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 ...

Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi [PDF]

Brazilian Journal of Medical and Biological Research, 2001
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function.

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

Intrarenal resistive index conundrum: systemic atherosclerosis versus renal arteriolosclerosis

Renal Failure, 2019
Background: We aimed to evaluate the relationship between biopsy-proven kidney lesions, subclinical markers of atherosclerosis and intrarenal resistive index (RRI) in chronic kidney disease (CKD) patients.

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 ...
