[Comparative hemodynamic evaluations of varicocele by bidirectional ultrasonic Doppler sonography and phlebography of the internal spermatic vein].

Clinical studies (degree of severity) and bidirectional ultrasonic Doppler sonography (Pressure-type, Shunt-type) of varicocele were compared with the phlebography of the internal spermatic vein (degree of spermatic incompetence, diameter of the int. spermatic v.). Doppler probe and phlebography are equivalent methods to demonstrate the venous reflux in palpable varicocele and for follow-up examination after sclerotherapy. The subclinical varicocele is discussed. The slight degree of spermatic incompetence (reflux by Valsalva's manoeuvre) is responsible for the small varicocele (grade I) and the Pressure-type. The severe degree of spermatic incompetence (spontaneous reflux) causes the Shunt-type and the large varicocele (grade III) as well as a dilatation of the internal spermatic vein.
