Intrarenal Resistive Index after Renal Transplantation

New England Journal of Medicine, 2014
Naesens et al. (Nov. 7 issue)1 published their findings of a well-conducted study looking at the relationship between intrarenal resistive indexes in renal allografts and allograft dysfunction. With regard to the protocol-specified measurements, higher resistive indexes were not associated with allograft dysfunction but were associated with older ...

Renal Arterial Resistance Index

2015
The kidney is a profusely vascularized organ which, unlike other organs, does not regulate renal blood flow (RBF) mainly by oxygen demand. Reflex (myogenic effect and tubular-glomerular feedback) and neurohormonal mechanisms modulate RBF and renal resistances by regulating the tone of afferent and efferent arterioles as well as that of the major ...

Role of resistive index in renal colic

Urological Research, 2007
We studied the role of duplex Doppler ultrasonography in the diagnosis of renal obstruction caused by ureteral calculi. Using duplex Doppler sonography, we evaluated the intrarenal hemodynamics of 27 patients who presented to the emergency department with renal colic.

Renal histomorphometry and resistance index in children with renal disease

Journal of Clinical Ultrasound, 2000
The aim of this study was to examine the relationships between the renal resistance index (RI) and histomorphometric variables measured in children with glomerular or nonglomerular renal disease. Patients and Methods The medical records, sonography reports, and biopsy specimens of 30 children with glomerular or nonglomerular renal disease (mean age, 11.

Renal colic in pregnant women: role of renal resistive index

Urology, 2000
To investigate the value of the renal resistive index (RI) in the identification of acute renal obstruction in pregnant women.The study included 22 pregnant women with acute unilateral ureteral obstruction due to a stone disease (group A), 71 normotensive pregnant patients without loin pain (group B), and 20 nonpregnant women of child-bearing age with ...

EVALUATION OF REFLUX KIDNEY USING RENAL RESISTIVE INDEX

Journal of Urology, 2001
We clarified the relationships of the renal resistive index, reflux and renal scarring.The resistive index in the interlobar artery was measured using power Doppler ultrasonography in 22 patients with reflux (reflux group), 13 with postoperative or resolved reflux (previous reflux group) and 20 who served as controls.Resistive index values in 11 ...

Doppler sonographic renal resistance index in healthy children

European Radiology, 2000
The objective of the study was to determine the values of Doppler resistance indices (RIs) in intrarenal arteries in healthy children. Color duplex Doppler sonography of intrarenal arteries was performed in 163 children and 58 adult patients, with the absence of clinical or laboratory pathologic changes of the urinary tract.

Intrarenal Resistive Index Correlates with Renal Pelvis Pressure

Journal of Urology, 1994
Elevation in the intrarenal resistive index has been suggested by many to be a physiological parameter useful for detecting functionally significant hydronephrosis. It is currently unknown whether the intrarenal resistive index changes truly reflect the changes in collecting system pressure or whether they are simply a coincidental epiphenomenon.
