Yo-yo reflux or uretero-ureteral reflux is noted in partial ureteral duplication ^1,2. It is the reflux of urine from the normal caliber ureter to the dilated ureter.

Radiographic features

Yo-yo reflux should be suspected when there is asymmetric dilatation of ureters. It can be diagnosed with color Doppler ultrasonography but radionuclide renography has been suggested as an ideal test ⁶.
