Ureteric duplication is one of the most common malformations of the urinary tract, affecting 1 in 125 children (0.8%). The combination of routine prenatal ultrasound and improving sonographic technology has resulted in increased detection of organ anomalies, and urologic abnormalities are among the most commonly reported findings. Ureteral duplication may be associated with ectopia or ureterocele, as well as corresponding vesicoureteral reflux (VUR) or hydronephrosis, but it is also compatible with a normally functioning collecting system in cases of partial duplication or when both ureters enter the bladder in an orthotopic location.
