Penile Duplex Ultrasound

An imbalance of the penile arterial blood inflow and venous blood outflow, and nerve dysfunctions are the main causes of erectile dysfunction in more than 75% of men. Penile ultrasound and duplex doppler, enables characterization of arterial and venous blood flow with in the erect penis. It also allows for a detailed survey of the corpora cavernosa to identify calcification or scarring inside the erectile tissue of the penis.

The test involves an injection into the base of the penis at the start. During this injection, the substance that opens up the arteries, bringing blood into the erection chambers, is introduced into one of the erection chambers. Then the ultrasound unit is used to see inside the penis to look at the arteries and veins, and measure the blood flow in and out of the penis.
