Penile Ultrasound in Houston, TX

What is a Penile Ultrasound?


A duplex ultrasound is a test performed in the clinic that evaluates how the blood is moving in and out of the penis. It utilizes sound waves that bounce off blood vessels to create images. In order to fully evaluate your condition, an initial scan is obtained to measure the size of the arteries (blood vessels that bring the blood into the penis) and verify presence of plaques or scar tissue.

Dr. Jonathan Clavell is a fellowship trained urologist and men’s health specialist in Houston, TX. Dr. Clavell uses penile ultrasounds to diagnose certain conditions. Learn more and schedule your appointment with Dr. Clavell today.


What Can I Expect During the Procedure?


The procedure will involve the use of an injection of a drug combination of three potent vasodilators (medications that will expand the blood vessels and bring blood into the penis). The drug combination is composed of Papaverine, Phentolamine and Prostaglandin E-1. These are administered directly into the penis, via a single injection, which eventually should cause an erection. It is expected that patients with diseased blood vessels (such as those in patients with diabetes, smoking, or heart disease) will not develop a full erection.

A final scan of the penis is performed with the ultrasound probe and a pulsed Doppler is utilized to look at the increase in blood flow.  


What is the Purpose of Doing This Study?


The penile ultrasound provides an objective assessment of how the penis is working. The ultrasound will help reveal the presence of scar tissue inside penis. We will also attempt to evaluate if there is inadequate blood going in (arterial insufficiency) or if the blood is unable to stay trapped inside the penis (venous leakage). Dr. Clavell will then discuss the results with you and explain what will be your best treatment option.


Are There Any Side Effects?


Given that the test involves a penile injection that is intended to produce an erection, it is important that you be aware of the timing of your erection. An erection lasting more than 4 hours is called priapism and is considered an emergency, which should be addressed immediately.  Our office is equipped to treat this condition to avoid any complications.
