MORPHOMETRIC PARAMETERS AND TOPOGRAPHY OF THE HUMAN PROSTATE GLAND OF THE FIRST MATURE PERIOD ACCORDING TO MAGNETIC RESONANCE IMAGING
 Magnetic resonance tomograms of the pelvic organs of patients aged 21 to 35 years (n = 40) without complaints from the urinary system and without volumetric processes in the pelvic cavity were studied and interpreted to determine the in vivo topographic and anatomical characteristics of the prostate gland and comparison of the obtained data with the existing ones. The following parameters were evaluated: the linear dimensions of the prostate gland (sagittal, frontal, vertical), the volume of the prostate gland, the distance from the gland to the pubic symphysis, to the plane of the entrance to the pelvis, the distance to the sacrum, to the pelvic ring right and left, the length and the square of the contact surface of the prostatic gland to urine bladder, to the rectum and to the seminal vesicles, the distance from the anus to the lowest point of the gland's contacts to the rectum. For all measurements, the mean, the error of the mean, the minimum, the maximum values, and the standard deviation of the observation were calculated. The prostate gland is located below the plane of entry into the pelvis, occupies the middle position in it, the average volume of the prostate gland at the studied stage of ontogenesis is 23.1 ± 0.8 cm3 with a minimum value of 14.6 cm3 and maximum - 33.0 cm3 with an overwhelming prevalence patients with mean values (22 patients from the sample). There is significant variability of the skeleto-topic and syn-topic parameters of the prostate gland.
