Editor's Notes

• #9: For decades, urologists have classified prostatitis into types using the Meares-Stamey system. This system identifies four prostatitis varieties based on systemic symptoms, localizing cultures of urine and prostatic fluid, and leukocytosis in expressed prostatic secretions (EPS). Beginning in 1994, the NIH began supporting a new classification system based primarily on the presenting clinical syndrome (Table 1). Category I prostatitis is acute prostatitis with acute systemic manifestations and concomitant urinary tract infection (UTI). Category II prostatitis is chronic bacterial prostatitis, with recurrent urinary tract infection or other symptoms associated with a uropathogenic infection, as detected in EPS or semen. Category III prostatitis replaces the terms “nonbacterial prostatitis” and “prostatodynia” with the more purely descriptive “chronic pelvic pain syndrome” (CPPS). Type IIIa disease, unlike Type IIIb, is associated with leukocytosis in the EPS, although the appropriate technique for EPS-leukocyte assessment and the correct cut-off point is a matter of some debate. Finally, type IV prostatitis refers to asymptomatic patients who are found to have prostatic inflammation, typically by prostatic biopsy for an elevated serum prostate-specific antigen (PSA) or leukospermia during an infertility evaluation.
