[Color Doppler sonography of normal male genitalia and varicocele]

The present paper reports on the results of complex sonographic examination of scrotum organs in 116 patients. The study was performed with Siemens sonographic unit. According to clinico-laboratory data and results of operative intervention, the patients were divided into two groups. The 1st group (8 persons) had no pathology in the scrotum organs, the 2nd group (98 patients) had diagnosis of varicocele. In norm capsular, centripetal and transmeridian arteries were visualized in the projection of testis in colour Doppler sonography. Resistancy index was measured. The group with varicocele in colour Doppler sonography with Valsalva test showed a prolonged retrograde wave of blood flow during the whole period of tension. To determine the stage of pathologic process, a scale system had been used. Doppler sonography enables to reveal various types of reflux. The character of reflux determines a pathogenetic cause of varicocele that effects on the choice of the method of operative intervention. Parameters of colour Doppler sonography allow to determine the stage of the disease and reveal subclinical varicocele in cases when pampiniform plexus is absent, but significant hemodynamic changes take place. The data of Doppler sonography have been confirmed by the results of operative intervention.
