Table 1: Vesicoureteral reflux grades according to the international reflux study committee.
GRADES |
ANATOMICAL LEVEL AND AFFECTED STRUCTURES |
I |
Reflux is limited to the ureter (no ureter dilation) |
II |
Reflux fills the ureter, renal pelvis and collecting system (no dilation) |
III |
Reflux fills the ureter, renal pelvis and collecting system (Mild ureteral and pelvicalyceal dilation) |
IV |
Reflux fills the ureter, renal pelvis and collecting system (Gross ureteral dilation with mild tortuosity and calyceal blunting) |
V |
Reflux fills the ureter, renal pelvis and collecting system (Severe ureteral dilation and tortuosity, severe calyceal blunting, loss of papillary impressions and fornices, intrarenal reflux) |
