title: Xanthogranulomatous pyelonephritis in children: conservative management.
abstract: OBJECTIVE
  Three new cases of xanthogranulomatous pyelonephritis are described in children.
  
  
  METHODS
  Laboratory examinations including white and red blood cell counts, erythrocyte sedimentation rate, renal function, urinalysis and cystography were performed.
  
  
  RESULTS
  All of the patients had a palpable abdominal mass. Urine culture was positive (Proteus mirabilis) in only 1 patient. Associated urological abnormalities were found in 2 cases. Urographically a functionless kidney was encountered in 2 children and a renal mass in the other. None could be diagnosed preoperatively.
  
  
  CONCLUSIONS
  Although nephrectomy has been said to be the treatment of choice, conservative treatment can be successful as shown by 1 of our patients.
