethral voiding (but enuresis with the ileal bladder) v a continent abdominal stoma that requires self-catheterization of variable difficulty with a cecoileal reservoir. The perfect urinary diversion does not exist. Greater experience in time and numbers is required to know if the newer procedures reviewed here are even as good as the ileal conduit. However, the potential for greater preservation of renal function and significantly improved quality of life cannot be denied.
