Abstract
Wegener's granulomatosis (WG) is a multisystem disorder of unknown origin characterized by necrotizing granulomatous vasculitis. WG usually affects the upper respiratory tract, lungs, and kidneys with focal glomeulonephritis, but almost any organ
can be
affected. The ureter is primarilly an unusal location for lesions of WG. A 30-year-old woman presented with intermittent right flank pain and hematuria. A renal ultrasound demonstrated unilateral hydronephrosis and a retrograde pyelography
revealed
a
filling defect at right mid ureter and a computed tomography displayed marked concentric thickening of the right ureteral wall which was mimickig ureteral tumor. At nephroureterectomy, the right ureter was found to be obstructed be dense,
intramural
fibroinflammatory reaction. There was a necrotizing granulomatous vasculitis in the muscle layer of the ureter. Out case represents the rare occurrence of WG presenting ureteral obstruction.
