The Renal Arterial Resistive Index and Stage of Chronic Kidney Disease in Patients with Renal Allograft
OBJECTIVE The study investigated the optimal threshold value of renal arterial resistive index as assessed by Doppler ultrasonography determining chronic kidney disease stage 4 or higher in patients with renal allograft. METHODS In a cross-sectional study the renal arterial resistive index were obtained in interlobar arteries by Doppler ultrasonography in 78 patients with renal allograft. The...
متن کاملRelationship Between 'Immediate' Resistive Index Measurement After Renal Transplantation and Renal Allograft Outcomes.
BACKGROUND The arterial resistive index, also referred to as the resistive index (RI) or Pourcelot Index, is a measure of pulsatile blood flow. Previous studies have demonstrated the usefulness of the RI as a predictor of allograft outcomes based on RI measurement in the later stages after transplantation. However, there is little evidence of the predictive value of "immediate" RI measurement w...
متن کاملResistive index and chronic allograft nephropathy evaluated in protocol biopsies as predictors of graft outcome.
INTRODUCTION The presence of chronic allograft nephropathy (CAN) in protocol biopsies is negatively associated with graft survival. Although recent studies have indicated that the resistive index (RI) is a predictor of graft failure, it does not correlate with CAN in stable grafts. We therefore studied the relationship between RI and CAN and examined the predictive value of both parameters on g...
متن کاملResistive Index as a Marker of Renal Pathology in Children with Chronic Kidney Disease; Is It Useful?
Background Chronic kidney disease is a global health concern, its detection and diagnosis in earlier stages is also a great challenge that can alleviate this burden. Kidney biopsy is important to establish histopathological patterns. But, it is invasive. We aimedto evaluate the correlation of renal resistive index (RI) measured by Doppler ultrasound with the prog...
متن کاملResistive index of the remaining kidney in allograft kidney donors.
OBJECTIVES Kidney transplant is the last resort in patients with end-stage renal disease. In living-kidney donors undergoing nephrectomy for transplant; however, morphologic and hemodynamic changes may occur in the remaining kidney with time. If there would be such a change, then it may alter the diagnostic utility of Doppler ultrasound in evaluating diseased conditions of the solitary kidney. ...
