ABSTRACT

To investigate the category 2 frequency and microorganism distribution of patients diagnosed with chronic prostatitis in a Turkish population.

Data of 3200 patients diagnosed with chronic prostatitis in the urology outpatient clinic between 2009 and 2014 were retrospectively reviewed. The symptom scores were calculated considering the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) according to pain (0-21 points), quality of life (0-12 points), and urinary (0-10 points) subdomains to a total score of 0-43 points. All patients were checked for symptoms, urinalysis, expressed prostatic secretion (EPS), or urine after prostatic massage (VB3) culture and PCR (Polymerase Chain Reaction) of EPS or VB3 for Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Mycoplasma genitalium, and Trichomonas vaginalis.

The mean age of the patients was calculated as 37.7±7.4 (range 22-65) years. The average of total NIH-CPSI score was determined as 9.08 (range 1-40). In 223 of 3200 patients, positive culture and/or PCR results were observed. The results were as follows: E. coli 27 (12.1%), E. faecalis 18 (8.1%), S. epidermidis 15 (6.7%), S. haemolyticus 10 (4.5%), S. aureus 5 (2.2%), S. agalactiae 4 (1.8%), Pseudomonas 3 (1.3%), C. trachomatis 24 (10.8%), U. urealyticum 95 (42.6%), M. genitalium 6 (2.7%), M. hominis 14 (6.3%), and T. vaginalis 2 (0.9%).

In a Turkish population, category 2 patients constitute 7% of all chronic prostatitis patients. This ratio is consistent with the NIH classification of prostatitis data, but it differs etiologically with U. urealyticum, E. coli, and C. trachomatis being the most proliferated pathogens in our study.
