Renal failure occurs when the kidneys can no longer perform their essential functions adequately. The kidneys remove waste products, regulate fluid and electrolyte levels, help control blood pressure and contribute to red blood cell production.

Treatment depends on whether the kidney failure is acute or chronic, its underlying cause, the degree of kidney dysfunction and the patient's overall health. Some acute cases can improve when the underlying problem is treated promptly, while advanced chronic kidney failure may require kidney replacement therapy.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist and transplant physician, provides comprehensive evaluation and management for kidney failure, advanced chronic kidney disease, dialysis and kidney transplant related care.

What can cause renal failure?

Kidney failure can develop because of many different conditions.

Common causes include:

• Diabetes
• Long standing high blood pressure
• Severe dehydration
• Serious infections
• Acute kidney injury
• Kidney inflammation
• Urinary obstruction
• Kidney stones
• Certain medications or toxins
• Polycystic kidney disease
• Other chronic kidney disorders

Finding the underlying cause is an important first step because treatment varies considerably from one patient to another.

Acute and chronic renal failure

Acute kidney failure

Acute kidney failure develops over a relatively short period.

Potential causes include:

• Severe dehydration
• Infection
• Low blood pressure
• Certain medicines
• Urinary obstruction
• Severe illness

When the underlying cause is identified and treated promptly, kidney function may partially or substantially recover in some patients.

Chronic kidney failure

Chronic kidney failure develops over a prolonged period, usually as a result of progressive chronic kidney disease.

When kidney function becomes severely reduced, patients may eventually require dialysis or kidney transplantation.

Symptoms of renal failure

Symptoms can vary depending on how quickly kidney function has declined.

Possible symptoms include:

• Severe tiredness
• Swelling of the legs or feet
• Reduced urine output
• Changes in urination
• Nausea or vomiting
• Loss of appetite
• Persistent itching
• Muscle cramps
• Difficulty concentrating
• Breathlessness
• Sleep problems
• Confusion in severe cases

Some people with chronic kidney disease may have very few symptoms until the disease becomes advanced.

How renal failure is diagnosed

A nephrologist may use several investigations to determine kidney function and identify the underlying problem.

Tests may include:

• Serum creatinine
• eGFR
• Blood urea
• Electrolytes
• Complete blood count
• Urine examination
• Urine protein or albumin testing
• Kidney ultrasound
• Additional imaging when required

The patient's medical history and previous kidney function results are also important.

What is the treatment for renal failure?

There is no single treatment that applies to every case.

Treatment may involve one or more of the following approaches.

Treating the underlying cause

If kidney failure is caused by dehydration, infection, obstruction, medication related injury or another reversible problem, treating that cause may help improve kidney function.

Managing blood pressure

High blood pressure can both contribute to kidney damage and worsen existing kidney disease.

Appropriate blood pressure management is an important part of long term kidney care.

Managing diabetes

For patients with diabetic kidney disease, controlling blood glucose and other cardiovascular risk factors is an important component of treatment.

Correcting electrolyte abnormalities

Advanced kidney dysfunction can cause abnormalities in potassium, sodium and acid base balance.

These problems may require dietary measures, medication or hospital based treatment depending on severity.

Managing fluid overload

When damaged kidneys cannot remove enough fluid, swelling and breathlessness can occur.

Treatment may include dietary sodium restriction, prescribed medicines and, in severe cases, dialysis.

Renal failure treatment with dialysis

Dialysis is a form of kidney replacement therapy that helps remove waste and excess fluid when the kidneys cannot adequately perform these functions.

Two major forms include:

Hemodialysis

Blood is circulated through a dialysis machine where waste products and excess fluid are removed.

Treatment schedules vary according to the patient's medical needs.

Peritoneal dialysis

Peritoneal dialysis uses the lining of the abdomen as a natural filtering membrane. A dialysis solution is introduced into the abdominal cavity and later drained.

The suitability of each method depends on medical, lifestyle and personal considerations.

When is dialysis necessary?

Dialysis is not started solely because of one creatinine value.

A nephrologist considers factors such as:

• Symptoms of advanced kidney failure
• Fluid overload
• Persistent electrolyte abnormalities
• Acid base disturbances
• Difficulty controlling complications
• Overall kidney function
• General health and nutritional status

The decision should be individualized.

Kidney transplant as a treatment option

For selected patients with irreversible advanced kidney failure, kidney transplantation may provide an alternative to long term dialysis.

Transplant evaluation can involve assessment of:

• Overall health
• Heart and blood vessel health
• Infection status
• Blood group compatibility
• Potential living donors
• Suitability for transplantation

A transplant physician and nephrology team can guide patients through the evaluation process.

Renal failure diet

Dietary requirements depend on kidney function and treatment.

A renal diet may involve individualized guidance regarding:

• Sodium
• Protein
• Potassium
• Phosphorus
• Fluid intake

Patients receiving dialysis may have different nutritional requirements from patients who are not yet on dialysis.

It is important not to follow a generic kidney diet without professional advice.

Can renal failure be reversed?

The possibility of recovery depends on the type and cause of kidney failure.

Some cases of acute kidney failure can improve significantly when the underlying cause is treated.

Advanced chronic kidney failure is generally not reversible, but appropriate treatment can help manage symptoms, reduce complications and provide kidney replacement therapy when required.

Protecting remaining kidney function

For patients who still have meaningful kidney function, the treatment plan may focus on slowing further decline.

Helpful measures may include:

• Controlling blood pressure
• Managing diabetes
• Following prescribed medications
• Avoiding unnecessary painkillers
• Avoiding smoking
• Maintaining appropriate physical activity
• Following an individualized diet
• Attending regular nephrology appointments
• Monitoring kidney function

Fluid intake should be based on individual medical advice.

When renal failure requires urgent attention

Seek urgent medical care if a person with kidney disease develops:

• Severe breathlessness
• Very little or no urine
• Severe swelling
• Persistent vomiting
• Confusion
• Chest discomfort
• Severe weakness
• Significant changes in consciousness

These symptoms may indicate serious complications.

Why specialist nephrology care is important

Renal failure can involve multiple interconnected problems. A nephrologist can evaluate kidney function while also managing blood pressure, diabetes, anemia, electrolytes, fluid balance and other complications.

Dr. Sandip Prabhakar Bhurke provides specialized care involving:

• Renal failure evaluation
• Acute kidney injury management
• Advanced CKD care
• Dialysis planning and management
• Kidney stone and obstruction related care
• Diabetic kidney disease management
• Kidney transplant evaluation
• Long term kidney health monitoring

At Prabhakar Bhurke Clinic, treatment is tailored according to the patient's kidney function, underlying condition, symptoms, investigations and overall health.

Take the next step in kidney care

Renal failure is a serious condition, but treatment options have advanced significantly. Early evaluation can help identify reversible causes, while appropriate long term management can control complications and help patients prepare for dialysis or transplantation when necessary.

If you or a family member has declining kidney function, elevated creatinine, reduced urine output or a diagnosis of advanced kidney disease, consultation with a qualified nephrologist can help determine the most appropriate treatment pathway.
