Chronic kidney disease ckd also known as chronic renal failure is a progressive loss of glomerular function caused by a long standing renal parenchymal disease it is present when the glomerular filtration rate gfr is less than 60 ml min 1 73 m 2 for three consecutive months or greater than or equal to this value in patients with a kidney damage that is present for three or more months 1.
In the kidney it is calculated by quantifying the velocity of blood flow from the doppler waveform of intrarenal arteries. The kidney has a fibrous capsule which is surrounded by perirenal fat. The kidney itself can be divided into renal parenchyma consisting of renal cortex and medulla and the renal sinus containing renal pelvis calyces renal vessels nerves lymphatics and perirenal fat. The arcuate arteries running along the junction of the cortex and medulla or the interlobar arteries running between the medullary pyramids are targeted.
