The decision of how long to remove the gauze after circumcision depends on the healing of the wound, which will be removed three days after the operation if the wound is healing well, and one week after the operation if the wound is healing poorly. Circumcision refers to the removal of excess foreskin from the penis to expose the head of the penis, and is an effective treatment mainly used to treat phimosis and phimosis in clinical practice. After circumcision, if the wound is healing well and there is no obvious bleeding, edema or infection, the gauze can be removed three days after the operation. After circumcision surgery, if the wound healing is poor, there is intermittent bleeding between wounds, there are obvious symptoms such as edema, it is recommended to remove it one week after the surgery. Care should be taken to sterilize and disinfect the wound with povidone-iodine to prevent symptoms of infection. If the patient wants to undergo circumcision surgery, it is recommended to do so under the guidance of a professional doctor and pay attention to local hygiene after the surgery to prevent wound infection.
