| 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.<ref name="pmid8234704">{{cite journal| author=Kliewer MA, Tupler RH, Carroll BA, Paine SS, Kriegshauser JS, Hertzberg BS et al.| title=Renal artery stenosis: analysis of Doppler waveform parameters and tardus-parvus pattern. | journal=Radiology | year= 1993 | volume= 189 | issue= 3 | pages= 779-87 | pmid=8234704 | doi=10.1148/radiology.189.3.8234704 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=8234704 }} </ref><ref name="pmid2243982">{{cite journal| author=Desberg AL, Paushter DM, Lammert GK, Hale JC, Troy RB, Novick AC et al.| title=Renal artery stenosis: evaluation with color Doppler flow imaging. | journal=Radiology | year= 1990 | volume= 177 | issue= 3 | pages= 749-53 | pmid=2243982 | doi=10.1148/radiology.177.3.2243982 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=2243982 }} </ref>

| 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%.<ref name="pmid21719621">{{cite journal| author=Lao D, Parasher PS, Cho KC, Yeghiazarians Y| title=Atherosclerotic renal artery stenosis--diagnosis and treatment. | journal=Mayo Clin Proc | year= 2011 | volume= 86 | issue= 7 | pages= 649-57 |pmid=21719621 | doi=10.4065/mcp.2011.0181 | pmc=PMC3127560 |url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21719621 }} </ref>

| 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).<ref name="pmid15114537">{{cite journal| author=Kidney Disease Outcomes Quality Initiative (K/DOQI)| title=K/DOQI clinical practice guidelines on hypertension and antihypertensive agents in chronic kidney disease. | journal=Am J Kidney Dis | year= 2004 | volume= 43 | issue= 5 Suppl 1 | pages= S1-290 | pmid=15114537 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=15114537 }} </ref>
