Penile ultrasound with Doppler

What is a Doppler ultrasound of the penis?

An ultrasound is an imaging technique that uses ultrasound to visualize internal organs, allowing doctors to examine them more precisely.

The penile ultrasound allows visualizing the cavernous body and the spongy body.

It can then be used to diagnose and monitor the course of several diseases that affect the penis, including erectile dysfunction (ED), plaques (such as those caused by Peyronie’s disease), fibrosis, tumors and even cancer.

Men who have erection problems usually have to have a Doppler ultrasound. This examination makes it possible to visualize the blood circulation of the cavernous bodies.

The quality of human erections depends on the blood circulation. When a man is sexually stimulated, the arteries of his penis dilate so that blood can flow into it. This blood allows the penis to stiffen so that the man can have sex. The veins of the penis contract to retain blood. When the man is no longer stimulated or when he ejaculates, the veins dilate again so that the blood can circulate again inside his body.

Many men who suffer from erectile dysfunction have problems with blood circulation. It is possible that their arteries do not dilate enough to allow the flush into their penis, or that their veins do not contract enough to retain the blood inside their penis. Both of these problems can affect the quality of erections.

How is an penile ultrasound performed with an injection?

Examination of the penile Doppler begins with a drug injection, which causes an erection by dilating the arteries and increasing the blood flow. Thereafter, Dr Marois moves a small ultrasound probe with a gel along the skin of the penis. This sensor sends data to a computer to allow the doctor to check how fast the blood is flowing in and out of the penis.

A Doppler ultrasound is a non-invasive and generally painless examination. Some men experience pain or bruising at the point of injection. Some men may also experience dizziness for several minutes. If the erection caused by the injection lasts too long, the doctor may inject another medicine to contain it.

How to prepare for an penile ultrasound with Doppler?

Men are generally asked to avoid taking erectile dysfunction medications (such as Viagra, Levitra or Cialis) during the two days before the test. They may also be asked not to have sex or to masturbate on the day of the exam.

What is the utility of penile ultrasound and Doppler in erectile dysfunction?

Echo-Doppler examination is an integral part of assessing erectile dysfunction. It is not enough to diagnose arterial damage, whose frequency is estimated at 40% of erectile dysfunction commonly examined, but it is necessary to determine its severity.

Also, intravenous injection therapy can be done at the same time when erectile dysfunction no longer responds to medical treatment such as Viagra or Cialis.

What is the utility of penile ultrasound and Doppler in Lapeyronie's disease?

It allows to visualize the cavernous plate in order to evaluate it well. Also, the curvature in erection is measured after the Caverject injection.
