VUR grading

Vesicoureteric reflux (VUR) grading divides vesicoureteric reflux 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  

It is important to note that each side may have a different grade of reflux.
