Abstract.
Objectives. To study age-related changes of intra- and extraorganic blood vessels of the prostate in males of mature and elderly ages.
Material and methods. Pelvic organocomplexes from 59 dead bodies of males of the first, the second periods of mature and elderly ages were studied with a complex of anatomical, histological, morphometric and statistical techniques.
Results. The internal diameters of the extraorganic vessels significantly (p <0,05) increase in all three age periods. The internal diameter of the intraorganic arteries increases in the elderly age (p<0,05), and the internal diameter of the intraorganic veins significantly increases with age in all studied groups. The thickness of the extraorganic arterial walls has the largest size at the elderly age, but that of the extraorganic arterial walls is a bit greater in the I period of the mature age than in the aa period.
The increase of the wall thickness of the extraorganic veins and the intraorganic arteries is observed only in the elderly age. In the II period of the mature age the thickness of walls of intraorganic veins increases in comparison with the e period and does not change in comparison with the elderly age.
The thickness of the middle tunic of the extraorganic arteries statistically significantly (p<0,05) increases only in the elderly age. The thickness of the middle tunic of the extraorganic veins does not change throughout all age periods. This index of intraorganic arteries and veins has the lowest value (p<0,05) in the first period of the mature age, but statistically does not change during the second period of the mature and elderly ages.
Conclusions. In the second period of the mature age in the blood vessels of the prostate in males changes characteristic of the improvement of the hemodynamic load with the beginning in the extraorganic veins are revealed. In the elderly age, the middle tunic of the intraorganic blood vessels increases in response to the continuing increase in the diameters of the extraorganic vessels.
Key words: prostate, arteries, veins, venous plexus, mature age, elderly age.
