Contrast-enhanced voiding urosonography (CEVUS) with dual screen mode. The right kidney is duplex and is simultaneously demonstrated in (a) greyscale mode and (b) contrast-only mode during bladder filling. Echogenic contrast is seen filling the upper and lower moieties (arrows) of the right kidney retrogradely. There is significant dilation of the renal pelvis and blunting of the renal calyces. These findings are in keeping with grade 3 reflux. (Image courtesy of Dr. Susan Back, Philidelphia, PA, USA)
