You could go to your Radiology Department and ask the radiologists who routinely examine this cohort of patients.

For what purpose do You want Ultrasound images for chronic renal disease?

The radiologyassistant.nl homepage

has nice images of kidney cystic and solid masses, among others

you can look at radiopedia.com

According to the results of ultrasonography, the most diagnostic signs of chronic kidney disease can be:

1. Increasing echogenicity of the parenchyma along with a decrease in its thickness;

2. Fuzzy contours with surrounding tissue and renal sinus;

3. Deterioration of differentiation of cortical and medulla layers, reduction of pyramids or disappearance of their image;

4. Expansion of the cup-and-pelvis system with thickening of their walls;

5. Deterioration of visualization of vascular pattern - loss of tree or branch structure;

6. Increase of the index of resistance of segmental renal arteries above 0.65

7. The presence of calcification in the parenchyma.

The combination of 3-4 symptoms increases the likelihood of chronic kidney disease.

In this case, the results of laboratory studies will help evaluate the activity of the inflammatory process in a given period of time

Good luck!
