Circumcision can be considered if the age is greater than 5 years old or if it is repeatedly induced by glans phimosis. Since boys are born with congenital phimosis or circumcision, if the pediatric patient is younger than 5 years old and does not have recurrent episodes of glans phimosis, circumcision is generally not recommended, and may improve on its own after the age of 5 years with the gradual development of the reproductive system. The patient is older than 5 years old or repeatedly induced by the foreskin glans dolichitis, after the emergence of this situation, it is recommended to carry out circumcision, the excessive length of the foreskin removal, can reduce the incidence of the foreskin glans dolichitis, but also to avoid the development of the penis is affected. When the patient appears to be circumcised, it is recommended to consult the doctor in time, improve the preoperative examination, actively cooperate with the doctor during the operation, and do a good job in all aspects of postoperative care, which is conducive to recovery.
