Complications for symptomatic men include urethritis, prostatitis, epididymitis, and infertility. Causes include infections associated with urethritis, prostatitis, epididymitis, as well as use of anti-depressants. Symptoms experienced include pain, burning or itching in the penis, urethra (urethritis), or vagina (vaginitis). "Trichomonas vaginalis" infection in males has been found to cause asymptomatic urethritis and prostatitis. Reactive arthritis is characterized by nongonococcal urethritis, conjunctivitis, and arthritis. These infections are usually classified as a urethritis rather than urinary tract infection. NGU, sometimes called nonspecific urethritis (NSU), has both infectious and noninfectious causes. Oxytetracycline is especially valuable in treating nonspecific urethritis, Lyme disease, brucellosis, cholera, typhus, tularaemia. These infections are typically classified as a urethritis rather than a urinary tract infection. "U. urealyticum" can cause urethritis and bacterial vaginosis. They can become a source of chronic hematuria, infection, and urethritis. In female patients, urethritis can be caused by pelvic inflammatory disease. Nonspecific urethritis may be treated with a short course of tetracycline. Both are common causes of multiple other conditions including pelvic inflammatory disease and urethritis. This is adenoviral urethritis, and it is classified as a type of non-gonococcal urethritis (NGU).
