What are some of the common causes of Prerenal Intrarenal or Postrenal acute kidney failure?
Causes of Acute Kidney Injury
| Prerenal | |
|---|---|
| Intrarenal vasoconstriction (hemodynamically mediated) | |
| Vascular | |
| Renal vein thrombosis, malignant hypertension, scleroderma renal crisis, renal atheroembolic disease,* and renal infarction | |
| Postrenal |
What are the 3 types of renal failure?
Acute renal failure (ARF) can be divided into three main types: perennial, renal, and postrenal.
What is Prerenal Intrarenal Postrenal?
Pre-renal, generally in which decreased renal blood flow results in a drop in GFR. Intrinsic/intra-renal, in which a disease process causes damage to the kidney itself. Post-renal, in which a process downstream of the kidney prevents drainage of urine (urinary tract obstruction)
What are the Prerenal Intrarenal and Postrenal causes for glomerular injury?
Prerenal: decreased renal perfusion (often from hypovolemia) leading to a decrease in GFR; reversible. Intrarenal: intrinsic kidney damage; ATN most common due to ischemic/nephrotoxic injury. Postrenal: extrinsic/intrinsic obstruction of the urinary collection system.
What causes Intrarenal failure?
Intrinsic or intrarenal acute kidney injury (AKI) , which used to be called acute renal failure, occurs when direct damage to the kidneys causes a sudden loss in kidney function. The treatment of intrinsic acute kidney injury includes identifying and correcting the cause of the kidney injury.
What is Prerenal failure?
Prerenal acute kidney injury (AKI) , (which used to be called acute renal failure), occurs when a sudden reduction in blood flow to the kidney (renal hypoperfusion) causes a loss of kidney function. In prerenal acute kidney injury, there is nothing wrong with the kidney itself.
What is Intrarenal failure?
What is Postrenal failure?
Postrenal acute kidney injury , which used to be called acute renal failure, occurs when an obstruction in the urinary tract below the kidneys causes waste to build up in the kidneys . It is not as common as intrinsic acute kidney injury (AKI) or acute tubular necrosis (ATN).
What are the four phases of acute renal failure?
– High blood pressure – Anemia (a low number of red blood cells) – Bone disease
What are the five stages of kidney failure?
Follow the steps outlined in previous stages to take the best care and control of your health.
What are the 3 types of acute renal failure?
Reduction of the flow of blood to the kidneys
What causes prerenal acute kidney injury?
Acute tubular necrosis
