“…In addition some renal Doppler US parameters, but no one of liver Doppler US parameters, correlate with serum urea and serum creatinine levels. Similar results were reported when comparing patients with liver cirrhosis with and without ascites and with first signs of renal failure [13, 20]. The data about correlation between RI and the glomerular filtration are controversial [1, 13].…”

“…The evaluation of the renal hemodynamics in patients with liver cirrhosis is based mainly on the index of resistance of the intrarenal arteries [11–20]. Renal vasoconstriction has been documented in several series of cirrhotic patients on the base of increased resistive index [1].…”

“…Renal vasoconstriction has been documented in several series of cirrhotic patients on the base of increased resistive index [1]. In patients with refractory ascites, as well as in subjects with serum creatinine within the normal range, increased RI seems to be correlated with a higher risk of subsequent deterioration in renal function [1, 12, 15, 17–20]. In our study in contrast to liver Doppler US parameters, all intrarenal blood flow Doppler parameters except RA peak systolic velocity show a significant association with the severity of liver cirrhosis, evaluated by both Child's and MELD scores.…”

“…The detailed investigation of the renal blood flow in real time is a challenge for the investigators. Many authors evaluate the hemodynamics of portal vein and hepatic arterial blood flow, as well as renal arterial blood flow [2–20]. There are limited studies on simultaneous evaluation of liver and renal blood flow using Doppler methods in real time [21].…”

Introduction. There are limited studies on simultaneous evaluation of liver and renal blood flow using Doppler methods. We evaluated and compared the changes of liver and renal Doppler US parameters in patients with liver cirrhosis according to the degree of liver disease. Material and Methods. We assessed a large spectrum of liver and renal Doppler US parameters in 67 patients with liver cirrhosis. Results. Significant differences between Child's classes or score, as well as MELD score, were observed in all investigated intrarenal blood flow Doppler US parameters, except renal artery peak systolic velocity, but only in some of the hepatic ones. The deviations of renal Doppler US parameters were also related with the complications of liver cirrhosis, as well as serum urea and creatinine levels. There was relationship between Doppler US parameters of hepatic artery and the corresponding renal artery Doppler US parameters. The changes of Doppler US parameters were age independent. Conclusion. Our results show, renal Doppler US parameters correlate with the severity and complications of liver cirrhosis. Because of dynamic deviations of renal Doppler US parameters with advance of liver cirrhosis, we recommend Doppler US of renal artery as a part of follow up of these patients.

BACKGROUND One of the earliest diagnostic signs of hepatorenal syndrome in patients suffering from liver cirrhosis is an increase in the renal vascular resistive index (RI). In this study, the impact of propranolol on decreasing this index and to postpone the probability of hepatorenal syndrome has been investigated. METHODS In the current research, 30 patients with liver cirrhosis with different age and sexes have been enrolled. Demographic data and complete medical history have been collected using a specific questionnaire. At first, renal artery Doppler ultrasonography was performed to determine the RI. The patients were then treated with propranolol, and under supervision, the dose of the drug was increased gradually every 3 to 5 days to reach the target of 25% decrease in resting heart rate. One month after reaching the target dose of the medicine, Doppler ultrasonography was repeated for the patients and the second RI was compared with the pretreatment ones. RESULTS According to our results after treatment with propranolol, a significant decrease of RI was observed ( p < 0.01). However, there was no significant difference in the glomerular filtration rate (GFR) before and after treatment with propranolol ( p = 0.290). In our study, we found that administering propranolol was associated with significant changes in RI and GFR between the patients with compensated and decompensated cirrhosis (mean change: -0.005 ± 0.017 vs. -0.058 ± 0.045; p < 0.01 for RI and -4.226 ± 17.440 vs. 13.486 ± 12.047; p < 0.01 for GFR in patients with compensated and decompensated cirrhosis, respectively). CONCLUSION Propranolol reduces renal vascular RI in patients with cirrhosis. The response rates in the patients with decompensating cirrhosis were significantly higher than the patients with compensating cirrhosis
