Prostatitis is an umbrella term for a variety of medical conditions that incorporate bacterial and non-bacterial origin illnesses in the pelvic region. In contrast with the plain meaning of the word (which means "inflammation of the prostate"), the diagnosis may not always include inflammation. Prostatitis is classified into acute, chronic, asymptomatic inflammatory prostatitis, and chronic pelvic pain syndrome.

In the United States, prostatitis is diagnosed in 8% of all male urologist visits and 1% of all primary care physician visits for male genitourinary symptoms.{{cite journal |vauthors=Collins MM, Stafford RS, O'Leary MP, Barry MJ |title=How common is prostatitis? A national survey of physician visits |journal=J. Urol. |volume=159 |issue=4 |pages=1224–8 |year=1998 |pmid=9507840| doi = 10.1016/S0022-5347(01)63564-X}}

Classification

The term prostatitis refers to inflammation of the tissue of the prostate gland. It may occur as an appropriate physiological response to an infection, or it may occur in the absence of infection.{{Cite journal|author-link1=Roger Kirby|last1=Kirby|first1=Roger|author-link2=Culley C. Carson III|last2=Carson|first2=Culley C.|date=January–February 2015|title=Editor's Comment on Diagnosis and treatment of chronic prostatitis/chronic pelvic pain syndrome|journal=Trends in Urology and Men's Health|volume=6|issue=1|pages=17|doi=10.1002/tre.434|doi-access=free}}

In 1999, the National Institutes of Health devised a new classification system.{{cite journal |vauthors=Krieger JN, Nyberg L, Nickel JC |title=NIH consensus definition and classification of prostatitis |journal=JAMA |volume=282 |issue=3 |pages=236–7 |date=July 1999 |pmid=10422990 |doi= 10.1001/jama.282.3.236}}{{cite book|author=J.

| Asymptomatic inflammatory prostatitis

| (none)

| No

| No

| Yes

| style="text-align: left" |No history of genitourinary pain complaints, but leukocytosis is noted, usually during evaluation for other conditions. Between 6 and 19% of men have pus cells in their semen but no symptoms.{{cite journal |vauthors=Korrovits P, Ausmees K, Mändar R, Punab M |title=Prevalence of asymptomatic inflammatory (National Institutes of Health Category IV) prostatitis in young men according to semen analysis |journal=Urology |volume=71 |issue=6 |pages=1010–5 |date=June 2008 |pmid=18455767 |doi=10.1016/j.urology.2007.12.082 }}

In 1968, Meares and Stamey determined a classification technique based on the culturing of bacteria.{{cite journal |vauthors=Meares EM, Stamey TA |title=Bacteriologic localization patterns in bacterial prostatitis and urethritis |journal=Invest Urol |volume=5 |issue=5 |pages=492–518 |date=March 1968 |pmid=4870505 }} This classification is no longer used.

The conditions are distinguished by the different presentation of pain, white blood cells (WBCs) in the urine, duration of symptoms and bacteria cultured from the urine. To help express prostatic secretions that may contain WBCs and bacteria, prostate massage is sometimes used.{{cite web |url=http://www.merckmanuals.com/professional/genitourinary_disorders/benign_prostate_disease/prostatitis.html |title=Prostatitis: Benign Prostate Disease: Merck Manual Professional |access-date=2011-07-11 |archive-date=2011-09-25 |archive-url=https://web.archive.org/web/20110925051318/http://www.merckmanuals.com/professional/genitourinary_disorders/benign_prostate_disease/prostatitis.html |url-status=live }}
