Evaluation of Kidneys with Renal Doppler Ultrasonography and Ultrasound Elastography in Patients with Type 2 Diabetes Mellitus

Introduction: The aim of this study early recognize diabetic nephropathy by ultrasound elastography.This study was to predict the possibility of developing diabetic nephropathy without the need for renal biopsy. Methods:This study included 100 patients and 100 healthy volunteers. Shear wave elastography examination were taken of the renal parenchyma and the Resistive Index values were taken renal artery. Results:.In the patient group, the elastography values were measured as 7.02±2.15 kPa in the right kidney parenchyma and 6.90±2.09 kPa in the left. In the control group, the elasticity values were measured as 4.14±0.98 kPa in the right kidney parenchyma and 4.11±0.85 kPa in the left. The RI mean values were determined as 0.59±0.05 in the right kidney and 0.59±0.04 in the left kidney in the patient group and 0.52±0.05 in the right kidney and 0.52±0.05 in the left kidney in the control group. Conclusion: The elastography values and the RI values were significantly higher in the patients with Type 2 DM than in the control group. Thus, it can be concluded that it is possible to determine renal fibrosis and predict the possibility of diabetic nephropathy development with the non-invasive methods of SWE and colour Doppler US, without the need for biopsy.
