Prostatitis is an inflammation of the prostate gland, in men. A prostatitis diagnosis is assigned at 8% of all urologist and 1% of all primary care physician visits in the United States.

Classification

The term prostatitis refers, in its strictest sense, to histological (microscopic) inflammation of the tissue of the prostate gland, although it is loosely (and confusingly) used to describe several completely different conditions. To remedy this, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) devised a new classification system in 1999, comprising four categories of prostatitis:

Category I

Main article: Acute prostatitis

Acute prostatitis is a bacterial infection of the prostate gland that requires urgent medical treatment.

Category II

Main article: Chronic bacterial prostatitis

Chronic bacterial prostatitis is a relatively rare condition that usually presents as intermittent urinary tract infections.

Category III

Main article: Chronic prostatitis/chronic pelvic pain syndrome

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS), accounting for 90%-95% of prostatitis diagnoses, is also known as chronic nonbacterial prostatitis. The annual prevalence in the population of chronic pelvic pain syndrome is 0.5%. Men in this category have no known infection, but do have extensive pelvic pain lasting more than 3 months. There are no standard diagnostic tests; diagnosis is by exclusion of other disease entities. Multimodal therapy is the most successful treatment option,= and includes α-blockers,= phytotherapy, and protocols aimed at quieting the pelvic nerves through myofascial trigger point release with psychological re-training for anxiety control.= Antibiotics are not recommended.=

Category IV

Main article: Asymptomatic inflammatory prostatitis

Asymptomatic inflammatory prostatitis patients have no history of genitourinary pain complaints, but leukocytosis is noted, usually during evaluation for other conditions. Between 6-19% of men have pus cells in their semen but no symptoms.=
