Ureteral stenosis as the sole manifestation of Wegener's granulomatosis.
In Wegener's granulomatosis, necrotizing lesions are typically located in the upper and lower respiratory tract and kidneys, and ureteral involvement is uncommon. We report 2 cases in which intrinsic ureteral stenosis was the sole manifestation of this small-vessel vasculitis. Excisional surgery evidenced characteristic granulomatous inflammation that allowed adjuvant elective medical treatment. Urologists, nephrologists, and internists should be aware of this atypical presentation of Wegener's granulomatosis. Thorough clinical and biologic assessments are warranted in the initial workup of isolated intrinsic ureteral stenosis.
