Overview
Renal artery stenosis should be differentiated from essential hypertension and other causes of secondary hypertension.
Differentiating [Disease name] from other Diseases
[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
OR
[Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].
OR
As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].
Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]
On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].

Differentiating Renal Artery Stenosis from Essential Hypertension
Hypertensive patients afflicted with renal artery stenosis often have one or more of the following characteristics:
- Onset of hypertension before the age of 30 years
- Onset of severe hypertension (SBP ≥180 mm Hg and/or DBP ≥120 mm Hg) after the age of 55 years
- New azotemia or worsening renal function after administration of an ACE inhibitor or ARB agent
- Unexplained atrophic kidney or size discrepancy between kidneys of greater than 1.5 cm
- Sudden, unexplained pulmonary edema
- Accelerated hypertension (sudden and persistent worsening of previously controlled hypertension)
- Resistant hypertension (failure to achieve goal blood pressure in patients who are adhering to full doses of an appropriate 3-drug regimen that includes a diuretic)
- Malignant hypertension (hypertension with coexistent evidence of acute end-organ damage, i.e., acute renal failure, acutely decompensated congestive heart failure, new visual or neurological disturbance, and/or advanced [grade III to IV] retinopathy)
- Unexplained renal failure in the absence of proteinuria or an abnormal urine sediment
- Multivessel coronary artery disease
- Unexplained congestive heart failure
- Refractory angina
Noninvasive diagnostic studies such as Duplex ultrasound, CT angiography, or magnetic resonance angiography are indicated in the presence of any above-mentioned conditions. If the results of noninvasive screening are inconclusive, catheter angiography may be considered.[1][2]
