Spontaneous ureteric ruptures is a rare condition [1]and bilateral ureteric rupture is even more uncommon. Few cases are described in the literature in which bilateral ureteric rupture is associated to dermatomyositis [2]or to intra-arterial contrast medium application for infrarenal aortic stent placement [3]. We discuss here a case of bilateral ureteric rupture in a 74-year-old man with bladder cancer, presenting oliguric acute kidney failure and a light abdominal pain.
