|Non-ischemic (high-flow)||Ischemic (low-flow)|
|Physical Exam||Typically painless, not fully tumescent||Painful, fully tumescent with corpus cavernosa rigidity without involvement of corpus spongiosum and glans penis|
|Aetiology||High-flow priapism is extremely rare and most commonly associated with antecedent trauma including blunt trauma, or resulting from needle injury of the cavernosal artery.||Low-flow priapism is caused by impaired relaxation and/or paralysis of cavernosal smooth muscle and in sickle-cell disease|
