Priapism. From Priapus to the present time.
Advances in the pharmacotherapeutic options available to treat erectile dysfunction over the past decade have transformed the field of impotence. The initial foray into this field with intracavernous injections of papaverine rapidly expanded the number of men seeking attention for priapism, a previously rare clinical condition. The recent widespread use and acceptance of oral agents for the treatment of erectile dysfunction, with a reduced incidence of priapism has decreased the number of men at risk for injection-related prolonged erections. The use of recreational drugs (cocaine) and perineal trauma leading to presentations of priapism seem to be rising in incidence. The urologist remains the consultant-specialist ultimately responsible for these men and should be cognizant of the array of treatments described for this condition. Early determination of the state of corporal oxygenation is essential and will define the optimal management approach. A wide range of medical conditions and risk factors may be etiologic and should be elicited from the patient at the initial interview. Low-flow ischemic priapism requires a rapid resolution, often achieved through use of alpha-agonists orally or by direct injection into the penile circulation, whereas nonischemic priapism can be treated more conservatively. Research into this condition has only recently been initiated. Through greater understanding of the pathophysiology of priapism, the clinician may become armed with etiology-specific medical alternatives providing timely detumescence for men with prolonged erections.
