Inflammation of the prostate (prostatitis)

There are various types of prostatitis. The different types are distinguished on the basis of their pattern of occurrence and cause:

  • acute or chronic
  • bacterial or abacterial

This condition is the most common urological disorder diagnosed in men under 50, and about 10% of men will develop prostatitis at some point in their lives.

Prostatitis is commonly classified using the National Institute of Health classification system:

  • Category I: Acute bacterial prostatitis
    ➔ This is an acute infection of the prostate.
  • Category II: Chronic bacterial prostatitis
    ➔ This is inflammation of the prostate as a result of repeated infections over a period of at least 3 months.
    → 5% of chronic prostatitis is bacterial in origin.
  • Category III: Chronic abacterial prostatitis/chronic pelvic pain syndrome (CPPS)
    → No bacteria can be detected.
    → 95% of chronic prostatitis falls into this category.

    Category III is divided into the following sub-categories:

    • Category III a: Evidence of inflammation can be detected in prostatic secretions.
    • Category III b: No evidence of inflammation can be detected in prostatic secretions.
  • Category IV: Asymptomatic inflammatory prostatitis
    → The patient has no symptoms, but a prostate biopsy or analysis of prostatic secretions shows evidence of inflammation.
