title: [Bilateral stenosing ureteritis in Henoch-Schnlein purpura].
abstract: BACKGROUND
  Ureteral complications in Henoch-Schonlein's purpura are rare. They may post difficult problems of diagnosis.
  
  
  METHODS
  Bilateral uretal stenosis revealed by low back pain, macroscopic hematuria, leukocyturia and renal failure appeared 15 days after the onset of Henoch-Schönlein purpura in a 14-year-old boy. It was confirmed by ultrasonography; intravenous pyelography showed stenosis of both proximal uretera associated to bilateral hydronephrosis. Treatment with corticosteroids relieved the symptoms and normalized the renal function in restoring patency of both ureters. Nevertheless, the patient was still suffering from mild bilateral hydronephrosis and bilateral renal lithiasis, 2 years later.
  
  
  CONCLUSIONS
  Macroscopic hematuria and renal failure, usually indicative of renal involvement in Henoch-Schönlein syndrome can be the first manifestations of the ureteritis exceptionally seen in this vasculitis.
