Ultrasonography of the normal kidney in the cynomolgus monkey (Macaca fascicularis ): morphologic and Doppler findings

The purpose of this study was to obtain sonographic measures of normal kidneys in cynomolgus monkeys (Macaca fascicularis). The kidneys of 27 healthy female cynomolgus monkeys were examined with two-dimensional, duplex and power Doppler under sedation or general anesthesia. Except for shape and sinus echogenicity, the kidneys of the cynomolgus monkey are morphologically similar to those of humans. Left kidney volume estimations (mean, 5.1 cm3) were significantly smaller (P
