Abstract
Priapism is defined as a persistent penile erection (typically 4 h or longer) that is unrelated to sexual stimulation. Priapism can be classified as either ischemic or nonischemic. Ischemic priapism, the most common subtype, is typically accompanied by pain and is associated with a substantial risk of subsequent erectile dysfunction. Prompt medical attention is indicated in cases of ischemic priapism. The initial management of choice is corporal aspiration with injection of sympathomimetic agents. If medical management fails, a cavernosal shunt procedure is indicated. Stuttering (recurrent) ischemic priapism is a challenging and poorly understood condition; new management strategies currently under investigation may improve our ability to care for men with this condition. Nonischemic priapism occurs more rarely than ischemic priapism, and is most often the result of trauma. This subtype of priapism, which is generally not painful, is usually initially managed with conservative treatment.
Key Points
-
Ischemic priapism is a medical emergency; prompt diagnosis and immediate, direct treatment are required
-
Injection of sympathomimetic agents is the first-line treatment of choice for ischemic priapism
-
If sympathomimetics fail, surgical shunt should be used to treat ischemic priapism
-
Androgen ablation is commonly used to treat recurrent, stuttering priapism, although PDE5 inhibitors might provide a novel means of managing this condition
-
Management of priapism in children is generally similar to its management in adults, although hormonal modulation is deemed unsuitable for use in prepubertal or pubertal boys
-
Conservative management might be adequate for nonischemic priapism
