Semiquantitative criteria for renal and hepatic lesions.

Degree	Kidney lesions					Liver lesions
	Glomerulosclerosis	Interstitial fibrosis	Arteriolosclerosis	Interstitial inflammation	Tubular dilatation	Portal inflammation
0	Normal	≤5% renal cortex	No or little intimal incrassation	No or little inflammation	No dilatation	None
1	≤25% mesangial expansion/sclerosis	6∼25% renal cortex	Intimal incrassation leads to lumen stenosis ≤15%	10%∼25% renal cortex	≤25% renal cortex tubule	Mild, some/all portal areas
2	25%∼50% mesangial expansion/sclerosis	26%∼50% renal cortex	Increased intimal incrassation leads to lumen stenosis ≤25%	26%∼50% renal cortex	26∼50% renal cortex tubule	Moderate, some or all portal areas
3	≥50% mesangial expansion/sclerosis	>50% renal cortex	Severe intimal incrassation leads to lumen stenosis ≥50%	>50% renal cortex	≥50% renal cortex tubule	Moderate/marked, all portal area
