Understanding kidney failure
The kidneys filter waste and excess fluid from the blood, balance minerals and salts, and help regulate blood pressure. When their filtering capacity falls below roughly 15% of normal — a state called end-stage kidney disease (ESKD) — the body can no longer stay balanced on its own, and some form of renal replacement therapy becomes necessary.
Kidney failure is not one sudden event for most people. Chronic kidney disease (CKD) progresses through stages, measured by a blood test called eGFR(estimated glomerular filtration rate). Diabetes and high blood pressure are the two leading causes of kidney failure in India; they damage the kidney's filtering units slowly, over years, often with few symptoms until the damage is advanced.
This is why the first diagnosis of significant kidney disease often comes as a shock at an advanced stage. Understanding the condition — and the options available — is the first step your family can take together.
The symptoms at advanced stages include tiredness, swelling of the feet and face, poor appetite, nausea, a persistent metallic taste, muscle cramps and difficulty concentrating. None of these is specific on its own, which is why the diagnosis usually rests on blood and urine tests rather than symptoms — especially the creatinine value in your blood and the presence of protein or blood in the urine. If your reports show a rising creatinine, weeks of confusion can be avoided by one honest conversation with a nephrologist about what comes next.
When a transplant is considered
Two treatments replace failed kidney function: dialysis and kidney transplantation. Both are reliable; a transplant differs because it restores near-normal kidney function rather than substituting for it.
For most eligible patients, transplantation offers the best long-term outcome: better survival, fewer dietary restrictions, more energy, and freedom from the dialysis schedule. But it is major surgery followed by a lifetime of medication, so the decision rests on medical suitability, donor availability and the family's ability to sustain follow-up care.
A transplant is considered when a patient has advanced kidney failure, is otherwise healthy enough for surgery, and has — or can realistically obtain — a suitable kidney. People with active serious infection or advanced heart disease may not be eligible; the transplant team reviews each case individually.
The evaluation process
Evaluation is deliberately thorough — it protects both the recipient and the donor. Expect to spend several visits and to undergo a coordinated set of tests:
- Blood group and tissue typing — to establish compatibility between recipient and donor.
- Heart, lung and general health checks — to confirm you can safely undergo surgery.
- Infection screening — for infections that could worsen under immunosuppression.
- Psychological and social assessment — to confirm you understand lifelong medication and can sustain it.
- Donor evaluation — a completely separate and equally rigorous process for any living donor, including an independent counsellor so that consent is truly voluntary.
The evaluation may reveal a reason to delay or decline transplant — for example, an infection that needs treating first. Finding that before surgery is a success of the process, not a failure.
Two compatibility tests deserve special mention because families hear the words quickly but understand them slowly. HLA (tissue) typing compares the genetic markers by which your immune system recognises matching tissue — the closer the match between recipient and donor, the lower the risk of rejection. The cross-matchmixes a sample of your blood with the donor's cells to check whether your immune system would already attack the donated kidney; a positive cross-match usually rules out that particular donor. When a near relative cannot donate, options such as the swap of kidneys between two incompatible pairs — running within the framework of authorised transplant rules — exist at some centres and are worth asking about.
Living and deceased donors
Kidneys come from two sources. A living donor is a healthy person who volunteers to donate one of their two kidneys — most commonly a close relative. Deceased donation happens when a person who has died, typically from brain death, has their organs shared through an authorisation system.
Living donor transplants tend to have the best outcomes because the kidney is healthy, the surgery is planned, and the waiting time is short. In India, where deceased donation is far below the need, living donation is the route taken by most families — which is exactly why the law protects donors so carefully.
A living donor must be thoroughly evaluated, must not be paid, and can withdraw from the process at any point without pressure. The decision to donate must come freely from the donor, never from family obligation dressed up as love.
The law in India
Transplantation in India is governed by the Transplantation of Human Organs and Tissues Act (THOTA). Its core principles are simple: donation must be voluntary, commerce in organs is a crime, and near relatives — parents, children, siblings and spouses — receive priority for living donation.
Every living transplant case is reviewed by a hospital authorisation committee before surgery, and non-near-relative cases go to the state-level authorisation committee. This dua- layer scrutiny exists to stop unethical trade and to protect donors from exploitation.
Deceased donor organs are matched and shared through national and regional networks (adapted under NOTTO and the state registries). Donation after death remains the law's strongest hope for closing India's enormous transplant gap — registering as a donor, and telling your family, is one of the most powerful choices an Indian family can make.
The transplant surgery
Donor nephrectomy — removal of the donated kidney — is usually a minimally invasive procedure today, meaning smaller incisions and a faster recovery for the donor. The recipient's operation places the new kidney in the lower abdomen and connects it to blood vessels and the bladder. The failed native kidneys are usually left in place.
The surgery itself typically takes three to six hours. Many recipients begin producing urine immediately — a powerful moment that marks the kidney's new life. The hospital stay afterwards is usually about a week, during which the immune-suppressing medicines are stabilised and the kidney's function is checked daily.
Recovery and follow-up
The first year after transplant is the most demanding. Follow-up is frequent — initially weekly, then gradually spread out — with regular blood tests to watch kidney function and medication levels. Most patients return to normal daily activity within a couple of months and to work within a few months, depending on the job.
The immune-suppressant medicines that protect the kidney also lower resistance to infection, so hand hygiene, vaccinations and avoiding sick contacts matter more than before. Healthy food, salt awareness, and blood pressure control all directly protect the transplant. None of this is exotic — it is a disciplined version of ordinary healthy living.
Diet after transplant reverses much of the dialysis-era restriction: many foods return, but salt remains the quiet enemy, and protein needs are usually normal rather than high. Most teams recommend regular light exercise — a daily walk is the classic benchmark — and weight control, because weight gain and diabetes are the two long-term problems transplant patients most often face under long-term steroids. Vaccinations matter too: certain vaccines are given before transplant, others are postponed until after, and the transplant team keeps your schedule. If you ever feel unwell, particularly with fever, do not wait for a routine visit — report it the same day, because early infection treatment is what keeps a transplant alive.
Risks, and how they are managed
No transplant is free of risk, and a balanced guide should say so. The main risks are:
- Rejection— the body's immune system attacking the new kidney. It is detected early through blood tests and usually treatable by adjusting medication.
- Infection — more likely under immunosuppression; managed with prevention, vaccination and prompt treatment.
- Surgical complications — bleeding, clotting, or problems with the bladder connection, generally managed by the surgical team.
- Medication side effects — long-term effects on blood pressure, sugars and bones are monitored with routine checks.
The single most common cause of a transplant failing years later is stopping medication. The most valuable habit a transplant patient can build is never skipping a dose and never missing a follow-up visit.
Costs and financing
Cost is the question Indian families ask first and answer last. Kidney transplant costs in India are widely reported to range somewhere between roughly ₹5 lakh and ₹15 lakh for the surgery and initial care, with significant variation by city, hospital, donor evaluation, medicines and how long after discharge care continues. Long-term immunosuppressants are a continuing expense that must be budgeted for.
Several financing routes can help: private health insurance policies that cover transplant and immunosuppressant coverage, employer and corporate insurance pools, and government schemes such as Ayushman Bharat for eligible families in participating states, plus state-specific health schemes and welfare funds.
The honest advice: get written estimates from the hospital, and confirm precisely which of your tests and medicines are covered before you begin. Our insurance and schemes guide takes you through this in detail.
Remember that the cost picture includes more than the surgery. The donor's evaluation and the donor's surgery have their own costs. Anti-rejection medicines in the first year are among the most expensive items on the bill, and they continue, at a lower level, for life. A transplant is therefore best thought of as a budget for care over years, not a single payment — plan the follow-up budget with the same seriousness as the surgery itself, and ask the hospital for a projected one-year and five-year cost picture before you commit.
Deciding together as a family
In India, kidney disease is a family diagnosis, not a personal one. Decisions about dialysis, donation and surgery involve parents, children, spouses and sometimes the whole extended family. That can feel overwhelming — but it also means treatment is far more likely to succeed when everyone understands it.
Practical steps that reduce conflict: bring two people to key consultations so nothing is misremembered; write your questions down before visits; keep a single file of all reports; and give the donor candidate space to decide freely — a pressured donor is a danger to the whole plan.
This guide, and the rest of this site, exists to give you the information that makes those family conversations calmer and more equal.
