Types of Prostatitis

There are four types of prostatitis: acute bacterial prostatitis, chronic bacterial prostatitis, nonbacterial prostatitis, and prostatodynia.

Acute bacterial prostatitis (ABP) is inflammation of the prostate gland caused by bacteria such as Escherichia coli and Klebsiella. Severe complications may develop if not promptly treated. ABP can be fatal if the bacterial infection is untreated and travels to the bloodstream (sepsis).

Chronic bacterial prostatitis (CBP) is a recurrent infection and inflammation of the prostate and urinary tract. Symptoms are less severe than those associated with acute bacterial prostatitis. Increasing numbers of men are being diagnosed with interstitial cystitis who had been previously misdiagnosed with chronic prostatitis.

Nonbacterial prostatitis is an inflamed prostate without bacterial infection.

Prostatodynia, sometimes called chronic pelvic pain syndrome (CPPS), is the occurrence of prostatitis symptoms, without inflammation or bacterial infection.
