Abstract

In renal diagnosis, the B-mode ultrasound is used to provide an accurate study of the renal morphology, whereas thecolour and power Doppler are of strategic importance in providing qualitative and quantitative information aboutthe renal vasculature, which can also be obtained through the assessment of the resistive index (RI). To date, this is one ofthe most sensitive parameters in the study of kidney diseases and allows us to quantify the changes in renal plasma flow. Ifa proper Doppler ultrasound examination is carried out and a critical analysis of the values obtained is performed, the RImeasurement at the interlobar artery level has been suggested in the differential diagnosis between nephropathies. Theaim of this review is to highlight the pathological conditions in which the study of intrarenal RI provides useful informationabout the pathophysiology of renal diseases in both the native and the transplanted kidneys.
