Objective: Urethritis is the most frequent sexually transmitted disease symdrom. The aim of this study is to know the prevalence and tendency of microorganisms producing urethritis in primary attendance.

Methods: Cross-sectional study. It is studied the urethral exudate of 1371 patients, 1248 men and 123 women, for 3 years (January 2003–December 2005). The samples were studied for: GRAM stain, culture in habitual plates, Chlamydia trachomatis detection by inmunocromatography method CHLAMY-CHECK-1 (GRIFOLS) and U. urealyticum and M. hominis by Mycoplasma IST2 method (bioMérieux).

Results: The percentage of positive samples was 36.98%. The isolated microorganisms were: N. gonorrhoeae 6.56%, U. urealyticum 13.42%, M. hominis 1.68%, Chlamydia trachomatis 4.45%, H. parainfluenzae 1.90%, H. influenzae 1.17%, E. coli 2.19%, S. agalactiae 1.46%, S. aureus 0.58%, Ec. faecalis 0.29%, K. pneumoniae 0.29%, S.pyogenes 0.22%, Candida sp 1.75% and other 0.73%. Two or more microorganisms were isolated in 3.36%. In women, the percentage of positive samples was 69.11% and 32.69% in men. In 2003 the percentage of positivity was 28.03% and N. gonorrhoeae the most frequent microorganism (5.94%). In 2004 was 40.58% and U. urealyticum the most frequent (16.36%) and in 2005 was 41.76% being U. urealyticum the most frequent (17.34%).

Conclusions: The isolated microorganisms with more frecuency were: U. urealyticum, N. gonorrhoeae and Chlamydia trachomatis. The most frequent association was U. urealyticum + M. hominis. Women had more percentage of positive samples than men. In men, the isolated most frequently microorganisms were: U. urealyticum, N. gonorrhoeae, Chlamydia trachomatis, H. parainfluenzae and E. coli, while in women were: U. urealyticum, M. hominis and Candida sp. The percentage of positive samples were increasing for the years, from 28% in 2003 to 41.76% in 2005.
