Edema from circumcision is usually able to subside in 1-2 weeks. Edema after circumcision is a relatively common phenomenon, and most patients are likely to have edema after surgery. An edema is not the same as a hematoma, which is easier to get rid of, while a hematoma is usually due to heavy bleeding that pools under the skin. Hematomas are more difficult to remove or to reduce, and if they occur after circumcision, it is possible that 2 surgeries may be needed to remove the hematoma. If the edema is simply present, it is relatively mild. The lymphatic and blood circulation of the foreskin is relatively rich, and it is possible for edema to occur after surgery that blocks both types of circulation. If the edema of the foreskin is more obvious, it is recommended that you can use magnesium sulfate to apply wet compresses, or use hypertonic saline into wet compresses. In addition, you can also use potassium permanganate solution to soak, which is conducive to the subsidence of edema.
