Ischemic: Removal of blood from the corpus cavernosum with a needle[3] Non-ischemic: Cold packs and compression[3]
Frequency
1 in 60,000 males per year[3]
Priapism is a condition in which a penis remains erect for hours in the absence of stimulation or after stimulation has ended.[3] There are three types: ischemic (low-flow), nonischemic (high-flow), and recurrent ischemic (intermittent).[3] Most cases are ischemic.[3] Ischemic priapism is generally painful while nonischemic priapism is not.[3] In ischemic priapism, most of the penis is hard; however, the glans penis is not.[3] In nonischemic priapism, the entire penis is only somewhat hard.[3] Very rarely, clitoral priapism occurs in women.[4]
Sickle cell disease is the most common cause of ischemic priapism.[3] Other causes include medications such as antipsychotics, SSRIs, blood thinners and prostaglandin E1, as well as drugs such as cocaine.[3][5] Ischemic priapism occurs when blood does not adequately drain from the penis.[3] Nonischemic priapism is typically due to a connection forming between an artery and the corpus cavernosum or disruption of the parasympathetic nervous system resulting in increased arterial flow.[3] Nonischemic priapism may occur following trauma to the penis or a spinal cord injury.[3] Diagnosis may be supported by blood gas analysis of blood aspirated from the penis or an ultrasound.[3]
Treatment depends on the type.[3] Ischemic priapism is typically treated with a nerve block of the penis followed by aspiration of blood from the corpora cavernosa.[3] If this is not sufficient, the corpus cavernosum may be irrigated with cold, normal saline or injected with phenylephrine.[3] Nonischemic priapism is often treated with cold packs and compression.[3] Surgery may be done if usual measures are not effective.[3] In ischemic priapism, the risk of permanent scarring of the penis begins to increase after four hours and definitely occurs after 48 hours.[3][6] Priapism occurs in about 1 in 20,000 to 1 in 100,000 males per year.[3]
