[Morphological and histochemical analysis of mucous membrane transformation of the artificial urinary bladder].

The performed morphologic study of transformation mechanisms of the intestinal reservoir mucous membrane using modern immunochemical and histochemical methods revealed three morphologic phases of enteric epithelium adaptation; reactive-inflammatory, compensatory-protective and atrophic. Enteric urinary reservoir preserves the cambial apparatus typical for the enteric phenotype with an inherent apoptosis activity and proliferation which confirms a low level of tumor transformation risk.
