Hi Dr. I’m a 32 y/o woman. My ultrasound indicates “increased renal echogenicity”, but my creatinine BUN and eGFR levels are all normal. My kidney sizes are also normal. Anything to worry about? Thank you.

The echogenicity of the kidneys on ultrasound examination is usually a judgement call on the part of the radiologist who is interpreting the study. It is usually based on a comparison to the echo density of the liver or the spleen. In some cases this may be significant and in other cases, it may not be significant. I suggest that you consult with your physician for his or her opinion of the study.
