Should renal resistive index be considered as a routine predictor in newly diagnosed acute hydronephrosis in patients with unilateral renal colic?

Medičnì Perspektivi, 2022
Urinary tract stones are the most common causes of urinary tract obstruction, leading to patient hospitalization in the emergency room. This study is aimed to evaluate the use of the mean resistance index (mRI) to predict hydronephrosis in patients ...

Renal resistive index in hypertensive patients: a one centre study

Arterial Hypertension, 2023
BACKGROUND: Hypertension (HTN) is a leading cause of kidney dysfunction. Renal resistive index (RRI) was an index to evaluate arterial compliance and/or resistance, reflecting the reduction of kidney function and microalbuminuria.

Renal Resistive Index [PDF]

Hypertension, 2014
Of all the measured parameters in nephrology, none is more misunderstood and misused than the renal resistive index ( RI ). Although it is used widely as a marker of renal pathology based on the assumption that structural changes in the kidney alter renal vascular resistance, the sensitivity and specificity of RI for this purpose are questionable,1 and

Dopplerfluxometria das artérias renais: valores normais das velocidades sistólica e diastólica e do índice resistivo nas artérias renais principais Renal arteries Dopplerfluxometry: normal systolic and diastolic flow velocities and resistive index values in the main renal arteries

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2006
Dopplerfluxometry of renal arteries has been used to estimate renal perfusion in humans. The aim of this study was to use Dopplerfluxometry technique to calculate the resistive index of main renal arteries in dogs, measuring their systolic and diastolic ...

Correlation of Duplex Ultrasonographic Parameters with Glomerular Filtration Rate in Chronic Kidney Disease

Journal of Nepal Health Research Council, 2019
Background: Chronic kidney disease encompasses a spectrum of different pathophysiological processes associated with abnormal renal function and a progressive decline in glomerular filtration rate. Duplex ultrasonography is widely available and important

Renal Resistive Index as a Novel Indicator for Renal Complications in High-Fat Diet-Fed Mice

Kidney & Blood Pressure Research, 2017
Background/Aims: The renal resistive index (RI) is a novel candidate as a renal injury prognostic indicator, but it remains unclear how renal RI levels correspond to renal injury in diabetic nephropathy. Methods: To examine this issue, we compared 8-week-

A retrospective study of acute kidney injury in dogs with renal resistive index as a prognostic indicator [PDF]

Journal of Veterinary and Animal Sciences, 2022
Doppler ultrasonography is relatively a new method for evaluation of the renal diseases in dogs. This study was conducted to evaluate the efficacy of renal resistive index (RRI) in diagnosis and prognosis of acute kidney injury (AKI) in dogs and to ...

Renal resistive index in hypertensive patients

The Journal of Clinical Hypertension, 2018
AbstractSpectral Doppler ultrasonography provides the evaluation of renal resistive index (RRI), a noninvasive and reproducible measure to investigate arterial compliance and/or resistance. RRI seems to possess an important role in the evaluation of diverse cases of secondary hypertension.
