Multiple subcentimeter nonobstructing right renal stones. Hypoechoic focus upper pole left kidney with internal complexity. While this may represent a complex benign cyst, it is best considered indeterminate. Would pay special attention to this lesion on future surveillance scans. If further characterization is clinically indicated, would recommend dedicated renal CT.
