Les valves de l'uretère : à propos de deux observations

Ureteric valves are a rare cause of ureteric obstruction. Fifty cases have been described in the literature. We report two new cases. The first is of a 12-year-old child with left multiple ureteric valves associated to bilateral vesico-ureteric reflux. The patient was treated by uretero-ileoplasty with unfavourable evolution to renal failure. The second case is that of a proximal ureteric valve discovered in a 30-year-old woman who had postpartum acute pyelonephritis. Treatment consisted in ureteric resection–anastomosis with favourable outcome. Based on a review of the literature, we discuss epidemiologic, etiologic, diagnostic and therapeutic aspects of this malformation.
