People with UTIs do not always have an odor when they urinate during an inflammatory infection. The discharge from the urethra of a person with a UTI also does not always have a noticeable odor. Infections that will have a noticeable odor are usually fungal infections or anaerobic infections. So if the UTI is caused by common bacteria or chlamydia or mycoplasma, the urination and urethral discharge does not usually have an odor. Whereas, if the UTI is caused by an anaerobic infection or fungal infection, the urine or urethral discharge may have an odor. The treatment of urethritis should also be based on the different types of pathogens infected, select the appropriate anti-infective drugs, for example, if the anaerobic infection is caused by anaerobic bacteria, the use of metronidazole, tinidazole and other anti-anaerobic bacteria drugs treatment. If it is a fungal infection caused by urethritis, to choose fluconazole, voriconazole and other drugs for treatment.
