  • Priapism is defined as erection lasting for > 4 hours.
  • Low-flow priapism may be due to any of the following:
  • An excessive release of neurotransmitters
  • Blockage of draining venules (eg, mechanical interference in sickle cell crisis, leukemia, or excessive use of intravenous parenteral lipids)
  • Paralysis of the intrinsic detumescence mechanism
  • Prolonged relaxation of the intracavernous smooth muscles (most often caused by the use of exogenous smooth-muscle relaxants such as injectable intra-cavernosal prostaglandin E I)
  • Prolonged low-flow priapism leads to a painful ischemic state, which can cause fibrosis of the corporeal smooth muscle and cavernosal artery thrombosis. The degree of ischemia is a function of the number of emissary veins involved and the duration of occlusion
