After circumcision surgery, you need to use gauze dressing to stop bleeding and to promote local lymphatic reflux so as to reduce post-operative bleeding and edema of the foreskin, and you can remove the gauze dressing about 5-7 days after surgery. The prerequisite is that there is no obvious bleeding from the surgical incision, no obvious edema from the circumcision, and no obvious local discharge. For poor healing of the incision with dehiscence, it is recommended to continue using the gauze dressing, which can protect the incision and prevent the occurrence of infection.
