LASPINA, F et al. Etiological aspects o male infectious urethritis in patients attending laboratories of Asuncion. Mem. Inst. Investig. Cienc. Salud [online]. 2010, vol.8, n.1, pp.41-46. ISSN 1812-9528.

ABSTRACT This study was carried out in order to contribute to the knowledge of the etiological agents of male urethritis in Asunción. It is based on a retrospective review of clinical records of 619 patients from one public and three private laboratories in Asunción. The age mean ± SD was 37.6 ± 15.2 years (range 0-91 years); 373 patients were from Meyer Lab, 166 from San Roque Laboratory, 68 from Santa Clara Laboratory and twelve from the Laboratory of Microbiology of the IICS. Urine samples from 289 patients, urethra secretion from 326 and both types of samples from 4 patients were studied. Diagnosis of Neisseria gonorrhoeae was requestedfor 295 patients, Chlamydia trachomatis for 256, Ureaplasma urealyticum for264, Mycoplasma hominis for 199. Presence of N. gonorrhoeae was demonstrated in 6.4% of the cases, C. trachomatis in 3.5%, U. urealyticum in 11.5% and M. hominis in 2.5%. Even though there was a clear predominance of non-gonococcal urethritis, considering the limitation of this study due to its retrospective nature, prospective studies with larger samples are necessary to establish with certainty the prevalence of the etiological agents of male infectious urethritis, including the search of other infectious agents. It is also necessary to have data about urethritis in other socioeconomic groups and investigate aspects such as the frequency of post-gonococcal urethritis syndrome (PGU) and beta-lactamase producing N. Gonorrhoeaestrains in our area.

Keywords : Infectious urethritis; gonococcal, non-gonococcal; male; Neisseria gonorrhoeae; Chlamydia trachomatis; Ureaplasma urealyticum; Mycoplasma hominis.
