COLOR
DOPPLER OF VARICOCELE
Varicocele is the most common correctable
cause of male infertility. Ultrasonography and color Doppler play an important
role in the diagnosis, particularly in subclinical cases (10%). The veins of
the pampiniform plexus are dilated to exceed 2 mm in diameter. The veins are
characterized by retrograde flow in the internal spermatic vein. The
examination performed in standing posture and during valsalva the veins often
dilate to 3 mm and more (figs 14.16 to 14.17B)
