Children with chronic kidney disease (CKD) have progressively deteriorating renal function as they move through CKD stages 1 to 5, ultimately requiring hemodialysis or peritoneal dialysis to manage end stage renal disease (1,2).
The KDOQI guidelines define stages of chronic kidney disease based on estimated glomerular filtration rate (GFR) (2):
| Stage | GFR (ml/minute/1.73m2) |
| 1 – kidney damage with normal or high GFR | ≥90 |
| 2 – kidney damage with mild decrease in GFR | 60 - 89 |
| 3 – |
