Summary
Partial ureteral duplication in an inverted Y is evidenced by the presence of a ureter duplicated at a variable level before reaching the bladder, in either an orthotopic or an ectopic position. A case of ureteral duplication at the level of the renal hilum with opening of a ureter at the level of the epididymis is reported. The description of this original case is compared with the data in the literature. The stages of organogenesis of the superior excretory pathway leading to ureteral ectopia and ureteral anomalies of number are reviewed.
Résumé
La duplication urétérale partielle en Y inversé se traduit par la présence d'un uretère se dédoublant à une hauteur variable avant d'atteindre la vessie, de façon orthotopique ou ectopique. Un cas de dédoublement urétéral au niveau du hile du rein avec abouchement d'un uretère ectopique au niveau de l'épididyme est rapporté. La description de ce cas original permet sa confrontation aux données de la littérature. Les étapes de l'organogenèse de la voie excrétrice supérieure aboutissant aux ectopies urétérales et aux anomalies urétérales de nombre sont rappelées.
