Chronic Bacterial Prostatitis Treatment

Diagnostic Confirmation

  • The European Association of Urology recommends performing the Meares and Stamey 2- or 4-glass test to confirm chronic bacterial prostatitis and identify E. faecalis as the causative organism 1, 2
  • Culture specimens should be taken to determine antimicrobial susceptibility patterns, which is crucial for guiding targeted therapy 2
  • The European Association of Urology guidelines advise against relying solely on ejaculate analysis for diagnosis 2

Treatment Recommendation

  • The European Association of Urology supports the use of fluoroquinolones, such as levofloxacin, for the treatment of chronic bacterial prostatitis 1, 2
  • Ampicillin-based regimens, such as ampicillin 200 mg/kg/day IV in 4-6 doses, can be considered for fluoroquinolone-resistant strains, with the option to add gentamicin for synergistic effect in severe cases 3, 4
  • Transrectal ultrasound can be performed in selected cases to rule out prostatic abscess, which would require additional intervention 2
