Complications of circumcision mainly include wound bleeding, infection or wound cracking. 1. If the vascular ligation is not complete or the bandage is not tight during circumcision, it will lead to postoperative bleeding of the wound, which must be promptly consulted for re-stopping or bandaging of the wound. 2. If the local inflammation is not effectively controlled before the circumcision or if the urine is contaminated after the operation, the wound may be infected with inflammation, pain and other symptoms, which should be treated with anti-inflammatory and anti-inflammatory treatment in a timely manner. 3. If the wound is not tightly sutured during circumcision, or if the wound is cracked due to strenuous exercise after the operation, bleeding or pain may occur; timely follow-up for re-suturing and bandaging of the wound is required. If circumcision is needed, it is recommended that the patient consults a regular medical institution to reduce the probability of the above risks.
