Prostatitis is inflammation or infection of the prostate gland ¡ª an organ about the size and shape of a walnut, located just below the bladder in males. The prostate gland produces semen, the fluid that helps nourish and transport sperm. Prostatitis can cause a variety of symptoms, including a frequent and urgent need to urinate and pain or burning when urinating ¡ª often accompanied by pelvic, groin or low back pain.
Prostatitis has been classified by the National Institutes of Health (NIH) into four categories.
Category 1 is acute bacterial prostatitis.
Category 2 is chronic bacterial prostatitis.
Category 3 includes the conditions previously known as nonbacterial prostatitis, prostatodynia and chronic pelvic pain syndrome.
Category 4 is asymptomatic inflammatory prostatitis.
Pain relievers and several weeks of treatment with antibiotic are typically needed for category 1 and 2 prostatitis, which are bacterial infections. A variety of treatments as well as self-care measures also can provide relief. Treatment for category 3 prostatitis (nonbacterial) is less clear and mainly involves relieving symptoms. Category 4 prostatitis is usually found during examination for another reason and often doesn't require treatment.
