Post-circumcision edema is due to edema caused by exudation, which is generally more common after surgery, and the recovery time of edema is related to the patient’s age and the way the surgery was performed. Minimally invasive circumcision is generally for the following cases. First, children are able to absorb the edema on their own in about a week because the penile blood vessels are relatively thin and fill with blood more slowly, while not easily erected. Second, adolescents are more active, the blood vessels are relatively thicker than children, and with partial sexual impulses, the edema is absorbed relatively slowly, usually in about ten days. Thirdly, adults need about two weeks to recover from edema due to sexual impulses, while blood circulation is strong and erectile congestion aggravates edema. In addition, the recovery time of edema after traditional surgery is extended by about 5-7 days on the basis of these three.
