ABSTRACT

Assuming that the duplex Doppler sonography might be useful in predicting the disease evolution of hemorrhagicfever with renal syndrome, we compared the resistive index (RI) with the clinical and laboratory findings in 18patients. We underwent 30 duplex Doppler examinations in 18 patients; one examination in nine, two examinations insix, and three examinations in three patients. Duplex Dopper waveforms were obtained from the main, segmental,interlobar, and arcuate arteries of both kidneys, and the RI was calculated for each study. In oliguric phase, themean RI was high (average, 0.94), and the serum BUN(averate, 92.3mg/dl) and creatinine(average, 10.4mg/dl) levelswere elevated. In diuretic phase the mean RI was normalized (average, 0.7), and the serum BUN(average, 31.1mg/dl)and serum creatinine (average, 2.9mg/dl) levels were low. There was statistically significant correlation betweenthe mean RI and the serum levels of BUN and creatinine and 24 hour urine output (P<0.001). We conclude that themean RI is a useful indicator in predicting the disease evolution in patients with hemorrhagic fever with renalsyndrome.
