Nephrology physicians are doctors who specialize in the medical diagnosis, treatment and long-term management of diseases affecting the kidneys.

A nephrologist evaluates how well the kidneys are functioning, investigates abnormalities in blood and urine tests, identifies the causes of kidney disease and manages complications that can develop when kidney function declines.

Nephrology is not limited to advanced kidney failure. A nephrology physician may also evaluate patients with:

• Abnormal creatinine

• Reduced eGFR

• Protein in urine

• Blood in urine

• High blood pressure related to kidney disease

• Electrolyte abnormalities

• Acute kidney injury

• Chronic kidney disease

• Glomerular diseases

• Recurrent kidney-related problems

• Dialysis requirements

• Kidney transplant-related medical care

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for a broad range of kidney conditions.

What Does a Nephrology Physician Do?

A nephrology physician looks beyond an isolated laboratory result.

For example, an elevated creatinine level may occur because of acute kidney injury, dehydration, urinary obstruction, medication effects or chronic kidney disease. The nephrologist investigates the reason rather than treating the number alone.

A nephrology consultation may involve:

• Reviewing symptoms

• Examining previous kidney-function results

• Assessing blood pressure

• Reviewing medications

• Checking urine findings

• Estimating kidney function

• Looking for the underlying cause

• Assessing complications

• Planning follow-up and treatment

This approach helps determine whether the kidney abnormality is temporary, progressive or related to another medical condition.

Which Kidney Conditions Do Nephrology Physicians Treat?

Nephrologists manage many medical kidney conditions.

Chronic Kidney Disease

CKD involves persistent kidney damage or reduced kidney function over time.

Treatment focuses on identifying the cause, slowing progression, controlling complications and preserving remaining kidney function.

Acute Kidney Injury

Acute kidney injury is a sudden deterioration in kidney function.

Possible causes include:

• Dehydration

• Infection

• Low blood pressure

• Certain medicines

• Severe illness

• Urinary obstruction

• Kidney inflammation

Some forms of AKI can improve considerably when the underlying cause is addressed promptly.

Proteinuria

Protein in urine can be an important marker of kidney damage.

A nephrologist may investigate whether proteinuria is related to diabetes, hypertension, glomerular disease, infection, autoimmune conditions or another cause.

Hematuria

Blood in urine can originate from different parts of the urinary system.

When kidney disease is suspected, a nephrologist can assess whether the blood may be associated with glomerular or other renal disease.

Glomerular Diseases

Diseases affecting the kidney's filtering units can cause:

• Proteinuria

• Hematuria

• Swelling

• High blood pressure

• Declining kidney function

Some patients require specialized investigations and, in selected cases, a kidney biopsy.

Electrolyte Disorders

The kidneys play an important role in regulating electrolytes and acid-base balance.

Nephrologists may manage abnormalities involving:

• Potassium

• Sodium

• Bicarbonate

• Calcium

• Phosphorus

• Magnesium

The significance of an abnormal value depends on the overall clinical situation.

When Should You See a Nephrology Physician?

A kidney specialist may be appropriate when tests or symptoms suggest possible kidney disease.

Consider nephrology evaluation for:

• Persistently high creatinine

• Reduced eGFR

• Protein or albumin in urine

• Repeated blood in urine

• Unexplained swelling

• Difficult-to-control blood pressure

• Recurrent acute kidney injury

• Persistent electrolyte abnormalities

• Progressive kidney-function decline

• Suspected glomerular disease

• Advanced chronic kidney disease

• Kidney failure

Early evaluation can sometimes identify potentially treatable causes before substantial kidney damage develops.

Can a Nephrologist Help With High Creatinine?

Yes, but treatment depends on why creatinine is elevated.

There is no universal medicine that simply lowers creatinine for every patient.

A nephrologist may determine whether the elevation is associated with:

• Dehydration

• Acute kidney injury

• Chronic kidney disease

• Urinary obstruction

• Medication effects

• Infection

• High muscle mass or other factors

• Another underlying condition

If a reversible cause is identified and treated, creatinine may improve.

What Tests Are Used in Nephrology?

A nephrology evaluation may involve several types of testing.

Blood Tests

Common investigations include:

• Serum creatinine

• eGFR

• Urea

• Sodium

• Potassium

• Bicarbonate

• Hemoglobin

• Calcium

• Phosphorus

Additional tests may be selected according to the suspected condition.

Urine Tests

Urine evaluation can include:

• Urinalysis

• Urine albumin-to-creatinine ratio

• Protein measurement

• Microscopic examination

• Urine culture when infection is suspected

Imaging

Depending on the clinical question, imaging may include:

• Kidney ultrasound

• CT

• Other appropriate imaging

Imaging can help evaluate kidney structure, urinary obstruction, stones and other abnormalities.

Kidney Biopsy

A kidney biopsy may be considered in selected patients when identifying the precise kidney disease would change treatment.

It is not required for every kidney problem.

Nephrology Physicians and High Blood Pressure

Kidney disease and hypertension can influence each other.

Long-standing high blood pressure can damage kidney blood vessels, while kidney disease can make blood pressure more difficult to control.

A nephrologist may assess:

• Blood-pressure readings

• Kidney function

• Albuminuria

• Electrolytes

• Current medications

• Cardiovascular risk

Treatment is individualized according to the patient's kidney condition and overall health.

Nephrology Care for Diabetes and Kidney Disease

Diabetes is a major risk factor for chronic kidney disease.

Kidney evaluation may include monitoring:

• eGFR

• Urine albumin

• Blood glucose

• HbA1c

• Blood pressure

• Cardiovascular risk

Depending on the patient's condition, kidney-protective therapies may be considered alongside appropriate diabetes treatment.

Early identification of albuminuria can be particularly useful in patients at risk of diabetic kidney disease.

Nephrology Physicians and Kidney Stones

Many kidney stones are primarily managed by urologists, particularly when a procedure is required.

However, a nephrologist can be valuable when stones are associated with:

• Recurrent stone formation

• Abnormal kidney function

• Metabolic abnormalities

• Repeated urinary complications

• A need for stone-prevention evaluation

Stone analysis and metabolic assessment can help selected patients understand why stones are forming repeatedly.

When surgical stone removal is required, nephrologists and urologists may coordinate care according to the patient's needs.

Nephrology Care for Dialysis Patients

When kidney function becomes severely impaired, kidney replacement therapy may become necessary for some patients.

A nephrologist can manage:

• Hemodialysis

• Peritoneal dialysis

• Dialysis-related complications

• Fluid balance

• Electrolyte abnormalities

• Anemia

• Mineral and bone disorders

• Blood-pressure management

• Dialysis access-related medical concerns

Dialysis is not started simply because creatinine crosses one particular number. The decision depends on kidney function, symptoms, complications and the overall clinical situation.

What Is the Role of a Nephrology Physician in Kidney Transplantation?

Nephrologists with transplant expertise may be involved before and after kidney transplantation.

Before transplantation, assessment may include:

• Kidney-failure management

• Transplant suitability

• Medical evaluation

• Cardiovascular assessment

• Infection screening

• Discussion of kidney replacement options

After transplantation, ongoing monitoring may involve:

• Kidney function

• Immunosuppressive medicines

• Blood pressure

• Infection risk

• Proteinuria

• Possible rejection

• Medication-related kidney problems

A rise in creatinine after transplantation does not automatically mean rejection. Several possible causes need to be investigated.

Nephrology Physicians and Electrolyte Problems

The kidneys regulate important electrolytes and acid-base balance.

A nephrologist may evaluate abnormal:

• Potassium

• Sodium

• Bicarbonate

• Calcium

• Phosphorus

• Magnesium

Some electrolyte abnormalities can become medically urgent, particularly when severe or associated with heart, neurological or other systemic symptoms.

Treatment should therefore be based on the specific abnormality and its underlying cause.

Can Nephrology Physicians Treat Kidney Failure?

Nephrologists manage patients with advanced kidney disease and kidney failure.

Treatment planning may include:

• Medical management

• Hemodialysis

• Peritoneal dialysis

• Kidney transplantation

• Conservative kidney management in selected patients

The appropriate approach depends on kidney function, symptoms, complications, overall health and patient preferences.

Nephrologist and Urologist: What Is the Difference?

The two specialties often work together but focus on different areas.

Nephrologist

A nephrologist primarily manages medical kidney diseases, such as:

• CKD

• AKI

• Proteinuria

• Glomerular diseases

• Hypertension related to kidney disease

• Electrolyte disorders

• Dialysis

• Transplant medicine

Urologist

A urologist manages many structural and surgical conditions involving the urinary system and male reproductive system.

This may include:

• Kidney stones requiring procedures

• Ureteral obstruction

• Certain urinary tract abnormalities

• Prostate conditions

• Urinary tract surgery

Some patients benefit from both specialists.

What Should You Bring to a Nephrology Appointment?

Preparing previous medical information can make a consultation more useful.

If available, bring:

• Previous creatinine reports

• eGFR results

• Urine reports

• Ultrasound or CT reports

• Blood-pressure records

• Diabetes test results

• Current medication list

• Previous hospital records

• Dialysis records if applicable

• Previous kidney biopsy reports

A trend in kidney-function results can often provide more information than a single test.

How Can You Protect Kidney Function?

Kidney protection depends on the underlying condition.

General measures may include:

• Control blood pressure appropriately.

• Manage diabetes when present.

• Take prescribed medicines correctly.

• Avoid unnecessary NSAID use.

• Avoid unverified kidney supplements and detox products.

• Follow an individualized diet.

• Maintain appropriate fluid intake.

• Attend recommended kidney-function monitoring.

• Address urinary obstruction promptly.

• Seek evaluation for persistent protein or blood in urine.

Patients with advanced kidney disease should follow individualized dietary and fluid recommendations rather than adopting generic kidney diets.

When Is a Kidney Problem an Emergency?

Certain symptoms require urgent medical attention.

Seek immediate medical care for:

• Very little or no urine

• Severe breathlessness

• Chest pain

• Confusion

• Severe or rapidly increasing swelling

• Persistent vomiting with dehydration

• Severe weakness

• Severe flank pain with fever or chills

• Rapid deterioration in health

These symptoms can occur with serious kidney, urinary or systemic problems.

Frequently Asked Questions

What does a nephrology physician treat?

A nephrology physician treats medical conditions affecting the kidneys, including chronic kidney disease, acute kidney injury, proteinuria, glomerular diseases, electrolyte disorders, kidney-related hypertension, dialysis-related conditions and transplant medicine.

When should I consult a nephrologist?

You may need nephrology evaluation if you have persistent high creatinine, reduced eGFR, significant protein in urine, unexplained blood in urine, difficult-to-control hypertension, recurrent kidney problems or progressive loss of kidney function.

Is a nephrologist the same as a kidney doctor?

Yes. A nephrologist is a physician specializing in the medical diagnosis and treatment of kidney diseases.

Do nephrologists perform kidney stone surgery?

Kidney stone procedures are generally performed by urologists. A nephrologist may evaluate kidney function, recurrent stones and metabolic risk factors and coordinate care with a urologist when necessary.

Can a nephrologist treat kidney failure?

Yes. Nephrologists manage advanced kidney disease and kidney failure, including medical treatment, dialysis planning, dialysis care and kidney transplant-related medical management.

Can a nephrologist lower creatinine?

A nephrologist treats the condition causing elevated creatinine rather than simply targeting the number. If the cause is reversible, kidney function and creatinine may improve.

What tests should I get before seeing a nephrologist?

Depending on your situation, useful reports may include creatinine, eGFR, urine testing, blood pressure readings, electrolytes and kidney imaging. Your doctor can determine which tests are necessary.

Conclusion

Nephrology physicians specialize in the medical care of the kidneys and play an important role across the entire spectrum of kidney disease, from early abnormalities in urine or kidney-function tests to advanced kidney failure and transplantation.

A nephrologist does more than treat high creatinine. The specialist looks for the underlying cause, assesses kidney-function trends, manages complications and develops a treatment strategy suited to the patient's condition.

Early specialist evaluation can be valuable when kidney abnormalities persist, particularly in people with diabetes, hypertension, proteinuria, recurrent kidney problems or declining eGFR.
