Children are phimosis. After puberty, the penis develops and opens, and it can be opened at this time. If urination is affected, there will be a big bag after urination, and surgery must be performed, which will affect development, usually at the age of seven or eight; If after the age of thirteen or fourteen, the penis has developed and the foreskin is still long, it is recommended to have an operation quickly. Zhang Guoxi: The first question that circumcision should answer is, when is the best age for circumcision? In fact, it is controversial and may be related to personal experience. In fact, someone mentioned just now that the Jewish state was born in the State of Israel, so he has no problem. So the problem is, if he is too young to operate, then he needs general anesthesia. Then there is this problem at this time. Of course, if the child is very young, but his foreskin is phimosis, but all children are phimosis, he can't open it. Except after puberty, his penis develops slowly and is open. It may be opened at this time, and his child can't open it before puberty, so if he affects urination at this time. Some people say that there is a big bag bulging after urinating, that is, the urinary layer may need to undergo surgery at this time, whether it is circumcision or something else, because it will affect the development, because what he wants to do, then when do you usually do it? I think what I do can usually be done at the age of seven or eight. At this time, as long as he listens, he can listen if you anesthetize him, but he can't if you don't hold the needle. As long as you are obedient and can be anesthetized, you can have an operation. This is relative. Of course, if you say that after puberty at the age of thirteen or fourteen, then you find that the penis has developed and the foreskin is still very long. I suggest you do it at this time, because he can cooperate and the operation time is short and the speed is fast. Why not do it? Because his foreskin is too long, it has certain influence. Then when it comes to the long foreskin, I think the details of the operation are usually not obvious seasonality, because now, the season we usually talk about is the problem of bathing, because it is usually at least one week after surgery, so it is best not to get water on the foreskin, so you can overcome it in summer, because the patients I receive here are not too seasonal, so it should not have much impact. The best time for children to be circumcised depends on the situation. If the foreskin is too long and leads to repeated balanitis or even urethritis, surgery should be done in time. Under normal circumstances, if children's foreskin can be everted, the exposed glans should be clean and hygienic, just like adults. As long as it can be turned out clean, there is no need for surgery. Ordinary adults can judge that the foreskin is too long and can also diagnose phimosis. But if it is a child, some children are born with physiological phimosis and grow with the glans. But when the child is two or three years old, it will naturally relieve itself, and there will be no phimosis. At this time, congestion can determine whether the child's foreskin is really too long. Therefore, if children need phimosis or foreskin surgery, it will be suggested to judge whether there are phimosis that can be relieved by themselves after the age of three, and whether there are any will affect them.
