The histological scoring system of kidney injury.

Feature	Score	Description
Interstitial fibrosis	0	Normal interstitium and tubules
	1	Mild interstitial thickening between the tubules
	2	Moderate interstitial thickening between the tubules
	3	Severe interstitial thickening between the tubules
Tubular injury	0	No tubular injury
	1	<10% of tubules injured
	2	10%~25% of tubules injured
	3	26%~50% of tubules injured
	4	51%~75% of tubules injured
	5	>75% of tubules injured

Tubular injury was defined as tubular dilation, tubular atrophy, vacuolization, sloughing of tubular epithelial cells, or thickening of the tubular basement membrane.
