Vesicoureteric reflux (VUR) grading divides vesicoureteric reflux (VUR) according to the height of reflux up the ureters and degree of dilatation of the ureters:
grade 1: reflux limited to the ureter
grade 2: reflux up to the renal pelvis
grade 3: mild dilatation of ureter and pelvicalyceal system
-
grade 4
tortuous ureter with moderate dilatation
blunting of fornices but preserved papillary impressions
-
grade 5
tortuous ureter with severe dilatation of ureter and pelvicalyceal system
loss of fornices and papillary impressions 2
It is important to note that each side may have a different grade of reflux.
