Ultrasound

Varicocele can be reliably diagnosed with ultrasound, which will show dilatation of the vessels of the pampiniform plexus to greater than 2 mm. The patient being studied should undergo a provocative maneuver, such as a Valsalva maneuver (straining, like he is trying to have a bowel movement) or standing up during the exam, both of which are designed to increase intra-abdominal venous pressure and increase the dilatation of the veins. Doppler ultrasound is a technique of measuring the speed at which blood is flowing in a vessel. An ultrasound machine that has a Doppler mode can see blood reverse direction in a varicocele with a Valsalva, increasing the sensitivity of the examination.
