penis amputation
Introduction
Introduction to penile injury The so-called penile injury refers to the separation of penile skin, subcutaneous tissue, corpus cavernosum and urethral sponge, which are divided into complete type and incomplete type. basic knowledge The proportion of illness: 0.0002% Susceptible people: male Mode of infection: non-infectious Complications: urethral stricture
Cause
Cause of penile injury
The cutting of the penis can be seen in the war, gunshot wounds, mechanical accidents, traffic accidents and injuries, as well as self-harm or castration, which 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 have also occurred. It is reported that American animal bites account for 1% of emergency departments, 60% of which are reported. ~70% are children, dog bites account for the majority, especially the damage of the penis scrotum.
Animal bites may cause avulsion of the penis skin, loss of the penis or combined with urethral injury, which may cause potential harm after injury, resulting in soft tissue damage, infection, urethral stricture and severe sexual function.
Prevention
Penile injury prevention
The disease is caused by trauma directly acting on the penis, such as kicking, falling or riding across the injury. Therefore, pay attention to living habits. High-risk workers, such as construction workers and mining workers, are prone to damage. In the course of work, care should be taken to protect themselves from trauma. Pay attention to calmness and avoid emotional conflicts leading to the disease. Sexual life should be gentle. Secondly, early detection, early diagnosis and early treatment are also important for the prevention of this disease.
Complication
Penile breakage complications Complications urethral stricture
Some complications may occur after re-implantation of the penis. The incidence is from high to low: skin necrosis, urethral stricture, poor penis at the distal end of the penis, urinary leakage, urethra necrosis, impotence, and vascular anastomosis. The incidence of symptoms is significantly lower than that of only the anastomosis of the corpus cavernosum and the urethra. Therefore, it is currently advocated an anastomosis of the anastomosis of the penis.
Symptom
Penile injury symptoms common symptoms penile injury pale pale blood pressure drop limbs cold shock
After the penis is disconnected, the patient has pale blood, the patient's face is pale, the limbs are cold, the blood pressure drops, the shock occurs, the penile stump is obviously bleeding, and it is not easy to stop bleeding. If the distal end is broken or the animal bite, the wound is not neat. The contusion is obvious; the knife cuts and cuts, the wound is neat, and the replanting is easy to survive.
Examine
Penile injury examination
For traumatic fractures, it can be clarified by penile physical examination. A small number of symptoms are not obvious, the diagnosis should be confirmed by cavernography or ultrasound and MRI.
Diagnosis
Diagnosis and diagnosis of penile injury
diagnosis
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 to merge the perineum, the scrotum, Testicular damage and presence or absence of posterior urethra, bladder damage.
Differential diagnosis
Different from the following diseases
1. Penile fibrous cavernositis: may have a history of penile injury, penile pain may occur when erect, but no congestion, bleeding and swelling. The dorsal side of the penis can touch one or several hard masses and cords, such as cartilage, with mild tenderness. There is a filling defect in the lesion at the cavernous angiography.
2. Penile ossification: penile ossification is relatively rare, caused by calcification and fibrosis of the corpus cavernosum, and its nodules often appear as horns. It can cause pain when the penis is erect, and can lead to difficulty in sexual intercourse. X-ray examination showed a shadow with increased density in the penis.
