Circumcision is usually circumcision and is not mandatory for boys. If a boy has a prepuce, recurrent inflammation of the foreskin and glans, he usually needs circumcision. As long as the boy’s foreskin can be turned up and cleaned with water every day, there is no recurrent inflammation of the glans and the foreskin, in the case of not affecting the quality of life and health, generally do not need to be circumcised. However, if the foreskin can not be turned up to reveal the glans, which is more likely to lead to the accumulation of foreskin scale on the glans, and even cause repeated inflammation of the glans and foreskin, it is recommended to go to a regular hospital to do circumcision. For boys who have the need for circumcision, they need to go to a regular hospital for a comprehensive examination, and then undergo circumcision after the doctor’s evaluation. Post-operative patients should also pay attention to a light diet and increase water intake appropriately in order to maintain a smooth flow of urine.
