penis damage
Introduction
Introduction Penile injury is not common and can be classified according to its location, extent, and anatomical pathology. Generally, according to the presence or absence of skin damage, it is divided into closed injury and open injury. Simple penile injury is rare, often combined with urethral injury, according to the presence or absence of skin damage is divided into closed injury and open injury, the former such as penile skin contusion, penis fracture, penis strangulation, and penile dislocation. The latter are such as knife cuts, stab wounds, bullet wounds, animal bites, and lacerations of rough sexual intercourse. The blood flow of the penis is very rich, and the viable tissue, especially the cavernous body, should be preserved as much as possible for replantation or reconstruction to restore the function of the penis.
Cause
Cause
Causes of penile injury:
The penile cutting can be seen in gunshot wounds, mechanical accidents, traffic accidents and injuries, as well as self-harm or castration. The latter is generally considered to be the most common cause.
Animal bites: Animal bites are rare. They used to occur in rural areas. Nowadays, because of the increase in people who like pets, bites by cats and dogs sometimes occur. It has been reported that animal bites in the United States account for 1% of emergency departments, of which 60% to 70% are children. Dog bites account for the majority, especially for penile scrotum.
Animal bites may cause avulsion of the penis skin, loss of the penis or combined urethral injury. May cause a potential hazard after injury, resulting in soft tissue damage, infection, urethral stricture and severe sexual function.

After the penis was disconnected, due to more blood loss, the patient's face was pale, the limbs were cold, the blood pressure dropped, and shock occurred. The penile stump is obviously bleeding, and it is not easy to stop bleeding. If the distal end of the disconnection is a trauma or an animal bite, the wound is not neat and the contusion is obvious; if the knife is cut and cut, the wound is neat and the replanting is easy to survive.
When the patient visits, ask whether there is any mental and neurological disease, the motivation of self-harm or the cause of the accident, the time of the cut-off, the amount of bleeding, the degree of damage, the blood circulation of the wound edge and the degree of local pollution, whether the perineum and scrotum are combined, Testicular damage and presence or absence of damage to the posterior urethra and bladder.
Diagnosis
Differential diagnosis
The diagnosis should be differentiated from the following symptoms:
1. Penile induration: Penile induration (Peyronie disease) was first reported in 1742, often in middle-aged men.
2. Penile abnormality: The abnormal penile erection (priapism) refers to the continuous erection of the penis unrelated to sexual desire. The penis continues to erect for more than 6 hours and is already an abnormal erection. Traditionally, abnormal penile erections are classified into primary (specific) and secondary. According to hemodynamics, it is divided into low blood flow type (ischemic) and high blood flow type (non-ischemic). Abnormal erection of the penis is also divided into acute, intermittent (recurrent or intermittent, such as sickle cell anemia) and chronic (usually high blood flow type). In the early stage of abnormal penile erection, it is a physiological penile erection, and later developed into a high blood flow type.
3. Penile pain: Penile pain mainly refers to the epidermis or internal pain of the penis. Some men will feel penile pain after the first sexual intercourse, then there is no need to be afraid. This may be because the penis is hyperemia after erection and the blood return function is weak, causing pain in the penis after sexual intercourse for a short time, usually 1 to 3 hours later. Can disappear. If you have sex many times during the first night of the wedding, this will happen. You can control the frequency of sexual life in the future.
