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 obese and non‑obese cats

Veterinaria Italiana, 2023
This study aimed to compare renal function between obese and normal‑weight healthy cats, using intrarenal resistive index (RI), serum symmetric dimethylarginine (SDMA), and serum creatinine, and to identify the variables that might influence intrarenal ...

Subcapsular renal transplant hematoma mimicking acute tubular necrosis

Clinical Case Reports, 2023
Key Clinical Message Kidney transplantation is the treatment of choice for patients with end‐stage renal disease. However, it is associated with serious potential complications, one of which is the subcapsular renal transplant hematoma. Ultrasound is the

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 ...

Renal Resistive Index and Cardiovascular and Renal Outcomes in Essential Hypertension [PDF]

Hypertension, 2013
In the September issue of Hypertension , Doi et al1 analyzed the prognostic implications of elevated ultrasound renal resistive indices (RRI) in hypertensive subjects without overt cardiovascular disease. In line with earlier studies among patients with chronic kidney disease and among kidney allograft recipients, elevated RRI were found to predict ...

Renal Resistive Index and Cardiovascular and Renal Outcomes in Essential Hypertension [PDF]

Hypertension, 2012
Increased renal restive index (RI) measured using Doppler ultrasonography has been shown to correlate with the degree of renal impairment in hypertensive patients. We investigated the prognostic role of RI in cardiovascular and renal outcomes.

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 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.

Determinants and Prognostic Significance of the Renal Resistive Index [PDF]

Pulse, 2015
<b><i>Background:</i></b> The noninvasive assessment of renal hemodynamics is currently possible by assessing the renal resistive index (RRI) derived from intrarenal Doppler arterial waveforms as (peak systolic velocity - end-diastolic velocity)/peak systolic velocity. In this review, we outline the important determinants of the

Effects of Sacubitril/Valsartan on the Renal Resistance Index

Journal of Clinical Medicine, 2022
Background: Sacubitril/valsartan plays a key role in improving left ventricular remodeling and prognosis in patients with heart failure with a reduced ejection fraction (HFrEF). Moreover, some data support its role in preserving renal function. In order to better clarify the effects of sacubitril/valsartan in cardiorenal syndrome, this study evaluated ...
