[Ureteral multiplicity: report of 3 cases]

The ureteric multiplicity is a rare malformation with about one hundred cases described in the literature. The rarity of this anomaly and the complexity of possible associated anomalies often make the preoperative diagnosis difficult. The authors report 1 case of partial quadruplicate ureter associated with bladder duplication and 2 cases of triplicate ureter, corresponding to types I, II and III of Smith's classification. Based on their experience and a review of the literature, they discuss the diagnostic approach and treatment of these anomalies.
