AIMS The aim of this study was to calculate the normal values of renal functional reserve in healthy individuals measuring the resistive index and pulsatility index using Doppler ultrasonography. MATERIAL AND METHODS Forty healthy volunteer adults were included in the study. Their basal resistive index and pulsatility index values were measured and after oral protein load at 30th, 75th and 12...

OBJECTIVES There are conflicting data regarding the use of some measured indices by Doppler ultrasound such as the resistive index and the pulsatility index in predicting renal allograft dysfunction. This study sought to evaluate the association of early postoperative Doppler indices and 3-month serum creatinine levels in renal transplant recipients. MATERIALS AND METHODS During a 1-year peri...

The previous issue of Critical Care reports new data on renal resistive index in critically ill patients. Although high renal resistive index may indeed be associated with acute kidney injury, the existence of several determinants of this index, of which renal resistance is only one among many, obscures the usefulness of this index in clinical practice.

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...

OBJECTIVES Our purpose was to investigate cervical lymphadenopathies by using color Doppler spectral analysis and power Doppler ultrasonography methods as well as B-mode ultrasound and to classify them as malignant or benign lesions and to compare the results with the histopathological findings. PATIENTS AND METHODS Sixty-nine lymph nodes of 69 patients were evaluated with color and power Dop...

Hepatorenal failure, a well-recognized complication of established liver disease, is characterized by early renal hemodynamic changes (vasoconstriction) before clinically recognized kidney disease. This renal vasoconstriction (increased renal vascular resistance) should be detectable noninvasively by Doppler ultrasonography. We studied whether renal Doppler ultrasonography detects abnormalities...
