The Role of Renal Resistive Index in Assessing the Early Renal Dysfunction of Cirrhosis

BACKGROUND: Hyperdynamic circulatory state in cirrhosis leads to splanchnic vasodilatation and renal vasoconstriction in that leads to the development of HRS. AIM OF THE STUDY: To measure the intrarenal resistive index in patients with and without ascites and compare the value of RI with Child Pugh and MELD scoring systems. METHODS: 100 patients with cirrhosis liver were selected for the study. Bilirubin,INR and serum creatinine were measured and patients were subjected to sonographic evaluation of abdomen followed by Doppler Ultrasound of both kidneys and RI values were obtained. RESULTS: 71 patients had RI > 0.7 (0.7 kept as cut-off value). 29 patients had RI < 0.7. Patients with severe ascites had more RI than the patients with absent or mild to moderate ascites and had significant comparability with CTP scoring and MELD scoring systems. CONCLUSION: Value of RI was higher in patients with cirrhosis and comparable prognostic value with MELD and CTP scoring system.
