UAA-AAUS guideline for M. genitalium and non-chlamydial non-gonococcal urethritis.

Non-chlamydial non-gonococcal urethritis (NCNGU) is defined as urethritis with neither Neisseria gonorrhoeae nor Chlamydia trachomatis. Possible causative agents of NCNGU include Mycoplasma genitalium, Ureaplasma urealyticum, Ureaplasma parvum, Mycoplasma hominis, Trichomonas vaginalis, and so on. Among these microorganisms, the pathogenicity of M. genitalium and T. vaginalis to the male urethra has been confirmed so far. The Asian Association of Urinary Tract Infection and Sexually Transmitted Infection (AAUS) belonging to the Urological Association of Asia (UAA) had developed the guidelines regarding NCNGU and the present guidelines were updated from previous edition. Relevant references were meticulously reviewed again and latest studies were collected. In addition to the levels of evidence, the recommendation grades were defined using the modified GRADE methodology. Herein, we present the new edition of the UAA-AAUS guidelines for M. genitalium and non-chlamydial non-gonococcal urethritis.
