Background This study aimed to evaluate, by B‐mode ultrasound and Doppler ultrasound, the kidneys of one Neotropical primate maintained in captivity. Methods Ten adult intact tufted capuchins ( Sapajus apella ) were evaluated. The morphometric parameters of both kidneys were evaluated and kidney volumes calculated. Color Doppler was used to evaluate renal vascular architecture and to identify arteries of the left kidney. Spectral Doppler was used to measure peak‐systolic velocity, end‐diastolic velocity, and resistive index ( RI ). Results Both kidneys presented homogeneous cortical echogenicity and homogeneous echotexture with preserved corticomedullary differentiation. There was no statistically significant difference between right and left kidneys for all morphometric parameters. RI of the left renal, interlobar, and arcuate arteries were, respectively, 0.75 ( SD , 0.07), 0.70 ( SD , 0.08), and 0.70 ( SD , 0.06). Conclusions Both kidneys showed similar morphometric parameters by B‐mode ultrasound, whereas RI by spectral Doppler decreased progressively from renal artery to interlobar and arcuate arteries.
