Causes of urethritis include chemical irritation, chronic pelvic pain syndrome, epididymitis, genital herpes, mucositis, prostatitis, trauma, and UTI. The only bacteria not mentioned in your list is Ureaplasma urealyticum. Treatment should have been initiated prior to the results being reported; that's the standard. The urine test can be repeated, especially if it was not a first-void urine sample
