The use of pure carbon stomata (Biocarbon) in urinary diversion.

A new synthetic material, Biocarbon, has the advantages of tissue compatibility and chemical inactivity, so that there is minimal salt sedimentation. Experiments with animals extending over a period of more than 2 years showed good healing after various surgical and urological operations. Biocarbon stomata were then used for vesicostomies in 6 patients. The period of follow-up has been months. We conclude that Biocarbon implants used for ureterocutaneostomies and for various conduit operations can improve tthe care of stomapatients.
