Prostatitis & CPPS
"Prostatitis" is mostly not a bacterial infection — the great majority of men labelled with it have chronic pelvic pain syndrome (CPPS), where cultures are negative and the problem is pain, not bugs.
The big picture
"Prostatitis" is mostly not a bacterial infection — the great majority of men labelled with it have chronic pelvic pain syndrome (CPPS), where cultures are negative and the problem is pain, not bugs. The clinically vital task is to use the NIH classification to separate the genuinely bacterial categories (which need antibiotics) from CPPS (which does not), so you don't keep throwing antibiotics at a non-infective syndrome.
The framework: the NIH categories I–IV → localise infection (cultures) → treat the bacterial categories with prolonged prostate-penetrating antibiotics, and manage CPPS multimodally.

Board traps
Most "prostatitis" is CPPS (Category III), not infection — don't treat it with endless antibiotics.
NIH: I acute bacterial, II chronic bacterial, III CP/CPPS (IIIA inflammatory / IIIB non-inflammatory), IV asymptomatic inflammatory.
Category II (CBP) is the cause of relapsing same-organism male UTIs — localise and treat long.
Bacterial prostatitis needs prolonged (4–6 wk), prostate-penetrating antibiotics — fluoroquinolone is the agent of choice.
In ABP avoid vigorous prostate massage (bacteraemia); drain an abscess.
CPPS → UPOINT-directed multimodal therapy.
