A study was performed on fifty normal goats for radiographic (only 20 animals), and sonographic (the all 50 animals) investigations. Radiographic results revealed that, both kidneys had bean shaped and smooth contour. The right kidney position was constant due to its relation with the liver, while, the left kidney was mobile and its position varied according to the degree of fullness of the rumen due to its long mesentery. The sonographic results revealed the position, shape, dimensions and echogenicity of kidneys, by using 3.5/5.0 MHz curved transducer and 6.0/8.0 MHz linear transducer. The renal capsule was represented by a very fine echogenic lines around the kidney that couldn’t be distinguished from the peri-renal fat. The cortex was more echogenic than the medulla and had uniform finely granular hypoehoic pattern. The corticomedullary junction was slightly more echogenic than the cortex due to the presence of the arcuate arteries. The medulla was observed as hypoechoic area interrupted by bright echogenic lines representing the recesses and interlobular arteries that gave the appearance of typical medullary pyramids. The dimensions of the right kidney were 5.32 ± 0.12, 2.79 ± 0.07, 0.64 ± 0.01, 1.52 ± 0.03, 2.74 ± 0.09, 1.27 ± 0.06, 1.25 ± 0.05, and 1.72 ± 0.09; and the dimensions of the left kidney were 5.34 ± 0.12, 2.80 ± 0.07, 0.65 ± 0.01, 1.55 ± 0.03, 2.76 ± 0.09, 1.26 ± 0.06, 1.28 ± 0.05, and 1.73 ± 0.1, for the length, width, cortical thickness, medullary thickness, depth, diameter of renal sinus, diameter of renal parenchyma, and circumference of renal pyramids respectively.
