Urethritis
Urethritis is the inflammation of the urethra (the tube that carries urine from the bladder to the outside of the body), and can be caused by infectious and non-infectious conditions. It is sometimes a symptom of a sexually transmitted infection, such as chlamydia, gonorrhea, or Mycoplasma genitalium, especially in males. People with urethritis may or may not experience symptoms.
Medical tests can determine the cause of urethritis and determine the appropriate treatment. When laboratory testing eliminates gonorrhea as the cause, the diagnosis is nongonococcal urethritis, or NGU. NGU can be treated with antibiotics. Sex partners should also be evaluated and treated to prevent reinfection.
