Renal Disorders Flashcards
(45 cards)
Anuria
no urine production
GFR
amount of plasma filtered/ time
reflects kidney function
Uremia
toxic wastes/ urine in blood
How much urine is produced per day?
1-2 L
Glomerulus
filters blood
absorbs Na
Tubule
absorbs water, Na, glucose
excretes K, H, HCO3
Tests for Kidney Function and Uremia
creatinine
BUN
Tests for GFR
inulin clearance- best
creatinine clearance- most common
Normal Specific Gravity in Urinalysis
1.001 - 1.035
Hyaline Casts
protein in urine, only a problem if high
slows flow
Elevated in UTIs
leukocyte esterase
Presence of Bilirubin in Urinalysis
liver problems
Starvation Indicator
ketones
Creatinine Rule of Thumb
renal loss doubles for every doubling of serum creatinine above 1 mg/dL (norm)
Elevated in kidney failure
BUN
creatinine
Normal Creatinine Clearance
115 - 125 mL/min
100%
Estimate of Creatinine Clearance
100/ serum creatinine
Adult Polycystic Disease
40+
can result in cysts in liver or pancreas
Kidney Stones
most common upper tract obstruction
calcium oxalate
dull, deep pain in back
becomes severe flank pain
1 Cause of UTI
E. coli
T/F: E. coli is a lactose fermenter
True
Characteristics of Staph saprophyticus
novobiocin resistant
catalase +
coagulase -
can cause UTIs
Lower UTIs
lower abdominal discomfort
burning and pain with urination
low fever
Upper UTIs
affects kidneys
constant flank pain
high fever
