This study compared the renal cortical function and relative kidney uptake in healthy and renal failure dogs. More than 2 mg/dl serum creatinine and chronicity of illness was the criterion for dogs to be included in renal failure group. The measured kidney length [mm] were 62.85 ± 4.22 and 51.70 ± 5.7 mm for right kidney, whereas, for left kidney 61.26 ± 3.52, 50.1 ± 7.23 mm in healthy and renal failure dogs. Kidney widths [mm] were 41.28 ± 1.16, 32.9 ± 3.92 and 38.52 ± 2.08, 31.9 ± 3.76for right and left kidney of healthy and renal failure dogs respectively. Observed cortical thickness [mm] was 6.35 ± 0.64, 3.73 ± 1.80 and 6.14 ± 0.28, 2.67 ± 1.68 for right and left kidney of healthy and renal failure dogs respectively. Cortical thinning was a sign of pyelonephritis in the dogs of group II. The relative kidney uptake [respective kidney count/[left + right kidney count] were 49.66 ± 2.11 and 57.52 ± 3.80 for right kidney, whereas, for left kidney 49.34 ± 2.11, 41.99 ± 2.75 in healthy and renal failure dogs.
