Causes of Acute Renal Failure
|
prerenal: decreased blood supply
postrenal: urine flow is blocked intrinsic: kidney tubule function is decreased |
|
|
chronic renal failure
|
fewer nephrons are functioning
remain nephrons must filter more progressive loss of nephron function |
|
|
development of CRF
|
diminished renal researve
renal insufficiency renal failure end stage renal disease |
|
|
diminished renal researve
|
75% nephron loss
remaining nephrons are working as hard as they can no signs or symptoms BUN, creatine normal |
|
|
renal insufficiency
|
75-90% nephron loss
remaining nephrons can no longer regulate urine density polyuria, nocturia slight increase in BUN, creatine |
|
|
renal failure
|
nephrons can no longer keep blood composition normal
uremia dialysis necessary |
|
|
end-stage renal disease
|
renal failure with systemic complications
|
|
|
management of CRF
|
restrict fluids, Na+, K+, Po4
low-protein diet dialysis renal transplant |
|
|
dialysis
|
blood/fluid from patient
pumped past dialysate osmosis/diffusion: wastes removed fluid filtered into the dialysate filtered back to patient |
