Exam 6: GU Flashcards
Glomerular filtration rate (GFR):
Directly related to renal blood flow, filtration of plasma per unit of time, measured by age, body weight and plasma creating normal is 90-120
Nephron:
The basic unit of the kidney, a sequence of tubes that filter the blood of waste and conserves the fluid and electrolytes that the body needs
Glomerular capillaries:
Major mechanism of the nephron for waste removal and water recycling
Loop of Henle:
A section within the nephron where high amounts of sodium are reabsorbed and urea secreted from the blood into the tubules
Creatinine:
End product of muscle metabolism normal is 0.6-1.2mg/dL
Creatinine clearance:
Measures both blood and urine creatinine in a 24 hour urine volume
Blood urea nitrogen (BUN):
Urea is the product of protein metabolism formed in the liver and excreted by the kidneys. Urea is composite of nitrogenous waste that needs to be excreted
Azotemia:
Increase in blood urea nitrogen (BUN) within the bloodstream
Urine analysis:
Looks at various lab values in the urine such as solute concentration, pH, electrolytes, cortisol, bacteria
Hydronephrosis:
Fluid-filled swollen kidney caused by postrenal kidney dysfunction from urine backing up within the ureter and into the kidney
Urea:
Composite of nitrogenous waste that needs to be excreted
Dysuria:
Pain/burning when voiding
Nocturia:
Urination during the night generally 1 per night is considered normal
Pyuria:
WBCs in the urine
Flank pain:
Back pain caused by kidney infection
