It is recommended not to operate blindly on your own, but to go to a regular hospital urology department for treatment in a timely manner. If there is a narrow foreskin opening or a long foreskin, it is generally difficult to make the glans exposed for a long time through foreskin ectropion and set the shape. Patients need to undergo circumcision, otherwise foreskin imbrication will occur, leading to foreskin redness and swelling. If it is a non-inflammatory circumcision, the patient only needs to turn the foreskin up and clean it frequently, no surgery is needed. If the patient has long term prepuce, a large amount of foreskin scale may lead to the risk of penile cancer in the glans of foreskin. Therefore, patients should pay attention to it and seek medical treatment in time if necessary.
