Cavernosal Blood Gas Analysis

This is the gold standard test for distinguishing between ischemic and nonischemic priapism. A small needle is used to draw blood from the penis. In ischemic priapism, the blood is dark and lacks oxygen. In nonischemic priapism, the blood is bright red and well-oxygenated.

Doppler Ultrasonography

This non-invasive test uses sound waves to visualize blood flow in the penis. It can help differentiate between ischemic and nonischemic priapism. In ischemic priapism, there's little to no blood flow, while in nonischemic priapism, blood flow is normal or increased.
Priapism is a prolonged and often painful erection not related to sexual stimulation. Accurate diagnosis is crucial for treatment, involving tests like Cavernosal Blood Gas Analysis and Doppler Ultrasonography.

Additional Blood Tests

Doctors may order a complete blood count to check for blood disorders like sickle cell disease or leukemia. They might also test for drugs that can cause priapism. These tests help identify underlying causes and guide treatment.

FAQs

Is the blood gas test painful?

It may cause brief discomfort.

How long does Doppler ultrasound take?

Usually 15-30 minutes.

Are these tests always necessary?

Not always, but they're often crucial for proper diagnosis.

Key Takeaways

Accurate diagnosis through these tests is essential for effective priapism treatment and preventing complications.
