[Partial replacement of the ureter with lyophilized human dura mater. Experimental research (author's transl)].

In order to evaluate whether and how for lyophilized human dura mater deserves to be used in the field of ureteral alloplastic surgery, the authors present and discuss the results they obtained during the course of experimental research. In the light of their personal histological documents, they stress the absence of reject phenomena, a property which, together with the absence of precipitates, the complete reepithelialisation of the transition epithelium and the ability to ensure normal ureteral perviousness, evidences that lyophilised human dura mater has full rights to a place in substitutive surgery of a segment of ureter, in particular the lumbo-liiac segment.
