Acute Renal Failure
|
Sudden loss of renal function that may be reversible
|
|
Causes of acute renal failure
|
Illness, injury, or toxin that stresses the kidneys.
|
|
Classifications of acute renal failure
|
Prerenal, intrarenal and postrenal depending on the location of the illness in relation to the kidneys
|
|
Prerenal failure
|
Result of insufficient blood flow into the kidneys caused by shock, trauma, severe dehydration or cardiac disease
|
|
Intrarenal failure
|
Result of direct toxic or traumatic injury to the kidney
|
|
Postrenal failure
|
Results when an obstrucction from the lower urinary system causes backup of urine, which injures the kidneys
|
|
Chronic Renal Failure
|
Long, usually slow process that involves a progressive loss of nephrons (loss of more than 75% of nephrons in each kidney to cause obvious illness)
|
|
Chronic renal failure to ESRD
|
May take many years to progress from chronic renal failure to ESRD
|
|
Characterizatons of Chronic Renal Failure
|
Proteinuria, Nocturia, Hypertension, Sodium retention, Anemia, Dyspnea, Uremic symptoms, Nausea and vomiting
|
|
Proteinuria
|
Leaking of protein through the glomeruli in to the renal tubules, and then into the urine
|
|
Nocturia
|
Night time urination due to loss of the ability to concentrate the urine
|
|
Hypertension
|
High blood pressure
|
|
Sodium retention
|
Leading to edema, or water retention/swelling
|
|
Anemia
|
A shortage of red blood cells
|
|
Dyspnea
|
Difficulty breathing
|
