Obstruction of the ureter due to a false aneurysm.

A false aneurysm arising from an aortofemoral bifurcation graft caused symptomatic ureteral obstruction in a 69-year-old woman. Following revision of the aortograft anastomosis, her symptoms and ureteral obstruction subsided. The prevention and treatment of ureteral complications following vascular surgery are discussed. Postoperative pyelograms may be indicated in the vascular bypass patient.
