Difficulty in turning up the foreskin is commonly seen in patients with circumcision in clinical practice. Circumcision is mainly due to a long foreskin and the presence of a narrow outer foreskin opening. Due to the narrowing of the foreskin, the foreskin cannot be turned over or is difficult to be turned over, so that the glans cannot leak out freely enough. Circumcision can have a certain impact on men’s health, and the presence of circumcision can easily form a large amount of foreskin scale. After the formation of the foreskin scale, it will irritate the mucous membrane of the foreskin and glans, causing inflammation and causing adhesion of the foreskin and glans. In severe cases, it can also affect the erection of the penis, causing pain during erection and affecting men’s sex life. For patients with prepuce, the foreskin should not be forcibly turned up to avoid causing foreskin gentleness, and need to go to urology to perform circumcision for treatment.
