RESUMEN
We examined a total of 194 patients over 18 years of age with chronic prostatitis syndrome and no evidence of structural or functional lower genitourinary tract abnormalities. The following data were obtained for each patient: clinical history--the severity of chronic prostatitis symptoms scored by a Croatian translation of the NiH CPSI questionnaire, clinical status including digitorectal examination, urethral swab specimens, and selective samples of urine and expressed prostatic secretion, according to the 4-glass localization test (meares and Stamey localization technique). Patients were treated orally with antimicrobial agents in doses and duration according to clinical practice in Croatia. An infectious etiology was determined in 169 (87%) patients. Chlamydia trachomatis was the causative pathogen in 38 (20%), Trichomonas vaginalis in 35 (18%), Enterococcus in 36 (19%) and Escherichia coli in 35 (18%) patients. In the remaining 25 patients the following causative pathogens were found: Ureaplasma urealyticum, Proteus mirabilis, Klebsiella pneumoniae, Streptococcus agalactiae and Pseudomonas aeruginosa. Comparison of symptoms scores and effect on quality of life has shown that the most severe clinical presentation of disease was recorded in patients with chronic bacterial prostatitis caused by E. coli and Enterococcus (p<0.001). Clinical success was paralleled by bacteriological eradication in chronic bacterial prostatitis caused by C. trachomatis, Enterococcus and E. coli (kappa >0.2<0.5), but not in inflammatory chronic pelvic pain syndrome caused by T. vaginalis.
