Alternative Names

Definition of Prostatitis – nonbacterial – chronic

Chronic nonbacterial prostatitis is long-term pain and urinary symptoms that involve the prostate gland or other parts of a man’s lower urinary tract or genital area. This condition is not caused by bacterial infection.

Causes, incidence, and risk factors

Possible risk factors for nonbacterial prostatitis include:

Signs and tests

A physical examination usually will not show anything unusual. However, the prostate may be swollen, soft or firm, warm, and tender.


Treatment for nonbacterial prostatitis is difficult. The goal is to control symptoms, because a cure is difficult to achieve.

Expectations (prognosis)

Many patients respond to treatment. However, others do not get relief even after many attempts at treatment. Symptoms often come back after treatment, and may eventually not be treatable.
