Table 2 Practical ultrasound features in differentiating acute vs chronic glomerulonephritis1
| Parameter | Acute GN/AKI | Chronic GN/CKD | Key differentiating feature |
| Kidney size | Normal or enlarged | Decreased renal length | Enlarged = acute; small = chronic |
| Cortical thickness | May be normal or increased | Reduced | Thinning indicates chronic damage |
| Echogenicity | Increased (infiltrates/edema) | Increased (fibrosis/sclerosis) | Alone non-specific; paired with size aids differential diagnosis |
| Corticomedullary differentiation | May be increased, Preserved or increased | Often reduced or lost | Loss of differentiation implies chronicity |
