[Plastic closure of a bladder wall defect by use of a pedicled auto-alloplastic prosthesis in experiments].

The problems of substituting larger areas of the bladder wall are not definitely solved. Experiments on implantation of auto-allografts resulted in complications, which prevented correct epithelization of the interior surface, due to ischemia. In successful experiments on 34 rabbits, the authors obtained sufficient blood supply of the implantate and re-epithelization of the graft's interior surface in a two-stage operation.
