À propos de deux cas rares de triplication urétérale

Abstract

Triplication of the upper urinary tract is rare. It is classified according to its extent and four types have been documented. Since the first description of ureteral triplication by Wrany only about a hundred cases have been reported in the literature. Paediatric cases are very few and female patients seem more concerned. The embryological event resulting in ureteral triplication derives from multiple ureteral buds arising from the Wolffian duct with fissuring of one or more of them. We report on two cases of ureteral triplication. The first one associated with an extravesical ectopic ureter and a dysplasic kidney. Diagnosis was particularly difficult and treatment consisted of total nephrectomy. The second case was associated with an upper pole hydronephrosis and a partial nephrectomy was realized.
