After the physical exam is complete, the doctor will take a blood gas measurement of the blood from the penis. Ischemic or "low-flow" priapism occurs when blood disorders (such as sickle cell anemia or leukemia), prescription medication, or substance use cause the veins in the penis to constrict and keep blood from exiting the erection chambers (corpora cavernosa). However, the longer medical attention is delayed, the greater the risk of permanent erectile dysfunction.

In contrast, nonischemic (high flow) priapism results from a trauma- related arterial injury. Blood gases on blood aspirated from the corpora cavernosa revealed the presence of "high-flow" priapism. The onset is usually delayed after injury, but typically it is clinically evident within 72 hours.9 Aspiration of the cavernosa reveals arterial blood. Acute onset of severe pain, rigidity, and other compartment syndrome clinical findings are noted. 2022 Jul;10(5):852-862. doi: 10.1111/andr.13175. American Urological Association (AUA) guidelines.

The determination of erectile function at a mean follow-up of 41 months (range 17 to 64) was performed using the International Index of Erectile Function.

The site is secure. Because there isn't a risk of damage to the penis, your doctor might suggest a watch-and-wait approach. Thus, the penis has three pairs of arteries: two urethral arteries that run on either side of the penile urethra in the corpus spongiosum, two cavernosal arteries, each running on the center of the corpus cavernosum, and two dorsal arteries of the penis running on either side of the dorsum of the penis between the tunica albuginea and Buck fascia, near the dorsal nerves of the penis.26. MeSH If you have an erection lasting more than four hours, you need emergency care. This treatment might be repeated until the erection ends. Causes of high-flow priapism include: blunt trauma to the perineum or penis, with laceration of the cavernous artery, which can generate an arterial-lacunar fistula.
