The kidneys perform essential functions that keep the body's internal environment balanced. They remove waste products, regulate fluid levels, help maintain electrolyte balance and contribute to blood-pressure regulation and other important processes.

When kidney function becomes severely impaired, waste products and excess fluid can accumulate in the body. Depending on the cause and severity, treatment may include medicines, dietary management, correction of reversible problems and, in advanced cases, kidney replacement therapy such as dialysis or kidney transplantation.

Kidney failure and dialysis treatment are closely related, but dialysis is not automatically required whenever kidney function is reduced.

The decision depends on the severity of kidney dysfunction, symptoms, complications, urine output, electrolyte abnormalities, fluid balance and the patient's overall health.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for kidney failure and dialysis-related conditions.

What Is Kidney Failure?

Kidney failure occurs when the kidneys can no longer adequately perform their essential functions.

It may develop:

• Suddenly, as part of acute kidney injury

• Gradually, as advanced chronic kidney disease progresses

Kidney failure can result from several conditions, including:

• Long-standing diabetes

• High blood pressure

• Glomerular diseases

• Polycystic kidney disease

• Recurrent or severe kidney infections

• Urinary obstruction

• Certain medications or toxins

• Severe acute illnesses

• Other chronic kidney disorders

Treatment depends on whether kidney dysfunction is reversible and how much kidney function remains.

Does Every Patient With Kidney Disease Need Dialysis?

No.

Many people with chronic kidney disease can be managed without dialysis for years.

Even severe acute kidney injury may sometimes improve after treatment of the underlying problem.

Dialysis is considered when the kidneys cannot adequately maintain the body's internal balance and complications cannot be controlled sufficiently with medical treatment.

Therefore, a creatinine value alone does not determine whether dialysis is necessary.

When Is Dialysis Recommended?

A nephrologist may recommend dialysis when kidney failure results in serious or persistent complications such as:

• Significant fluid overload

• Severe or persistent potassium abnormalities

• Severe metabolic acidosis

• Uremic symptoms or complications

• Certain toxin exposures

• Severe symptoms related to kidney failure

• Inability to control complications through conservative treatment

The timing is individualized.

A patient with a particular creatinine level may not require immediate dialysis, while another patient with a different clinical situation may need urgent kidney replacement therapy.

Kidney Failure Symptoms That May Occur

Kidney failure can cause symptoms because waste products, fluid and electrolytes accumulate.

Possible symptoms include:

• Persistent tiredness

• Poor appetite

• Nausea

• Vomiting

• Itching

• Swelling of the legs or face

• Breathlessness

• Muscle cramps

• Changes in urine output

• Difficulty concentrating

• Sleep disturbances

Some patients may have few symptoms despite significant kidney-function impairment.

Regular medical monitoring is therefore important for people with advanced kidney disease.

Kidney Failure and CKD Creatinine Levels

People often search for CKD creatinine levels to determine how close they are to kidney failure.

Creatinine is useful for assessing kidney filtration, but there is no single creatinine number that automatically means kidney failure or dialysis is required.

Doctors may consider:

• Serum creatinine

• eGFR

• Rate of change in kidney function

• Urine albumin or protein

• Potassium

• Bicarbonate

• Blood urea

• Fluid status

• Symptoms

• Blood pressure

• Overall health

Trends over time can be more informative than one isolated laboratory result.

Dialysis for Acute Kidney Injury

Acute kidney injury (AKI) develops over a short period and can have potentially reversible causes.

Examples include:

• Severe dehydration

• Serious infection

• Low blood pressure

• Certain medications

• Urinary obstruction

• Major surgery or critical illness

• Severe inflammation affecting the kidneys

Some patients with severe AKI require temporary dialysis.

If kidney function recovers sufficiently, dialysis may eventually be discontinued.

This differs from advanced chronic kidney failure, where long-term kidney replacement therapy may be necessary.

Main Types of Dialysis Treatment

There are two major forms of dialysis used for kidney replacement therapy.

Hemodialysis

Hemodialysis uses a dialysis machine and a special filter called a dialyzer.

Blood travels from the body through the dialysis circuit, passes through the dialyzer, and returns after waste products and excess fluid have been removed.

Hemodialysis can be performed in a dialysis center or, for appropriately selected patients, through home-based programs where available and suitable.

Peritoneal Dialysis

Peritoneal dialysis uses the lining of the abdomen, called the peritoneum, as a natural filtering membrane.

Dialysis fluid is introduced into the abdominal cavity through a catheter.

Waste products and excess fluid move into the dialysis solution, which is subsequently drained and replaced.

Peritoneal dialysis can be performed using different schedules and techniques depending on the patient's treatment plan.

How Does Hemodialysis Work?

A typical hemodialysis treatment involves:

1. Connecting the patient to a dialysis machine through appropriate vascular access.

2. Circulating blood through the dialyzer.

3. Removing waste products and excess fluid.

4. Returning filtered blood to the patient.

5. Monitoring blood pressure and other clinical parameters throughout treatment.

Treatment duration and frequency are individualized according to the patient's kidney function, body size, residual kidney function, fluid status and overall medical needs.

What Is Dialysis Access?

Patients receiving hemodialysis require a way for blood to safely leave and return to the body.

Common forms of vascular access include:

Arteriovenous Fistula

An AV fistula connects an artery to a vein, usually in the arm.

It is often preferred for long-term hemodialysis because of its durability and lower infection risk compared with some other access types.

Arteriovenous Graft

A graft uses a synthetic or biological material to connect an artery and vein.

It may be considered when a suitable fistula cannot be created.

Dialysis Catheter

A catheter can provide temporary or, in selected circumstances, longer-term vascular access.

Catheters carry a higher risk of infection and other complications, so access planning is important.

What Happens During Peritoneal Dialysis?

Peritoneal dialysis generally follows a cycle of:

• Filling the abdomen with dialysis fluid

• Allowing the solution to remain for a prescribed period

• Draining the used solution

• Replacing it with fresh dialysis fluid

The schedule depends on the selected peritoneal dialysis method and the patient's treatment requirements.

Patients receive training on catheter care, infection prevention and the dialysis procedure.

How Does a Doctor Decide Which Dialysis Type Is Better?

There is no universally best dialysis method for every patient.

The choice may depend on:

• Medical condition

• Age and functional status

• Residual kidney function

• Home environment

• Lifestyle

• Ability to perform treatment

• Previous abdominal surgery

• Vascular access options

• Patient preference

• Availability of support

A nephrologist can explain the advantages and limitations of each option.

Can Kidney Failure Be Treated Without Dialysis?

In some circumstances, yes.

Before starting long-term dialysis, doctors identify potentially reversible factors and manage complications where possible.

Treatment may involve:

• Controlling blood pressure

• Managing diabetes

• Treating infections

• Relieving urinary obstruction

• Adjusting kidney-affecting medicines

• Managing fluid and electrolyte problems

• Individualized dietary management

• Treating anemia and mineral abnormalities when appropriate

However, when kidney failure causes complications that cannot be controlled adequately, dialysis or another form of kidney replacement therapy may become necessary.

Is Dialysis Permanent?

Not always.

In acute kidney injury, dialysis may be temporary if kidney function recovers.

For advanced chronic kidney failure, dialysis may become a long-term treatment unless the patient receives a successful kidney transplant or another suitable treatment changes the situation.

The expected duration depends on the underlying disease and the degree of kidney recovery.

Does Dialysis Cure Kidney Failure?

Dialysis does not repair permanently damaged kidneys.

Instead, it performs some of the functions that failing kidneys can no longer perform, including removing waste and excess fluid.

In acute kidney injury, dialysis can provide support while the kidneys recover.

In permanent kidney failure, dialysis may be required as an ongoing form of kidney replacement therapy.

Kidney Transplantation as an Alternative

For appropriately selected patients with advanced kidney failure, kidney transplantation can provide functioning kidney tissue from a suitable donor.

A transplant may offer greater independence from dialysis for eligible patients, but it involves surgery, lifelong medical follow-up and anti-rejection medicines.

Not every patient is a suitable transplant candidate, so evaluation by a transplant team is necessary.

Preparing for Dialysis

If kidney function is progressively declining, early preparation can make the transition to dialysis safer.

Preparation may include:

• Learning about dialysis options

• Discussing hemodialysis and peritoneal dialysis

• Planning vascular access

• Assessing transplant eligibility

• Reviewing medications

• Managing blood pressure and diabetes

• Addressing nutritional requirements

• Planning for home or center-based treatment

Preparing for dialysis does not necessarily mean dialysis must start immediately.

What Tests Are Monitored During Kidney Failure?

Depending on the patient, doctors may monitor:

Blood Tests

• Creatinine

• eGFR

• Blood urea

• Potassium

• Sodium

• Bicarbonate

• Calcium

• Phosphorus

• Hemoglobin

Urine Tests

• Urine volume

• Protein

• Albumin

• Blood

• Other abnormalities

Clinical Measurements

• Blood pressure

• Body weight

• Fluid retention

• Swelling

• Breathing status

• Nutritional status

These measurements help the nephrologist assess disease progression and treatment needs.

Diet During Kidney Failure and Dialysis

Dietary requirements vary significantly between people with kidney failure.

Depending on kidney function and dialysis treatment, a healthcare professional may recommend adjustments to:

• Sodium

• Potassium

• Phosphorus

• Protein

• Fluid intake

People on dialysis should not follow an extreme diet without guidance from their nephrologist or renal dietitian.

Dietary recommendations can change depending on laboratory results and the type of dialysis being received.

Common Dialysis-Related Complications

Dialysis is an established life-supporting treatment, but complications can occur.

Possible issues include:

• Low blood pressure during hemodialysis

• Muscle cramps

• Fatigue after treatment

• Vascular-access problems

• Catheter-related infection

• Peritoneal dialysis-related infection

• Fluid and electrolyte changes

Regular monitoring and proper access care can help reduce risks.

Patients should report unusual symptoms or problems with their dialysis access promptly.

When Is Kidney Failure an Emergency?

Seek urgent medical attention for symptoms such as:

• Severe breathlessness

• Chest pain

• Confusion

• Very little or no urine

• Severe swelling

• Persistent vomiting

• Severe weakness

• Fainting

• Rapidly worsening symptoms

These symptoms may indicate serious complications requiring immediate assessment.

Frequently Asked Questions

At what creatinine level is dialysis required?

There is no universal creatinine threshold that automatically requires dialysis. The decision depends on symptoms, complications, kidney function, fluid status, electrolyte abnormalities and the underlying cause.

Can kidney failure improve without dialysis?

Some cases of acute kidney injury can improve when the underlying cause is treated. Advanced irreversible chronic kidney failure is different and may require long-term kidney replacement therapy.

Is dialysis the final stage of kidney treatment?

Dialysis is one form of kidney replacement therapy. For suitable patients, kidney transplantation may provide an alternative to long-term dialysis.

How long can someone live on dialysis?

Survival varies substantially according to age, underlying disease, cardiovascular health, nutrition, complications, dialysis adequacy and other individual factors. A nephrologist can provide more meaningful information based on the patient's specific condition.

Can dialysis be stopped?

Dialysis may sometimes be discontinued when it was started for reversible acute kidney injury and kidney function recovers sufficiently. It should never be stopped without assessment and direction from the treating medical team.

Is hemodialysis better than peritoneal dialysis?

Neither is universally better. Both are established treatment options, and the appropriate choice depends on medical factors, lifestyle, home circumstances and patient preference.

Conclusion

Kidney failure and dialysis treatment require individualized medical planning. Dialysis may become necessary when severely reduced kidney function leads to complications that cannot be adequately controlled with medical treatment.

Hemodialysis and peritoneal dialysis can replace important kidney functions by removing waste products and excess fluid. For some patients with acute kidney injury, dialysis may only be temporary. For advanced chronic kidney failure, long-term dialysis or kidney transplantation may be considered.

Early nephrology care can help patients understand treatment options, prepare for kidney replacement therapy when needed and manage complications of advanced kidney disease.
