99mTc -DMSA scintigraphy - an advance diagnostic modality for evaluating renal cortical function and scarring of kidney in dogs with pyelonephritis.

摘要

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+or-4.22 and 51.70+or-5.7 mm for right kidney, whereas, for left kidney 61.26+or-3.52, 50.1+or-7.23 mm in healthy and renal failure dogs. Kidney widths [mm] were 41.28+or-1.16, 32.9+or-3.92 and 38.52+or-2.08, 31.9+or-3.76for right and left kidney of healthy and renal failure dogs respectively. Observed cortical thickness [mm] was 6.35+or-0.64, 3.73+or-1.80 and 6.14+or-0.28, 2.67+or-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+or-2.11 and 57.52+or-3.80 for right kidney, whereas, for left kidney 49.34+or-2.11, 41.99+or-2.75 in healthy and renal failure dogs.
