Broken penis

Introduction to penile fracture Penile fracture refers to the penis in an erect state, and the external violence causes the rupture of the corpus cavernosum. The normal thickness of the corpus cavernosum is about 2mm. When the penis is erect, the vascular sinus is congested, the internal pressure is increased, and the white film is thinned only 0.2-0.25mm, which is prone to rupture. The rupture is often horizontal, generally not more than 1/2 of the circumference of the sponge, and most of them are located at 1/3. This kind of damage is rare, because it is difficult to say, so many cases have not been reported. basic knowledge The proportion of illness: 0.06% Susceptible people: male Mode of infection: non-infectious Complications: urethral injury, sexual dysfunction

Cause of penile fracture

Vertical external force (45%):

Penile fracture often occurs when the penis is erect, such as sexual intercourse caused the penis to hit the woman's pubic symphysis or perineum, or masturbation to break the penis and cause injury, according to domestic statistics, these two reasons are 45% and 38%, respectively. The erect penis squeezed in the bed about 10%, and the other 7% belonged to the other.

Pathogenesis

The penis is ruptured by the direct external force in the erectile state, and the tunica albuginea is one of the intimate fascia in the body. However, the blood flow of the penis in the erectile state increases by 7 to 8 times, and the white film is stretched and thinned ( It is 1/8~1/4 of the time when it is erectile. It loses its elasticity. At this time, it is extremely susceptible to vertical external force, and even a slight external force causes the white film and the sponge to rupture.

Penile break 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. It should be gentle in sexual life. Secondly, early detection, early diagnosis and early treatment are also important for the prevention of this disease.

Penile fracture complications Complications, urethral injury, dysfunction

Penile fracture conservative treatment complications up to 30% to 44%, including missed diagnosis of urethral injury, persistent hematoma, secondary infection, penile fibrosis and angular deformity, painful nodules, and resulting sexual dysfunction, early choice Patients with surgical treatment have no such complications.

Penile fracture symptoms common symptoms severe pain, ecchymosis, penile injury

The patient usually complains that during the sexual intercourse, the penis is twisted, there is a sound when it breaks, accompanied by severe pain, and then the penile erection subsides, the penis becomes soft, swollen, bent and deformed to the healthy side, due to rupture of the cavernous and tunica albuginea, The formation of hematoma and ecchymosis, the skin of the penis is blue-purple, and there is no abnormality in urination.

Penile fracture examination

For a few symptoms that are not obvious, the diagnosis should be confirmed by cavernography or ultrasound and MRI. In the diagnosis, it is necessary to identify whether one or both sides of the cavernous rupture, whether there is urethral injury, whether it is simple skin injury, vascular injury, penis Transposition and so on. MRI is also the magnetic resonance imaging. The full name of English is: nuclear magnetic resonance imaging. The reason why it was not called nuclear magnetic resonance and later called magnetic resonance is because Japanese scientists have proposed that their country is under nuclear weapons. To show respect, they will remove the nuclear word. It is.

Diagnosis and identification of penile fracture

Diagnostic criteria

1. There is a history of local penile injury.

2. Local pain in the penis after injury, congestion, bleeding, swelling can be seen.

3. When the penile fracture often occurs in the erectile state, there is often a loud sound and severe pain at the moment of injury. At this time, the erect penis is also soft.

Differential diagnosis

Penile fibrous cavernitis, may have a history of penile injury, penile pain may occur when erect, but no congestion, bleeding and swelling, the back of the penis may touch one or several hard masses and cords, such as cartilage There is mild tenderness, and there is a filling defect in the lesion at the cavernous angiography.
