A penile ultrasound is performed by a radiologist or angiologist using the Doppler imaging technique which allows for precise mapping of the vascular structures of the penis. This imaging technique is a crucial element in the diagnostic process of erectile dysfunction of vascular origin. The physician performes an examination to determine the patient’s individual anatomy, assess the state of the vascular structures of the penis and to exclude potential anatomical flaws or vascular pathologies (i.e. vascular leak syndrome). Furthermore, during a penile ultrasound vessels responsible for transporting the blood to and from the penis and blood flow velocities within them are examined. The examination also allows for indirect assessment of the smooth muscle tissue and endothelial function
During penile ultrasound, patients remains in lying position. The procedure consists of 2 stages: first during a state of rest and second during a pharmacologically induced erection. In early stages of the penile ultrasound, doctor injects carvenous bodies with a substance dilating blood vessels. After the injection, blood supply to the penis increases significantly, what causes an erection after approximately 15 to 25 minutes. Diagnostics begins after few minutes pass since the injection causing erectionDoctor locates carvenous bodies and blood vessels using ultrasonic probe, what allows for examination of course of deep arteries in carvenous bodies and measures blood flow speed in their lights. In most cases of pharmacologically induced erection, it does not cause discomfort and terminates after around 45 minutes.
Penile ultrasound allows for differentiation of types of erectile dysfunctions caused by vascular disorders. Key elements of this diagnositcs are coefficients of peak systolic velocity (PSV) and end diastolic velocity (EDV). Correct value of PSV should be larger than 30 cm/s; smaller values suggest presence of patalogy, most often resulting from atherosclerotic or fibrous lesions. In case of too high EDV value (larger than 7 cm/s), there is a high possibility of patology related to excessive blood outflow throughout vein system. Incorrect EDV values are most often observed due to presence of arteriovenous fistula, vein leakage or fibrosis of tunica albuginea.
