We investigated the incidence of male urethritis, including cases caused by Mycoplasma genitalium, which is considered a culprit behind nonchlamydial nongonococcal urethritis. There were 223 patients with urethritis, including 38 with gonococcal urethritis, 96 with chlamydial urethritis, and 89 with nonchlamydial nongonococcal urethritis. A total of 16 patients were tested for M. genitalium, which resulted in 6 positive cases. Nonchlamydial nongonococcal urethritis was detected in 43% of noncommercial sex workers (non-CSWs) and 28% of commercial sex workers (CSWs), showing no significant deviation from the overall trend in urethritis. Considering that M. genitalium testing is frequently performed only in cases where initial urethritis treatment fails, due to insurance coverage limitations, this testing was performed in only 15% of nonchlamydial nongonococcal urethritis cases. To facilitate the initiation of more appropriate treatments for urethritis caused by M. genitalium from the early stages of medical consultation, there is hope for an expansion in insurance coverage that would allow PCR testing right from the first visit.
