The most common cause of purulent leucorrhea is local inflammation of the cervix. Gynecological examination often reveals local inflammatory reactions such as congestion and edema of the cervix, and a large amount of purulent discharge will appear locally, and contact bleeding may occur on the surface of the cervix. It is recommended to give active anti-inflammatory treatment and to take cervical canal secretions for bacterial culture and drug sensitivity test, so as to provide a reliable clinical basis for treatment. In this case, it is also recommended to exclude the possibility of gonococcal infection, and if necessary, laboratory tests should be done to exclude the possibility of this disease.
