Nephrology

Kidneys remove waste and excess fluid from the blood, regulate electrolytes, support blood-pressure control and help maintain several essential body functions. Kidney disease can develop gradually and may not produce noticeable symptoms until kidney function has already declined.

The Department of Nephrology at ANU Hospitals provides evaluation and treatment for acute and chronic kidney conditions, difficult-to-control hypertension, electrolyte disorders and kidney failure. Services listed by the hospital include renal biopsy, vascular access, haemodialysis, peritoneal dialysis and kidney-transplantation care.

Patients searching for a nephrologist in Vijayawada, kidney specialist in Vijayawada or reliable kidney hospitals in Vijayawada can consult the Nephrology team for diagnosis, personalised treatment, dialysis planning and long-term follow-up.

What Is Nephrology?

Nephrology is the medical speciality concerned with kidney function, kidney diseases, fluid and electrolyte balance and certain forms of high blood pressure. A doctor specialising in this area is called a nephrologist.

A nephrologist evaluates changes in creatinine, protein or blood in the urine, unexplained swelling, reduced urine production, electrolyte abnormalities and other signs of impaired kidney function. The specialist also manages dialysis and helps patients understand treatment options when kidney function becomes severely reduced.

Early nephrology consultation may help identify the cause of kidney damage, treat reversible problems and slow the progression of chronic kidney disease.

Nephrologist vs Urologist

A nephrologist primarily manages kidney diseases through medical treatment, monitoring and dialysis. This includes chronic kidney disease, nephritis, nephrotic syndrome, electrolyte problems, hypertension and kidney failure.

A urologist is a surgical specialist who treats structural and surgical conditions involving the kidneys, ureters, bladder, prostate and urinary tract. Kidney stones, urinary obstruction and prostate problems may require urological evaluation.

Some patients need coordinated care from both specialists. ANU Hospitals can direct patients to the appropriate department based on their symptoms and investigation results.

Conditions Treated

The department manages acute kidney injury, chronic kidney disease, kidney failure, nephrotic syndrome, glomerulonephritis and diabetic kidney disease.
It also evaluates protein or blood in the urine, electrolyte abnormalities, fluid retention and hypertension associated with kidney dysfunction.
Patients requiring dialysis, renal biopsy, vascular-access care or kidney-transplant evaluation receive treatment according to their clinical condition.

Acute Kidney Injury

Acute kidney injury is a sudden decline in kidney function that can develop over hours or days. Possible causes include severe dehydration, infection, low blood pressure, urinary obstruction, certain medicines or serious illness.

Symptoms may include:

• Reduced urine output
• Swelling
• Nausea or vomiting
• Drowsiness or confusion
• Breathlessness
• Sudden weakness
• Abnormal blood-test results

Acute kidney injury can be serious but may be reversible when the cause is identified and treated promptly.

Chronic Kidney Disease

Chronic kidney disease, or CKD, is a gradual loss of kidney function over time. Diabetes and high blood pressure are common causes, but kidney inflammation, inherited disorders, repeated infections and long-term obstruction may also contribute.

Early CKD may not cause symptoms. It is often detected through blood tests showing reduced kidney filtration or urine tests showing excess protein.

Treatment focuses on slowing further damage, managing the underlying cause and reducing complications. Advanced kidney disease may require dialysis or transplant evaluation.

Diabetic Kidney Disease

Persistently high blood glucose can damage the kidneys’ filtering units. Early diabetic kidney disease may appear as increased albumin or protein in the urine before a major rise in creatinine occurs.

Management may include:

• Individualised glucose control
• Blood-pressure management
• Kidney-protective medicines when appropriate
• Urine-protein monitoring
• Kidney-function testing
• Diet and lifestyle guidance
• Cardiovascular-risk management

Patients with diabetes should have kidney screening according to their doctor’s advice, even when they have no symptoms.

Hypertensive Kidney Disease

High blood pressure can damage kidney blood vessels, while kidney disease can also make hypertension more difficult to control. This creates a cycle that may progressively affect both kidney and cardiovascular health.

A nephrologist may evaluate patients whose blood pressure remains high despite treatment, especially when kidney tests are abnormal or protein is detected in the urine.

Nephrotic Syndrome

Nephrotic syndrome occurs when the kidneys allow a large amount of protein to leak into the urine. It can cause swelling around the eyes, legs or abdomen, weight gain from fluid retention and foamy urine.

The underlying cause must be identified. Treatment varies and may include medicines, dietary changes and monitoring for complications.

Glomerulonephritis

Glomerulonephritis refers to inflammation affecting the kidneys’ filtering units. It may cause blood or protein in the urine, swelling, high blood pressure or reduced kidney function.

Some forms progress rapidly and require urgent treatment. Blood tests, urine tests and sometimes a kidney biopsy may be necessary to determine the cause.

Polycystic Kidney Disease

Polycystic kidney disease is an inherited condition in which multiple fluid-filled cysts develop in the kidneys. It may be associated with hypertension, pain, blood in the urine, infections or gradual decline in kidney function.

Family history, ultrasound and other investigations may help establish the diagnosis. Treatment focuses on monitoring kidney function, controlling blood pressure and managing complications.

Electrolyte Disorders

The kidneys help regulate sodium, potassium and the body’s acid–base balance. Kidney dysfunction, medicines, dehydration and other illnesses can cause abnormal electrolyte levels.

Severely high potassium can affect heart rhythm and may become life-threatening. Electrolyte abnormalities should be treated according to laboratory results and the underlying cause.

Symptoms

Possible kidney-disease symptoms include swelling of the feet or face, reduced urine, foamy urine, blood in the urine, fatigue and persistent nausea.
Breathlessness, uncontrolled blood pressure, muscle cramps, itching, loss of appetite and unexplained changes in urination may also require kidney evaluation.
Kidney disease can remain silent during its early stages, so people with diabetes, hypertension or a family history may need screening even without symptoms.

Other concerns include:

• Increased or reduced urination
• Frequent nighttime urination
• Pain or burning during urination
• Persistent puffiness around the eyes
• Swelling of the ankles or legs
• Sudden weight gain from fluid retention
• Dark, red or tea-coloured urine
• Persistent foamy urine
• Flank or lower-back discomfort
• Recurrent urinary infections
• Severe tiredness
• Difficulty concentrating
• Metallic taste or bad breath
• Dry or itchy skin
• Reduced appetite
• Persistent nausea or vomiting

These symptoms are not specific to kidney disease. A clinical evaluation and appropriate tests are required to determine their cause.

When to Seek Emergency Kidney Care

Seek immediate medical attention for:

• Sudden or severe reduction in urine
• Complete inability to pass urine
• Severe breathlessness
• Chest pain or palpitations
• Rapidly increasing swelling
• Severe weakness with confusion
• Persistent vomiting and dehydration
• Seizures or loss of consciousness
• Very high blood pressure with severe headache or vision changes
• Fever with reduced urine or severe urinary symptoms
• Blood in the urine with clots or difficulty urinating
• A dialysis catheter that is bleeding, displaced or appears infected
• Redness, pain or discharge around dialysis access
• Missed dialysis with breathlessness, swelling or confusion

Kidney emergencies require hospital assessment. Do not attempt to correct serious electrolyte abnormalities or fluid overload through home remedies.

Diagnosis

Kidney assessment begins with a review of symptoms, medical history, medicines, diabetes, blood pressure and previous laboratory reports.
Blood and urine tests are used to measure kidney function, detect protein or blood and assess electrolyte and acid–base balance.
Ultrasound, Doppler imaging, CT, MRI or kidney biopsy may be recommended when additional information is needed to identify the cause.

Kidney Function Tests

Common investigations include:

• Serum creatinine
• Estimated glomerular filtration rate
• Blood urea
• Sodium and potassium
• Bicarbonate and other electrolytes
• Calcium and phosphorus
• Complete blood count
• Blood glucose and HbA1c
• Urine routine examination
• Urine albumin-to-creatinine ratio
• Twenty-four-hour urine testing in selected cases

A single creatinine result does not always establish chronic kidney disease. Results must be interpreted with previous readings, urine findings, symptoms and medical history.

Imaging

Kidney ultrasound may be used to assess:

• Kidney size and structure
• Cysts or masses
• Urinary obstruction
• Hydronephrosis
• Bladder retention
• Selected blood-flow abnormalities

CT, MRI or vascular imaging may be recommended when clinically indicated.

Renal Biopsy

A renal or kidney biopsy involves collecting a small tissue sample for microscopic examination. It may help diagnose certain inflammatory, autoimmune or unexplained kidney conditions.

Biopsy is not required for every patient. The nephrologist discusses why it is being recommended, how to prepare and possible risks such as bleeding.

Treatment

Treatment may include blood-pressure control, diabetes management, kidney-protective medicines, fluid management and correction of electrolyte abnormalities.
Dietary recommendations are personalised according to kidney function, potassium, sodium, phosphorus, protein requirements and other medical conditions.
Advanced kidney failure may require haemodialysis, peritoneal dialysis or kidney-transplant evaluation after detailed specialist counselling.

Medical Management

Treatment depends on the cause and stage of kidney disease and may involve:

• Blood-pressure medicines
• Diabetes management
• Medicines to reduce urine protein
• Diuretics for selected patients with fluid overload
• Treatment of anaemia
• Correction of calcium and phosphorus imbalance
• Management of high potassium
• Treatment of infection
• Immunosuppressive treatment for selected inflammatory diseases
• Review of medicines that may affect the kidneys

Patients should not stop prescribed medicines without consulting their doctor. Some medicines require dose adjustment when kidney function declines.

Kidney-Friendly Nutrition

There is no single kidney diet suitable for every patient. Dietary advice varies according to kidney function, dialysis status, laboratory results and nutritional needs.

A personalised plan may address:

• Sodium intake
• Fluid intake
• Protein quantity and source
• Potassium
• Phosphorus
• Blood-glucose control
• Heart-healthy food choices
• Adequate calorie intake

Patients should not severely restrict water, fruits, vegetables or protein without professional advice. Unnecessary restriction can lead to dehydration or malnutrition.

Dialysis Services

Dialysis removes waste and excess fluid when the kidneys can no longer perform these functions adequately. The decision to begin dialysis is based on the patient’s symptoms, laboratory findings, fluid status and overall condition—not on a single creatinine result.

Haemodialysis

Haemodialysis filters the blood through a dialysis machine. Blood is taken through vascular access, cleaned and returned to the body.

Treatment frequency and duration are determined by the nephrologist. Patients require monitoring of blood pressure, access function, fluid balance and laboratory results.

Peritoneal Dialysis

Peritoneal dialysis uses the lining of the abdomen as a natural filter. Special dialysis fluid enters and leaves the abdominal cavity through a catheter.

It may provide greater flexibility for selected patients but requires proper training, hygiene and monitoring to reduce infection risk.

Vascular Access

Haemodialysis access may involve an arteriovenous fistula, graft or venous catheter. A fistula is generally planned in advance because it requires time to mature.

Patients should seek prompt evaluation if dialysis access becomes painful, swollen, red, starts bleeding or loses its usual vibration.

Kidney Transplantation

Kidney transplantation may be considered for suitable patients with kidney failure. Evaluation involves reviewing the patient’s overall health, infection risk, heart condition and other medical factors.

Care may include:

• Pre-transplant kidney assessment
• Donor and recipient evaluation
• Coordination with transplant specialists
• Management before transplantation
• Monitoring of anti-rejection medicines
• Post-transplant kidney-function follow-up

Patients should confirm the current transplant programme, surgical arrangements and eligibility process directly with ANU Hospitals.

Technology

Nephrology uses laboratory monitoring, kidney ultrasound, Doppler imaging and digital records to assess kidney function and track disease progression.
Dialysis machines, water-treatment systems and vascular-access monitoring support renal-replacement therapy for patients with kidney failure.
Technology provides important clinical information, but treatment decisions must be made by a qualified nephrologist after evaluating the complete medical picture.

Kidney-care technology may include:

• Automated laboratory testing
• Estimated kidney-filtration calculations
• Urine-protein measurement
• Ultrasound and Doppler imaging
• Haemodialysis equipment
• Peritoneal-dialysis systems
• Blood-pressure monitoring
• Dialysis-access surveillance
• Electronic tracking of laboratory trends

Every technology or facility listed on the final website should be confirmed as currently available at ANU Hospitals.

Preventing Further Kidney Damage

People with kidney disease may help protect their remaining kidney function by:

• Controlling blood pressure
• Managing diabetes
• Avoiding tobacco
• Maintaining an appropriate weight
• Following personalised dietary advice
• Taking medicines as prescribed
• Attending regular blood and urine tests
• Avoiding dehydration
• Seeking early treatment for infections
• Avoiding unnecessary painkillers and supplements
• Informing doctors about reduced kidney function before tests or procedures

Some over-the-counter painkillers, herbal remedies and bodybuilding supplements may affect kidney function. Patients should discuss these products with their nephrologist.

Frequently Asked Questions

When should I consult a nephrologist?

Consult a nephrologist if you have high creatinine, reduced kidney filtration, protein or blood in the urine, swelling, difficult-to-control blood pressure or recurrent electrolyte abnormalities.

Does high creatinine always mean kidney failure?

No. Creatinine may increase for several reasons, including dehydration, acute illness, medicines or kidney injury. The result should be interpreted with previous tests, urine findings and clinical assessment.

Can chronic kidney disease be cured?

Some causes of kidney dysfunction may be treatable or reversible. Established chronic kidney disease is generally managed by treating its cause, slowing progression and preventing complications. Avoid claims of guaranteed kidney restoration.

Does every patient with kidney disease need dialysis?

No. Many patients can be managed with medicines, monitoring and lifestyle changes. Dialysis is considered when kidney function is severely reduced and the patient has specific clinical indications.

Can dialysis be stopped after kidney function improves?

Dialysis used for acute kidney injury may sometimes be stopped if kidney function recovers sufficiently. Dialysis for permanent kidney failure is usually continued unless the patient receives a functioning kidney transplant.

What should I bring to a nephrology appointment?

Bring blood and urine reports, scan results, prescriptions, blood-pressure records, hospital discharge summaries, dialysis documents and a complete list of medicines and supplements.
