Prostatitis is an inflammation of the prostate gland. A prostatitis diagnosis is assigned at eight percent of all urologist and one percent of all primary care physician visits in the United States. The term prostatitis refers, in its strictest sense, to histological (microscopic) inflammation of the tissue of the prostate gland. Like all forms of inflammation, it can be associated with an appropriate response of the body to an infection, but it also occurs in the absence of infection. in 1999, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) devised a new classification system. For more specifics about each type of prostatitis, including information on symptoms, treatment, and prognosis, follow the links to the relevant full articles. In 1968, Meares and Stamey determined a classification technique based upon the culturing of bacteria. This classification is no longer used.
