I just had an ultrasound of my kidneys done. Findings Received: Image demonstrates a slightly thinned upper pole cortex noted of the right kidney. The remainder of the right kidney appears grossly normal. The left kidney appears grossly normal. No obstruction is identified. The aorta is normal in appearance without evidence for ectasia. No free fluid is visualized. No stones are noted. There is a subcentimeter cyst noted in the left kidney, lower pole. Impression: Subcentimeter left renal cyst. Focal area of thinning in the upper pole of the right kidney, likely secondary to prior ischemic or infectious insult. No evidence for obstruction or acute abnormality. My doctor is sending me to have another test done where they put dye in my kidneys to further investigate. He is also referring me to a specialist. What does this mean? Should be worried? Also found scattered phleboliths in pelvis. Please help!
