The aim of the investigation was to study the quantitative morphometric characteristics of the lymphoid follicles in the walls of the urinary tract using the method of macro-microscopy.Material and methods. The topography, number and size of lymphoid nodules in the walls of the ureters, bladder and urethra obtained from the corpses of 142 people of different ages were studied by macro-microscopy using a binocular stereomicroscope MBS-9 after elective staining with Harris's hematoxylin. The material was taken from persons whose death was due to injuries and asphyxia, and autopsy showed no signs of pathology of the urinary organs. For statistical data processing, parametric statistics methods based on the Statistica 6.0 program were used. Statistical data processing included the calculation of arithmetic mean indicators, their errors, analysis of the amplitude of the variation series of each indicator.Results. Lymphoid nodules are permanent structures in the walls of the ureters, bladder, and urethra. The number of lymphoid structures is maximum in the 1st period of childhood. In subsequent age periods, regardless of organ affiliation, the number of lymphoid nodules decreases with age, reaching a minimum in old age. In the 1st period of childhood, the maximum values are also reached by the size indicators of lymphoid nodules, increasing in the walls of the right ureter by 5.06 times, the left ureter – by 5.22 times, the bladder – by 4.60 times, the male urethra – by 4.60 times, female urethra – 4.65 times compared with the neonatal period (p |
