93980 Duplex scan of arterial inflow and venous outflow of penile vessels; complete study

Name of the Procedure:

Duplex Scan of Arterial Inflow and Venous Outflow of Penile Vessels; Complete Study

Summary

This procedure uses ultrasound technology to evaluate blood flow in the arteries and veins of the penis. It helps diagnose problems with blood flow that could be causing erectile dysfunction.

Purpose

The primary purpose is to diagnose issues with blood circulation in the penile vessels, which can contribute to erectile dysfunction. The goal is to identify any blockages or abnormalities in blood flow.

Indications

• Erectile Dysfunction (ED)
• Suspected vascular abnormalities
• Pre-surgical assessment for penile implants

Preparation

• Minimal preparation is required.
• Patients may be asked to avoid smoking and caffeine prior to the procedure.
• Ensure a full bladder by drinking water beforehand, if instructed by the healthcare provider.

Procedure Description

1. The patient will lie flat on an examination table.
2. A special gel is applied to the penis and surrounding areas.
3. A transducer (ultrasound probe) is moved over the skin to capture images of the blood vessels.
4. Sometimes, an injection (vasodilator) may be given to induce an erection and better visualize blood flow.
5. Images and blood flow measurements are obtained both when the penis is flaccid and erect.

Duration

The procedure typically takes around 30 to 60 minutes.

Setting

The duplex scan is performed in an outpatient setting, such as a hospital's radiology department or a specialized clinic.

Personnel

• Radiologist or specialized ultrasound technician
• Urologist (in some cases)

Risks and Complications

• Mild discomfort or bruising at the injection site (if a vasodilator is used)
• Temporary swelling
• Very rare risk of priapism (prolonged erection)

Benefits

The primary benefit is the accurate diagnosis of vascular-related erectile dysfunction, which can guide appropriate treatment. Results are typically available shortly after the procedure.

Recovery

• No significant recovery time is needed.
• Patients can return to normal activities immediately.
• Follow-up with the referring physician to discuss results and next steps is recommended.

Alternatives

• Pharmacological testing (medications to assess ED)
• Penile angiography (more invasive, uses dye and X-rays)
• MRI or CT scan (less commonly used but provides detailed images)

Patient Experience

Generally, the procedure is well-tolerated. Patients might feel cold from the gel and a mild pressure from the transducer. If an injection is given, there might be a brief sting. Any discomfort is usually minor and short-lived.
