No cases of material rejection or postoperative period complications were detected. At all stages the xenopericardium preserved structural integrity and served as a skeleton for forming an adequate UB wall. Small peripheral areas were exposed to lysis. After 3 months the collagen structure of the graft was rearranged and mucous membrane epithelization appeared. Folding was already formed and invasion of narrow SMC panniculi was registered within deeper layers. After 6 months the inner surface of the UB wall consisted of normal mucosa, lined by fully formed epithelium.
