Wegener's Granulomatosis Presenting as a Ureteral Obstruction / 대한신장학회잡지

ABSTRACT

In Wegener's granulomatosis, the classical clinical picture is composed of a triad of symptoms sinusitis-rhinitis, pulmonary lesion and glomerulonephritis with granulomatous lesions and necrotizing vasculitis of involved organs. But localization in retroperitoneal tissue is unusual. In this case, hydronephrosis and ureteral obstruction is the sole presenting symptoms of the disease. At exploratory laparotomy, the right ureter was found to be obstructed by dense, extrinsic fibroinflammatory reaction. There was a necrotizing granulomatous vasculitis in the muscle layer of the ureter.
