3. Fig GU 35-1 Chronic renal failure. Parasagittal sonogram of the right kidney (RK) shows that the echogenicity of renal cortical tissue has increased to such an extent that it is now greater than that of the hepatic parenchyma (L). The renal medullary pyramids (P) are clearly visible in the right kidney. (D, diaphragm; H, head.) 2

4. Fig GU 35-2 Renal transplant rejection. (A) Sagittal supine sonogram shows enlargement of the renal transplant with increased sonolucency of the medullary pyramids (black arrows) and thinning of the central echogenic hilar structures (white arrow). (B) Another patient with markedly dilated medullary pyramids of an enlarged renal allograft. 40
