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

In addition to conventional renal USG, SWE was performed. 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 value of 5.0 kPa. The age, creatinine and estimated glomerular filtration rate levels, and presence of diabetes and hypertension were significantly higher in the increased CS group (p |

The increased CS value was taken as the limit value of 5.0 kPa. The age, creatinine and estimated glomerular filtration rate levels, and presence of diabetes and hypertension were significantly higher in the increased CS group (p<0.05). It was found that the cortical echogenicity increase (stage I-II), renal resistance index (RRI), and acceleration time values were significantly higher in patients with increased CS (p<0.05). When logistic regression analysis was performed to identify patients with increased CS, we found that RRI, diabetes presence, and cortical echogenicity stages I and II independently predicted an increase in CS (p<0.05). According to this analysis, RRI (every-0.1), diabetes, and cortical echogenicity stages I and II increased the risk of increased CS by 2.3 times, 14%, 10.5% and 18.2%, respectively.
