Results The average value of interlobar arterial resistance index in patients with hepatorenal
syndrome (0.74+/-0.01) was statistically significantly higher than interlobar arterial
resistance index values measured in liver cirrhosis patients without the signs of azotemia
(0.65+/-0.03) or in those with liver cirrhosis and kidney dysfunction, but without hepatorenal
syndrome (0.67+/-0.01). In all patients with hepatorenal syndrome the value of interlobar
arterial resistance index was over 0.70. In the group of patients with liver cirrhosis and …

Hepatorenal syndrome is the development of renal dysfunction in patients with severe liver
disease in the absence of identifiable causes of renal pathology. At least 40% of patients
with cirrhosis and ascites will develop hepatorenal syndrome during the course of their
disease. The aim of this study was to evaluate the value of renal resistive index [RI]
measured by duplex Doppler ultrasonography in detecting early impairment of renal function
in patients with liver cirrhosis and also its possible role in detecting patients with a high risk …
