title: Carbon urinary conduits. Animal experiments.
abstract: A new type of urinary conduit utilizing pure carbon has been used in dogs. It appears to be inert with respect to urine, acts as an adequate conduit in dogs, and theoretically should work in humans. Twelve vesicostomies and two ileal-bladder using carbon as a conduit were performed in dogs. Evaluation of the biocompatibility of the carbon material, a report on the experimental animal testing procedures showing protocol and results, and detailed description of the surgical technique are shown. Carbon conduits, so designed, functioned well and should be tolerated in humans as long term urinary conduits obviating the need for indwelling catheters and bulky adhesive dressing.
