[Correlative relationships between the microangioarchitectonics and histomechanics of the human urinary bladder].

The intraorganic blood bed in the human urinary bladder walls is a multilayer vascular plexus with a morphofunctional specificity of microcirculatory construction in every layer. In the formation of architectonic features and structure of the microcirculatory parts of the urinary bladder wall, is phase activity (alternate filling and emptying) plays an important role. A suggestion is made that large arterial and venous plexus with peculiar constraction presenting in the most important urodynamic sections (in the ureteral orifice and in the ureteral segment of the urinary bladder) perform not only trophic function, but also actively participate in urodynamics of these parts.
