• #8 Priapism Clinical Presentation: History, Physical Examination, Complications

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

  Patients presenting with priapism will report a persistent erection. Accompanying symptoms depend on the type of priapism and the duration of engorgement. Low-flow, ischemic-type priapism, which comprises 95% of priapism cases, is generally painful. However, with prolonged episodes the pain may disappear, due to paralysis and eventual death of sensory nerves in the penis. High-flow, nonischemic priapism is almost never painful. […] Historical features of low-flow priapism include the following: Painful. […] The most common long-term complication of priapism and its treatment is erectile dysfunction (ED). Patients should be counseled based on type of priapism and the duration of erection (less than or longer than 24 hours) regarding their risk of permanent ED. For patients with prolonged ischemic priapism ( 24 h), the expectation of ED should be disclosed early in the treatment course and close followup with a urologist specializing in prosthetic urology should be recommended and coordinated. […] In patients with nonischemic priapism who ultimately undergo angiography with embolization of the fistula/pseudoaneurysm, ED is common. Although it may be transient, it may be permanent and lead to the need for penile implant insertion to permit penetrative intercourse.

  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. Priapism is a disorder in which the penis maintains a prolonged, rigid erection in the absence of appropriate stimulation. Definitions vary regarding duration, but any erection lasting four hours or longer is generally considered priapism. Ischemic causes of priapism are a true emergency and require prompt intervention to prevent damage to the penis, which can progress to complete and permanent erectile dysfunction. 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. Priapism does not generally cause engorgement of the glans penis and corpus spongiosum because these structures have a separate venous drainage system. While priapism is usually defined as an erection that lasts 4 hours or longer, physiological changes and microscopic tissue damage inside the penis typically do not start until about 6 hours after onset. Permanent structural changes of the corporal smooth muscle tissue start to develop after 12 hours, beginning with trabecular interstitial edema. Cellular damage begins 24 hours after priapism initiation with basement membrane skeletonization, increased platelet adherence, and sinusoidal endothelial destruction. Thrombus collections in the sinusoidal spaces and direct damage to cavernosal smooth muscle tissue leading to fibrosis and permanent ED begin within 36 hours. Early treatment and detumescence generally do not result in long-term erection problems. If the priapism lasts longer than 24 hours, permanent damage begins, and up to 90% of such men cannot have normal sexual intercourse afterward. Recurrent priapism, also called „stuttering priapism,” is usually ischemic and quite uncommon. It tends to be associated with sickle cell disease and, rarely, cannabis use. Recurrent priapism typically occurs at night with relatively short periods of erectile rigidity, which gradually tend to develop longer durations. The exact pathophysiological mechanism of this type of priapism is not well understood but is thought to be an intracavernosal regulatory problem involving phosphodiesterase type 5 and nitric oxide. Stuttering priapism is relatively common in sickle cell patients. The typical duration is anywhere from a few minutes to three hours and generally tends to be painful but self-limiting. Repeated episodes of ischemic priapism can lead to permanent penile damage and erectile dysfunction, which occurs in up to 40% of affected patients. Long-term erectile dysfunction due to damage from prolonged priapism is possible. The longer the duration of the priapism, the greater the damage to corpora cavernosal tissues.

• #10 Priapism: Treatment, causes, symptoms, and types

  https://www.medicalnewstoday.com/articles/318737

  Priapism is a prolonged and potentially painful erection. It causes blood in the penis to become trapped and unable to drain through the penile arteries. […] The main symptom is a prolonged erection unrelated to sexual activity or interest. […] Symptoms of ischemic priapism include: penile pain that gets worse with time, an erection where the tip of the penis remains soft. […] It is important for someone who has had an erection, for 4 hours or more, to seek immediate emergency care. The blood trapped in the penis does not have oxygen, which means that the penile tissue is deprived of oxygen and can become damaged or even destroyed. […] Without prompt treatment, permanent nerve damage and erectile dysfunction can occur. […] Tissue damage can begin 4-6 hours after onset, so it is important to avoid delay in getting emergency help. Any damage to the sensitive penile tissue is permanent and cannot be reversed.

  Painful erections (also referred to as priapism) refer to the prolonged erection of male penis for an extended period of time (sometimes up to a few hours) with or without sexual stimulation. It usually affects males in their 30s. Painful and prolonged erections if not treated in a timely fashion can damage your penis permanently. […] The symptoms of Priapism may vary. There are two clinical types of Priapism: Ischemic Priapism and Nonischemic Priapism. […] Ischemic Priapism is a low flow Priapism in which blood vessels gets weak and impedes the flow of blood to and from penis. It is a more common type of Priapism. Sign and symptoms includes Erection that lasts more than four hours without stimulation. The penile shaft is rigid but the tip remains soft. Pain in penis. […] The ischemic Priapism might become a recurrent condition. It is more common in sickle cell anemia patients. This disease obstructs the blood vessel in the penis. In the beginning the unwanted erection occur for shorter durations (up to a few minutes) but with time, the condition may worsen and painful erections may occur more frequently and for long durations.

  https://www.healthline.com/health/priapism

  The main difference between low-flow and high-flow priapism is that pain doesn’t occur with high-flow priapism. […] Ischemic or low-flow priapism is considered a medical emergency and requires treatment, which may involve aspiration to remove excess blood, medications, or surgery. […] If left untreated, the risk of tissue damage and permanent erectile dysfunction may increase.

• #34 Priapism Clinical Presentation: History, Physical Examination, Complications

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

  Patients presenting with priapism will report a persistent erection. Accompanying symptoms depend on the type of priapism and the duration of engorgement. Low-flow, ischemic-type priapism, which comprises 95% of priapism cases, is generally painful. However, with prolonged episodes the pain may disappear, due to paralysis and eventual death of sensory nerves in the penis. High-flow, nonischemic priapism is almost never painful. […] Historical features of low-flow priapism include the following: Painful. […] The most common long-term complication of priapism and its treatment is erectile dysfunction (ED). Patients should be counseled based on type of priapism and the duration of erection (less than or longer than 24 hours) regarding their risk of permanent ED. For patients with prolonged ischemic priapism ( 24 h), the expectation of ED should be disclosed early in the treatment course and close followup with a urologist specializing in prosthetic urology should be recommended and coordinated. […] In patients with nonischemic priapism who ultimately undergo angiography with embolization of the fistula/pseudoaneurysm, ED is common. Although it may be transient, it may be permanent and lead to the need for penile implant insertion to permit penetrative intercourse.

• #35 What You Need To Know About Priapism

  http://urologyspecialist.com.au/priapism-explained/

  Priapism is a relatively rare condition involving an erection that lasts for an unusually long time which can usually be quite painful and unrelated to sexual stimulus. Immediate treatment is essential to prevent tissue damage and erectile dysfunction. […] The symptoms of Priapism will vary depending on the type of Priapism. However, the two main types of Priapism are ischemic and nonischemic. […] Ischemic: the result of blood not being able to leave the penis. Symptoms include an erection lasting more than four hours with a rigid shaft but a soft tip and progressive pain in the penis. Some men may also experience ischemic Priapism recurrently, with symptoms worsening each time. […] Nonischemic: occurs when blood flow to the penis is not regulated correctly in the body. Nonischemic Priapism is not as common as ischemic cases; however, it is usually less painful and poses far less risk. Signs and symptoms include an erection lasting more than four hours with an erect but not fully rigid shaft.

  In some cases, the condition starts off with unwanted and painful erections of short duration and might progress over time to more-frequent and more-prolonged erections. […] If you experience recurrent, persistent, painful erections that resolve on their own, see your doctor. […] Ischemic priapism can cause serious complications. The blood trapped in the penis is deprived of oxygen. […] When an erection lasts for too long usually more than four hours this lack of oxygen can begin to damage or destroy tissues in the penis. […] Priapism, usually ischemic priapism, is a possible side effect of a number of drugs. […] A common cause of nonischemic priapism is trauma or injury to your penis, pelvis, or the region between the base of the penis and the anus (perineum). […] Nonischemic priapism often goes away with no treatment. […] Because there isn’t a risk of damage to the penis, your doctor might suggest a watch-and-wait approach. […] If you have sickle cell disease, you might receive additional treatments that are used to treat disease-related episodes.

  Priapism is a partial or full erection that lasts for four hours or more without sexual stimulation. […] While nonischemic priapism isn’t painful, ischemic priapism tends to be very painful. Pain typically worsens the longer the erection lasts. […] Ischemic priapism is painful and considered a medical emergency. This is the more common of the two types of priapism. […] Ischemic priapism can be very painful – and pain tends to worsen the longer the erection persists. […] One type of ischemic priapism is stuttering priapism, which is when men have repeated episodes of ischemic priapism most commonly associated with sickle cell disease. […] These erections also have a tendency to be painful and uncomfortable. […] Nonischemic priapism doesn’t tend to be painful and will often go away without medical intervention.

• #38 Priapism: Treatment, causes, symptoms, and types

  https://www.medicalnewstoday.com/articles/318737

  Priapism is a prolonged and potentially painful erection. It causes blood in the penis to become trapped and unable to drain through the penile arteries. […] The main symptom is a prolonged erection unrelated to sexual activity or interest. […] Symptoms of ischemic priapism include: penile pain that gets worse with time, an erection where the tip of the penis remains soft. […] It is important for someone who has had an erection, for 4 hours or more, to seek immediate emergency care. The blood trapped in the penis does not have oxygen, which means that the penile tissue is deprived of oxygen and can become damaged or even destroyed. […] Without prompt treatment, permanent nerve damage and erectile dysfunction can occur. […] Tissue damage can begin 4-6 hours after onset, so it is important to avoid delay in getting emergency help. Any damage to the sensitive penile tissue is permanent and cannot be reversed.

  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. Priapism is a disorder in which the penis maintains a prolonged, rigid erection in the absence of appropriate stimulation. Definitions vary regarding duration, but any erection lasting four hours or longer is generally considered priapism. Ischemic causes of priapism are a true emergency and require prompt intervention to prevent damage to the penis, which can progress to complete and permanent erectile dysfunction. 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. Priapism does not generally cause engorgement of the glans penis and corpus spongiosum because these structures have a separate venous drainage system. While priapism is usually defined as an erection that lasts 4 hours or longer, physiological changes and microscopic tissue damage inside the penis typically do not start until about 6 hours after onset. Permanent structural changes of the corporal smooth muscle tissue start to develop after 12 hours, beginning with trabecular interstitial edema. Cellular damage begins 24 hours after priapism initiation with basement membrane skeletonization, increased platelet adherence, and sinusoidal endothelial destruction. Thrombus collections in the sinusoidal spaces and direct damage to cavernosal smooth muscle tissue leading to fibrosis and permanent ED begin within 36 hours. Early treatment and detumescence generally do not result in long-term erection problems. If the priapism lasts longer than 24 hours, permanent damage begins, and up to 90% of such men cannot have normal sexual intercourse afterward. Recurrent priapism, also called „stuttering priapism,” is usually ischemic and quite uncommon. It tends to be associated with sickle cell disease and, rarely, cannabis use. Recurrent priapism typically occurs at night with relatively short periods of erectile rigidity, which gradually tend to develop longer durations. The exact pathophysiological mechanism of this type of priapism is not well understood but is thought to be an intracavernosal regulatory problem involving phosphodiesterase type 5 and nitric oxide. Stuttering priapism is relatively common in sickle cell patients. The typical duration is anywhere from a few minutes to three hours and generally tends to be painful but self-limiting. Repeated episodes of ischemic priapism can lead to permanent penile damage and erectile dysfunction, which occurs in up to 40% of affected patients. Long-term erectile dysfunction due to damage from prolonged priapism is possible. The longer the duration of the priapism, the greater the damage to corpora cavernosal tissues.

  Priapism is defined as a prolonged erection developing in the absence of sexual stimulation and unrelieved by ejaculation. […] Ischemic priapism results from the failure of blood to drain from the erect penis. […] Over time, the lack of oxygenated blood flow to the penis results in irreversible structural changes with in the erectile tissue leading to tissue death and scarring. […] It is believed that even after 6-8 hours of ischemic priapism irreversible damage begins to occur. […] Erections lasting longer than 4-6 hours are associated with permanent erection problems. […] It has been estimated that priapism of 24 hours duration is associated with an approximately 50% incidence of permanent erectile dysfunction. […] The patient with ischemic priapism typically complains of a painful erection, which is fully rigid. […] Men with non-ischemic priapism have an erection that is usually less than fully rigid and painless.

Priapism can affect males of all ages, but it is most common in men between the ages of 20 and 50. […] This prolonged erection is painful and can damage the penis permanently if not treated promptly. […] The main symptom of priapism is a persistent and painful erection that lasts for more than four hours. Other symptoms may include swelling and tenderness in the penis, difficulty urinating, fever, chills, rapid heartbeat, and shortness of breath. […] Ischemic priapism is usually painful and can last for several hours or even days if left untreated. […] If left untreated or not treated adequately, priapism can lead to several complications, including erectile dysfunction. Priapism can cause permanent damage to the tissues and nerves in the penis, leading to long-term erectile dysfunction. […] Prolonged and untreated priapism can lead to the formation of scar tissue in the penis, causing a condition called fibrosis. This can result in a curvature of the penis during erection, making sexual intercourse difficult or impossible.

  Priapism is a prolonged and painful erection of the penis that is not associated with sexual stimulation and can last between at least four hours to several days. It occurs when the penis begins to fill with blood, as it would during a normal erection, but the blood does not drain properly as the sex organs become blocked, or the systems that relax the organs fail. […] Ischaemic priapism (or low-flow priapism) is the most common type and occurs when the blood is unable to leave the penis. An erection tends to last more than four hours, the shaft is rigid but the tip of the penis is soft. It causes progressive penile pain. […] Although the main feature of this pathology is the unwanted erection lasting several hours, the symptoms vary depending on the type of priapism.

  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. Priapism is a disorder in which the penis maintains a prolonged, rigid erection in the absence of appropriate stimulation. Definitions vary regarding duration, but any erection lasting four hours or longer is generally considered priapism. Ischemic causes of priapism are a true emergency and require prompt intervention to prevent damage to the penis, which can progress to complete and permanent erectile dysfunction. 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. Priapism does not generally cause engorgement of the glans penis and corpus spongiosum because these structures have a separate venous drainage system. While priapism is usually defined as an erection that lasts 4 hours or longer, physiological changes and microscopic tissue damage inside the penis typically do not start until about 6 hours after onset. Permanent structural changes of the corporal smooth muscle tissue start to develop after 12 hours, beginning with trabecular interstitial edema. Cellular damage begins 24 hours after priapism initiation with basement membrane skeletonization, increased platelet adherence, and sinusoidal endothelial destruction. Thrombus collections in the sinusoidal spaces and direct damage to cavernosal smooth muscle tissue leading to fibrosis and permanent ED begin within 36 hours. Early treatment and detumescence generally do not result in long-term erection problems. If the priapism lasts longer than 24 hours, permanent damage begins, and up to 90% of such men cannot have normal sexual intercourse afterward. Recurrent priapism, also called „stuttering priapism,” is usually ischemic and quite uncommon. It tends to be associated with sickle cell disease and, rarely, cannabis use. Recurrent priapism typically occurs at night with relatively short periods of erectile rigidity, which gradually tend to develop longer durations. The exact pathophysiological mechanism of this type of priapism is not well understood but is thought to be an intracavernosal regulatory problem involving phosphodiesterase type 5 and nitric oxide. Stuttering priapism is relatively common in sickle cell patients. The typical duration is anywhere from a few minutes to three hours and generally tends to be painful but self-limiting. Repeated episodes of ischemic priapism can lead to permanent penile damage and erectile dysfunction, which occurs in up to 40% of affected patients. Long-term erectile dysfunction due to damage from prolonged priapism is possible. The longer the duration of the priapism, the greater the damage to corpora cavernosal tissues.

  Patients with SRPE will be awakened by painful erections during sleep, which affects their sleep process and general health. […] Sleep-related painful erection (SRPE) is a rare condition which sees patients experiencing frequent erections during rapid eye movement (REM) sleep causing deep penile pain and interrupted sleep. […] Patients with SRPE often have the clinical characteristics of repeated waking during REM sleep accompanied by painful erections. […] SRPE needs to be differentiated from priapism, which is a persistent, often painful penile erection that lasts more than 4 hours and has nothing to do with sexual stimulation. […] In ischemic penile priapism, the cavernous body is stiff, the glans and cavernous body are relaxed, and there is interstitial pressure and damage to the microvessels leading to penile fascial compartment syndrome. […] Symptoms include evident stiffness of the cavernous body, disordered venous blood outflow, and persistent painful erection, which may cause the trabeculae of the cavernous body of the penis to be exposed to ischemic blood when persistent.

  Men with Stuttering Priapism (SP) and sleep-related painful erections (SRPE) experience bothersome nocturnal painful erections resulting in poor sleep. […] Men with SP had significantly longer erections (60.0 vs 18.5; p=0.002) and took longer to detumesce once awake (25.7 vs 5.4min; p=0.001) than men with SRPE. […] Painful and bothersome nocturnal erections that result in poor sleep and daytime tiredness were experienced by all men in this study. […] The pain experienced by the men with SP is ischemic in origin. […] Men in this group have all had a previous corporal blood gas analysis that confirmed ischemia. […] They also have significantly longer nocturnal erections (60min) and once awake took a significantly longer time to detumesce (25.7min) when compared to men with SRPE. […] In men with SRPE the total duration was 18.5min and the erection persisted after waking for 5.4min.

  It would therefore be highly unlikely for an erection of 18.5min to cause sufficient ischemia to result in pain that wakes up the patient. […] It is therefore likely that pain experienced by men with SRPE is from a nonischemic cause. […] It was also noted that the symptoms of men with SP were worse in the second half of their nights sleep. […] Differences in the sleep architecture between the two groups was also identified. Sleep-related erections occurred during REM sleep in both groups. […] Men with SRPE also had significantly higher PLM during sleep than men with SP.

• #98 Priapism: Treatment, causes, symptoms, and types

  https://www.medicalnewstoday.com/articles/318737

  Priapism is a prolonged and potentially painful erection. It causes blood in the penis to become trapped and unable to drain through the penile arteries. […] The main symptom is a prolonged erection unrelated to sexual activity or interest. […] Symptoms of ischemic priapism include: penile pain that gets worse with time, an erection where the tip of the penis remains soft. […] It is important for someone who has had an erection, for 4 hours or more, to seek immediate emergency care. The blood trapped in the penis does not have oxygen, which means that the penile tissue is deprived of oxygen and can become damaged or even destroyed. […] Without prompt treatment, permanent nerve damage and erectile dysfunction can occur. […] Tissue damage can begin 4-6 hours after onset, so it is important to avoid delay in getting emergency help. Any damage to the sensitive penile tissue is permanent and cannot be reversed.
