Mycobacterial urethritis in men is relatively rare, and is related to many factors such as patients suffering from chronic wasting disease for a long time, abusing broad-spectrum antibiotics, and sexual partners having mycobacterial vaginitis or urethritis. Mycobacterial urethritis in men has milder symptoms compared to gonorrhea, and usually manifests itself as urethral tingling, frequent urination, urgency, painful urination, and dysuria, etc. The urethral opening may have mucous or purulent discharge. The diagnosis is confirmed when mold mycelia and spores are found in the urine and molds are cultivated in the urine. Oral antifungal drugs can be used, or intravenous antifungal drugs can be used, and antibiotics are usually no longer used during treatment. Specific diagnosis and treatment must be carried out under the guidance of a doctor, do not self-medication treatment.
