Introduction
Acute Renal Failure (ARF), now more commonly known as Acute Kidney Injury (AKI), is a condition in which the kidneys suddenly lose their ability to filter waste products and maintain the body's fluid and electrolyte balance. In children, acute renal failure is a medical emergency that requires prompt diagnosis and treatment to prevent permanent kidney damage and other serious complications.
Unlike chronic kidney disease, acute kidney injury develops over hours or days and may often be reversible if treated early. The condition can affect infants, children, and adolescents and may occur due to dehydration, severe infections, medications, urinary tract obstruction, or other medical conditions.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, dialysis guidance, and long-term kidney care while coordinating with pediatric specialists whenever necessary.
What Is Acute Renal Failure in Children?
Acute renal failure occurs when the kidneys suddenly become unable to:
-
Filter waste products from the blood
-
Remove excess fluid
-
Maintain electrolyte balance
-
Regulate acid-base balance
-
Produce adequate urine
Without timely treatment, waste products accumulate in the bloodstream, affecting multiple organs.
Symptoms of Acute Renal Failure in Children
Symptoms vary depending on the severity of kidney injury.
Common symptoms include:
-
Reduced urine output
-
Swelling of the face, hands, feet, or legs
-
Puffiness around the eyes
-
Fatigue
-
Weakness
-
Loss of appetite
-
Nausea and vomiting
-
Fever (if infection is present)
-
High blood pressure
-
Difficulty breathing due to fluid overload
-
Blood in the urine
-
Dark-colored urine
-
Irritability in infants and young children
-
Confusion or drowsiness in severe cases
Parents should seek immediate medical attention if urine output decreases significantly or if swelling develops suddenly.
Causes of Acute Renal Failure in Children
Several conditions can lead to sudden kidney injury.
Severe Dehydration
Loss of body fluids due to:
-
Vomiting
-
Diarrhea
-
High fever
-
Poor fluid intake
can reduce blood flow to the kidneys.
Severe Infections
Serious bacterial or viral infections may damage the kidneys or reduce blood circulation to them.
Kidney Infections
Untreated kidney infections (pyelonephritis) can impair kidney function.
Urinary Tract Obstruction
Blockage caused by:
-
Kidney stones
-
Congenital urinary abnormalities
-
Posterior urethral valves
-
Tumors (rare)
may prevent urine drainage.
Certain Medications
Some medicines may affect kidney function, including:
-
Certain antibiotics
-
Non-steroidal anti-inflammatory drugs (NSAIDs)
-
Some chemotherapy drugs
These medicines should always be used under medical supervision.
Glomerulonephritis
Inflammation of the kidney's filtering units may cause sudden kidney injury.
Hemolytic Uremic Syndrome (HUS)
HUS is an important cause of acute kidney injury in children and often follows certain bacterial infections.
Risk Factors
Children may have a higher risk if they have:
-
Severe dehydration
-
Recurrent urinary tract infections
-
Congenital kidney abnormalities
-
Diabetes
-
Autoimmune disorders
-
Previous kidney disease
-
Serious infections
Early diagnosis is essential in high-risk children.
Possible Complications
Without prompt treatment, acute renal failure may lead to:
-
Electrolyte imbalance
-
Fluid overload
-
High blood pressure
-
Severe infection
-
Permanent kidney damage
-
Chronic kidney disease
-
Dialysis requirement
-
Multi-organ complications
Early treatment significantly improves recovery.
How Is Acute Renal Failure Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a thorough kidney evaluation.
Medical History and Physical Examination
The doctor evaluates:
-
Urine output
-
Fluid intake
-
Medical history
-
Current medications
-
Previous kidney problems
-
Signs of dehydration or swelling
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Complete Blood Count (CBC)
These tests help determine the severity of kidney injury.
Urine Tests
Urine investigations may include:
-
Routine urinalysis
-
Urine microscopy
-
Urine culture
-
Protein estimation
These tests help identify infection, blood, protein, or other abnormalities.
Imaging Studies
Imaging may include:
-
Kidney Ultrasound
-
CT Scan when clinically indicated
These tests help detect urinary obstruction or structural abnormalities.
Treatment for Acute Renal Failure in Children
Treatment depends on the underlying cause and severity.
Fluid Management
Careful correction of dehydration or fluid overload is essential.
Fluid therapy is individualized according to the child's condition.
Treat the Underlying Cause
Treatment may include:
-
Antibiotics for infections
-
Relief of urinary obstruction
-
Treatment of autoimmune diseases
-
Stopping medications affecting kidney function
Electrolyte Correction
Electrolyte abnormalities are carefully monitored and treated to prevent complications.
Blood Pressure Control
High blood pressure is managed using appropriate medications.
Dialysis
Temporary dialysis may be required if:
-
Kidney function declines severely
-
Fluid overload develops
-
Electrolyte imbalance becomes dangerous
-
Waste products accumulate significantly
Many children recover kidney function after temporary dialysis.
Recovery After Acute Kidney Injury
Many children recover completely when treatment begins early.
Recovery depends on:
-
Cause of kidney injury
-
Severity of illness
-
Speed of diagnosis
-
Overall health
-
Response to treatment
Regular follow-up is important to monitor kidney function after recovery.
How Can Acute Kidney Injury Be Prevented?
Parents can help reduce the risk by:
-
Ensuring adequate hydration
-
Treating diarrhea and vomiting promptly
-
Seeking early treatment for urinary infections
-
Avoiding unnecessary medications without medical advice
-
Managing chronic medical conditions
-
Attending regular follow-up appointments if kidney disease is present
Preventive care supports long-term kidney health.
