[Functional evaluation of reduction of venous outflow from the testis in left-side varicocele in children].

A functional state of venous return from the testicles was estimated on the grounds of a direct measurement of pressure gradients among main points of venous return on 61 unoperated adolescents, aged from 13 to 15, and with marked varicocele; and in 10 children of the same age without varicocele (a control group). The results of the estimation have proved that the hydrostatic pressure in the veins of the pampiniform plexus is directly responsible for their hyperdistension in the vertical position. An exceptional role of renal venous hypertension in the genesis of varicocele in children is doubtful.
