Diagnosis and Management of Chronic Bacterial Prostatitis or Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS)

Clinical Presentation and Diagnosis

• The American Urological Association identifies that CP/CPPS characteristically causes pain at the tip of the penis, perineum, suprapubic region, or testicles, with pain often exacerbated by urination 1, 2
• Burning with urination and nocturia are core features of both chronic bacterial prostatitis and CP/CPPS, with the American Urological Association noting that nocturia and urinary urgency are common symptoms of CP/CPPS 1, 2
• The presence of fever suggests bacterial prostatitis, and the European Association of Urology recommends taking midstream urine culture in patients with acute bacterial prostatitis symptoms to guide diagnosis, with accurate microbiological evaluation for atypical pathogens such as Chlamydia trachomatis and Mycoplasma species being crucial in chronic bacterial prostatitis 3

Diagnostic Steps and Alternative Diagnoses

• The European Association of Urology suggests performing blood cultures and complete blood count given the fever, as well as midstream urine culture to guide antibiotic treatment, and testing for atypical pathogens via nucleic acid amplification test on first-void urine 3, 1
• The Meares and Stamey 2- or 4-glass test should be considered if chronic bacterial prostatitis is confirmed after acute phase resolves 3
• Fournier's Gangrene and appendicitis must be urgently excluded, with the World Society of Emergency Surgery guidelines describing Fournier's Gangrene as necrotizing fasciitis with perineal/genital pain that can radiate to the abdomen, fever, and systemic features, and the ACR Appropriateness Criteria noting that right lower quadrant pain with fever could represent appendicitis 4, 5, 7, 8

Management and Treatment

• Empiric antibiotic therapy should be initiated immediately, with the European Association of Urology suggesting fluoroquinolones (levofloxacin or ciprofloxacin) for a minimum of 4 weeks as first-line therapy for chronic bacterial prostatitis, and considering parenteral therapy if severe infection is present 3
• If sexually transmitted infection is suspected, consider adding coverage for Chlamydia and Gonorrhea with ceftriaxone 1000 mg IM/IV plus doxycycline 3, 1

Common Pitfalls and Considerations

• Prostatic infections may not show in midstream urine, and prostatic massage is contraindicated in acute bacterial prostatitis due to bacteremia risk 3, 1
• The American Urological Association notes that CP/CPPS and interstitial cystitis/bladder pain syndrome have overlapping presentations, and some patients meet criteria for both conditions, and if symptoms persist despite antibiotic therapy, consider this overlap 1, 2
