Tubal imaging in this context refers to tubal imaging. Tubal imaging is usually not recommended for a cleanliness level of 3, which is negative for both mycobacteria and trichomonas. Cleanliness level 3 usually refers to vaginal cleanliness level III. Vaginal cleanliness is usually categorized into four degrees. I/II degree indicates good vaginal cleanliness and a relatively normal environment for vaginal flora; if the vaginal cleanliness is III/IV degree, it indicates a poor vaginal environment, abnormal vaginal flora, and the possibility of vaginal inflammation. When a patient undergoes tubal imaging, the contrast medium is injected into the uterine cavity from the cervix through a contrast tube. At this time, the cervix and vagina are connected, and germs in the vagina will enter the uterine cavity, fallopian tube, pelvis and other parts of the uterine cavity through the cervix, leading to the appearance of infection symptoms. Therefore, it is usually not possible to have a tubal imaging test with a vaginal cleanliness level of III. In case of vaginal cleanliness III degree, it is necessary to follow the doctor’s advice, carry out active treatment, and wait until the vaginal environment improves before carrying out the tubal imaging examination. If the patient’s condition is urgent, then follow the doctor’s instructions and take appropriate treatment measures according to the specific situation.
