Separation of foreskin adhesions is the most common method of preventing penile head foreskin infection. The normal boy penis head foreskin adhesions are separated at the age of 4, but some children will be later, if there is no penis head infection or urinary tract infection, it is not necessary to flip the foreskin, if there is indeed recurrent infection of the penis head foreskin, the inner plate of the foreskin can be separated from the penis head adhesions, the separation should be gentle, not too eager to retreat the foreskin up, when the penis head is exposed, the foreskin should be restored, otherwise it will cause embedded prepuce. If the foreskin adhesions are difficult to separate, corticosteroids, such as Eloson, can be applied daily to the penile foreskin to promote separation. Most children can significantly control the occurrence of penile head circumcision by applying the above methods, and only a small number of children need to be treated by circumcision.
