Ultrasonography has been used for diagnosis of various diseases. However, there is a need to determine the normal ultrasound features of various organs to be able to distinguish abnormal features. The kidneys of eight apparently healthy Philippine native goats, four males and four females, 1-3 years old, were examined ultrasonographically using an ultrasound diagnostic equipment with 3.5 MHz , convex-array transducer. After slaughter the kidneys were examined grossly and gross measurement were compared with ultrasound measurements. Samples from the kidneys were processed and examined histologically. Because of anatomical location, visualization of the left kidney was unsuccessful. Only the right kidney can be examined by ultrasonography. The right kidney can be viewed on the right flank from the dorsal region of the 11th intercostal space to the paralumbar fossa at the level of the 2nd lumbar vertebra. The kidney appeared smooth and bean-shaped. The renal cortex and pelvis were seen as hyperechoic structures. The renal medulla appeared uniformly gray or hypoechoic while the medullary pyramids were viewed as hypoechoic circular structures. No significant differences were observed in the means ± S.D. values of length, width and thickness of the result kidney between ultrasonographic and gross measurements and between males and females. Gross and histologic examinations reaveled no lesions in all kidneys of the animals.
