Abstract

Abstract. The 72 patients with type 2 diabetes mellitus and chronic kidney were examined to clarify Doppler ultrasound capability in assessing the renal circulation. Hemodynamics changes in kidney tissue appeared on early stage of diabetic kidney disease. Intrarenal hemodynamics disturbances in patients with type 2 diabetes mellitus is revealed through a decrease in the minimum blood flow velocity and an increase in the intrarenal vascular resistance parameters. We found the correlation between dopplerographic indicators, kidney functions and other parameters (age, disease duration, glycated hemoglobin level), which play a pathogenetic role in diabetic kidney disease. Serum creatinine level and glomerular filtration rate were indicators of renal hemodynamic changes. Resistant index above 0,7 conventional units, pulsatility index above 1,54 conventional units, systolic diastolic ratio above 3,8 conventional units were ultrasound signs of kidney damage. Patients without standard signs of chronic kidney disease have diagnostically significant index of resistance in 72% of cases, a pulsation index in 50%, a systolic-diastolic ratio in 28%. Renal blood flow examination in right segmental artery area will be use for non-invasive diagnosis and estimation of kidney dysfunction in patients with type 2 diabetes mellitus.
