It is generally assumed that renal blood flow is symmetric in the absence of renal artery stenosis. The importance of studying the function of both kidneys separately is because it cannot be assumed that they are functionally equal.The aim of the present study is to evaluate whether this is really in patients with essential hypertension and/or moderate kidneys loss.

Condition Intervention
