Ureteropelvic junction obstruction of the upper pole moiety is reported in 2 patients with complete ureteral duplication. A normal upper pole ureter of a duplicated system in conjunction with upper pole dilatation should alert the urologist to the presence of an upper pole ureteropelvic junction obstruction. Traditional pyeloplasty techniques can be applied to this anomaly with successful salvage of renal parenchyma. The embryological implications of this combination of anomalies occurring in a single patient are discussed briefly.
