Which action is typically taken to diagnose the type of priapism?

The typical action taken to diagnose the type of priapism is needle aspiration. This procedure involves inserting a needle into the corpus cavernosum of the penis to withdraw blood. The characteristics of the aspirated blood can help differentiate between the two primary types of priapism: ischemic (low-flow) and non-ischemic (high-flow).

In ischemic priapism, the blood is dark, indicating stagnant venous blood that has become deoxygenated, while in non-ischemic priapism, the blood is brighter and oxygenated, suggesting a different etiology such as a vascular issue. This distinction is crucial because treatment approaches differ significantly based on the type of priapism; ischemic priapism typically requires urgent intervention to prevent tissue damage and potential sexual dysfunction, whereas non-ischemic priapism may resolve spontaneously or require more conservative measures.

Other options may involve procedures or assessments typically not aimed directly at diagnosing priapism. Blood transfusions and endoscopic examinations are not standard diagnostic tools for this condition. Ultrasound imaging may provide some ancillary information, especially regarding blood flow characteristics, but it is not the definitive first line diagnostic procedure for identifying the type of priapism as needle aspiration is. Thus, needle
