Since clinical presentation varies widely and diferential diag- nosis includes life threating conditions, CP is often overlooked. Moreover, despite having negative impact on patients’ quality of life, CP receives a somehow little attention in clinical practice in comparison with other urological conditions. In this paper we present clinical patterns of chronic prostatitis recorded in 1624 visits aiming to determine the incidence of NIH categories of chronic prostatitis among patients referring to a single Hellenic tertiary care center with symptoms of prostatitis and to describe the clinical characteristics of chronic prostatitis on our population. MATERIAL: The clinical sample used in the study consisted of medical records of individuals with reported pelvic discomfort, genital pain, lower urinary tract symptoms and sexual dysfunc- tion, and from patients with febrile relapses of chronic bacte- rial prostatitis, visiting the Urology Department of the Tzaneio Prefecture General Hospital of Piraeus, between 03/2009 and 03/2019. Patients with febrile prostatitis were evaluated with a single mid-stream "clean" urine sample culture while in all remaining cases, the Meares and Stamey test –or the two glass test– was performed. Bacterial identifcation was per formed using the Vitek 2 Compact system and the sensitivity test was performed with the disc and the Vitek 2 system. Demographic, microbiological and clinical history of each assessed patient were reviewed.
