Hydronephrosis in Infants - SFU grading - Society of Fetal Urology
Hydronephrosis in infants is divided into five grades that were standardized by the Society of Fetal Urology. The grading is usually based on ultrasound, ev. intravenous urography.
| Grade | Description |
|---|---|
| Grade 0 | no splitting of renal sinus |
| Grade I | urine visible in renal pelvis only |
| Grade II | urine fills intrarenal pelvis, extrarenal pelvis, major calyces are dilated |
| Grade III | Grade II + minor calyces are uniformly dilated without thinning of parenchyma |
| Grade IV | Grade III + thinning of parenchyma |
