Grades are as follows:
- Grade 1: Reflux only into the non-dilated ureter.
- Grade 2: Reflux into the ureter and the renal pelvis without dilatation
- Grade 3: Reflux with mildly dilated ureter and pyelocalyceal system
- Grade 4: Reflux with the tortuous and moderately dilated ureter with blunting of renal fornices. The papillary impression is preserved
- Grade 5: Reflux with the tortuous and severely dilated ureter, dilatation of pyelocalyces with loss of fornices, and papillary impression
