SONOGRAPHIC FINDINGS OF PATIENTS WITH CHRONIC KIDNEY DISEASE
Objective: To describe the morphologic and hemodynamic changes of renal interlobar artery on ultrasonography, and to evaluate the relationship between RI and kidney size, glomerular filtration rate, and causes of chronic kidney disease. Materials and methods: A cross-sectional study of 50 chronic kidney disease patients from stage 3, and 50 healthy individuals. RI, peak systolic velocity (PSV), end diastolic velocity (EDV) of renal interlobar artery, renal size was measured. Results: The mean RI in chronic kidney disease group and healthy group was 0.68 ± 0.05 and 0.57 ± 0.04 (p <0.05), respectively. RI increases with the stage of chronic kidney disease. There were statistically significant differences in RI of renal lobar arteries between chronic pyelonephritis and chronic glomerulonephritis (p <0.05). There was strong negative correlation and a statistically significant difference between renal lobar renal artery RI with kidney size (horizontal, vertical and thickness) and glomerular filtration level. Conclusion: Renal artery resistance index in patients with chronic kidney disease was higher than in the healthy group. The greater the kidney failure is, the more reduction in size and renal function, and the more increase in renal artery resistance index.
