What should I do if my little brother is injured?

　　The severity of penile trauma varies with the direction and magnitude of the external force. The main common symptoms include pain, swelling, hematuria, urination disorder, etc.

　　1. Penile contusion

　　For example, a worker accidentally fell on an iron tool while working, and his sacrococcyx was hit, resulting in severe pain in the perineum. The penis erection has not been weak for two weeks since the next day, and the root of the penis is sore and accompanied by low back pain , confirmed by examination to be penile contusion complicated by hematoma and priapism.

　　2. Penile dislocation injury

　　The penis is twisted when erect, or is subject to blunt force blows, excessive pulling, or straddling injuries when it is weak, causing the penis to detach from its skin , dislocated to the root of the thigh or the scrotum and perineum. During treatment, in addition to hemostasis and manual reduction, sutures must be used to fix the penis in its normal position.

　　3. Penile impaction injury

　　Mostly due to curiosity, abnormal sexual desire and eccentricities, metal rings, plastic bands, or even large nuts are put on the penis and are not removed in time, or the foreskin of the penis is not reset in time after being turned up, causing blood circulation disorder at the end of the constriction and limited venous return, so edema occurs. In severe cases, the arterial blood supply is even blocked and tissue necrosis occurs. The key to treatment is to remove the strangulated objects as soon as possible (such as sawing off metal rings, nuts, etc.), or to surgically remove the foreskin incarceration. Foreskin that is too long and too tight can also cause incarceration during sexual intercourse, so you should seek medical attention promptly.

　　Injuries can also occur when subjected to direct force such as external blows or straddling, and often occur at the same time as urethral injuries. Moreover, the types of manifestations are complex, and the methods of processing are also different, which are sometimes difficult. The key is to pay attention to your own safety in production and life to prevent unexpected events from happening.
