A prolonged erection of the penis, lasting more than 4 h, caused by a pathological condition or a drug.
An erection of the penis without sexual stimulus, caused by a blood clot in the tissue of the penis, injury to the spinal cord or stone in the urinary bladder.
Abnormal condition in which the penis is constantly erect, often with pain and seldom with sexual arousal; it may be caused by lesions in the central nervous system or the penis itself or be associated with certain systemic diseases.
Sustained, painful erection of the penis from a pathological state.
A painful, persistent erection not caused by sexual desire but by abnormal circulatory or neurologic condition, or drugs.
Persistent, painful erection of the penis without sexual desire or arousal. Priapism is a rare but serious condition caused by blood trapped in the penis. The condition primarily affects young men. Priapism can result from prolonged sexual activity, injury or infection in the genitals, certain medications, blood disease (leukemia, sickle cell anemia), cancer in the pelvis, a pool of clotted blood in the pelvis, or a tumor on the spine affecting the nerves that control erections. Prompt treatment is necessary to prevent severe, permanent injury to the penis. Immediate treatment consists of pain medication, drugs to reduce blood pressure, drawing blood from the penis through a needle, or injecting medication into the penis.
Persistent erection of the penis. It is commonly due to a blood clot in the erectile tissue of the penis and is most often encountered in patients with kidney failure undergoing intermittent dialysis. Treatment is by early surgical removal of the blood clot and the construction of a venous shunt to permit blood flow from the penis.
A persisting painful erection of the penis occurring without sexual stimulation. It is a rare but acute condition that requires immediate treatment. The cause is the failure of blood to drain from the spongy corpus cavernosum tissues of the penis, thus maintaining an erection. This may happen because of infection, damage to the nerves controlling the blood vessels, or a clotting defect in the blood.
Abnormal, painful, and continued erection of the penis caused by disease, occurring usually without sexual desire.
An enduring and painful erection of the penis that arises in the absence of sexual arousal. This is a hazardous condition necessitating immediate medical attention.
Priapism arises when the penis becomes erect, yet blood cannot exit the spongy tissue, leading to the inability of the erection to diminish. Potential causes encompass obstruction in the penile blood vessels due to conditions like sickle cell anemia, nerve impairment affecting the penis, or, on rare occasions, consequences stemming from treatments for erectile dysfunction.
Immediate intervention is essential to prevent lasting harm to the penile tissues. In some cases, blood can be drawn from the penis using a needle.
A prolonged, painful penile erection resulting from spinal cord disease or injuries, bladder stones, or penile trauma.
