Nephrology is the medical specialty focused on the kidneys and the conditions that affect kidney function.
The kidneys do much more than produce urine. They remove waste from the bloodstream, regulate fluid and electrolyte levels, contribute to blood-pressure control and support processes involved in red blood cell production and bone health.
A nephrologist evaluates problems ranging from abnormal kidney-function tests and protein in urine to chronic kidney disease, acute kidney injury and advanced kidney failure.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized nephrology care for patients with a broad range of kidney disorders.
What Does a Nephrologist Treat?
Nephrologists manage medical conditions that affect the kidneys and their ability to function properly.
Common conditions include:
-
Chronic kidney disease
-
Acute kidney injury
-
Kidney failure
-
Diabetic kidney disease
-
Hypertension-related kidney disease
-
Proteinuria and albuminuria
-
Blood in urine
-
Glomerular diseases
-
Autoimmune kidney disorders
-
Polycystic kidney disease
-
Electrolyte disorders
-
Acid-base abnormalities
-
Recurrent kidney problems
-
Complications associated with advanced CKD
-
Dialysis-related medical problems
-
Kidney transplant-related medical care
Some urinary tract conditions, particularly those requiring surgery, may be managed by a urologist. Nephrologists and urologists may work together when a patient's condition involves both medical kidney disease and a structural or surgical problem.
Why Is Nephrology Important?
Kidney disease can develop gradually and may not produce noticeable symptoms in its early stages.
For example, a person can have:
-
Reduced eGFR
-
Albumin in urine
-
High blood pressure
-
Early diabetic kidney damage
without feeling unwell.
Nephrology helps identify the cause of kidney abnormalities, assess the degree of kidney involvement and establish a treatment strategy aimed at protecting kidney function.
When Should You Consult a Nephrologist?
A nephrology consultation may be appropriate when kidney tests or symptoms raise concern.
Elevated Creatinine
An increased creatinine level may result from acute kidney injury, chronic kidney disease, dehydration, medication effects or other conditions.
A nephrologist can evaluate the reason for the abnormal result rather than interpreting creatinine in isolation.
Reduced eGFR
Persistently reduced eGFR may indicate chronic kidney disease and should be assessed along with urine findings and other clinical information.
Protein in Urine
Persistent protein or albumin leakage can be an important indicator of kidney damage.
Difficult-to-Control Blood Pressure
Kidney disease and hypertension can influence each other. Persistent high blood pressure despite treatment may warrant specialist evaluation.
Recurrent Kidney Stones
People who repeatedly develop kidney stones may require assessment for metabolic or dietary factors contributing to stone formation.
Swelling
Unexplained swelling of the legs, feet, hands or around the eyes can sometimes be associated with kidney disease, although there are many other possible causes.
Acute Kidney Injury
A sudden decline in kidney function requires timely assessment to identify and treat the underlying cause.
Common Kidney Conditions in Nephrology
Chronic Kidney Disease
Chronic kidney disease involves persistent abnormalities in kidney structure or function.
Common contributors include:
-
Diabetes
-
High blood pressure
-
Glomerular diseases
-
Inherited kidney disorders
-
Autoimmune conditions
-
Previous kidney injury
Treatment aims to control the underlying cause, reduce complications and preserve remaining kidney function.
Acute Kidney Injury
Acute kidney injury develops over a relatively short period.
Possible causes include:
-
Severe dehydration
-
Serious infections
-
Blood loss
-
Low blood pressure
-
Certain medications
-
Urinary obstruction
-
Severe medical illness
Depending on the cause and severity, kidney function may recover partially or substantially.
Diabetic Kidney Disease
Diabetes can damage the kidney's filtering structures over time.
Nephrology care may involve monitoring:
-
Blood glucose
-
HbA1c
-
Blood pressure
-
Creatinine
-
eGFR
-
Urine albumin
Early detection of kidney involvement can help guide treatment and monitoring.
Hypertension-Related Kidney Disease
Long-standing high blood pressure can damage blood vessels in the kidneys.
At the same time, kidney disease can contribute to elevated blood pressure, creating a cycle that can accelerate kidney damage.
Appropriate blood-pressure management is therefore an important part of nephrology care.
Glomerular Diseases
The glomeruli are microscopic filtering units within the kidneys.
Diseases affecting these structures may cause:
-
Proteinuria
-
Blood in urine
-
Swelling
-
High blood pressure
-
Declining kidney function
Some glomerular disorders require specialized testing and treatment.
Kidney Failure
Advanced kidney failure occurs when the kidneys can no longer adequately perform their essential functions.
Depending on the individual situation, management may include:
-
Medical treatment of complications
-
Hemodialysis
-
Peritoneal dialysis
-
Kidney transplantation
-
Conservative kidney management
A nephrologist helps determine the appropriate treatment pathway.
How Does a Nephrologist Check Kidney Health?
Nephrology evaluation may involve several types of tests.
Blood Tests
Common tests include:
-
Serum creatinine
-
eGFR
-
Blood urea
-
Sodium
-
Potassium
-
Bicarbonate
-
Hemoglobin
-
Calcium
-
Phosphate
-
Glucose or HbA1c when appropriate
Urine Tests
Depending on the suspected condition, testing may assess:
-
Protein
-
Albumin
-
Blood
-
Infection
-
Other urinary abnormalities
The urine albumin-to-creatinine ratio can be useful for detecting albumin leakage.
Imaging
Kidney ultrasound or other imaging may be recommended to evaluate:
-
Kidney size
-
Stones
-
Cysts
-
Structural abnormalities
-
Urinary obstruction
Additional specialized tests may be required for certain kidney diseases.
Understanding Creatinine and eGFR
Two commonly discussed kidney-function measures are serum creatinine and eGFR.
Creatinine is a waste product removed primarily by the kidneys. When kidney filtration decreases, blood creatinine may increase.
eGFR provides an estimate of how effectively the kidneys are filtering.
However, neither result should be interpreted in isolation. Doctors consider the patient's age, body characteristics, previous results, urine findings, symptoms and medical history.
A rapidly changing creatinine value may be particularly important because it can indicate acute kidney injury.
What Are the Stages of Chronic Kidney Disease?
CKD is commonly categorized according to eGFR:
-
G1: eGFR 90 or above, when kidney damage is also present
-
G2: eGFR 60–89, when kidney damage is also present
-
G3a: eGFR 45–59
-
G3b: eGFR 30–44
-
G4: eGFR 15–29
-
G5: eGFR below 15
Urine albumin levels and other clinical findings are also important when assessing CKD.
A single abnormal eGFR does not necessarily establish chronic kidney disease. Persistence over time and clinical context matter.
How Is Kidney Disease Managed in Nephrology?
Treatment depends on the diagnosis.
Lifestyle and Dietary Management
Depending on kidney function and the underlying disease, patients may receive advice regarding:
-
Salt intake
-
Protein intake
-
Fluid intake
-
Potassium
-
Phosphorus
-
Weight management
-
Physical activity
There is no single diet suitable for every person with kidney disease.
Prescription Medicines
Depending on the diagnosis, medicines may be used to:
-
Control blood pressure
-
Manage diabetes
-
Reduce proteinuria
-
Correct anemia
-
Manage electrolyte abnormalities
-
Treat specific kidney diseases
-
Control complications of advanced CKD
Medicines should be selected and adjusted by a qualified healthcare professional.
Treatment of the Underlying Cause
Whenever possible, the condition responsible for kidney damage is addressed.
This may include managing:
-
Diabetes
-
Hypertension
-
Autoimmune disease
-
Glomerular disease
-
Infection
-
Urinary obstruction
Nephrology and Dialysis
When kidney function becomes severely impaired, some patients require kidney replacement therapy.
Hemodialysis
Hemodialysis uses a dialysis machine and filter to remove waste products and excess fluid from the blood.
Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdomen to help remove waste and excess fluid.
Dialysis does not necessarily mean that a person has permanently lost all kidney function. In some cases of acute kidney injury, dialysis may be temporary while the kidneys recover.
For established advanced kidney failure, long-term dialysis may be necessary unless transplantation or another appropriate management approach is available.
Nephrology and Kidney Transplantation
For selected patients with advanced kidney failure, kidney transplantation may be an option.
Transplant evaluation involves assessment of:
-
General health
-
Cardiovascular condition
-
Infection risks
-
Surgical suitability
-
Potential donor options
-
Other medical factors
Following transplantation, patients require ongoing nephrology care and anti-rejection medication.
Nephrology for People With Diabetes
People with diabetes have an increased risk of developing chronic kidney disease.
Regular assessment may include:
-
Blood pressure
-
Blood glucose
-
HbA1c
-
Serum creatinine
-
eGFR
-
Urine albumin
Kidney disease can be present before symptoms appear, making appropriate screening particularly important.
Nephrology for High Blood Pressure
High blood pressure is both a risk factor for kidney disease and a potential consequence of impaired kidney function.
Long-term management may include:
-
Regular blood-pressure monitoring
-
Appropriate medication
-
Sodium reduction when advised
-
Diabetes management
-
Healthy weight
-
Physical activity
-
Regular kidney-function assessment
Treatment goals should be individualized.
Can Nephrology Help Prevent Kidney Failure?
Not every case of kidney failure can be prevented.
However, appropriate management can help reduce the risk of progression for many forms of chronic kidney disease.
Important measures include:
-
Detecting kidney disease early
-
Controlling blood pressure
-
Managing diabetes
-
Treating proteinuria appropriately
-
Avoiding unnecessary medicines that can harm the kidneys
-
Maintaining a healthy lifestyle
-
Monitoring kidney function
-
Treating relevant underlying conditions
Patients with established CKD should follow an individualized monitoring and treatment plan.
When Is a Kidney Problem an Emergency?
Some symptoms require immediate medical assessment.
Seek urgent care for:
-
Severe breathlessness
-
Chest pain
-
Confusion or marked drowsiness
-
Very little or no urine
-
Severe swelling
-
Persistent vomiting
-
Severe weakness
-
High fever with flank pain
-
Rapid deterioration in general health
The combination of urinary obstruction and infection can be particularly serious.

Frequently Asked Questions About Nephrology
What does nephrology mean?
Nephrology is the medical specialty concerned with kidney diseases, kidney function, related electrolyte and acid-base disorders, dialysis and medical management surrounding kidney transplantation.
Is a nephrologist the same as a kidney specialist?
Yes. A nephrologist is a physician who specializes in medical kidney conditions and is commonly referred to as a kidney specialist.
When should I see a nephrologist?
You may need a nephrology consultation if you have persistent protein in urine, abnormal creatinine, reduced eGFR, unexplained swelling, difficult-to-control blood pressure, acute kidney injury or known chronic kidney disease.
Can nephrology treat kidney stones?
Nephrologists can evaluate the medical and metabolic factors associated with recurrent kidney stones. A urologist may be required when a stone needs a surgical or endoscopic procedure.
Does kidney disease always cause symptoms?
No. Many kidney disorders, particularly early CKD, can be present without noticeable symptoms.
Can kidney function improve?
It depends on the cause. Some cases of acute kidney injury can improve substantially after treatment. Established chronic kidney damage is generally managed rather than completely reversed.
Conclusion
Nephrology plays an important role in identifying, treating and monitoring medical conditions that affect kidney function. From early abnormalities such as proteinuria and reduced eGFR to complex conditions requiring dialysis or kidney transplantation, specialist assessment can help guide appropriate care.
Kidney disease may remain silent for years, so people with diabetes, hypertension, recurrent kidney problems or abnormal kidney-function tests should discuss appropriate evaluation with a healthcare professional.
