The redness of the glans after stopping the medication for Mycoplasma Urealyticum may be related to recurrence, and requires medical examination of urine culture as well as treatment with medication. Mycoplasma urealyticum infection is commonly found in the genitourinary system and can be transmitted through sexual contact. When Mycoplasma Urealyticum infection occurs, the vulva will be red, swollen, itchy, and abnormal secretions, etc. If the infection recurs after treatment, the above symptoms will also occur, and then we should conduct urine culture and other tests as soon as possible, and use medication, and drug sensitivity tests if necessary. For Mycoplasma urealyticum infection, it is necessary to pay attention to the regular review, and can not be based on the subjective symptoms as a criterion for stopping the drug, but should also refer to the results of laboratory tests. In the course of treatment, it is necessary to review the test several times on time, and the drug can be discontinued only after three or more consecutive negative test results. If the drug is discontinued incorrectly, it is likely that Mycoplasma lysureticum will become resistant to the drug, increasing the difficulty of treatment.
