[Replacement of the trigonum vesicae by silicone rubber in mini pigs (author's transl)]

Prostheses of the trigonum vesicae made of silicone rubber and covered with a textile layer were implanted in 18 mini pigs. Investigations were done in two series: in the first the prostheses were covered on the outside with a narrow woven textile layer, in the second with Dacron-velour. While the narrow woven textile-lined prostheses were rejected into the urinary bladder after a short period, the Dacron-velour-lined prostheses remained well attached to the bladder wall.
