Introduction
Acute renal failure, now more commonly called Acute Kidney Injury (AKI), is a sudden decline in kidney function that develops over hours or days. When the kidneys stop filtering waste products and excess fluid effectively, harmful substances can build up in the body, leading to serious health complications.
Although many patients with AKI recover with prompt treatment, some individuals develop severe kidney dysfunction and may require dialysis as a temporary life-saving treatment until the kidneys recover.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive diagnosis, emergency kidney care, dialysis management, and long-term follow-up for patients with acute kidney injury and other kidney disorders.
What Is Acute Renal Failure?
Acute renal failure (Acute Kidney Injury) is the sudden loss of the kidneys' ability to:
-
Remove waste products
-
Eliminate excess fluid
-
Maintain electrolyte balance
-
Regulate acid-base balance
-
Support overall body function
Unlike chronic kidney disease, AKI develops rapidly and often requires urgent medical attention.
What Is Dialysis?
Dialysis is a medical treatment that performs some of the functions normally carried out by healthy kidneys.
Dialysis helps:
-
Remove waste products from the blood
-
Eliminate excess fluid
-
Correct electrolyte imbalances
-
Improve acid-base balance
-
Support the body while the kidneys recover
In acute kidney injury, dialysis is often temporary, although some patients may require ongoing treatment depending on the extent of kidney damage.
When Is Dialysis Needed in Acute Renal Failure?
Not every patient with acute kidney injury requires dialysis.
Your nephrologist may recommend dialysis when AKI causes:
-
Severe fluid overload
-
High potassium levels that cannot be controlled with medication
-
Severe metabolic acidosis
-
Dangerous build-up of waste products (uremia)
-
Reduced urine output causing complications
-
Symptoms affecting the heart, lungs, or brain
The decision is based on your overall condition, laboratory results, symptoms, and response to medical treatment.
Causes of Acute Kidney Injury
Common causes include:
-
Severe dehydration
-
Major infections (sepsis)
-
Low blood pressure
-
Heart failure
-
Severe blood loss
-
Certain medications
-
Contrast dye used during imaging tests
-
Urinary tract obstruction
-
Kidney inflammation
-
Acute tubular necrosis
-
Autoimmune kidney diseases
Identifying and treating the underlying cause is essential for recovery.
Symptoms of Acute Renal Failure
Symptoms may develop suddenly and include:
-
Reduced urine output
-
Swelling of the legs, ankles, or face
-
Shortness of breath
-
Fatigue
-
Weakness
-
Nausea and vomiting
-
Loss of appetite
-
Confusion
-
Difficulty concentrating
-
High blood pressure
-
Chest discomfort in severe cases
Some patients may have only mild symptoms despite significant kidney dysfunction.
Signs That Dialysis May Be Required
Dialysis may be considered if a patient develops:
-
Persistent high potassium levels
-
Severe swelling due to fluid overload
-
Difficulty breathing from excess fluid
-
Severe metabolic acidosis
-
Uremic symptoms such as confusion or drowsiness
-
Persistent decrease in urine output
-
Rapidly worsening kidney function
The decision is individualized and made by a nephrologist after careful evaluation.
Types of Dialysis Used in Acute Kidney Injury
Depending on the patient's condition, different dialysis methods may be used.
Hemodialysis
Hemodialysis removes waste products and excess fluid through a dialysis machine.
It is commonly used in patients with acute kidney injury.
Continuous Renal Replacement Therapy (CRRT)
CRRT is used mainly for critically ill patients in intensive care units (ICUs).
It provides slow, continuous blood purification over an extended period.
Peritoneal Dialysis
In selected situations, peritoneal dialysis may be considered, although it is less commonly used for acute kidney injury.
How Is Acute Renal Failure Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a complete kidney evaluation.
Medical History and Physical Examination
Your doctor will review:
-
Symptoms
-
Medical history
-
Current medications
-
Fluid status
-
Blood pressure
-
Recent illnesses or surgeries
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Complete Blood Count (CBC)
-
Acid-base status
These tests help determine the severity of kidney injury.
Urine Tests
Urine investigations may include:
-
Urinalysis
-
Urine Microscopy
-
Urine Protein Testing
These tests help identify the underlying cause of kidney injury.
Imaging Studies
Imaging may include:
-
Kidney Ultrasound
-
CT Scan when clinically indicated
These studies help identify urinary obstruction or structural abnormalities.
Treatment of Acute Renal Failure
Treatment focuses on addressing the underlying cause while supporting kidney function.
Treating the Underlying Cause
Depending on the diagnosis, treatment may involve:
-
Treating infections
-
Correcting dehydration
-
Improving blood pressure
-
Relieving urinary obstruction
-
Stopping medications that may damage the kidneys
Fluid Management
Your nephrologist carefully balances fluid intake and removal based on your condition.
Electrolyte Management
Treatment may be required to correct abnormal potassium, sodium, calcium, or acid-base levels.
Medications
Medicines may be prescribed to:
-
Control blood pressure
-
Treat infection
-
Manage electrolyte abnormalities
-
Support overall recovery
Dialysis
If complications become severe, dialysis helps support the body while the kidneys recover.
Many patients require dialysis only temporarily until kidney function improves.
Recovery After Acute Kidney Injury
Recovery depends on:
-
The underlying cause
-
Severity of kidney injury
-
Age
-
Overall health
-
Timeliness of treatment
Some patients recover completely, while others may develop chronic kidney disease or require long-term follow-up.
Regular monitoring is essential even after recovery.
Can Acute Kidney Injury Be Prevented?
Although not every case is preventable, you can reduce your risk by:
-
Staying adequately hydrated
-
Managing diabetes and blood pressure
-
Avoiding unnecessary use of NSAID painkillers
-
Treating infections promptly
-
Following medical advice during severe illnesses
-
Having regular kidney function tests if you are at high risk

Frequently Asked Questions (FAQs)
Does every patient with acute renal failure need dialysis?
No. Many patients recover with medications and treatment of the underlying cause. Dialysis is recommended only when serious complications develop or kidney function becomes severely impaired.
Is dialysis permanent in acute kidney injury?
Not always. In many cases, dialysis is temporary and can be stopped once kidney function improves sufficiently.
Can kidneys recover after dialysis for acute kidney injury?
Yes. Many patients regain significant kidney function after the underlying cause is treated. Recovery varies depending on the severity of the injury and overall health.
How long does dialysis continue in acute kidney injury?
The duration varies from patient to patient. Some individuals require only a few dialysis sessions, while others may need treatment for weeks until kidney function recovers.
Conclusion
Acute renal failure (Acute Kidney Injury) is a serious condition that requires prompt diagnosis and treatment. Although many patients recover with appropriate medical care, some develop complications that make dialysis necessary as a temporary life-saving treatment.
