Persistent Erection
Nonischemic priapism
Less commonly, priapism is due to uncontrolled flow of blood into the penis. Such abnormal blood flow usually results from an injury to an artery in the groin area. Nonischemic priapism is also known as high-flow priapism. It is less painful than ischemic priapism and does not lead to tissue death. The penis is erect but not fully rigid. Subsequent erectile dysfunction is much less common than in ischemic priapism.
