  Priapism is a disorder in which the penis maintains a prolonged erection in the absence of appropriate stimulation. […] Ischemic causes of priapism are a true emergency and require prompt intervention to prevent damage to the penis, which can progress to erectile dysfunction and permanent impotence. […] Emergent management of this disease is directed toward achieving detumescence. […] Early intervention is essential for the functional recovery of erectile ability. If left untreated, penile corporal tissue necrosis and eventually fibrosis result along with permanent erectile dysfunction. […] The initial approach to ischemic priapism is to treat it as a true emergency. Any priapism episode lasting four hours or longer requires early intervention to decrease the likelihood of irreversible corporal damage and future erectile dysfunction.

  Priapism is a prolonged erection of the penis. The main types of priapism are ischemic and nonischemic. Ischemic priapism is a medical emergency. […] Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction). […] If you have an erection lasting more than four hours, you need emergency care. The emergency room doctor will determine whether you have ischemic priapism or nonischemic priapism. […] If you experience recurrent, persistent, painful erections that resolve on their own, see your doctor. You might need treatment to prevent further episodes. […] To prevent future episodes your doctor might recommend: Treatment for an underlying condition, such as sickle cell disease, that might have caused priapism; Use of oral or injectable phenylephrine; Hormone-blocking medications only for adult men; Use of oral medications used to manage erectile dysfunction.

  Appropriate treatment of priapism varies, depending on whether the patient has low-flow or high-flow priapism. Most priapism cases are the low-flow, ischemic type. […] Treatment of low-flow priapism should progress in a stepwise fashion, starting with therapeutic aspiration, with or without irrigation, followed by intracavernous injection of a sympathomimetic agent (phenylephrine). Repeated injection of a sympathomimentic agent should be performed before considering surgical intervention. […] Although all cases of priapism require prompt consultation with a genitourinary medicine specialist, emergency department (ED) personnel who have appropriate training and protocols may begin treatment with saline irrigation and injection. […] Treatment of high-flow priapism is initially conservative, as many cases will resolve spontaneously within several months. For persistent high-flow priapism, angiography with intervention to address arterial-spongiosum fistulae and/or pseudoaneurysm is the main treatment.

  If you have an erection lasting more than four hours, you need emergency care. […] The treatment for ischemic priapism needs to happen as soon as possible. […] Ischemic priapism the result of blood not being able to exit the penis is an emergency situation that requires immediate treatment. After pain relief, this treatment usually begins with a combination of draining blood from the penis and using medications. […] Excess blood is drained from your penis using a small needle and syringe (aspiration). […] A medication, such as phenylephrine, might be injected into your penis. […] If other treatments aren’t successful, a surgeon might perform other procedures to drain blood from the penis or surgery to reroute blood flow so that blood can again move through your penis. […] Nonischemic priapism often goes away with no treatment. […] Surgery might be necessary in some cases to insert material, such as an absorbable gel, that temporarily blocks blood flow to your penis.

  Priapism is a painful erection that lasts for several hours. It requires immediate medical treatment to prevent permanent damage to your penis. […] Priapism needs immediate treatment. Without treatment, it can cause permanent damage. […] The goal of all priapism treatment is to make your erection go away and preserve your ability to have erections in the future. If you think you have priapism, dont attempt to treat it yourself. Get emergency help as soon as possible. […] A healthcare provider may initially give you decongestants, such as phenylephrine (Sudafed PE). They can help decrease your erection by reducing blood flow to your penis. […] Other treatment options include: Draining excess blood from your penis (aspiration). A provider will first numb your penis. Theyll then use a small needle and syringe to withdraw oxygen-poor blood from your penis to reduce pressure and swelling.

  https://emedicine.medscape.com/article/437237-overview

  Priapism (see the image below) is an involuntarily prolonged erection that is unrelieved by orgasm/ejaculation. It can be generally divided into two subcategories: ischemic and nonischemic. Ischemic priapism, which constitutes approximately 95% of cases, is a true urologic emergency, and early intervention allows the best chance for functional recovery. […] Treatment should progress in a stepwise fashion, involving supportive care and the identification and treatment of reversible causes. […] Corporal aspiration with large-bore (18 gauge or greater) needle combined with intracavernosal phenylephrine (300-500 mcg every 5-10 min) is the first-line treatment of choice for low-flow priapism because it has almost pure alpha-agonist effects and minimal beta activity. […] If the above interventions are unsuccessful, a diluted solution of phenylephrine may be used for irrigation. If medical treatment fails, the condition warrants surgical intervention.

  Several medications can be utilized for ischemic priapism, and oral therapies such as pseudoephedrine may be tried while awaiting equipment and supplies for more advanced interventions. […] Aspiration and normal saline irrigation are recommended as the initial medical therapy. […] Intracavernosal drug therapy is generally the next step in priapism treatment. […] The American Urological Association Guidelines on priapism recommends an intracavernosal injection of 0.5 to 1 ml of a diluted phenylephrine concentration of 100 to 500 mcg/ml every 5 minutes for a total of up to 3 injections. […] Surgical intervention will be required if medical therapy fails. […] The „Corporal Snake Maneuver” can be tried if aspiration, irrigation, and shunting are unsuccessful. […] Penoscrotal decompression has recently been suggested as a better alternative shunting procedure that avoids trauma to the glans and distal corpora.

  In a patient with diagnosed acute ischemic priapism, conservative therapies (i.e., observation, oral medications, cold compresses, exercise) are unlikely to be successful and should not delay definitive therapies. Clinicians should counsel all patients with persistent acute ischemic priapism that there is the chance of erectile dysfunction. Clinicians should counsel patients with an acute ischemic priapism event 36 hours that the likelihood of erectile function recovery is low. […] Clinicians should manage acute ischemic priapism with intracavernosal phenylephrine and corporal aspiration, with or without irrigation, as first line therapy and prior to operative interventions. In patients receiving intracavernosal injections with phenylephrine to treat acute ischemic priapism, clinicians should monitor blood pressure and heart rate.

  Long-term, continuous use of phosphodiesterase type 5 (PDE5) inhibitors (eg, sildenafil), although off-label, has shown benefit in controlling recurrent ischemic priapism. […] Aspiration alone has a success rate of around 30%. […] If phenylephrine is not available, epinephrine can be used. […] Surgical ligation of the fistula is largely a historical procedure, but is reported in the literature. […] Distal shunt in the form of a transglanular-to-corpus cavernosal scalpel or needle-core biopsy (Ebbehoj or Winter technique) is the recommended approach for refractory cases. […] Prolonged low-flow priapism results in a variable degree of cavernosal fibrosis and a subsequent loss of penile length. The delayed insertion of a penile prosthesis can be difficult, with high complication rates. Immediate insertion of a penile prosthesis in patients with prolonged low-flow priapism is simple and maintains penile length.

  Clinicians should perform a distal corporoglanular shunt, with or without tunneling, in patients with persistent acute ischemic priapism after intracavernosal phenylephrine and aspiration, with or without irrigation. Clinicians should consider corporal tunneling in patients with persistent acute ischemic priapism after a distal corporoglanular shunt. Clinicians should counsel patients that there is inadequate evidence to quantify the benefit of performing a proximal shunt (of any kind) in a patient with persistent acute ischemic priapism after distal shunting. […] In an acute ischemic priapism patient with a persistent erection following shunting, the clinician should perform corporal blood gas or color duplex Doppler ultrasound prior to repeat surgical intervention to determine cavernous oxygenation or arterial inflow. Clinicians may consider placement of a penile prosthesis in a patient with untreated acute ischemic priapism greater than 36 hours or in those who are refractory to shunting, with or without tunneling. Clinicians should discuss the risks and benefits of early versus delayed placement with acute ischemic priapism patients who are considering a penile prosthesis.

  Orally administered pseudoephedrine is a first-line treatment for priapism. […] For those with ischemic priapism, the initial treatment is typically aspiration of blood from the corpus cavernosum. […] If aspiration is not sufficient, a small dose of phenylephrine may be injected into the corpus cavernosum. […] Distal shunts, such as the Winter’s, involve puncturing the glans (the distal part of the penis) into one of the cavernosa, where the old, stagnant blood is held. […] As the complication rates with prolonged priapism are high, early penile prosthesis implantation may be considered. […] In sickle cell anemia, treatment is initially with intravenous fluids, pain medication, and oxygen therapy.

  Early surgical intervention can be considered for patients with contraindications to alpha adrenergic therapy such as uncontrolled hypertension or use of monoamine oxidase inhibitors. […] The goal of any shunting procedure is to relieve venous outflow obstruction and subsequently restore blood flow to the corpora. […] Alternative to shunting, penoscrotal decompression (PSD), is a modern open approach to corporal decompression in episodes refractory ischemic priapism. […] PSD has demonstrated to be a viable option for prolonged ischemic priapism. […] In a multi-institutional study, Baumgarten et al. demonstrated 80% success rate of the 10 patients who underwent unilateral PSD and 100% success rate of 15 patients who underwent primary bilateral PSD in patients with mean duration of ischemic priapism at 71h.

  Surgical shunt. A surgeon can create a passageway in the penis to allow the blood to drain. Sometimes, several shunts are needed. Surgeons favor different techniques for creating and using these shunts. One of the techniques is called the corporal snake maneuver, which involves creating an expanded tunnel to drain the blood. These procedures are considered only when less aggressive treatments fail, as they can cause infections and raise the risk of lasting erectile dysfunction. […] For high-flow priapism, your doctor might recommend first watching and waiting to see if the erection goes away, which will happen in many cases. Other treatments might include: Ice packs and pressure. They may bring down swelling in the penis and surrounding areas. […] Blocking the artery. A doctor can block the blood vessel that’s causing the problem, using a procedure called arterial embolization. This doesn’t always work and can raise the risk of erectile dysfunction in the future. […] Tying off the artery. When a ruptured artery causes priapism, a doctor can do an operation to tie it off, called surgical ligation. This is less often recommended than embolization.

• #1 Priapism Emergency Treatment: Ischemic, Non-ischemic, Recurrent

  https://www.ebmedicine.net/topics/hepatic-renal-genitourinary/priapism-emergency

  Priapism is a genitourinary emergency that demands a thorough, time-sensitive evaluation. There are 3 types of priapism: ischemic, nonischemic, and recurrent ischemic priapism; ischemic priapism accounts for 95% of cases. Ischemic priapism must be treated within 4 to 6 hours to minimize morbidity, including impotence. […] This issue reviews current evidence regarding emergency department treatment of ischemic priapism using a stepwise approach that begins with aspiration of cavernosal blood, cold saline irrigation, and penile injection with sympathomimetic agents. Evidence-based management and appropriate urologic follow-up of nonischemic and recurrent ischemic priapism maximizes patient outcomes and resource utilization. […] Ischemic priapism represents a penile compartment syndrome, thus making it a true emergency requiring rapid intervention. Ischemic changes begin within 12 hours of a maintained erection, beginning with interstitial edema that progresses to denuding of the sinusoidal endothelium and thrombocyte adhesion at 24 hours. After approximately 48 hours, smooth-muscle necrosis occurs, and fibroblast-type cells proliferate. After 48 hours of ischemic priapism, 100% of patients develop some level of irreversible fibrosis of the corpus cavernosum that negatively affects their erectile function and can lead to permanent impotence.

  In addition, insertion of a penile prosthesis for recurrent stuttering priapism in SCD has also been described as effective in the long term. […] As cavernous tissue shows a well-oxygenated condition in non-ischemic priapism, it is not considered a medical emergency. Therefore, observation is recommended as the initial management. […] Some conservative treatments such as ice and site-specific compression to the injury are included as part of the observation therapy. […] Therefore, for cases that fail to respond to conservative treatments, selective angioembolization of the arterial-sinusoidal fistula should be considered.

  Ischemic priapism is considered a medical emergency and requires immediate treatment. If left untreated, the condition can significantly damage erectile function. […] In the early stages of ischemic priapism, a cold shower or ice pack may relieve symptoms. Exercise in the form of climbing stairs also may help. Medications, such as analgesics and opiates to control pain, may be recommended as well. […] Other treatments for the condition include: […] Intracavernous drug therapy. This treatment is often very effective in treating low-flow priapism. It involves injecting drugs known as alpha-agonists, such as diluted neosynephrine, into the penis, which causes the veins to open. As a result, the blood circulation to the penis is re-established. […] Shunt surgery. During this procedure, a surgical shunt is created to restore normal blood circulation. A surgical shunt creates a new route for the trapped blood to return to the body.

  Clinicians should counsel patients that non-ischemic priapism is not an emergency condition and should offer patients an initial period of observation. In a patient with diagnosed non-ischemic priapism, the clinician should consider penile duplex ultrasound for assessment of fistula location and size. In patients with persistent non-ischemic priapism after a trial of observation, and who wish to be treated, the clinician should offer embolization as first-line therapy. Non-ischemic priapism patients should be informed that embolization carries a risk of erectile dysfunction, recurrence, and failure to correct non-ischemic priapism.

  This condition does not require urgent treatment and in some cases, the condition may resolve itself spontaneously after days or months, at which point erectile capacity returns to normal. […] In some instances where treatment is necessary, the following procedures may be recommended: […] Embolization. This technique reduces blood flow in the penis by obstructing the ruptured artery. This may be achieved by having a radiologist insert specially designed coils, glues or spheres into the penis. […] Surgical ligation. The condition can also be treated by tying off the ruptured artery, which helps to restore normal blood flow in the penis.

  If the corporal aspiration procedure is not successful, sympathomimetics should be instilled into the corpus cavernosa. […] Ischemic priapism continuing for more than 48 hours is difficult to resolve by corporal aspiration, irrigation, and sympathomimetic injection. Thus, more immediate surgical shunting should be considered as another management option in such cases. […] The goal of surgical shunting is to make an iatrogenic fistula to drain the pooled deoxygenated blood from the corpora cavernosa. […] Stuttering priapism is a recurrent form of ischemic priapism in which unwanted, painful erections occur repeatedly with intervening periods of detumescence. Therefore, its medical management is generally equivalent to that of ischemic priapism.

  Stuttering priapism is an uncommon but potentially severe condition that causes frequent, short-lived erections which may last under 3 to 4 hours at a time. […] This progression requires immediate treatment to prevent problems such as erectile dysfunction. […] Therefore, its suggested for patients to get treated within 4 hours to lessen the risk of long-term complications or permanent damage to the erecting structures or corpora of the penis. […] The main aim in treating the type of long-lasting, recurring erections known as stuttering priapism is to prevent future instances from occurring. Emergency treatment is crucial when a person experiences an episode of this condition where the erection lasts more than four hours. […] Recent breakthroughs in understanding how stuttering priapism works have allowed medical researchers to test new medications. […] Hormonal treatments work by reducing the levels of testosterone in the body. A study has shown that drastically reducing testosterone levels can help reduce the number of priapism episodes. […] Other treatment options for stuttering priapism include injections of diluted pseudoephedrine directly into the tissues of the penis. […] Studies have shown that a low daily dose of sildenafil can help regulate blood flow and prevent episodes of priapism in both men with and without SCD. […] Finally, in severe or stubborn cases where other methods have failed, there are surgical options such as the placement of a penile prosthesis. […] Stuttering priapism, a condition involving abnormal, prolonged penile erections, only leads to erectile dysfunction (ED) in about one-quarter of patients. […] It’s crucial to seek medical help if you’re experiencing symptoms of priapism to avoid potential complications.

• #1 How I treat priapism

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4458797/

  Priapism is a disorder of persistent penile erection unrelated to sexual interest or desire. This pathologic condition, specifically the ischemic variant, is often associated with devastating complications, notably erectile dysfunction. […] Thus, timely diagnosis and management are critical for the prevention or at least reduction of cavernosal tissue ischemia and potential damage consequent to each episode. Current guidelines and management strategies focus primarily on reactive treatments. However, an increasing understanding of the molecular pathophysiology of SCD-associated priapism has led to the identification of new potential therapeutic targets. Future agents are being developed and explored for use in the prevention of priapism. […] When episodes are unremitting, increasingly invasive options are used in an attempt to prevent worsening tissue damage and preserve erectile function or simply provide palliative care when erectile function can no longer be preserved.

  Priapism (see the image below) is an involuntarily prolonged erection that is unrelieved by orgasm/ejaculation. It can be generally divided into two subcategories: ischemic and nonischemic. Ischemic priapism, which constitutes approximately 95% of cases, is a true urologic emergency, and early intervention allows the best chance for functional recovery. […] Treatment should progress in a stepwise fashion, involving supportive care and the identification and treatment of reversible causes. […] Corporal aspiration with large-bore (18 gauge or greater) needle combined with intracavernosal phenylephrine (300-500 mcg every 5-10 min) is the first-line treatment of choice for low-flow priapism because it has almost pure alpha-agonist effects and minimal beta activity. […] If the above interventions are unsuccessful, a diluted solution of phenylephrine may be used for irrigation. If medical treatment fails, the condition warrants surgical intervention.

  Ischemic priapism is typically treated with a nerve block of the penis followed by aspiration of blood from the corpora cavernosa. […] If this is not sufficient, the corpus cavernosum may be irrigated with cold, normal saline or injected with phenylephrine. […] Nonischemic priapism is often treated with cold packs and compression. […] Surgery may be done if usual measures are not effective. […] In ischemic priapism, the risk of permanent scarring of the penis begins to increase after four hours and definitely occurs after 48 hours. […] 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 nonischemic priapism, cold packs and pressure to the area may be sufficient.

  Priapism is a long-lasting erection of the penis that is usually painful. It becomes a medical emergency if it goes on for several hours. […] The immediate goal of treatment is to make the erection go away and prevent permanent damage. While you might feel embarrassed about heading to the emergency room with an obvious erection, you shouldn’t try to treat it by yourself at home. The risk of permanent damage to your penis is too high. […] For low-flow priapism, effective treatments can include: Removing the blood. After your doctor numbs your penis, they’ll use a needle to drain blood from the area to ease pressure and swelling. They might also flush out the blood with a saline solution. They may have to do these things several times to give you relief. […] Medicines. Your doctor can inject drugs called alpha-agonists into your penis. The drugs make the arteries narrow, bringing less blood to the area and easing swelling. Side effects can include headache, dizziness, and high blood pressure.

  Priapism is an uncontrolled, prolonged erection of the penis thats usually painful and continues beyond, or may not even be associated with, sexual stimulation. Priapism often requires intervention and can cause damage if left untreated. […] Acute ischemic, or low-flow, priapism is caused by restricted venous outflow from the corpus cavernosa of the penis, leading to painful engorgement and limited arterial blood flow. Prolonged ischemic priapism requires emergency treatment to prevent damage to penile tissue that can result in erectile dysfunction. […] First-line therapy for ischemic priapism is corporal aspiration and intracavernosal injection (ICI) with phenylephrine, with or without saline irrigation. This should occur immediately after diagnosis. […] Surgical management should be considered early after diagnosis, especially in cases where priapism has lasted more than 36 hours. The recommended surgical intervention for ischemic priapism is a distal corporoglanular shunt, with or without tunneling.

  Surgical shunt. A surgeon can create a passageway in the penis to allow the blood to drain. Sometimes, several shunts are needed. Surgeons favor different techniques for creating and using these shunts. One of the techniques is called the corporal snake maneuver, which involves creating an expanded tunnel to drain the blood. These procedures are considered only when less aggressive treatments fail, as they can cause infections and raise the risk of lasting erectile dysfunction. […] For high-flow priapism, your doctor might recommend first watching and waiting to see if the erection goes away, which will happen in many cases. Other treatments might include: Ice packs and pressure. They may bring down swelling in the penis and surrounding areas. […] Blocking the artery. A doctor can block the blood vessel that’s causing the problem, using a procedure called arterial embolization. This doesn’t always work and can raise the risk of erectile dysfunction in the future.

[…] Therefore, its suggested for patients to get treated within 4 hours to lessen the risk of long-term complications or permanent damage to the erecting structures or corpora of the penis. […] The main aim in treating the type of long-lasting, recurring erections known as stuttering priapism is to prevent future instances from occurring. Emergency treatment is crucial when a person experiences an episode of this condition where the erection lasts more than four hours. […] Recent breakthroughs in understanding how stuttering priapism works have allowed medical researchers to test new medications. […] Hormonal treatments work by reducing the levels of testosterone in the body. A study has shown that drastically reducing testosterone levels can help reduce the number of priapism episodes. […] Other treatment options for stuttering priapism include injections of diluted pseudoephedrine directly into the tissues of the penis. […] Studies have shown that a low daily dose of sildenafil can help regulate blood flow and prevent episodes of priapism in both men with and without SCD. […] Finally, in severe or stubborn cases where other methods have failed, there are surgical options such as the placement of a penile prosthesis.

  Priapism is a genitourinary emergency that demands a thorough, time-sensitive evaluation. There are 3 types of priapism: ischemic, nonischemic, and recurrent ischemic priapism; ischemic priapism accounts for 95% of cases. Ischemic priapism must be treated within 4 to 6 hours to minimize morbidity, including impotence. […] This issue reviews current evidence regarding emergency department treatment of ischemic priapism using a stepwise approach that begins with aspiration of cavernosal blood, cold saline irrigation, and penile injection with sympathomimetic agents. Evidence-based management and appropriate urologic follow-up of nonischemic and recurrent ischemic priapism maximizes patient outcomes and resource utilization. […] Ischemic priapism represents a penile compartment syndrome, thus making it a true emergency requiring rapid intervention. Ischemic changes begin within 12 hours of a maintained erection, beginning with interstitial edema that progresses to denuding of the sinusoidal endothelium and thrombocyte adhesion at 24 hours. After approximately 48 hours, smooth-muscle necrosis occurs, and fibroblast-type cells proliferate. After 48 hours of ischemic priapism, 100% of patients develop some level of irreversible fibrosis of the corpus cavernosum that negatively affects their erectile function and can lead to permanent impotence.
