Value Renal Artery Resistance Index in Quantitative Analysis Renal Function Injury in Chronic Kidney Disease/ZHENG Yinhai， HE Ziyang， TANG Qiyuan.//Medical Innovation China， 2025， 22(10)： 157-161

    [Abstract]Objective：To explore thevalue renal artery resistance index in quantitative analysis renal functioninjury inchronickidneydisease.Method：Atotal 76patientswithchronickidney disease admittedto from May 2022to May 2023 were included in the case group， and30volunters whounderwentphysicalexamination inthehospitalatthe sametime were selectedtobe included in the healthgroup.Therenal artery flow correlation indexes[systolic peak flow velocity (Vs)，diastolic peak flow velocity (Vd)， renal artery resistance index (RRl)] were compared between the two groups. Receiver operating characteristic(ROC)curve wasused to analyze thediagnosticvalue renalartery flow correlation index in chronic kidney disease. According to creatinine clearance (Ccr)， patients were divided into mildly impaired group ( n =35)， moderately impaired group ( n =24) and severely impaired group ( n =17). Vs， Vd and RRI in patients with different renal function injury were compared.Result：RRI in case group was higher than that in health group ......
