A prospective observational study of chronic prostatitis with emphasis on epidemiological and microbiological...

Despite the progress made in recent years in understanding and diagnosing chronic prostatitis (CP) many cases are still underdiagnosed and undertreated for unknown reasons. The purpose of this study is to investigate the epidemiological data of patients with symptoms of CP and to associate data from medical history and clinical examination with the results of laboratory tests.

The study population consisted of individuals with reported pelvic discomfort and genital pain with or without lower urinary tract symptoms and sexual dysfunction visiting our department from 03/2009 to 03/2011. Patients underwent Meares-Stamey test (a few cases underwent the two-glass test). Depending on history and specific symptoms, urethral smear and sperm cultures were additionally obtained from several patients. The processes and reading of the samples were performed by a specialist microbiologist, who has not notified the patient record.

114 out of 155 patients who finally enrolled into the study had a medical history, 69 had sexual behavior and 72 sexual habits that predispose to chronic prostatitis. The clinical examination was not diagnostic in 43.8% of cases. The urethral smear and sperm culture diagnosed coexistent urethral infection in 22 cases. 54 out of the 72 positive EPS/VB3/PPM cultures grew one, 11 two to three and 5 cultures grew more than three different organisms.

Findings of this study debate some widely accepted considerations on the etiology and diagnosis of chronic prostatitis and highlight the uncertainties and controversies regarding chronic prostatitis etiology, pathophysiology, presentation and diagnosis.
