Relationship Between Renal Resistive Index and Increased Renal Cortical Stiffness in Patients with Preserved Renal Function

Abstract

Objective: We aimed to investigate the relationship between cortical stiffness (CS) determined by shear wave elastography (SWE)and conventional ultrasonography (USG) parameters, and identify the determining parameters that increased CS.Methods: In this study, 229 patients who underwent renal USG were included. In addition to conventional renal USG, SWE wasperformed. Patients were divided into two groups: with increased CS and without increased CS.Results: The median CS value of the patients included in the study was 4.92 kPa. The increased CS value was taken as the limit valueof 5.0 kPa. The age, creatinine and estimated glomerular filtration rate levels, and presence of diabetes and hypertension were significantlyhigher in the increased CS group (p
