In the field of urology, phimosis is a relatively common disease. Phimosis generally refers to the fact that the foreskin still covers the glans, but the glans is able to be exposed in the state of erection. The opposite is phimosis, which means that the foreskin covers the glans in an erect state, but the glans cannot be exposed. The phimosis is a more serious condition, and the circumcision should be divided into specific cases before deciding whether to choose surgical treatment. If the circumcision does not lead to obvious clinical symptoms, and does not lead to repeated inflammatory infections, you can temporarily observe and wait, do not need to be treated. If the circumcision has affected the patient’s urination, or led to repeated inflammatory infections, it is best to go to the hospital in time for surgical treatment to cut off the excessively long foreskin.
