Alternative Pathways in the Pathophysiology of Priapism

17519

Priapism is described as the extended unpreferred erection status without any sexual stimulus. There are three types of priapism which are classified as ischemic, non ischemic and recurrent priapism depending on the blood flow of the penile artery. Ischemic priapism is a real urological emergency which requires urgent and appropriate approach. Recently, it was shown in experimental priapism models that adenosine and hemoxygenase-1-carbonmonoxide (HO1-CO) are effective in the development of recurrent priapism attacks. Moreover, it was reported that dysregulated PDE-5 acti-vity, decreased Norepinephrine response and altered Endothelin receptor activity may be effective in the pathophysiology of priapism. In the present study, the experimental data related to the pathways that play an active role in the pathophysiology of priapism and its reflections on the practice were evaluated.
