[Hemodynamic studies on varicocele using bidirectional ultrasound Doppler sonography].
At first the ultrasonic Doppler sonography is described in the evaluation of the retrograde venous blood flow in a varicocele. With the Doppler stethoscope the incidence of venous reflux amounted to 70% in young men aged from 19 to 22 years. At physical examination a palpable varicocele was detected in 55% of the cases. By the bidirectional technique you can define various haemodynamic types of varicoceles: "pressure-type" and "shunt-type". 205 patients with varicoceles were examined by bidirectional Doppler probe. The Doppler recording was correlated with the severity of varicocele. In small varicoceles the "pressure-type" is found most frequently, while in large varicoceles the "shunt-type" occurs.
