Carbon urinary conduits. Animal experiments.

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.

Experience with the Small-Carrion penile prosthesis in the treatment of organic impotence.

Since certain animals are endowed with an os penis the concept of using penile implants was a natural development. Herein we report on our experience with the Small-Carrion penile prosthesis in 23 patients. The surgical technique is described as well as several examples of postoperative results. The major complication encountered was infection. All patients were able to accomplish coitus without significant difficulty. Proper patient selection and the attitude of the sexual partner constitute the major factors in the ultimate success or failure of the procedure.
