Priapism
Priapism is a persistent erection that lasts for more than four hours, not resulting from sexual stimulation. It is a medical emergency that requires prompt medical attention. Priapism is divided into two types; ischemic priapism and non-ischemic priapism. Ischemic priapism is the most common type and happens when blood flow to the penis is blocked, causing tissue damage if not treated promptly. Non-ischemic priapism, on the other hand, occurs due to trauma or injury to the penis. Priapism can affect males of all ages, and the symptoms may vary from mild to severe pain or discomfort. The diagnosis is usually made by physical examination, and treatment may include medication, aspiration or surgery. However, untreated priapism may lead to permanent erectile dysfunction, making prompt medical attention critical in such situations.
Symptoms of Priapism
What are the common symptoms of priapism?
Priapism is a persistent, painful erection that lasts for more than four hours and is not related to sexual arousal. The common symptoms of priapism include a painful erection that lasts for several hours, tenderness or swelling in the penis, and difficulty urinating.
What medical conditions can cause priapism?
Several medical conditions can cause priapism, including sickle cell anemia, leukemia, spinal cord injury, pelvic tumors, and certain blood clotting disorders. Hormonal imbalances, such as a pituitary gland disorder or testosterone deficiency, can also cause priapism.
Can drug abuse lead to priapism?
Yes, drug abuse can lead to priapism. Certain medications, such as antidepressants, anticoagulants, and blood pressure medications, can increase the risk of priapism. Cocaine and other recreational drugs can also cause priapism.
Is sickle cell anemia a common cause of priapism?
Yes, sickle cell anemia is a common cause of priapism. Sickle cell anemia is a genetic blood disorder that affects the shape of red blood cells, leading to episodes of severe pain, organ damage, and other complications. Priapism is a common complication of sickle cell anemia and affects up to 40% of men with the condition.
How does trauma to the genital area lead to priapism?
Trauma to the genital area can lead to priapism by causing blood vessels in the penis to rupture or become blocked. This can occur due to injuries such as falls, accidents, or sexual abuse. In some cases, trauma can also cause structural damage to the penis, leading to erection problems and priapism.
Diagnosis of Priapism
How is priapism diagnosed?
Priapism can be diagnosed by a physical examination, medical history evaluation, and blood tests. A doctor will assess the patient`s genitals to determine the type, extent, and duration of the erection. They may also ask about any medications or drug use, as well as medical history.

Can a physical exam alone diagnose priapism or are further tests necessary?
Blood tests can be done to test for conditions that may contribute to priapism, such as sickle cell disease. The tests may include a complete blood count (CBC), liver function tests, and toxicology screening.
Treatments of Priapism
What are the initial steps for managing priapism?
The initial steps for managing priapism include a thorough medical history and physical examination to identify the underlying cause. In most cases, conservative measures such as ice packs, hydration, and pain relief with analgesics are recommended. If these measures are ineffective, medical intervention may be necessary.
How can aspiration and injection be used to treat priapism?
Aspiration and injection are used as second-line treatments for priapism. Aspiration involves withdrawing blood from the penis using a syringe and needle, while injection involves injecting a medication directly into the penis to cause constriction of blood vessels and improve blood flow. These procedures should only be performed by a healthcare professional and may be accompanied by sedation or anesthesia.
What medications are commonly used to manage priapism?
The medications most commonly used to manage priapism include phenylephrine and ephedrine, which work by causing constriction of the blood vessels in the penis. These medications are generally administered via injection and should only be used under the supervision of a healthcare professional.
When is surgery necessary for the treatment of priapism?
Surgery is necessary for the treatment of priapism when conservative measures and medical interventions have failed. The surgical options for priapism include shunting procedures, which involve creating a passage between the corpora cavernosa and the spongiosum to improve blood flow, and penile implantation, which is indicated in cases of recurrent priapism.
What is the recovery time for patients undergoing surgical treatment for priapism?
The recovery time for patients undergoing surgical treatment for priapism depends on the type of procedure performed and the patient`s individual circumstances. Generally, patients can expect to experience some pain and discomfort after surgery and may need to avoid sexual activity and strenuous exercise for several weeks. It is important to follow all post-operative instructions provided by the healthcare professional and attend all follow-up appointments to ensure proper healing and recovery.
Prognosis of Priapism
Is the long-term prognosis of priapism favorable?
Priapism is a relatively rare condition characterized by prolonged and non-sexual erections that can last for several hours or even days. The condition can be classified into two types, namely ischemic and non-ischemic priapism. While non-ischemic priapism has a favorable prognosis and generally resolves within a few days without causing any long-term complications, ischemic priapism can cause severe damage to the penis tissues leading to permanent impotence, known as erectile dysfunction. According to a retrospective study, the overall long-term prognosis of priapism is fair, and around 76% of patients experience resolution of priapism-related complications within one year of treatment.

What is the mortality rate associated with priapism?
Priapism is considered a medical emergency that requires prompt intervention because it can cause severe complications, such as erectile dysfunction and penile necrosis. However, mortality associated with priapism is relatively rare. A systematic review of the literature revealed that the overall mortality rate associated with priapism is less than 1% and is usually associated with underlying conditions such as sickle cell anemia and leukemia.

Can priapism lead to impotence?
Priapism can cause permanent damage to the penile tissues, leading to erectile dysfunction, which can prevent men from achieving a sustainable erection for sexual intercourse. Prolonged erections that last for several hours or days can cause ischemia, lack of oxygen supply to the tissues, and tissue damage. This damage can cause fibrosis of the cavernous tissue, leading to irreversible impotence. Hence, priapism is considered a urologic emergency and requires prompt treatment to prevent long-term mechanical dysfunction. Source: https://emedicine.medscape.com/article/437260-overview#a3
How often does priapism recur after treatment?
Recurrence of priapism after treatment is relatively common, particularly in patients with sickle cell anemia, a congenital blood disorder that significantly increases the risk of priapism. A retrospective study conducted on patients with sickle cell anemia-induced priapism found that approximately 40% of patients had recurrent priapism within six months of treatment.

Does early intervention improve the prognosis of priapism?
Early intervention is crucial in treating priapism, particularly ischemic priapism. The goal of early intervention is to restore blood flow to the penis and minimize the risk of long-term complications such as erectile dysfunction. Several treatment options are available, including medication, aspiration, and surgery. As per the American Urological Association guidelines, early intervention with a penile injection of sympathomimetics is the preferred approach for the management of priapism. Delayed intervention can lead to irreversible damage to the cavernous tissues, which can cause long-term mechanical dysfunction and impotence.

Prevention of Priapism
What actions can be taken to prevent priapism?
Priapism is a condition where the penis remains erect for an extended period without sexual arousal or stimulation. To prevent priapism, individuals should avoid recreational drugs, primarily cocaine and other stimulants, as they can trigger priapism. Further, individuals with sickle cell disease should follow appropriate medical protocols to have their blood checked regularly, as sickle cell anemia is one of the leading causes of priapism.
Are there any medications or lifestyle changes that can decrease the risk of priapism?

How can medical providers educate patients on priapism prevention?
There are some medications and lifestyle changes that can prevent or decrease the risk of priapism. Patients should avoid taking medications that increase the risk of priapism, such as antipsychotics and antidepressants. However, if medication is necessary, physicians may prescribe medications that can help prevent priapism or reduce the duration of priapism events, such as pseudoephedrine. Lifestyle changes can include regular exercise and reducing the frequency of alcohol consumption.
Is there a correlation between priapism prevention and prior medical history?

Can preventative measures be implemented during sexual activity to reduce the likelihood of priapism?
Physicians can educate their patients on priapism prevention by informing them of the potential triggers, such as recreational drug use, and assessing the individual`s risk of priapism based on their medical history. Physicians should also educate male patients with sickle cell disease about the potential risk of priapism and the importance of regularly monitoring their blood counts.
