Obstructive uropathy caused by retroperitoneal fibrosis secondary to an aneurysm of the abdominal aorta

Inflammatory abdominal aortic aneurysms are known to be associated with retroperitoneal fibrosis and ureteral complications. We report a case of an inflammatory aneurysm that produced bilateral ureteral envelopment and obstructive renal failure. Incidence, pathogenesis and clinical onset of this kind of aneurysms and management of the ureteral complications are reviewed.
