摘要
Aims: In this study, Doppler parameters were studied in patients with advanced stage renal disease, and the relationship between Doppler parameters and renal disease stage was investigated. Doppler values were evaluated for a cut-off value between normal and end-stage kidney disease group. Materials and methods: 50 patients with chronic kidney disease and 15 patients belonging to the same age group and with normal serum creatinine levels were comprised of the study and control groups. Resistivity and pulsatality indices were measured at the main renal arteries and interlobular arteries at both sides. Results: Statistically significant differences were found between the PI and RI values obtained from the main renal and interlobular arteries. PI sums were compared with those from the control group, and a cut-off value of 2.15 was found, with a sensitivity of 90% and a specificity of 86.7%. Conclusion: Any increase in the RI and PI values obtained from the main renal and interlobular arteries must bring to mind the possibility of advancing renal damage and interstitial fibrosis. Patients with and without renal parenchymal damage can be differentiated by means of comparing the total PI values obtained from the right and left main renal and interlobular arteries.
