title: Serous-lined extramural ileal valve as a new continent cutaneous urinary outlet: an experimental study in dogs.
abstract: A new technique for the construction of a cutaneous continent catheterizable outlet suitable for urinary reservoirs is presented. The technique entails the creation of an ileal reservoir outlet by implantation of a tapered ileal segment into a serous-lined extramural tunnel. The procedure was carried out in eight experimental dogs, and the results were compared with a control group of five dogs for which a nontunnelled tapered ileal outlet draining a similar reservoir was constructed. Clinical, radiological and urodynamic evaluation provided evidence that this new outlet is easily catheterizable. Its continence mechanism is more reliable than that of a simple tapered outlet.
