Pre/Intra/Post Renal Fast Facts Flashcards
Urine osmolality in PRErenal acute kidney injury
Greater than 500
Lysosomal storage Dz with late progressive renal failure and CV Dz
Fabry Dz
*alpha-gactosidase A deficiency
Increased BUN/Creatinine ratio and decreased fractional excretion of Na+
Pre renal Azotemia
Fractional Excretion of Na+ with Intrinsic acute renal failure
Greater than 2%
With this type of acute kidney injury, pt has low BUN reabsorption which leads to decreased BUN/Creatinine and increased FENa+
Intrinsic
With this type of acute kidney injury, kidneys retain Na+/H20 and BUN to conserve volume. This leads to increased BUN/Creatinine and decreased FENa+
Pre renal Azotemia
FENa+ in Prerenal acute kidney injury
less than 1%
This type of acute kidney can be caused by:
- Stones
- BPH
- Neoplasia
- Congenital Anomaly
PostRenal
A recombinant cytokine used to Tx anemia, especially in renal failure. Functions as erythropoietin
Epoetin-alpha
Don’t use these diuretics with renal failure pts!
Sparing
Urine Na+ with intrinsic and post renal acute kidney injury
greater than 40mEq/L
Urine Osmolality with intrinsic and post renal acute kidney injury
less than 350 mOsm/kg
When taking these drugs, Pts must drink lots of water. If not, they may develop obstructive crystalline nephropathy and acute renal failure.
Acyclovir
Famciclovir
Valacyclovir
Don’t forget, renal failure can cause this condition - possibly leading to pericarditis
Uremia
This bacteriostatic Antibiotic is safe for renal failure Pts because it is excreted fecally
Doxycycline
