ABSTRACT
In human beings, intrarenal blood flow impedance, expressed as the resistive index (RI) and obtained by duplex Doppler ultrasonography, has been used to aid in diagnosis and prognosis of renal failure. Higher than normal values for RI were obtained in 3 of 4 dogs with acute tubular necrosis (ATN) and in 5 of 10 dogs with glomerulonephrosis (GN). Normalization of RI was observed in 2 dogs with ATN evaluated serially during treatment. Increased RI values were obtained in 9 of 10 cats with nonobstructive renal disease and in 2 of 5 cats with obstructive renal disease. Normalization of RI was observed in 3 cats with renal failure in which treatment was effective (1 with obstruction; 2 with nonobstructive disease). The magnitude of increase in RI did not correlate with the magnitude of concurrent renal dysfunction. These results suggest that duplex Doppler evaluation of intrarenal RI is more useful as an ancillary diagnostic technique in azotemic dogs with ATN than in those with GN and in azotemic dogs with nonobstructive than in those with obstructive disease.
