Patient's question:
I recently don't know what's going on, my lower body is very uncomfortable, and I'm not getting morning erections anymore. What tests should be done for abnormal penile erection?Doctor's answer:
1. Complete blood count. There are significant changes in peripheral blood smear in patients with leukemia and sickle cell anemia.2. Local blood gas analysis of the cavernous sinus. It can differentiate high-flow and low-flow types. The former has blood gas analysis values similar to arterial blood, while the latter is similar to venous blood. It is noteworthy that early penile priapism is always of the high-flow type. There are two manifestations: one is local blood pH being slightly acidic, with significantly reduced partial pressure of oxygen and significantly increased partial pressure of carbon dioxide; the other is local blood pH being slightly alkaline, with no significant change in partial pressure of oxygen and no high partial pressure of carbon dioxide.
3. Cavernosography can also differentiate the two types.
