Maxi-pouch: a new technique for ileal conduit conversion to continent urinary reservoir.

We present an alternative technique for conversion of an ileal conduit to a continent urinary diversion that uses a combination of ileal and ileocolonic substitutions. Filling pressure studies and radiography of the pouch, endoscopy and excretory urography revealed a reservoir capacity of 850 cc, no reflux, normal urinary tracts and no uninhibited contractions. In complex cases of neuropathic and nonneuropathic bladders or patients who have undergone cystectomy and have an unacceptable lower urinary tract for undiversion, we propose this technique of continent urinary reservoir as an alternative.
