[Differentiation of various types of varicocele based on their hemodynamic aspects using the ultrasonic Doppler technic].

With the help of bidirectional ultrasonic Doppler technique the inflow as well as the outflow of the venous blood (v. testicularis, v. ductus deferentis, v. cremasterica) in the patients suffering from varicocele can be studied. On the basis of the results two types of varicocele disorders can be identified: a) "Shunt-type" in which cases the inflow is equal to the outflow, b) "pressure-type", in which the outflow is relatively decreased.
