During 1985 the author studied 477 men with clinical and laboratory evidence of urethritis; 49 (10.3%) were diagnosed as gonococcal urethritis while 428 (89.7%) had the nongonococcal form; these findings agree with those from previous series; the fact that the patients were included irrespectively of the history of previous antimicrobial therapy suggests that a proportion of the nongonococcal cases could be of the postgonococcal modality.
