Abstract：Objective To observe the changes of renal hemodynamics in diabetes mellitus with diabetic nephropathy(DN) with color Doppler flow imaging(CDFI). Methods The renal hemodynamics of arcuate artery flow were studied with CDFI in 35 patients with diabetic renal failure among age matched 35 cases of clinical DN and 30 cases of normal volunteers. Results The pulsative index and resistance index of the patients with diabetic renal failure were significantly higher and the systole peak velocity and mean velocity were lower than those of clinical DN. Compared with normal controls, the PI and RI in the patients with clinical DN or diabetic renal failure were greatly increased. The end-diastolic velocity of blood flow and the mean velocity were significantly reduced in the patients with diabetic renal failure. The peak velocity of blood flow during systole was increased and the end-diastolic velocity of blood flow was reduced in the patients with clinical DN. Conclusion CDFI is an effective method in evaluation of renal hemodynamics in DN, and CDFI might be valuable for forecasting the renal injury and judging the renal failure.
