Penile Doppler Ultrasound

During the procedure, an injection will be given to open the arteries and allow for an erection. This may cause a burning sensation, and you may experience mild discomfort during the injection. We will then use an ultrasound probe along the shaft of your penis to measure blood flow in the penile arteries on both sides. There is no pain during the ultrasound portion of the study.

This procedure is performed while you are lying on your back on an examination table. It allows your urologist to assess your response to medication as the procedure is done with an erect penis.

After the procedure, the erection should go away within four hours. However, occasionally, some patients may experience a prolonged erection, which is a medical emergency. If this occurs, please call the office, or go to your nearest emergency department or urgent care center for treatment.
