Renal artery stenosis may be classified according to whether there is unilateral or bilateral involvement of the renal arteries. Additionally, renal artery stenosis is often classified according to severity of luminal narrowing.

Classification

Renal artery stenosis may be classified according to whether there is unilateral or bilateral involvement of the renal arteries. Additionally, renal artery stenosis is often classified anatomically according to severity of luminal narrowing. The following criteria are used according to most published studies about ARAS.[1][2]

Severity Luminal Narrowing
Normal 0%
Mild 1-49%
Moderate 50-69%
Severe 70-99%
Occluded 100%

To note, some studies have different classification criteria than those listed above, with "mild disease" starting after 50% of luminal narrowing. Such classification remains coherent with the definition of ARAS as narrowing > 50%.[3]

Another classification is based on hemodynamic function in RAS. This classification simply differentiates between hemodynamically insignificant RAS (< 75% stenosis) and hemodynamically significant RAS (> 75% stenosis).[4]
