Renal ultrasound showed i have mild cortical thinning of the right kidney greater than the left but no hydronephrosis, stone, or mass bilaterally. what does this mean? right kidney measures 10.6 by 3.6 by 4.6. left kidney 10 by 4.5 by 4.8?

Nothing to worry about. It is not uncommon to see the normal kidney take slightly differing shapes in different individuals. As long as your kidney function is normal(serum Creatinine is less than 1.4Mg/dl), You can ignore the cortical thinning in your kidney.

US images are very technique's dependence, radiologist only read what he sees. With the reported sizes of your kidneys, the right cortical thinning of the right is likely a technical error.

The measurements you provided are not a cause for concern. If your eGFR is normal, i.e. greater than 90, and there is no protein in urine, your kidneys are okay. Wish you good health!
