Urethritis can be cured basically after about 7-10 days of intravenous drug infusion. However, you need to choose sensitive antibiotics for treatment. In principle, it is best to conduct a culture of secretion or urine culture test to clarify the pathogenic bacteria of the infection, and conduct a drug sensitivity test check to choose the most sensitive antibiotics for treatment, which will cure soon. If the drug is used empirically and resistant drugs are chosen, the symptoms will not be relieved and the time of treatment will be prolonged. Patients who generally do not have culture, if the symptoms do not improve for more than 3 consecutive days with medication, they need to be examined in hospital and the medication should be adjusted for treatment. If the patient’s symptoms improve quickly after medication, the medication should not be stopped blindly. It is necessary to stop the medication until the patient’s symptoms disappear completely and the urine routine or secretion culture is rechecked and completely restored to normal. In principle, the treatment needs to maintain a course of medication, that is, to maintain the amount of about 7 days, basically can achieve the purpose of complete cure. However, in some severe cases, it may be necessary to extend to about 10 days to fully achieve the state of recovery.
