Overview

The Institute of Nephrology provides comprehensive care for diseases affecting the kidneys and urinary system. It focuses on prevention, early diagnosis, treatment, dialysis, kidney transplant care, and long-term management of kidney-related conditions.

Kidney disease can be silent in the early stages and may only be detected through blood tests, urine tests, or blood pressure checks. Timely nephrology care helps slow disease progression, prevent complications, and improve quality of life.

What Is Nephrology?

Nephrology is the medical specialty that deals with kidney health. A nephrologist diagnoses and treats conditions that affect kidney function, fluid balance, blood pressure, electrolytes, and waste removal from the body.

Common areas of care include:

• Chronic kidney disease

• Acute kidney injury

• Kidney failure

• Diabetic kidney disease

• Hypertension-related kidney disease

• Glomerulonephritis

• Nephrotic syndrome

• Polycystic kidney disease

• Kidney stones and recurrent kidney infections

• Electrolyte and acid-base disorders

• Haemodialysis and peritoneal dialysis

• Kidney transplant evaluation and follow-up

• Interventional nephrology and dialysis access care

• Paediatric nephrology in children with kidney disorders

The goal is to protect kidney function and provide the right treatment at every stage of disease.

Causes and Risk Factors

Kidney disease may develop gradually over time or suddenly due to illness, infection, medicines, dehydration, or obstruction.

Common causes and risk factors include:

• Diabetes

• High blood pressure

• Family history of kidney disease

• Recurrent urinary tract infections

• Kidney stones or urinary blockage

• Autoimmune diseases such as lupus

• Polycystic kidney disease

• Long-term use of certain painkillers or kidney-harming medicines

• Heart disease or liver disease

• Older age

• Obesity and smoking

• Severe infection, dehydration, or shock

People with diabetes, hypertension, or a family history of kidney disease should undergo regular kidney screening.

Symptoms

Kidney disease may not cause symptoms in the beginning. As kidney function declines, symptoms may become more noticeable.

Common symptoms include:

• Swelling in the feet, ankles, legs, or face

• Reduced or increased urination

• Foamy urine or blood in urine

• Fatigue and weakness

• Nausea, vomiting, or loss of appetite

• High blood pressure

• Shortness of breath

• Muscle cramps

• Persistent itching

• Poor sleep or restlessness

• Back, side, or abdominal pain

• Confusion or drowsiness in severe cases

Emergency care is needed for very little urine, severe breathlessness, chest pain, confusion, seizures, sudden swelling, or symptoms of severe infection.

Diagnosis

Diagnosis begins with medical history, physical examination, blood pressure measurement, and tests to assess kidney function and identify the cause.

Common diagnostic methods include:

• Blood tests for creatinine, urea, electrolytes, and eGFR

• Urine routine examination

• Urine albumin-to-creatinine ratio

• Blood sugar and HbA1c testing

• Kidney ultrasound

• CT scan or other imaging for stones, obstruction, or structural problems

• Autoimmune and infection-related blood tests when needed

• Kidney biopsy in selected cases

• Dialysis access evaluation for patients needing haemodialysis

• Transplant evaluation for eligible patients with kidney failure

Regular monitoring helps detect progression early and guides treatment decisions.

Treatment Options

Treatment depends on the cause, stage of kidney disease, symptoms, and overall health.

Nephrology care may include:

• Medicines to control blood pressure, diabetes, swelling, anaemia, bone-mineral problems, and electrolyte imbalance

• Diet and fluid guidance based on kidney function

• Avoidance or adjustment of medicines that may affect the kidneys

• Treatment of infections, stones, autoimmune disease, or urinary blockage

• Haemodialysis for advanced kidney failure

• Peritoneal dialysis for suitable patients

• Kidney transplant evaluation and post-transplant care

• Interventional nephrology procedures for dialysis access

• Critical care nephrology for ICU patients with acute kidney injury

• Long-term follow-up to monitor kidney function and complications

Treatment is personalised to preserve kidney function, manage symptoms, and support daily life.

Prevention and Outlook

Many kidney problems can be prevented or delayed by controlling diabetes and blood pressure, maintaining a healthy weight, reducing salt intake, staying hydrated, avoiding tobacco, limiting unnecessary painkiller use, treating urinary infections early, and attending regular check-ups.

The outlook depends on the cause, stage, and response to treatment. Early kidney disease can often be slowed with proper care. Advanced kidney failure may require dialysis or kidney transplant, but with modern nephrology care, many patients can continue active and meaningful lives.

Frequently Asked Questions

1. When should I see a nephrologist?
   You should consult a nephrologist for reduced kidney function, protein or blood in urine, difficult-to-control blood pressure, swelling, recurrent kidney stones, recurrent urinary infections, or abnormal kidney test results.

2. Can kidney disease be silent?
   Yes. Early kidney disease often has no symptoms and may only be detected through blood and urine tests.

3. What are the main causes of kidney failure?
   Diabetes and high blood pressure are among the most common causes. Other causes include kidney inflammation, inherited kidney disease, infections, stones, obstruction, and certain medicines.

4. Is dialysis permanent?
   Dialysis may be temporary in some cases of acute kidney injury. In advanced chronic kidney failure, dialysis is usually long-term unless a kidney transplant is possible.

5. Is kidney transplant a cure?
   A kidney transplant is a treatment for kidney failure, not a complete cure. Patients need lifelong follow-up and anti-rejection medicines.

6. How can I protect my kidneys?
   Control blood pressure and diabetes, avoid smoking, reduce salt intake, stay active, maintain a healthy weight, drink fluids as advised, and avoid unnecessary painkillers.
