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
