I am unable to make a specific diagnosis based on the information that you provide. Chronic kidney disease (CKD) is a diagnosis based on finding an estimated glomerular filtration rate (eGFR) that is consistently less than 60 milliliters per minute per 1.73 meters squared and is present for greater than 3 months. The amount of protein in your urine is normal. The ultrasound finding that you mention could be consistent with CKD, but I would have to review these findings myself. I suggest that you consult with your physician for further opinions.
