Study of development changes in kidneys of dogs by using 2D and 3D ultrasonography

The present study was undertaken in six apparently healthy pups of mixed mongrel breed from the same litter, to study developmental changes using 3D ultrasound machine (Nemio-XG: Toshiba, Japan). In kidneys the cortex appeared hypoechoic and medulla was anechoic up to 3^rd month of age, where as the same was hyperechoic and medulla was hypoechoic up to end of the study (8^th month). The kidney parameters observed were length, width, circumference, cortical thickness and medullary thickness, which showed linear increase with age. In 3D appearance of the renal structures (renal pelvis, renal sinus) were clearer than 2D ultrasonogram.
