BCEN CEN Practice Question

Which statement best describes high-flow (nonischemic) priapism encountered in the emergency department?

  • Emergency treatment requires immediate intracavernosal aspiration and phenylephrine injection to prevent ischemic necrosis.

  • It occurs primarily in patients with sickle cell disease and is caused by sludging of deoxygenated red cells in the corpora cavernosa.

  • It is the most common form of priapism, is extremely painful, and results from veno-occlusion with hypoxic blood trapped in the corpora.

  • It usually follows blunt perineal or penile trauma that creates an arteriocavernosal fistula, produces a prolonged but often painless partial erection, and is less common than low-flow priapism.
