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.[1]
Classification
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 (which could potentially be treated with antibiotics), but it can also occur in the absence of infection.
in 1999, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) devised a new classification system.[2][3]
| Category | Pain? | Bacteria? | WBCs? | NIDDK (Current) |
Description | Meares/Stamey (Old) |
|---|---|---|---|---|---|---|
| I | yes | yes | yes | Acute prostatitis | Acute prostatitis is a bacterial infection of the prostate gland that requires urgent medical treatment. | Acute bacterial prostatitis |
| II | ± | yes | yes | Chronic bacterial prostatitis | Chronic bacterial prostatitis is a relatively rare condition that usually presents as intermittent urinary tract infections. | Chronic bacterial prostatitis |
| IIIa | yes | no | yes | Inflammatory CP/CPPS | Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS), accounting for 90%-95% of prostatitis diagnoses,[4] used to be known as chronic nonbacterial prostatitis. | Nonbacterial prostatitis |
| IIIb | yes | no | no | Noninflammatory CP/CPPS | Prostatodynia | |
| IV | no | no | yes | 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.[5] | (none) |
In 1968, Meares and Stamey determined a classification technique based upon the culturing of bacteria.[6] This classification is no longer used.
The conditions are distinguished by the different presentation of pain, 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.[7]
