بررسی حدود طبیعی معیارهای سونوگرافی داپلر در شرایین کلیویEvaluation of Normal Doppler Indices in Renal Arteries

    Background & Aim: Doppler ultrasonography is important in diagnosis of renal diseases by demonstrating vascular anatomy and hemodynamics. There is not any fix doppler indices in all of the references and it is suggested that each center should have its own standards. Also it is proved that biologic indices are not the same in different societies. The present study was performed on normal Iranian population to measure normal limits for renal doppler indices. Patients & Methods: In this research ultrasonography was done on 256 healthy people including 126(49.2%) female and 130(50.8%) male. The mean age was 31.1 years with standard deviation of 8.64. The minimum age was 14 years and maximum age was 57 years. Doppler indices were measured in all of the cases and normal limits were calculated. Results: In main renal arteries PSV mean was 86.01(87.80, 84.25) cm/s and EDV mean was 39.01(40.40, 37.80) cm/s. In intrarenal arteries mean PSV was 75.32(77.12, 72.89) cm/s, mean EDV was 32.23(33.41, 31.45) cm/s, mean RI was 0.55(0.56, 0.54) and mean AT was 29.35(30.75, 28.35) ms. Conclusion: The obtained values are normal renal doppler indices in healthy Iranian population and we suggest that it should be used in clinical studies.
