title: Ultrasound-guided needle aspiration in prostatic abscess.
abstract: OBJECTIVE
  To review the clinical presentation of prostatic abscess and to assess the usefulness of ultrasound-guided needle aspiration as a treatment option for this condition.
  
  
  METHODS
  Between October 1984 and November 1997, prostatic abscess was diagnosed in 31 patients. The average age was 60 years (range 29 to 79). Prostate ultrasound was performed using either a hypogastric or transrectal approach. Initial therapy included ultrasound-guided needle aspiration in 24 (77.4%), transurethral resection of prostate (TURP) in 5 (16.1%), or conservative management with antibiotic therapy. During follow-up, ultrasound examinations and urine cultures were performed on an outpatient basis.
  
  
  RESULTS
  Past medical history most often included previous urinary infection (15 patients, 48%) and bladder outlet obstruction (13 patients, 42%). Sixty-one percent of patients presented with irritative voiding symptoms at the time of diagnosis. Ultrasound-guided needle aspiration resolved 83.3% of cases; 2 patients needed a second procedure. Three patients required TURP for drainage and 2 to remove an obstruction after abscess resolution.
  
  
  CONCLUSIONS
  A high degree of suspicion is needed to diagnose prostatic abscess clinically. Transrectal ultrasound is necessary for the differential diagnosis. Transrectal ultrasound-guided needle aspiration is a technically simple and effective therapeutic procedure with no morbidity and, in case of failure, may be repeated or a drainage TURP may be undertaken.
