Continent urinary diversions are currently gaining wide acceptance as alternatives to the ileal conduit following cystectomy for neoplasm or bladder dysfunction. Clean, intermittent catheterization of the reservoir (pouch) at regular intervals obviates the inconvenience of wearing an external stomal appliance. A variety of surgical techniques have been described for continent pouches. These techniques make use of the small bowel alone (Camey and Kock techniques) or a combination of cecum and terminal ileum (Indiana, Mainz, Penn, and King techniques). The optimum pouch protects the upper tracts by prevention of reflux, provides urinary continence, and has sufficient capacity to require catheterization no more frequently than every 3-6 hours. Simplified construction techniques for the commonly encountered pouches are graphically presented, and a method is suggested for the study of continent diversions.
