[Repair of large vesical wall defects with lyophilized dura mater. Experimental research (author's transl)].

In order to evaluate whether and how far a fuller case documentation can contribute to a better knowledge of the real possibilities of the lyophilised human dura mater in the field of vesical alloplastic surgery, the Authors present and discuss the results they obtained during the course of experimental research. In the light of personal histological documents, they stress the absence of reject phenomena, a property which, together with the absence of precipitates, the complete re-epithelialisation of the transition epithelium and the possibility of ensuring good vesical capacity, evidence that lyophilised human dura mater has full rights to a place in repair surgery of large vesical wall defects.
