[Priapism: diagnosis and treatment].

Priapism, prolonged and painful erection, is an exceptional cause of consultation in the pediatric population. High- and low-flow priapism and recurrent prolonged erection must be differentiated, as the prognosis and treatment of these entities differ. Assessment of patients with priapism begins with a detailed history, physical examination, and complete blood cell count. The definitive diagnosis is given by penile Doppler ultrasonography, corpora cavernosa blood gas analysis, and pelvic arteriography. We present two patients who attended our emergency service in the last year and propose an algorithm for the diagnosis and treatment of this entity.
