The scrotal laceration should be thoroughly debrided, and the inactivated tissue and foreign body should be removed before primary repair. If there are many skin defects in the scrotum, which can not completely cover the testis, the testis can be temporarily buried under the skin of the inner thigh in the second stage of scrotum plastic surgery until the testis returns to the scrotum. 2. Closed scrotal injury, (1) scrotal contusion: the scrotum should be raised in bed for 48 hours, then the congestion should be absorbed as soon as possible with hot compress, and antibiotics should be given to prevent infection.
