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

The research goal is to study functional condition of upper and lower urinary tracts at fetus with obstructive uropathy and development of differential diagnostic and prognostic criteria of transition of functional disorders to organic. The diagnosis of prenatal and verified postnatal obstructive uropathy at 42 fetuses has been made by prenatal ultrasonic cystometry. Process of filling and evacuation of bladder has been under study. Obtained data have been compared with the results of dynamic measurement of kidney sizes in a standard projection. According to the results only at 19,1% of cases statistically significant urodynamic differences have not been revealed in comparison with control group. Diagnostic accuracy of organic form of urodynamic obstructions is 84%, of functional in 64,7% of observations and in 52,9% of cases the infection of urinary tracts with incomplete evacuation of bladder has been diagnosed. The degree of kidney and ureter expansion is not a differential diagnostic criterion of organic or functional urodynamic obstructions. However, using a principle of estimation of upper and lower urinary tracts condition, it is possible to make a prenatal differential diagnosis of variants of defects

For the purpose of revealing pre-natal urine dynamics preconditions ofdevelopment ofan infection ofurinary system atnewborns, feature urine dynamics functions of 101 fetus have been studied. Studying urine dynamics indicators of upper and lower urinary tracts of a fetus was carried out with the help of pre-natal ultrasonic cystometry process of filling and clearing the urinary bladder. It is established, that preconditions to development of urinary system infection in newborns are changes of urinary bladder capacity, frequency and speed of urination pre-natal developments.
