Ureteral Obstruction as a Complication in Aorto-Iliac Reconstructive Surgery

Abstract

Two cases of ureteral obstruction secondary to aorto-iliac reconstruction with bifurcation aortic grafts are described. Twenty-eight cases have been called from the literature and analysed. There seem to exist two types of aetiology regarding this complication: development of heavy localized fibrosis, and mechanical compression owing to the ureter having been placed behind the graft. Symptoms are often diffuse, but after operative treatment the prognosis seems good. The actual incidence of this complication is not known.
