The usual infecting organisms are aerobic gram-negative bacilli or, less frequently, Staphylococcus aureus.

Symptoms of Prostate Abscess

Common symptoms include

  • Urinary frequency

  • Dysuria

  • Urinary retention

Rectal examination may disclose prostate tenderness and fluctuance, but prostate enlargement is often the only abnormality, and sometimes the gland feels normal.

Diagnosis of Prostate Abscess

  • Prostate ultrasonography and possibly cystoscopy

Many abscesses, however, are discovered unexpectedly during prostate surgery or endoscopy; bulging of a lateral lobe into the prostatic urethra or rupture during instrumentation reveals the abscess. Although pyuria and bacteriuria are common, urine may be normal. Blood cultures are positive in some patients.

Treatment of Prostate Abscess

  • Antibiotics

  • Drainage

Treatment involves appropriate antibiotics plus drainage by transurethral evacuation or transperineal aspiration and drainage. Pending culture results, empiric antibiotic therapy is begun with a fluoroquinolone (eg, ciprofloxacin).
