Wegener's Granulomatosis : A Rare Cause of Hydronephrosis

Abstract EN

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.
