Sickle cell disease is the most common cause of ischemic priapism. Ischemic priapism is typically treated with a nerve block of the penis followed by aspiration of blood from the corpora cavernosa.

Some sources give a duration of four hours as a definition of priapism, but others give six: “The duration of a normal erection before it is classifiable as priapism is still controversial. Ongoing penile erections for more than 6 hours can be classified as priapism. Because ischemic priapism causes the blood to remain in the penis for unusually long periods of time, the blood becomes deprived of oxygen and can cause damage to the penile tissue itself. Should the penile tissue become damaged, it can result in erectile dysfunction or disfigurement of the penis. Priapism may also be associated with glucose-6-phosphate dehydrogenase deficiency, which leads to decreased NADPH levels. NADPH is a co-factor involved in the formation of nitric oxide, which may result in priapism. Sickle cell disease often presents special treatment obstacles. Hyperbaric oxygen therapy has also been used with success in some patients. Priapism is also found to occur in extreme cases of rabies.

Priapism also occurs due to encephalitic rabies. Priapism can also be caused by reactions to medications. The mechanisms are poorly understood but involve complex neurological and vascular factors. The diagnosis is often based on the history of the condition and the physical exam. Blood gas testing the blood from the cavernosa of the penis can help in the diagnosis. If the low flow type of priapism is present the blood typically has a low pH while if the high flow type is present the pH is typically normal. Medical evaluation is recommended for erections that last for longer than four hours. Pain can often be reduced with a dorsal penile nerve block or penile ring block. For those with ischemic priapism the initial treatment is typically aspiration of blood from the corpus cavernosum.

This is done on either side. If aspiration is not sufficient a small dose of phenylephrine may be injected into the corpus cavernosum. This causes the blood to leave the penis and return to the circulation. This procedure can be performed by a urologist at the bedside. Proximal shunts, such as the Quackel’s, are more involved and entail operative dissection in the perineum to where the corpora meet the spongiosum, making an incision in both, and suturing both openings together. As the complication rates with prolonged priapism are high, early penile prosthesis implantation may be considered.
