European Society of Hypertension/European Society of Cardiology guidelines recommend calculation of estimated glomerular filtration rate and evaluation of urinary albumin excretion rate as routine tests in the initial evaluation and during the follow-up of all hypertensive patients. However, from a clinical point of view, renal ultrasound – a noninvasive, readily available and cheap imaging modality – could contribute to the better evaluation of a hypertensive patient by identifying common causes of secondary hypertension (HTN) originating from the kidney and more recently by detecting renal injury in severe or long-standing essential HTN by measuring renal resistive indexes. The purpose of this review is to summarize the actual evidence which could support a larger use of renal ultrasound in the work-up of patients with newly diagnosed HTN.
