RESUMO
Ureteric valves are a rare cause of upper urinary tract obstruction. The authors report 3 cases of ureteric valves: one discovered incidentally during assessment of abdominal trauma and two cases detected by antenatal ultrasound. The diagnosis of ureteric valves was suggested by urography in two cases and was confirmed by immediate preoperative retrograde ureteropyelography in all three cases. The three patients were treated by ureteric resection-anastomosis with a favourable outcome in each case. Based on a review of the literature, the authors discuss the diagnostic modalities and management of ureteric valves. They also discuss the embryological hypotheses concerning the formation of ureteric valves.

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.
