The fields of nephrology and dialysis are closely connected in the management of patients with advanced kidney disease. Nephrology focuses on the prevention, diagnosis, and treatment of kidney disorders, while dialysis is one form of kidney replacement therapy used when the kidneys can no longer adequately perform essential functions.
The kidneys normally remove waste products and excess fluid from the blood while helping regulate electrolytes, acid-base balance, blood pressure, and other important processes. When kidney function becomes severely impaired, waste products and fluid can accumulate and cause serious complications.
Dialysis can replace some of the filtering functions of the kidneys, but it does not cure every cause of kidney failure. The decision to start dialysis depends on the patient's overall condition, symptoms, complications, kidney function, and treatment goals.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist and transplant physician, provides comprehensive kidney care, dialysis planning, dialysis management, chronic kidney disease treatment, and kidney transplant evaluation.
What Is Nephrology?
Nephrology is the medical specialty focused on diseases and disorders affecting the kidneys.
A nephrologist diagnoses and manages conditions such as:
-
Chronic Kidney Disease (CKD)
-
Acute Kidney Injury (AKI)
-
Kidney failure
-
High blood pressure related to kidney disease
-
Diabetic kidney disease
-
Glomerulonephritis
-
Electrolyte abnormalities
-
Acid-base disorders
-
Protein or blood in the urine
-
Kidney-related complications of systemic diseases
-
Dialysis-related medical problems
-
Kidney transplant-related kidney care
Nephrology care can begin well before dialysis becomes necessary.
What Is Dialysis?
Dialysis is a kidney replacement therapy that removes some waste products and excess fluid from the body when the kidneys are unable to perform these functions adequately.
Dialysis can help manage:
-
Waste accumulation
-
Excess fluid
-
Certain electrolyte abnormalities
-
Some acid-base disturbances
There are two major forms of dialysis:
-
Hemodialysis
-
Peritoneal dialysis
The appropriate option depends on the patient's medical condition, lifestyle, home environment, vascular access or catheter considerations, and personal preferences.
When Is Dialysis Needed?
Dialysis is generally considered when kidney failure results in complications that cannot be adequately controlled with medical treatment.
Possible reasons include:
-
Severe fluid overload
-
Persistent high potassium despite treatment
-
Significant metabolic acidosis
-
Symptoms caused by accumulation of waste products
-
Certain complications of kidney failure
-
Some cases of severe acute kidney injury
Importantly, dialysis is not started based on creatinine or eGFR alone.
A patient with a particular eGFR may or may not need dialysis depending on symptoms, complications, nutrition, fluid balance, electrolyte levels, and overall clinical condition.
Your nephrologist determines when kidney replacement therapy is appropriate.
Hemodialysis
Hemodialysis uses a dialysis machine and a special filter called a dialyzer to remove waste products and excess fluid from the blood.
Blood travels from the body to the dialysis machine, passes through the dialyzer, and is then returned to the patient.
Vascular Access for Hemodialysis
Reliable access to the bloodstream is necessary.
Common types include:
-
Arteriovenous fistula
-
Arteriovenous graft
-
Central venous catheter in selected situations
An arteriovenous fistula is often preferred for long-term hemodialysis when appropriate because of its durability and lower infection risk compared with long-term catheter use.
What Happens During Hemodialysis?
During a typical session:
-
Blood is removed through the vascular access.
-
Blood passes through the dialyzer.
-
Waste products and excess fluid are removed.
-
The filtered blood returns to the body.
-
Blood pressure and other parameters are monitored.
The duration and frequency of dialysis sessions are individualized.
Many patients receive hemodialysis several times per week, although schedules vary depending on the treatment setting and medical needs.
Peritoneal Dialysis
Peritoneal dialysis uses the peritoneal membrane inside the abdomen as a natural filtering membrane.
A soft catheter is placed into the abdominal cavity. Dialysis fluid is introduced through the catheter and later drained.
Waste products and excess fluid move from the blood across the peritoneal membrane into the dialysis fluid.
Peritoneal dialysis can generally be performed at home after appropriate training.
Types of Peritoneal Dialysis
Two commonly used approaches are:
Continuous Ambulatory Peritoneal Dialysis
CAPD involves manual exchanges of dialysis fluid throughout the day.
Automated Peritoneal Dialysis
APD uses a machine, usually during the night, to perform exchanges automatically.
The choice depends on medical suitability, lifestyle, home circumstances, and patient preference.
Hemodialysis vs Peritoneal Dialysis
Both methods can provide effective kidney replacement therapy, but they work differently.
| Feature | Hemodialysis | Peritoneal Dialysis |
|---|---|---|
| Filtering method | Dialyzer | Peritoneal membrane |
| Blood access | Vascular access required | Abdominal catheter |
| Typical setting | Dialysis center or home in selected cases | Usually home |
| Schedule | Often intermittent | Usually daily or automated |
| Major concerns | Blood pressure changes, access problems | Peritonitis, catheter problems |
| Lifestyle | Depends on dialysis schedule | Can offer greater home-based flexibility for some patients |
There is no universally “best” dialysis method. The choice should be individualized.
Benefits of Dialysis
Dialysis can help patients with advanced kidney failure by:
-
Removing excess fluid
-
Removing waste products
-
Helping control certain electrolyte abnormalities
-
Correcting some acid-base disturbances
-
Relieving symptoms related to kidney failure
-
Supporting patients while they await kidney transplantation when appropriate
Dialysis is an important treatment, but ongoing nephrology care remains essential.
Possible Risks and Complications of Hemodialysis
Some patients may experience:
-
Low blood pressure
-
Muscle cramps
-
Fatigue after treatment
-
Vascular access infection
-
Vascular access clotting or malfunction
-
Bleeding related to access
-
Anemia
-
Electrolyte changes
Regular monitoring helps identify and manage complications.
Possible Complications of Peritoneal Dialysis
Potential complications include:
-
Peritonitis
-
Catheter-site infection
-
Abdominal discomfort
-
Hernia
-
Dialysis fluid leakage
-
Problems with catheter drainage
Patients receiving peritoneal dialysis are taught how to recognize warning signs and maintain appropriate catheter care.
Nephrologist's Role in Dialysis Care
Dialysis is not simply a procedure performed by a machine. Comprehensive nephrology care remains important throughout treatment.
A nephrologist may monitor:
-
Kidney function
-
Blood pressure
-
Fluid balance
-
Electrolytes
-
Acid-base status
-
Hemoglobin and anemia
-
Bone and mineral health
-
Nutrition
-
Dialysis adequacy
-
Vascular access or peritoneal catheter concerns
-
Medication doses
-
Cardiovascular health
-
Transplant eligibility
Regular nephrology follow-up helps ensure that dialysis remains appropriate and is adjusted according to changing medical needs.
Dialysis and Chronic Kidney Disease
Chronic kidney disease usually develops gradually.
CKD can be categorized into different stages based largely on eGFR, together with evidence of kidney damage and other clinical findings.
Early-stage CKD may be managed with:
-
Blood pressure control
-
Diabetes management
-
Treatment to reduce albuminuria when appropriate
-
Lifestyle modifications
-
Dietary management
-
Medication review
-
Regular monitoring
Advanced CKD may eventually require kidney replacement therapy, but not every patient with CKD progresses to dialysis.
Early nephrology care can help slow progression and prepare patients appropriately if kidney replacement therapy becomes necessary.
Dialysis for Acute Kidney Injury
Dialysis is not limited to chronic kidney failure.
In severe Acute Kidney Injury, temporary dialysis may sometimes be required when complications cannot be controlled through other treatments.
Possible reasons include:
-
Severe potassium abnormalities
-
Significant fluid overload
-
Severe metabolic acidosis
-
Serious symptoms from waste accumulation
Some patients with AKI recover enough kidney function to stop dialysis, while others may develop persistent kidney impairment.
Preparing for Dialysis
Patients with progressive CKD may benefit from planning before dialysis becomes urgent.
Preparation may include:
-
Regular kidney-function monitoring
-
Education about dialysis options
-
Discussion of hemodialysis and peritoneal dialysis
-
Vascular access planning when hemodialysis is anticipated
-
Peritoneal catheter planning when appropriate
-
Dietary counseling
-
Medication review
-
Anemia management
-
Evaluation for kidney transplantation
Early preparation can help patients make informed decisions rather than having to start dialysis unexpectedly.
Kidney Transplant as an Alternative to Long-Term Dialysis
For suitable patients with advanced kidney failure, kidney transplantation may provide an alternative to long-term dialysis.
A transplant can restore kidney function through a functioning donor kidney.
However, transplantation requires:
-
Detailed medical evaluation
-
Donor assessment
-
Compatibility testing
-
Surgical treatment
-
Lifelong follow-up
-
Immunosuppressive medications
Not every patient is eligible for transplantation, so evaluation by a transplant team is necessary.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke provides kidney transplant evaluation and ongoing nephrology care for appropriate patients.
Diet and Lifestyle During Dialysis
Dietary requirements vary between patients and between dialysis modalities.
Depending on individual needs, a dialysis patient may need guidance regarding:
-
Sodium intake
-
Fluid intake
-
Potassium
-
Phosphorus
-
Protein
-
Calories
-
Vitamins and minerals
There is no single dialysis diet suitable for everyone.
Patients should follow a personalized nutrition plan prepared by their nephrologist or renal dietitian.
Other helpful habits include:
-
Taking medications as prescribed
-
Attending dialysis sessions consistently
-
Maintaining appropriate physical activity
-
Avoiding smoking
-
Monitoring blood pressure
-
Following vascular-access or catheter-care instructions
-
Keeping regular nephrology appointments
What Happens If a Dialysis Session Is Missed?
Missing dialysis can allow waste products and excess fluid to accumulate.
Depending on the patient's condition, this may result in:
-
Swelling
-
Breathlessness
-
High blood pressure
-
Electrolyte abnormalities
-
Increased potassium
-
Feeling unwell
-
Other potentially serious complications
Patients should contact their dialysis center or nephrology team promptly if they cannot attend a scheduled session.
Can Dialysis Cure Kidney Failure?
Dialysis does not cure chronic kidney failure.
It replaces some kidney functions while treatment continues.
For patients with irreversible end-stage kidney disease, long-term options may include:
-
Hemodialysis
-
Peritoneal dialysis
-
Kidney transplantation
-
Conservative kidney management in selected circumstances
The appropriate approach depends on the patient's health, preferences, treatment goals, and medical suitability.
When Should You Consult a Nephrologist?
You should consider nephrology evaluation if you have:
-
Persistently high creatinine
-
Reduced eGFR
-
Protein in the urine
-
Blood in the urine
-
Uncontrolled hypertension
-
Diabetes with kidney abnormalities
-
Recurrent kidney stones
-
Repeated urinary infections
-
Swelling
-
Reduced urine output
-
Abnormal electrolyte levels
-
Known chronic kidney disease
-
Possible kidney failure
Early specialist care may help delay progression and allow timely preparation for kidney replacement therapy when needed.

Frequently Asked Questions
What is the relationship between nephrology and dialysis?
Nephrology is the medical specialty concerned with kidney health and kidney disease. Dialysis is a kidney replacement therapy used when kidney function is severely impaired. Nephrologists assess when dialysis is needed and monitor patients receiving it.
Does everyone with kidney disease need dialysis?
No. Most people with early or moderate CKD do not need dialysis. Dialysis is generally considered when advanced kidney disease causes symptoms or complications that cannot be adequately managed otherwise.
Is dialysis based only on creatinine levels?
No. The decision depends on the overall clinical picture, including symptoms, fluid balance, electrolyte abnormalities, acid-base problems, nutrition, and kidney function.
Which is better: hemodialysis or peritoneal dialysis?
Neither is universally better. Both are established forms of dialysis, and the most suitable option depends on medical factors, lifestyle, home circumstances, and patient preference.
Can dialysis be temporary?
Yes. Dialysis may be temporary in some patients with severe acute kidney injury if kidney function subsequently recovers sufficiently.
Can a patient on dialysis receive a kidney transplant?
Some dialysis patients may be suitable candidates for kidney transplantation. Evaluation is required to determine eligibility and identify an appropriate transplant pathway.
What happens if I miss dialysis?
Missing dialysis can cause waste products, potassium, and fluid to accumulate. Patients should contact their dialysis team promptly if they miss or expect to miss a session.
Can dialysis patients drink as much water as they want?
Not necessarily. Fluid requirements depend on urine output, dialysis schedule, fluid retention, heart health, and other factors. Follow the individualized fluid recommendation provided by your healthcare team.
Conclusion
Nephrology and dialysis play complementary roles in the management of advanced kidney disease. Nephrology provides comprehensive medical care for kidney disorders, while dialysis can replace some of the kidneys' filtering functions when kidney failure becomes severe.
Hemodialysis and peritoneal dialysis are both established treatment options, and the choice should be made after considering medical needs, lifestyle, treatment goals, and patient preferences. Dialysis is not automatically required at a particular creatinine or eGFR level; the decision is based on the patient's overall clinical condition and complications.
