As to whether or not occult penis needs to be treated and when it should be treated, it should be said that the timing of surgery depends on the severity of the child’s prepuce, whether or not it is accompanied by symptoms such as prepuce infection, and the parents’ knowledge of occult penis and surgery. If the degree of prepuce is serious and the child is urinating with a bulging foreskin, a skewed urine line, or repeated foreskin infections, surgery can be performed at a young age (I personally believe that surgery can be performed at the earliest at the age of about 1 year old to facilitate the development of the child’s penis and to reduce the psychological impact later on). In fact, if the occult penis is non-circumcised (foreskin can be turned up), surgery is not needed. This type of occult penis is mainly caused by local fat accumulation, and as the penis develops, the occult appearance can be improved. Those that require surgery are actually occult prepuce, a type that has a potential risk of affecting penile development because the foreskin cannot be turned up. The purpose of surgery is mainly to solve the foreskin and improve the conditions of penile development, except that because of the short appearance of the penis at the same time, if circumcision or ringing surgery alone may still cause penile appearance problems, or even in some children not operated by a pediatric urologist, too much foreskin is removed, which affects penile growth instead, therefore, occult penis surgery is performed along with circumcision to solve the foreskin and improve penile appearance Therefore, occult penis surgery should be performed to address the prepuce and improve the penile appearance. This type of surgery is recommended to be performed by an experienced pediatric urologist.
