Final Answer:
The initial treatment for Ischemic Priapism involves aspiration of blood from the corpora cavernosa, followed by phenylephrine injection, and if needed, shunt surgery.
Step-by-step explanation:
Ischemic Priapism is a urologic emergency characterized by prolonged and painful penile erection. The recommended sequence of treatments involves a step-by-step approach. The first step is the aspiration of blood from the corpora cavernosa, aiming to relieve the engorgement causing ischemia. This procedure may be followed by the injection of phenylephrine, an alpha-1 adrenergic agonist, directly into the corpora cavernosa. Phenylephrine helps constrict blood vessels and restore normal blood flow, alleviating priapism. If these measures are unsuccessful, or if the priapism recurs, shunt surgery may be considered to create a pathway for blood to bypass the blocked areas and reduce the risk of future episodes.
The order of these treatments is crucial for effectively managing Ischemic Priapism and preventing potential complications, including erectile dysfunction.
