We evaluated 236 asymptomatic men for urethritis, assessed sexual behaviors, and tested urine for pathogens. Asymptomatic urethritis was present in 38 (16.1%). Of these, nearly half (42.1%) had a previously unrecognized discharge on examination; only 18.4% had a known pathogen. Correlates included black race, anal intercourse, and number of sex partners.
Urethral inflammation was detected among 16% of asymptomatic men in this study. Behavioral correlates suggest sexually transmitted etiology, yet most patients were tested negative for known sexually transmitted pathogens.
