Epidemiology and demographics of prostatitis.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a multifactorial problem affecting men of all ages and demographics. Currently, there is a relative dearth of epidemiological information on CPPS. It is clear that patients with CPPS have a dismal quality of life and many have benefited only minimally from empiric, goal-directed therapy. Long-term follow-up of the CPPS cohort will answer important questions about the natural and treated history of this syndrome. Similarly, ongoing and future studies will provide community-based and prevalence estimates for CPPS, morbidity rates for men with CPPS, and the rates of symptom improvement and symptom deterioration for these men, as well as the probability of benefits and harm from different treatments. Although men with CP routinely receive anti-inflammatory and antimicrobial therapy, recent studies suggest that leucocyte and bacterial counts do not correlate with severity of symptoms. These findings suggest that factors other than leucocytes and bacteria contribute to the symptoms associated with CPPS. The probability of benefits and harm from different treatments for CPPS, and reliable and valid measures to define these outcomes are eagerly awaited.
