GPAtlas🧭 When to suspect
Suspect chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) in a man with persistent or recurrent pelvic pain – perineal, testicular, penile, suprapubic, or low back – present for at least 3 of the last 6 months, often accompanied by lower urinary tract symptoms (frequency, urgency, dysuria) or sexual dysfunction (painful ejaculation, erectile dysfunction). It is fundamentally a diagnosis of exclusion: infection (UTI/STI), bladder pathology, and cancer must be excluded first.
The single most useful distinction in primary care is between the rare bacterial and the common non-bacterial cause. Chronic bacterial prostatitis is culture-positive, presents with recurrent urinary infections caused by the same organism, and genuinely responds to a prolonged course of antibiotics. CP/CPPS is non-bacterial and accounts for over 90% of chronic prostatitis – here the evidence for antibiotics is weak, and management is multimodal. The European terminology is moving towards “primary prostate pain syndrome” to reflect that the prostate is often not the source of the problem.
| NIH category | Type | Defining feature |
|---|---|---|
| I | Acute bacterial prostatitis | Acute UTI, systemically unwell – needs prompt antibiotics |
| II | Chronic bacterial prostatitis | Recurrent same-organism UTIs; responds to a prolonged antibiotic course |
| III | CP/CPPS (IIIa inflammatory, IIIb non-inflammatory) | > 90% of cases; pelvic pain ≥ 3 of the last 6 months, no proven infection |
| IV | Asymptomatic inflammatory prostatitis | Incidental (e.g. on biopsy or semen analysis); no symptoms, no treatment |
The key primary-care skills are therefore threefold: exclude red-flag pathology (above all, prostate cancer), separate the treatable bacterial cause from the common non-bacterial syndrome, and adopt phenotype-directed, multimodal management rather than reaching repeatedly for antibiotics.
