Avoid prostate massage in acute prostatitis

Can precipitate bacteremia / sepsis.

Pearls

  • Boggy, tender prostate on DRE — but limit DRE in acute setting.
  • E. coli > 80% of cases; treat 4-6 weeks (fluoroquinolone or TMP-SMX).
  • Chronic bacterial prostatitis — different entity, requires longer therapy and may need imaging.
