Prospective study was made performing Doppler ultrasonographic exams of fifty kidneys belonging to Persian adult cats. The animals were classified as healthy by laboratorial exams and measurement of arterial systolic pressure. Maximal systolic blood flow velocity (VPS), minimal diastolic blood flow velocity (VDF) and resistivity index (IR) of renal arteries (AR) and aorta (AO) of each animal were evaluated. The results are: left renal artery VPS 40.96±9.08cm s-1 and IR 0.55±0.07; right artery VPS 41.39±9.89cm s-1 and IR 0.52±0.07. It was not observed any statistical significant difference among the sides. Considering both renal arteries it was calculated VPS 41.17±9.40cm s-1 and IR 0.53±0.07. Renal arterial diameter was 0.15±0.02cm. The aorta VPS obtained was 53.17±13.46cm s-1 and the diameter was 0.38±0.04cm. Correlation velocities of renal artery and aorta resuled in a relation 0.38 as minimal and 1.52 as maximal, with 0.82±0.30.
