All young boys have foreskin adhesions after birth, around 4 years old the adhesions are gradually absorbed and the foreskin can be turned up freely, some children do not absorb or do not absorb completely, combined with prepuce cysts. If the foreskin adhesions are not completely absorbed or combined with foreskin cysts can cause foreskin inflammation, and some children form inflammatory prepuce. If your child has foreskin adhesions or foreskin cysts, you can perform “foreskin separation”, outpatient treatment, and turn the foreskin up every day for a week after surgery, making sure to turn it to the coronal sulcus and apply erythromycin ointment or polymyxin ointment evenly to isolate the foreskin and glans to avoid re-adhesions (this is very important, do not do in place ze adhesions recur). If it is an inflammatory prepuce then surgery is required. The surgical method can be circumcision or circumcision depending on the condition. Circumcision is suitable for children with mild inflammation or overcircumcision, and is characterized by being done on arrival, no hospitalization, no infusion, and low cost. If the inflammation of the foreskin is severe then circumcision is required and some children need to be hospitalized.
