● Prolongation of penile erection without sexual stimuli for more than 4 hours
● Either low flow / ischemic (disorder of venous outflow or stasis) or high flow / nonischemic (disorder of arterial flow, may be due to anatomic abnormality or perineal trauma with resulting fistula, Can Urol Assoc J 2009;3:60)
● Usually due to vascular diseases (sickle cell disease, leukemia, thalassemia, Fabry’s disease) or neurological disorders (spinal cord lesions/trauma) or medications (treatment for erectile dysfunction, antihypertensives, antipsychotics, antidepressants, blood thinners)
● Metastatic carcinoma to the penis may present with “malignant” priapism in up to 40% of cases
● Frequently associated with pain
● May have fever and difficulty voiding
● Associated with erectile dysfunction in 17% to 50%
● Potential complications include ischemia, thrombosis and permanent impaired erectile dysfunction
● Low flow / ischemic priapism: prompt intervention is required; corpora cavernosal aspiration/irrigation with concomitant usage of a sympathomimetic agent; may also need systemic therapy if an underlying systemic disorder; surgical intervention may be necessary if medication fails (Rev Urol 2010;12:56)
● High flow / nonischemic priapism: not a surgical emergency; resolves spontaneously in 60%, particularly if no underlying anatomic abnormality; selective arterial embolization if it persists
