最近2年間の男子尿道炎患者181例を対象に臨床的検討を行った.原因微生物は, 淋菌性尿道炎92例(クラミジアとの混合感染22例), 非淋菌性尿道炎89例(クラミジア52例)であった.年齢分布は, 全体では20歳代, 30歳代, 10歳代後半の順で多く, 淋菌性尿道炎では20歳代後半, 非淋菌性尿道炎では20歳代前半にピークを認め, 10歳代後半では6割以上が非淋菌性尿道炎であった.特定できた感染経路は, 淋菌性尿道炎ではcommercial sex worker39例(オーラルセックス28例), 友人18例, 妻1例, 非淋菌性尿道炎ではCSW12例(オーラルセックス8例), 友人24例, 妻4例であった.治療は淋菌性尿道炎では83例にSPCMが投与され, 判定可能であった55例全例で淋菌消失を認めた.非淋菌性尿道炎ではMINO, キノロン系抗菌剤などが投与され, 判定可能であった66例中58例が治癒したWe studied 181 patients diagnosed with male urethritis at Oogaki Municipal Hospital from April 2002 to March 2004. Twenty-two out of 92 patients diagnosed with gonococcal urethritis (GU) and 52 out of 89 patients diagnosed with non-gonococcal urethritis (NGU) were positive for Chlamidia trichomatis by polymerase chain reaction (PCR). Most patients of male urethritis were in their twenties. Of GU patients, 39 (67%) were infected from commercial sex workers (CSWs).

Elimination rate of Neisseria gonorrhoeae was 100% and 14 out of 18 patients with persisting urethritis had C. trichomatis. Eighty-two NGU patients were treated with minocycline, tosufloxacin, levofloxacin, gatiflixacin or clarithromycine. Sixty-six patients could be evaluated for the efficacy of treatment. Forty-one patients were diagnosed with non-gonococcal chlamydial urethritis (NGCU) and 25 patients were diagnosed with non-gonococcal, non-chlamydial urethritis (NGNCU). The clinical curative rate of NGCU and NGNCU was 93% (38/41) and 80% (20/25), respectively
