If the foreskin covers all of the head of the penis and the opening of the urethra, but the foreskin can still be turned up so that the head of the penis can be exposed, it can be judged as phimosis.
The foreskin is a common problem in urology, and is determined by the fact that the foreskin covers all of the head of the penis and the urethral opening, but the foreskin can still be turned up so that the head of the penis can be exposed; if the foreskin can not be turned up so that the head of the penis can not be exposed, then it is called phimosis.
When the foreskin is too long, sebaceous gland secretion and epithelial tissue shedding after the formation of foreskin scale is easy to gather under the foreskin, resulting in infection, causing inflammation. If the inflammation is severe an inflammatory adhesion occurs, there is a possibility that secondary phimosis may form, causing difficulty in urination and so on.
If the foreskin can be easily turned up, the circumcision may not be operated. If the opening of the foreskin is small and difficult to turn up, circumcision can be performed.
