Renal Resistive Index: A Non-Invasive Indicator of Hepatorenal Syndrome in Cirrhotics
Journal Title: The Indian Practitioner - Year 2016, Vol 69, Issue 6
Abstract
Introduction: Hepatorenal syndrome (HRS) is defined as unexplained kidney failure in a patient with liver disease. The poor prognosis is due to both liver and renal failure, the latter being due to intra-renal vasoconstriction. The intra renal arterial doppler is a non-invasive tool used to study the extent of this vasoconstriction. Aim: To determine if the Intra Renal Doppler helps in indicating Hepatorenal syndrome in established cases of Liver Cirrhosis. Material and Methods: 30 Cirrhotics aged above 18 years with no prior or co-existing renal disorders were subjected to LFT, RFT, CBC, urine examination, viral markers, USG abdomen and the intra renal artery doppler for resistive index calculation. Resistive index (RI) was calculated using the formula RI = (peak systolic flow – peak diastolic flow)/ peak systolic flow and RI ≥ 0.77 was taken as diagnostic of Hepatorenal syndrome. Results: Out of the 18 patients whose RI < 0.77, 17 had normal creatinine.12 patients who had raised RI, 6 had raised creatinine (2.68), while the other 6 had normal creatinine (0.88) implying that RRI is an early indicator of HRS even before creatinine could rise to fulfil the criteria for HRS. Conclusion: Renal resistive index (RI) is a useful tool for indicating Hepatorenal syndrome in Cirrhosis of the Liver.
