title: Incidence of ureteral obstruction after aortic grafting: a prospective analysis.
abstract: In this prospective analysis of the incidence of ureteral obstruction after aortic bifurcation grafting, 120 patients were entered into the study: 19 were subsequently excluded for cause, and 101 patients were studied by isotope renography. The renographic findings were indicative for subsequent intravenous pyelography, which was performed in 26 patients. In two cases supplementary retrograde pyelograms were done. Two patients (2%) had ureteral obstruction related to the vascular prosthesis, and in one of these patients the process was bilateral. The lesions were asymptomatic in both patients.
