title: Renal abscess: recovery without hospitalization and drainage.
abstract: BACKGROUND
  Renal absceeses in childhood are rare and require hospitalization, antibiotic therapy and drainage.
  
  
  METHODS
  Two cases of renal abscess in childhood are described. In both cases there was no history of either antecedent skin infection or urinary tract infection or reflux. Flank pain and fever had a sudden onset.
  
  
  RESULTS
  The diagnosis was made in the first case by ultrasound and gadolinium-enhnaced magnetic resonance, in the second case ultrasound and computerized axial tomography were used. The patients were successfully treated at home with antibiotic therapy but without drainage.
  
  
  CONCLUSIONS
  Renal abscesses must be suspected in children with loin pain, fever and leukocytosis. They may heal even without  hospitalization and drainage.
