Priapism is a serious and often painful urological condition. It is a medical emergency that requires immediate attention, as a delay in treatment can result in irreversible tissue damage and erectile dysfunction permanent.
Despite being a rarely discussed topic, understanding its causes, symptoms, and the urgency of taking action is crucial for male sexual health. In this article, you'll find all the necessary information about priapism, from its pathophysiological foundations to its clinical management, to raise awareness and educate about the criticality of this condition.

What is priapism?
Priapism is an erection that lasts for more than four hours without sexual stimulation. Unlike a normal erection, priapism represents a failure of the erection-deactivating mechanism.
In a healthy erection, the balance between arterial blood flow and venous drainage is precisely maintained. In priapism, this balance is disrupted, trapping blood within the corpora cavernosa. This prolonged accumulation of deoxygenated blood causes pain, inflammation, and, if unresolved, tissue death (fibrosis) and impotence.

Ischemic priapism
It accounts for more than 95% of cases. It is also known as veno-occlusive priapism. It occurs when blood becomes trapped in the corpora cavernosa, preventing normal drainage and leading to blood stasis. The blood becomes deoxygenated and acidified, creating a toxic environment for muscle tissue.
Blood flow is low or non-existent, the penis is completely rigid and very painful, and the blood is low in oxygen, which can give a cyanotic (blue/purple) appearance to the glans, which is usually soft in contrast to the rigid shaft.
It is strongly associated with hematological diseases, the use of medications to treat erectile dysfunction, and certain oral medications.
Non-ischemic priapism
It is much less common and less painful. Also called arterial priapism, it occurs due to a fistula or abnormal communication between an artery and the spaces of the corpora cavernosa, usually as a result of perineal trauma or direct trauma to the penis. This fistula allows a constant, unregulated arterial flow that maintains a partial erection.
Blood flow is high, the penis is erect but not completely rigid.
Intermittent priapism or stuttering
This is a recurrent pattern of priapism, typically of the ischemic type. It is characterized by repeated episodes of prolonged erections that resolve spontaneously but recur after varying periods of time. It is very common in patients with sickle cell anemia.
These episodes, although transient, are equally dangerous in the long term and can cause cumulative tissue damage and require a long-term management plan to prevent acute episodes.
Why does priapism occur?
Causes
They can be hematologic, such as sickle cell anemia, in which sickle-shaped red blood cells obstruct venous drainage from the penis. Other causes include leukemia and other blood dyscrasias.
Pharmacological causes can occur due to the use of medications for erectile dysfunction, antidepressants, antipsychotics, antihypertensives, anticoagulants, or recreational drugs, especially the use of synthetic cannabinoids.
An injury to the perineum, pelvis, or penis can cause nonischemic priapism by damaging an artery. Tumors in the pelvis or penis infiltrate or compress blood vessels or nerves.
Other causes may include spinal cord injuries, cauda equina syndrome, spinal anesthesia, infections such as malaria or mumps, although these are rare, and, in cases of amyloidosis or kidney dialysis, calcium metabolism failure.

Factors riesgo
Some risk factors include having sickle cell anemia or another blood disorder, receiving injections of erectile dysfunction medications, taking certain psychiatric or blood pressure medications, using recreational drugs or alcohol excessively, having suffered trauma to the pelvis, perineum, or penis, and having a history of cancer or metabolic diseases.
Symptom
In ischemic priapism they are the ePersistent (more than 4 hours) unwanted and unrelated retraction with arousal, intense and progressive pain in the penis and glans, extreme rigidity of the corpora cavernosa, while the glans usually remains soft, and the penis may appear bruised or bluish in color.
In non-ischemic priapism there is an eprolonged but not completely rigid erection, no or mild pain, erection may be intermittent, worsening at night and improving with physical activity, and the penis may have a throbbing sensation.
It may interest you: morning erections.
Complications of priapism
If left untreated, especially ischemic priapism, complications can be devastating. These include permanent erectile dysfunction due to the death of smooth muscle tissue and fibrosis. The fibrosed tissue loses its ability to relax, making it impossible to achieve an erection; fibrosis of the corpora cavernosa, which can cause deformity and curvature of the penis (Peyronie's disease) even in a flaccid state; infarction and gangrene; in extremely severe and prolonged cases (more than 24 to 48 hours), the tissue can become necrotic, even requiring a partial or total penectomy; and chronic pain and urination problems.
Diagnosis of priapism
Medical history and physical examination
The duration of the erection, level of pain, history of trauma, medications taken, history of similar episodes, and preexisting medical conditions are analyzed. Penile palpation may also be performed.
Cavernous blood gasometry
It is the diagnostic test par excellence. A small blood sample is extracted from the corpora cavernosa with a fine needle, which can confirm ischemia.
Imaging studies and other tests
Penile Doppler ultrasound assesses blood flow. In ischemic priapism, venous flow is absent and arterial flow is minimal. In non-ischemic priapism, the arterial fistula and high blood flow can be visualized.
And blood tests can be used to look for underlying causes such as sickle cell anemia, leukemia, or metabolic disorders.
Treatment of priapism
Ischemic priapism
It's an emergency treatment designed to decompress the corpora cavernosa and evacuate deoxygenated blood to restore normal blood flow. Performed under local anesthesia, blood is aspirated from the corpora cavernosa, which can resolve 30% of cases.
Sterile saline is then irrigated to flush out the acidified blood, a vasoconstrictor medication is injected directly into the penis, and if the condition persists for more than 4 to 6 hours, the patient is referred for surgery using the shunt technique, where a bypass is created to drain the trapped blood in the corpora cavernosa into another vein or out of the body.
Non-ischemic priapism
Since there is no ischemia, it is not an emergency, and management is usually conservative initially. Many cases resolve spontaneously. Applying ice and gentle compression to the trauma area can help.
If the problem persists, the treatment of choice is a minimally invasive radiological procedure in which a catheter is guided to the damaged artery and occluded using coils or particles, thereby sealing the fistula. It has a high success rate and preserves erectile function.
Underlying cause and stuttering priapism
For recurrent priapism and to prevent new episodes in patients at risk, medications such as gonadotropin-releasing hormone (GnRH) agonists, antiandrogens, pseudoephedrine, and baclofen are used.
In sickle cell patients, aggressive hydration, oxygen therapy, and even an emergency blood transfusion may be necessary to treat the vaso-occlusive crisis.

Prevention of priapism
For patients using injectable medications for ED, the prescribed dosage and administration technique must be strictly followed.
If you are taking medication that is suspected of causing priapism, you should consult your doctor about adjusting the dose or changing the drug, but never stop taking the medication on your own.
Underlying conditions, especially sickle cell anemia, should be optimally managed. Avoid recreational drug use and alcohol abuse, and wear protective equipment during sports activities to prevent pelvic trauma.
Frequently Asked Questions (FAQs)
How long does priapism last?
Priapism is considered to be any erection that lasts more than 4h.
Is priapism always a medical emergency?
Yes, ischemic priapism is always a complete medical emergency. Non-ischemic priapism also requires urgent evaluation.
What should I do if I have a painful erection that won't go down?
Seek immediate medical attention at an emergency room, never wait for it to go away on its own.
Does priapism cause impotence?
Yes, it is the most common complication. The risk of permanent erectile dysfunction increases with the duration of the episode.
Does priapism affect male fertility?
Not directly, but the resulting erectile dysfunction can make intercourse difficult or impossible.
