Wegener's granulomatosis: A rare cause of hydronephrosis

Abstract

A seventy-one-year-old woman was hospitalized at our institution for a right-sided renal colic associated with an infectious background. Alithiasic ureterohydronephrosis was diagnosed by imaging. A urinary diversion was thus performed using a double J endoureteral stent. The etiologic assessment of the hydronephrosis showed the presence of a periureteral mass that caused extrinsic ureteral compression. After surgical excision of the ureteral lesion, the Wegener's granulomatosis diagnosis was established. This report is the clinical description of a case of atypical Wegener's granulomatosis revealed by the onset of a ureteral disease mimicking a neoplastic process. © Copyright 2011 Julien Lillaz et al.
