What is Intrarenal AKI?

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 the difference between Prerenal and Intrarenal?

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)

Is ATN an Intrarenal?

The tubule cell damage and cell death that characterize ATN usually result from an acute ischemic or toxic event. Nephrotoxic mechanisms of ATN include direct drug toxicity, intrarenal vasoconstriction, and intratubular obstruction (see Pathophysiology and Etiology).

What is a common cause of intrarenal acute renal failure?

The primary agents that cause prerenal acute renal failure are angiotensin-converting enzyme (ACE) inhibitors and nonsteroidal anti-inflammatory drugs (NSAIDs). The inhibition of ACE prevents the conversion of angiotensin I to angiotensin II, leading to decreased levels of angiotensin II.

How do I know if my AKI is Prerenal?

The excretion of urea occurs in the proximal tubules. In prerenal AKI, the FEUrea is less than 35 %, whereas, in intrinsic AKI, it is greater than 50%. The reported gold standard in differentiating prerenal from other causes of AKI is responsiveness to fluid administration.

What are the three classifications of acute kidney injury?

Etiology. The causes of acute kidney injury can be divided into three categories (Table 29 ): prerenal (caused by decreased renal perfusion, often because of volume depletion), intrinsic renal (caused by a process within the kidneys), and postrenal (caused by inadequate drainage of urine distal to the kidneys).

Is ATN the same as acute renal failure?

Acute tubular necrosis (ATN) is a kidney disorder involving damage to the tubule cells of the kidneys, which can lead to acute kidney failure. The tubules are tiny ducts in the kidneys that help filter the blood when it passes through the kidneys.

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.

Is Prerenal an ATN?

The two major causes of AKI that occur in the hospital are prerenal disease and acute tubular necrosis (ATN). Together, they account for approximately 65 to 75 percent of cases of AKI. (See 'Frequency of prerenal disease and acute tubular necrosis as a cause of AKI' below.)

How can you tell the difference between renal and Prerenal?

Response to fluid repletion is still regarded as the gold standard in the differentiation between prerenal and intrinsic AKI. Return of renal function to baseline within 24 to 72 hours is considered to indicate prerenal AKI, whereas persistent renal failure indicates intrinsic disease.

What does Prerenal mean?

Medical Definition of prerenal : occurring in the circulatory system before the kidney is reached the usual prerenal causes for transient renal insufficiency such as hypotonia and hypovolemia were excluded— Rudolf Pfab et al.

What is a Prerenal cause?

Causes of prerenal acute kidney injury include: Severe blood loss and low blood pressure related to major cardiac or abdominal surgery, severe infection (sepsis), or injury. Medicines that interfere with the blood supply to the kidneys.

How can you tell the difference between renal and prerenal azotemia?

Prerenal azotemia can usually be distinguished from renal azotemia by clinical signs (evidence of dehydration or hypovolemia), urinalysis (urine should be “adequately” concentrated i.e. > 1.030 in the dog, > 1.040 in the cat, > 1.025 in large animals; usually with no evidence of renal tubule dysfunction such as ...
