About Nephrology
Nephrology is the medical care of the kidneys. Nephrologists diagnose and treat chronic kidney disease, acute kidney injury, glomerular diseases (such as nephrotic syndrome and glomerulonephritis), kidney problems from diabetes and high blood pressure, electrolyte and fluid disorders, and difficult-to-control hypertension. They also manage kidney failure — including dialysis (haemodialysis and peritoneal dialysis) and care before and after a kidney transplant. Assessment usually involves blood and urine tests, imaging and sometimes a kidney biopsy. Much of nephrology is long-term care, focused on slowing kidney decline and protecting the heart and other organs.
Conditions and treatments commonly covered
Areas commonly seen in nephrology include:
- Chronic kidney disease
- Diabetic kidney disease
- Glomerulonephritis and nephrotic syndrome
- Difficult-to-control high blood pressure
- Dialysis (haemodialysis, peritoneal dialysis)
- Kidney transplant care
What to expect at a consultation
An initial consultation usually involves a discussion of your symptoms and medical history, a focused examination, and any tests needed to reach a diagnosis. The specialist will explain the findings, walk you through your options — including non-surgical approaches where relevant — and set out the likely costs and next steps before anything proceeds. If a procedure is recommended, it is reasonable to ask what it involves, the expected recovery time, the risks and the alternatives, so you can make an informed decision at your own pace. It helps to keep asking questions until you fully understand the plan.
Preparing for your appointment
- Bring referral letters, past reports, scan images and a list of your current medications.
- Note your main symptoms, when they started and what makes them better or worse.
- Write down the questions that matter most to you, and bring a family member if it helps.
After your consultation and follow-up
Depending on the diagnosis, you may be given medication, referred for further tests or imaging, scheduled for a procedure, or asked to return for review. Ask what warning signs should prompt earlier contact, how to get your results, and who to reach if you have questions between visits. Keeping your own copy of reports makes future care and any second opinion easier.
Costs, subsidies and financing in Singapore
For subsidised care at a public (restructured) hospital, a referral from a GP or polyclinic is generally needed; private specialists can usually be booked directly at full fees. Ask upfront for an estimate covering the consultation, tests and any procedure. Depending on the treatment, you may be able to use MediSave for approved day-surgery and procedures (within set limits), with MediShield Life or an Integrated Shield Plan helping for larger inpatient bills. Purely cosmetic procedures are not claimable. If cost is a concern, it is worth asking whether a subsidised referral is possible, and comparing written estimates between providers before you commit.
How to choose the right nephrologist in Singapore
Beyond credentials, it helps to match the specialist to your specific problem. Consider whether their sub-specialty fits your condition, how often they manage or operate on cases like yours, which hospital they admit to (and whether it suits your budget and insurance), and how clearly they explain your options and costs. Accreditation can be confirmed on the Register of Specialists and registration on the Singapore Medical Council register. Independent reviews are a useful signal for communication and experience, but weigh them alongside credentials rather than on their own.
Questions worth asking at your first consultation
- Are you an accredited specialist in the area my condition falls under?
- What are my options, including non-surgical or watch-and-wait approaches?
- How often do you treat or perform this, and what are the typical outcomes and risks?
- What is the full estimated cost, and what can I claim through MediSave or insurance?
- Are you comfortable with me seeking a second opinion?
Verifying credentials
In Singapore every practising doctor must be registered with the Singapore Medical Council, and specialists are additionally listed on the Register of Specialists maintained by the Specialist Accreditation Board — you can search both to confirm a doctor’s registration and field. The letters after a name (such as MRCP, FRCS or FAMS) reflect postgraduate training and fellowships, but the key question is simply whether the doctor is an accredited specialist in the area relevant to your care.
When to consider a second opinion
A second opinion is reasonable before major surgery, for a serious or unclear diagnosis, or when a recommended treatment feels aggressive or uncertain. Good specialists welcome it. Bring your reports and scans so the second doctor can assess the same information. You are entitled to a copy of your medical records to take along, and seeking another view will not offend a good specialist.
Common questions
When should I see a nephrologist?
For reduced kidney function on a blood test, protein or blood in the urine, difficult-to-control high blood pressure, or kidney disease related to diabetes.
Does chronic kidney disease always lead to dialysis?
No — many people never need dialysis. The aim is to slow progression through blood-pressure and diabetes control, medication and lifestyle.
What does a kidney biopsy involve?
A small needle sample of the kidney, taken under local anaesthetic with ultrasound guidance, to diagnose the cause of certain kidney conditions.
Do I need a referral to see this specialist?
For subsidised care at a public hospital you generally need a GP or polyclinic referral; private specialists can usually be seen directly.
How can I verify a doctor’s credentials?
Check the Singapore Medical Council’s Register of Medical Practitioners, and the Register of Specialists for accredited specialists.
