Objective: The aim of the present study was to evaluate the incidence of U. urealyticum in women presenting with chronic urinary symptoms at our hospital.

Methods: We studied 153 consecutive women referred to our academic hospital for chronic voiding symptoms who underwent urologic evaluation between January 2007 and March 2008. Patients with UTI were excluded from the study. Only women with no prior cultures or assays for the identification of mycoplasmas were enrolled in the study while subjects receiving antibiotics within the previous month were not included. Samples from the urethra, vagina and cervix were obtained from all women. In order to identify aerobic microorganisms samples were inoculated on blood agar, MacConkey agar, Chapman and Sabouraud agar followed by incubation at 37°C for 24 hours, whereas anaerobic cultures were carried out on Wilkins-Chalgren agar at 37°C for 48 hours. The automated system VITEK 2 (BioMerieux, France) was used for the identification of isolated strains while for the identification of U. urealyticum, the Mycoplasma IST 2 (BioMerieux, Marcy l'Etoile, France).

Results: The median age of the women studied was 51.7 years (range 24–70). U. urealyticum was detected from at least one site in 81 (52.9%) women. In particular, 26 (32.1%) women had positive cultures for U. urealyticum from one site (12 from urethra, 5 from vagina and 9 from cervix) while in 55 (67.9%) women, positive cultures were obtained from all 3 sites. In 27 (17.7%) cases, U. urealyticum was the only pathogen isolated, in 10 (6.5%) patients U. urealyticum was associated with Streptococcus agalactiae, in 10 (6.5%) with Enterococcus faecalis, in 9 (5.9%) with Staphylococcus aureus, in 6 (3.9%) with Pseudomonas aeruginosa, in 3 (2.0%) with Klebsiella pneumoniae, in 10 (6.5%) with Gardnerella vaginalis and 6 (3.9%) with Candida spp. Twenty four (15.7%) women had positive cultures only for Enterococcus faecalis (17) or S. agalactiae (7) while 16 (10.4%) had Gram-negative rods and 5 G. vaginalis. Finally, in 27 (17.7%) patients no pathogens could be isolated.

Conclusions: A high incidence of U. urealyticum was observed in our study group. Therefore, it is important to test all patients with chronic urinary symptoms for the presence of this microorganism.
