Renal Failure
A condition in which the kidneys fail toremove metabolic end-products from the bloodand regulate the fluid, electrolyte, and pH balanceof the extracellular fluids. The underlying causemay be renal disease, systemic disease, orurologic defects of nonrenal origin. Renal failurecan occur as an ACUTE or a CHRONIC disorder.

Acute Renal FailureAcute renal failure(ARF) now called Acute
Kidney Injury(AKI) represents a rapid decline in renalfunction or is defined as an abrupt (within 48 hours)reduction in kidney function based on an elevation inserum creatinine level, a reduction in urine output, theneed for renal replacement therapy (dialysis) in onsetand often is reversible if recognized early and treatedappropriately.
Acute renal failure is caused by differentconditions that produce an acute shutdown in renalfunction

Pathophysiology &Causes Of ARF/AKI
There are main THREE causes of ARF/AKI
1.Prerenal FailurePrerenal failure, the most common form of acute renal failure,is characterized by a marked decrease in renal blood flow. It isreversible if the cause of the decreased renal blood flow can beidentified and corrected before kidney damage occurs.

Causes of Prerenal:• Hypovolemia• Hemorrhage• Dehydration• Excessive loss of gastrointestinal tract fluids• Excessive loss of fluid due to burn injury• Decreased vascular filling• Anaphylactic shock• Septic shock• Heart failure and cardiogenic shock• Decreased renal perfusion due to vasoactive mediators, drugs, diagnostic

2. Intrinsic Renal Failure / Intra Renal
Intrinsic or intrarenal renal failure results fromconditions that cause damage to structures within thekidney— glomerular, tubular, or interstitial. The majorcauses of intrarenal failure are ischemia associated withPrerenal failure, toxic insult to the tubular structures ofthe nephron, and intratubular obstruction.

Pathophysiology & Causes Of ARF/AKI3. Post Renal FailurePost renal failure results from obstruction of urine outflow from thekidneys. The obstruction can occur in the ureter (i.e., calculi andstrictures), bladder (i.e., tumors or neurogenic bladder), or urethra (i.e.,prostatic hypertrophy).Post Renal• Bilateral ureteral obstruction• Bladder outlet obstruction• Calculi (stones)• Tumors• Benign prostatic hyperplasia• Strictures• Blood clots

Laboratory values stop rising and eventually decrease.Volume of urinary output may reach normal or elevated levels, at end of this stage maybegin to see improvement.

Management Of ARF/AKI
• If fluid resuscitation is required because of intravascular volumedepletion, isotonic solutions (e.g., normal saline) are preferred.
• A reasonable goal is a mean arterial pressure greater than 65 mmHg, which may require the use of vasopressors in patients withpersistent hypotension.
• Monitor and maintain electrolyte imbalances (e.g., hyperkalemia,hypophosphatemia, hypomagnesaemia, hypernatremia,hypernatremia, metabolic acidosis)

failure• Symptoms occur when 75% of function is lost but considered
chronic if 90-95% loss of function• Dialysis is necessary, accumulation or uremic toxins, which
