Table 3.
The sum of abnormalities observed on ultrasonography of the kidneys in 133 Ragdoll and 62 control cats. The parameters that were assessed to calculate this sum were abnormalities in renal capsule, renal shape, cortical echogenicity, medullar echogenicity, corticomedullary demarcation and renal pelvis; presence of small left kidney (<3.2 cm), small right kidney (<3.2 cm), large size difference between left and right kidney (absolute difference >0.7 cm), medullary rim sign(s), dystrophic mineralisation(s), cavitary lesion(s), solid mass(es)/nodule(s) and segmental cortical lesion(s). Multiple abnormalities of the same category (eg, multiple segmental cortical lesions, multiple cavitary lesions, etc) in the same cat were counted only once
