[Anuria associated with an aorto-iliac aneurysm. Apropos of a case].

The authors report a case of a perianeurysmal retroperitoneal fibrosis (RPF) with oligoanuric renal failure. A complete assessment was performed with computed tomography. Bilateral ureteral catheterization restored normal renal function and allowed surgical treatment to be performed including an aorto-iliac replacement and a bilateral ureterolysis with intra-peritoneal diversion of the ureter. A review of the literature revealed 15 similar cases. Pathophysiology and treatment of the retroperitoneal peri-aneurysmal fibrosis are discussed.
