Introduction
Acute renal failure, now commonly called Acute Kidney Injury (AKI), is a sudden decline in kidney function that occurs within hours or days. It is a medical emergency that requires prompt diagnosis and treatment. Understanding the types of acute renal failure helps in identifying the cause and starting appropriate therapy early. At Prabhakar Bhurke Clinic, patients receive advanced care from a super specialist nephrologist to ensure the best possible outcomes.
What Is Acute Renal Failure?
Acute renal failure occurs when the kidneys suddenly lose their ability to filter waste products, regulate fluids, and maintain electrolyte balance. Without timely treatment, it can lead to serious complications or progress to chronic kidney disease.
Main Types of Acute Renal Failure
Acute renal failure is classified into three main types based on the underlying cause:
1. Pre-Renal Acute Renal Failure
Cause
Occurs due to reduced blood flow to the kidneys, without direct kidney damage.
Common Reasons
-
Severe dehydration
-
Blood loss or shock
-
Heart failure
-
Low blood pressure
-
Severe infections (sepsis)
Symptoms
-
Decreased urine output
-
Dizziness
-
Low blood pressure
-
Rapid pulse
Treatment
-
Fluid replacement
-
Blood pressure stabilization
-
Treating the underlying cause
Early treatment can often reverse kidney damage completely.
2. Intrinsic (Renal) Acute Renal Failure
Cause
Occurs due to direct damage to kidney tissue.
Common Reasons
-
Acute tubular necrosis
-
Glomerulonephritis
-
Severe infections
-
Drug toxicity (painkillers, antibiotics, contrast dye)
-
Autoimmune diseases
Symptoms
-
Swelling of legs or face
-
Blood or protein in urine
-
Fatigue and weakness
-
Rising creatinine levels
Treatment
-
Stopping harmful medications
-
Treating infections or inflammation
-
Immunosuppressive therapy (if needed)
-
Dialysis in severe cases
3. Post-Renal Acute Renal Failure
Cause
Occurs due to blockage of urine flow, leading to pressure buildup in the kidneys.
Common Reasons
-
Kidney stones
-
Enlarged prostate
-
Tumors
-
Urethral strictures
Symptoms
-
Difficulty urinating
-
Pain in lower abdomen or back
-
Reduced or absent urine output
Treatment
-
Removing the obstruction
-
Catheterization or surgical intervention
-
Treating underlying conditions
Timely relief of obstruction often restores kidney function.
Diagnosis of Acute Renal Failure
At Prabhakar Bhurke Clinic, diagnosis includes:
-
Blood tests (creatinine, urea, electrolytes)
-
Urine examination
-
Ultrasound or CT scan
-
Monitoring urine output
