The term<unk>  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. 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<unk> , including information on symptoms, treatment, and prognosis, follow the links to the relevant full articles. Category Current name Old name Pain Bacteria WBCs Description I Acute<unk>  Acute bacterial<unk>  Yes Yes Yes Bacterial infection of the prostate gland that requires urgent medical treatment. II Chronic bacterial<unk>  Chronic bacterial<unk>  ± Yes Yes A relatively rare condition that usually presents as intermittent urinary tract infections. IIIa Inflammatory CP/CPPS Nonbacterial<unk>  Yes No Yes Accounts for 90–95% of<unk>  diagnoses, formerly known as chronic nonbacterial<unk> '. IIIb Noninflammatory CP/CPPS Prostatodynia Yes No No IV Asymptomatic inflammatory<unk>  (none) No No Yes 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. In 1968, Meares and Stamey determined a classification technique based upon the culturing of bacteria. 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.
