Morphological characteristics of sphincter zone glands of urinary bladder in different stages of postnatal ontogenesis

Methods of macromicroscopy and morphometry have been used to study sphincter zone glands by 54 total preparations of a urinary bladder received from corpses of people of different ages without any pathology of organs of urine-genital apparatus. The glands were painted by 0, 05% methylene blue solution and were investigated with the application of stereomicroscopic-binocular microscope MBS-9. Microscopic sections of sphincter zone glands in the thickness 5-7 microns were stained with hematoxylin-eosin, azure-2-eosin and with hematoxylin-picrofucsin by Van-Gizon technique. Sphincter zone glands are arranged firmly without dependence on age, length and width of initial department of glands of these zones. In postnatal ontogenesis size indices of sphincter zone glands have been essentially changed. These indices are equal for left and right ureter sphincter zone glands
