Sonographic evaluation of hypertension: Role of atrophic index and renal resistive index [PDF]

The Journal of Clinical Hypertension, 2022
Hypertension can cause structural and functional renal damage. Intrarenal ultrasound parameters have been extensively investigated in hypertensive patients and among the parameters introduced, the renal resistive index (RI) is associated with the ...

Importance of Renal Resistive Index as a Prognostic Marker in Unilateral Hydronephrosis Due to Ureteropelvic Junction Obstruction

Journal of Indian Association of Pediatric Surgeons
Background: Hydronephrosis is the most common congenital anomalies of the urinary tract. There are various diagnostic modalities which are currently used for diagnosis and follow-up such as ultrasound, renal scintigraphy, intravenous urography, and ...

Exploring the Utility of Renal Resistive Index in Critical Care: Insights into ARDS and Cardiac Failure [PDF]

Biomedicines
The renal resistive index (RRI), a Doppler ultrasound-derived parameter measuring renal vascular resistance, has emerged as a promising non-invasive tool to evaluate renal hemodynamics in critically ill patients, particularly those with acute respiratory

Bosentan Does Not Affect Renal Resistive Index in Scleroderma/Systemic Sclerosis Patients

Kidney & Blood Pressure Research, 2023
Introduction: If properly evaluated, chronic kidney disease can be found in up to 50% of patients with systemic sclerosis (SSc). The renal resistive index (RRI) is a marker of intrarenal vascular resistance and can predict SSc-associated vasculopathy ...

Renal resistive index as a marker of histopathological damage in diabetic and non-diabetic chronic kidney disease

The Egyptian Journal of Radiology and Nuclear Medicine, 2023
Background Chronic kidney disease is a worldwide public health problem with diabetes being the leading cause. Renal resistive index derived by Duplex Doppler sonography, has been in use clinically to examine intrarenal hemodynamic abnormalities. However,

Role of Ultrasound and Colour Doppler in Diabetic Nephropathy-Correlation with Biochemical Parameters [PDF]

International Journal of Anatomy Radiology and Surgery, 2019
Introduction: Ultrasound and Doppler are non-invasive modalities for evaluation of renal diseases. Renal sonography has been used fairly routinely in patients with azotemia to exclude possible obstructive uropathy, to measure the size of kidneys and ...
