title: The augmented rectal bladder for urinary diversion: experience with the original valved rectum and a valve-less modification.
abstract: Kock's augmented and valved rectum was created in 10 patients following total cystectomy. During an observation period of up to 46 months, 4 patients died (1 from a recurrence of cancer, 1 from multiple organ failure subsequent to diabetes mellitus, 1 from coronary insufficiency, and 1 from cerebral hemorrhage). Post-operative complications included valve failure in 1, hydronephrosis in 2, and mild nocturnal urinary incontinence in another. Hyperchloremic metabolic acidosis was particularly notable in the cases without an intussuceptive valve of the rectum. Their base excess ranged from -6.9 to -15.0 mM/l but the condition was satisfactorily controlled by oral administration of alkaline agents. Although the present method has a number of shortcomings, the absence of a stoma and elimination of the need for self-catheterization are outstanding benefits. For these reasons, we believe that it is an effective option for urinary diversion.
