[Late urological complications of reconstructive surgery of the aortic bifurcation (author's transl)].

Ureteral obstruction following aorto-iliac or aorto-femoral dacron prosthesis has rarely been described. It seems, however, as shown in our three cases, that this complication is more common than was previously believed. In all three cases, ureteral obstruction was attributed to retroperitoneal fibrosis enclosing the graft. The threat of such a complication should lead the surgeon to carry out intravenous urography in all patients with a vascular prosthesis.
