Diagnosing Priapism: Key Tests and Procedures
Published: Oct 26, 2023
Accurately diagnosing priapism is crucial for proper treatment. Various tests and procedures help doctors determine the type and severity of priapism.
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.
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.
