Penile Doppler Assessment

Clinical information

A 27-year old man presented with problems maintaining erections. A Doppler ultrasound of the penis was requested to provide an insight to the situation while assessing the penile blood vessels for a vasculogenic aetiology.

Case Description

Ultrasound was performed using a high frequency linear transducer of up to 16 MHz after administering 20 mcg of Caverject IM. The assessment was carried out every 5 minutes post injection.

The corporal bodies were initially examined in B-mode to assess for any (Peyronie’s) plaques. Afterwhich, the right and left cavernosal arteries were interrogated using colour and spectral Doppler ultrasound to evaluate the flow velocities.

Both peak systolic and end diastolic velocity parameters are the most useful in determining arterial or venous insufficiency causes of erectile dysfunction.
