Nongonococcal urethritis (NGU) frequently occurs in men after infection of the lower genital tract with a genital pathogen and is mostly associate with complaint of a scanty, thin discharge and urinary symptoms. Management of NGU includes clinical examination, microbiological diagnosis of genital pathogens, and efficient treatment as well as contact tracing. Diagnosis, especially of the Chlamydia trachomatis, the most frequent cause of NGU, has improved by using amplification assays for the detection of DNA or rRNA. These new methods have the advantage of a higher sensitivity especially for specimens with a low number of infectious agents. In addition, they enable the use of urine as a noninvasive specimen type.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001437	Bacteriuria	The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.	Bacteriurias
D012335	RNA, Ribosomal	The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome.

D012680	Sensitivity and Specificity	Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)	Specificity,Sensitivity,Specificity and Sensitivity
