title: Ureteral obstruction secondary to bifurcated aortic grafts.
abstract: We report three cases of ureteral obstruction producing hydronephrosis following aortofemoral bypass graft. In each case, the obstruction occurred in the area where in the ureter crossed over the limb of a Dacron graft. Ureterolysis relieved the obstruction. Most of the previously reported cases of this complication of bypass surgery occurred when the ureter was situated between the limb of a graft and the patient's own iliac artery. Various methods of surgical appraoch are listed. In some cases, ureterolysis is a suitable alternative to division and reanastomosis of the ureter to relieve obstruction.
