(A) Priapism is defined as a penile erection lasting longer than 4 h, unrelated to sexual stimulation, and persistent even after ejaculation/orgasm. It is sub-divided into two major types: ischemic (synonymous with low flow or venocclusive) priapism, which is a medical emergency that requires immediate attention and non-ischemic (synonymous with high flow or arterial) priapism, which is not an emergency. Ischemic priapism results from failure of the venocclusive mechanism to open during erection.
