[Ureteral risk of aorto-iliac surgery. Apropos of a case report of bilateral lesion of the ureters].

The authors report a case of bilateral uretero-hydronephrosis following aorto-bifemoral prosthesis for termino-aortic aneurysm due, on one side, to stenosis of incorrect repair of an operative injury to the ureter and, on the other side, to a syndrome of ureteric compression due to its retroprosthetic course, which is the central feature of this aetiological, pathophysiological and therapeutic discussion. Although the objective of treatment is to preserve the kidney, the risk of treatment is dominated by the threat to the future of the vascular prosthesis. The usual technical problem can be summarised by the question: should one cut the ureter or the prosthesis? and it would appear that a urinary problem does not necessarily imply a urological solution.
