Background: Detection of early renal affection before proceeding to Hepatorenal failure as a complication of liver cirrhosis in children will be helpful in the prognosis of the disease.The objective: Is to detect early hemodynamic changes in children with liver cirrhosis who had normal kidney function, to measure the pulsatility (PI) and resistance (RI) indices in children with different stages of liver cirrhosis, to compare them with apparently and their correlation to some risk factors (severity of cirrhosis, renal infection, blood hemoglobin level and the presence of portal hypertension).Patients and Methods: Thirty children with liver cirrhosis of different stages using Child- Turcotte- Paugh Score, all of them with normal kidney function tests as well as 10 apparently healthy children were included. PR and PI were measured by Doppler spectral wave analysis for patients and control.Results: Both PI index and RI index are significantly higher in all children with liver cirrhosis compared with the control group. Both indices showed highest values with class C compared with class B and A. Each correlated significantly with anemia, renal infection and the presence of portal hypertension.Conclusion: Monitoring of resistance indices (PI and RI) measured noninvasevely by Doppler ultrasound is an effective and easy method for detection of very early renal hemodynamic alternation in childhood cirrhosis and consequently early proper management. PI and RI were closely related to the severity of cirrhosis, renal infection, anemia and the presence of portal hypertension.
