title: [Ureteral stenosis in Wegener's granulomatosis. Case report].
abstract: BACKGROUND
  Ureteral stenoses in Wegener's granulomatosis are rare. They usually involve the pelvic portion of the ureter and are caused by vasculitic lesions or granulomatous inflammation.
  
  
  METHODS
  A 38-year-old woman with Wegener's granulomatosis was treated with corticosteroids and monthly intravenous cyclophosphamide pulses. After 4 months, urinary retention developed, accompanied by lumbar pain, associated with protenuria and hematuria, and related to bilateral ureteral stenoses. Treatment by endoscopic dilatation and double J stents led to with clinical and radiological improvement, while the medical treatment continued.
  
  
  CONCLUSIONS
  Hematuria in patients with Wegener's granulomatosis suggests renal involvement, but ureteral stenoses must also be considered when these patients present hematuria or urinary tract infections. Surgery should be reserved for those patients in whom medical treatment is not rapidly effective.
