What Does Low Echogenicity in Renal Parenchyma Indicate?

1. Low echogenicity in bilateral renal parenchyma refers to the echogenicity below the normal structure of renal tissue, generally caused by renal cysts, renal abscesses, and other reasons.

2. Normal renal parenchyma displays a normal and uniform echogenicity on B-mode ultrasound. Low echogenicity in bilateral renal parenchyma describes an abnormality in the renal parenchyma, which may be due to local fluid-like tissue such as renal cysts, renal abscesses, renal cell carcinoma, or developmental abnormalities such as renal column hypertrophy, resulting in the renal parenchyma being below the normal structure of renal tissue.

3. Another description of renal parenchyma abnormalities on B-mode ultrasound is enhanced echogenicity in bilateral renal parenchyma, which may be caused by primary or secondary renal diseases such as chronic nephritis, nephrotic syndrome, hypertensive nephropathy, and diabetic nephropathy. These lesions can cause partial glomerular sclerosis, renal tubular atrophy, renal interstitial fibrosis, etc., leading to enhanced echogenicity.

4. If these two conditions occur, patients need to undergo enhanced CT scans and MRI scans. When necessary, biopsy via puncture is required to confirm the cause of the disease, and patients should follow the doctor's advice for treatment.
