title: [Epithelial tumors of the urinary bladder].
abstract: Morphological, electron-microscopy, and histochemical investigations of the normal human mucous membrane of the bladder and 450 vocus epithelial tumours of the same localization were carried out, which made it possible to work out additional criteria for determining the degree of differentiation of tumourous cells. The structural-functional features of tumourous cells observed were used as histochemical and ultrastructural markers of the degree of maturity of different transitional-cell tumours and were taken into account in the course of the development of the pathoanatomic classification of epithelial tumours of the bladder in man.
