Penile doppler is a diagnostic test used in the evaluation of erectile dysfunction by using ultrasound to measure blood flow to the penis.
- Erectile dysfunction (ED)
- Treatment failure with ED medications
In a procedure room, the patient lies on an exam table, and the penis is injected with a medication that causes an erection. The blood flow to the penis at the time of erection is then measured with an ultrasound device to determine the degree of vascular abnormality causing ED. The entire procedure takes about thirty minutes to complete.
- Helps to guide future therapy for ED
Most patients will have some minimal discomfort at the site of the injection. On rare occasions, a patient may have a sustained erection that will require further treatment to resolve.
