Renal Flashcards
Average kidney size
9-12cm
muscles posterior to the kidneys
-Quadratus Lumborus located anteriorly
-Psoas located posterior lateraly
this fascia anchors the kidneys and adrenal glands and limits infection
Gerota’s Fascia
the renal segment that contains both renal cortex and medullary pyramids
Renal Parenchyma
Bands of cortical tissue within the kidneys, and separate the medullary pyramids
Columns of Bertin
what is the echogenicity of the different layers of the kidneys from light to darkest
-renal sinus
-parenchyma
-renal cortex
-medullary pyramids
blood supply of the kidney
AO—>Renal A.—> Segmental A.—> Interlobar A.—> Arcuate A.—> Interlobular A.—> Afferent Arterioles—> Glomerulus
Lab tests for kidneys
-BUN (Blood Urea Nitrogen): assess renal function and & measures kidneys ability to rid the body of waste
-Creatinine
-Glomerular Filtration Rate (GFR)
-Clearance Tests: patients ability to urinate and how much
Functions of the kidney
-make urine and excrete waste
-regulate blood volume
-regulate blood pressure
-reabsorption of water and sodium back into the body
this hormone is used to increase water reabsorption, constrict blood vessels, regulate sodium homeostasis
ADH (Antidiuretic Hormone)
this hormone helps the kidneys to increase sodium absorption, increase water and potassium excretion
Aldosterone
this is the site for fluid build up between the liver and right kidney
Morrison pouch
a benign bulge on the lateral side of the left kidney; can be easily mistaken for cancer
Dromerdary Hump
an enlargement between the renal cortex and medullary pyramids; same echogenicity as a normal cortex
Column of Bertin Hypertrophied
Both kidneys are fused at the inferior poles and lying over the spine in the mid abdomen
Horseshoe Kidney
