[Ureteral lesions produced by an aortofemoral prosthesis. Apropos of a case].

Ureteral lesions following surgery to aorta are reported infrequently. Since 1966, when Lytton published an account of ureteral obstruction from a graft anterior to ureter, several series have been published. In the present case the initial problem was to consider the diagnosis, masked by a supposedly abdominal symptomatology. The second stage was analysis of results of urography and tests of the fluid collection. Effective treatment of this serious complication with preservation of infection of graft was obtained in the case reported by conservative surgery by means of ureteral anastomosis.
