scrotal injury
Introduction
Introduction to scrotal injury Scrotal injury is more common in gunshot wounds and sharp injuries in wartime, bruises on sports grounds or industrial and agricultural labor, and kicks and scratches during play, fight, and sometimes due to improper operation of the scrotal surgery. Types of injuries include: contusions, sharp injuries, livestock bites, skin avulsions, burns, etc. basic knowledge The proportion of illness: 0.002% - 0.007% Susceptible people: male Mode of infection: non-infectious Complications: sepsis
Cause
Cause of scrotal injury
(1) Causes of the disease
1. Closed injuries include scrotal contusion, scrotal hematoma, etc. The injury factors are kick injury, cross injury, crush injury, etc., which occur mostly during normal exercise and heavy physical labor.
2. Open injuries include lacerations, avulsions, penetrating injuries and gunshot wounds, etc., mostly in industrial and mining labor, war wounds or animal bites.
(two) pathogenesis
The scrotum and its contents are close to the body surface and are susceptible to damage, including physical (mechanical external force, heat, low temperature, radiation, etc.), chemical (strong acid, strong alkali, yellow phosphorus, corrosive solvent or gas, etc.) and biological (bacteria, viruses, parasites, insects, animals, etc.) damage, but the location of the scrotum is relatively concealed, and the scrotum is soft and elastic, and its contents have a certain amount of room for movement, so they are subject to injury. It is not very large. Among the many injury factors mentioned above, tissue trauma caused by mechanical external force is more common, and the injury is complicated. Due to the abundant blood supply to the scrotum, there are a large number of small blood vessels and tissue in the scrotum between the skin and the subcutaneous fibrous membrane. Loose, so after the injury, the skin of the person is bruised. In severe cases, the blood vessels are ruptured to form a hematoma or blood cyst. The blood in the early hematoma is red and gradually turns dark red. At this time, there may be a sense of fluctuation, the blood gradually becomes thicker, and the sense of fluctuation disappears. And the formation of a hard block, due to the hard block compression spermatic cord or testicular blood supply is affected, causing testicular atrophy.
Prevention
Scrotal injury prevention
Prevention is mainly to avoid trauma. Early detection, early diagnosis, and early treatment are also important for preventing this disease.
Complication
Scrotal injury complications Complications sepsis
Scrotal injury is usually caused by traumatic factors directly affecting the integrity of the scrotum caused by the scrotum tissue, the testicles in the scrotum can be damaged, and severe testicular damage can cause sperm formation disorders and infertility. Because the disease is a traumatic disease, clinically, it often causes complications such as suppuration and infection of the wound. In severe cases, the infection can enter the blood circulation and cause sepsis.
Symptom
Scrotal injury symptoms common symptoms open injury ecchymosis scrotum swelling shock
The main symptoms of scrotal injury are bleeding and pain, such as no injury to the testicles and no shock.
Examine
Scrotal injury examination
B-ultrasound, CT examination can help to understand the damage of the contents of the scrotum, especially for testicular and epididymal damage.
Diagnosis
Diagnosis and differentiation of scrotal injury
diagnosis
It is not difficult to determine the diagnosis of scrotal injury. The diagnosis is based on:
1 history of scrotal trauma;
2 scrotal swelling, pain, surface skin has ecchymosis, hematoma in the scrotum, open scrotal skin avulsion, testicular exposure;
3 light transmission test was negative.
Pay attention to the diagnosis of scrotal injury:
1 Whether the scrotal injury combined with other injuries, such as penile injury, testicular injury, testicular torsion, spermatic cord injury, etc.;
2 range of scrotal hematoma;
3 Whether there are foreign objects in the scrotum.
Differential diagnosis
1. Idiopathic scrotum gangrene
Can be caused by trauma to the scrotum, but also scrotal swelling, skin purple fever, local obvious pain and other symptoms, but scrotal gangrene often accompanied by chills, high fever, general weakness, and even phlegm and other symptoms of systemic toxicity, check the scrotum skin wet, necrotic The substance has a sensation of sensation, and the scrotal skin necrosis is aggravated within 1 to 2 days, which may affect the testicular sheath and cause the testicular spermatic cord to be exposed. The bacterial culture of the wound can detect hemolytic streptococcus, Staphylococcus aureus, etc. Pathogens.
2. Injurious orchitis
There is a history of scrotal trauma and surgery, there may be swelling of the affected side of the scrotum, pain, but the swelling of the scrotum skin is not obvious, the color has no obvious change, the examination found that the affected side of the testicular swelling, hard, uneven surface, tenderness, and epididymis Sometimes it is not clear that the spermatic cord can be thickened.
3. Hydrocele
Scrotal traumatic scrotal hematoma, hemorrhage, must be identified with hydrocele, the same cystic mass in the scrotum, testis, epididymis is not easy to touch, but hydrocele is more than no trauma and surgical history, light transmission The test was positive.
