Aim of investigation is assessment of a vesicoprostatic plexus and penis venous hemodynamics role in initiation of erection and the erectile dysfunction genesis.
Materials and Methods. 33 humans at the age of 46—61 years with a normal erection are examined. A state of the penis and prostatic plexus veins at rest and in a phase of erection is studied with a method of spongiography.
Results. A roentgenologic picture of the penis and vesicoprostatic plexus venous bed is received. A dynamics of the venous bed alterations at initiation of erection in practically all the healthy patients is fixed, which has permitted to take such alterations for a norm.
Conclusion. A venous outflow from a penis venous system through a vesicoprostatic plexus is significantly altered at erection. An active contraction of a venous wall favors a venous blood pumping along the penis vein system, devoid of the venous valves, to the cavernous bodies, which leads to a penis tumescence.
