Kidney Transplant in India for International Patients

An international patient seeking a kidney transplant in India must bring a relative as a living donor, with the relationship proved by DNA testing and verified by the embassy. Blood group and tissue compatibility are established, and incompatible pairs can often still proceed. At BLK-Max Super Speciality Hospital, New Delhi, Dr. Y P S Rana put the routine transplant package at about USD 13,000 to 14,000 in November 2025.

Dr. Yajvender Pratap Singh Rana, Senior Director - Urology, Uro-Oncology, Andrology and Kidney Transplant, BLK-Max Super Speciality Hospital, New Delhi, India, walked doctors from across Africa through every step of that pathway, from the first creatinine test to the night a deceased-donor kidney becomes available. This article follows the same sequence. It belongs to a series that starts with advances in urology, uro-oncology and kidney transplant; what happens after the operation is covered in life after a kidney transplant.

Why kidney failure is rising, and why it is caught late

Kidney failure is a rapidly growing problem, driven by diabetes, hypertension, heart disease and obesity. Dr. Rana's starting point for referring doctors is that kidneys are silent organs. By the time a patient has symptoms of kidney failure, it is too late.

His recommendation is a simple annual screen for everyone: serum creatinine, a urine examination including protein, and an ultrasound. Ultrasound is simple and informative. It shows the size of the kidneys, and on routine scans his team sometimes picks up kidney tumours early enough to cure them with a simple operation.

He also spoke to the human side. The day a patient is told the kidneys have failed and dialysis or transplant is needed is "the day of doom" for the family, and for the doctor too. The first challenge is acceptance, and family, society and clinicians all have a role in counselling, explaining the numbers and showing the patient that they are not alone.

Who should have a kidney transplant

Clinical triggers for renal replacement therapy

Dr. Rana listed the markers that tell him a patient's kidneys will not recover and renal replacement therapy (dialysis or transplant) must begin:

• serum creatinine above 7 mg/dL;
• symptoms and signs of fluid overload;
• hyperkalaemia (a dangerously high blood potassium);
• shrunken kidneys on ultrasound;
• falling urine output;
• parathyroid hormone (PTH) above the normal range.

Shrunken kidneys and a raised PTH mainly signal that the disease is chronic. Guidelines time the start of dialysis by symptoms and complications, such as fluid overload, high potassium, acidosis or uraemic symptoms, usually when kidney function (eGFR) has fallen to about 5 to 10 mL/min, rather than by a creatinine threshold alone, and a transplant done before dialysis is needed gives the best results.

Kidney transplant age limit: physiology over the calendar

Transplant is always better than dialysis for a suitable patient. Dialysis patients, in Dr. Rana's description, lead a miserable life: two or three sessions a week, frequent hospital visits and never free of their kidney problem. After a transplant they take their immunosuppressive medicines and enjoy a good quality of life.

Suitability, however, depends on age. Transplant is the best modality up to about 60 and a good one below 70. Above 80, his team generally declines, even when an older patient has the money and a willing donor, because heavier immunosuppression brings more complications. He made the distinction between chronological and physiological age explicit: an 80-year-old who is fully fit and active, has a donor and is not immunocompromised can still be considered. As a rule of thumb, though, transplant is not the best option above 80, and such patients are better kept on dialysis. "We are not offering transplant for each and everyone," he said; selecting recipients well is what makes transplants succeed and gives each donated kidney its best chance.

Preparing the patient at home

Dialysis access

The first practical step is dialysis access, because patients are stabilised on haemodialysis while the transplant is arranged. An arteriovenous fistula, a surgical connection between an artery and a vein in the arm, is created so that the vein enlarges and delivers the high blood flow a dialysis machine needs.

Continuous ambulatory peritoneal dialysis (CAPD), through a catheter in the abdomen, is the alternative. Patients can manage their exchanges at home, but any breach in sterility risks infection, and these infections can be very dangerous.

The referral sequence

Dr. Rana's advice to doctors in Africa is to stabilise the patient on haemodialysis, start looking for a donor within the family in the meantime, and then plan travel. The hospital's international team helps with the visa process and coordinates the visit from arrival to discharge.

The law on kidney transplant for international patients

Under Indian law, foreign nationals may receive a kidney only from a living related donor. Near relatives under the Transplantation of Human Organs and Tissues Act are the spouse, parents, children, brothers and sisters, grandparents and grandchildren. The rule of thumb Dr. Rana applies:

1. Close family first: husband or wife, parents, children, brothers and sisters, and grandparents.
2. DNA proof of relationship. Every donor and recipient pair undergoes DNA testing to confirm the relationship and the family tree.
3. Embassy verification. The patient's embassy checks and verifies the relationship and the documents.

Cousins and other relatives beyond the near-relative list also qualify as related donors, but their donation must be approved by the hospital or state Authorisation Committee. In his hospital's practice, which he described for Indian and international donors together, extended family is considered when nobody in the near family can donate, and two or three DNA tests may be needed to establish the relationship.

"No transplant we do without their having a DNA match and with the confirming their relationship," he said. Under the Transplantation of Human Organs and Tissues Rules, transplants involving foreign nationals also require approval from an authorisation committee before surgery. For Indian citizens, both living related and deceased-donor transplants are performed routinely.

Screening the family for a donor

Donor screening happens in two levels, and much of it can be done at home before anyone travels.

Level 1, available almost everywhere:

• complete blood count (CBC);
• kidney function tests;
• blood group;
• blood sugar;
• ultrasound of the whole abdomen;
• urine routine examination and urine culture.

Level 2, if level 1 is normal, both kidneys look healthy and blood sugar is normal:

• DTPA renal scan, which measures the function of each kidney separately;
• CT urography or CT renal angiography, which map the urinary tract and the blood vessels;
• a crossmatch, if available.

Where level 2 tests are not available locally, Dr. Rana's team asks for the ultrasound and basic results; if they are good, the patient and donor travel and the remaining investigations are done at BLK-Max.

Blood group compatibility and ABO-incompatible transplant

The preferred donor is blood-group compatible. An A recipient can receive from an A or an O donor; a B recipient from a B or an O donor.

When the blood groups do not match

ABO-incompatible transplant is performed routinely at BLK-Max, but Dr. Rana was clear that it is the second choice, used only when no compatible donor exists in the family. The principle rests on antibodies: a recipient with blood group B carries antibodies against group A, which would attack a group A kidney. If those antibodies are reduced to a very low level before surgery, they do not damage the graft.

The key measurement is the anti-blood-group antibody titre, chiefly IgG, which matters most for transplant. Dr. Rana's thresholds:

Once the titre has been brought back down to the acceptable range of 1:8 or below, the transplant proceeds.

Plasmapheresis removes antibodies by filtering the patient's plasma. Immunoadsorption passes the plasma through a column that binds the specific blood-group antibodies.

The protocol is distinct from a standard transplant. Titres are checked 15 days before surgery and the anti-CD20 antibody rituximab is given at that point. Two or three days before surgery, plasmapheresis begins and titres are checked daily. Some patients show a rapid rebound in titres and need plasma filtration around the clock; the patient goes to theatre when the titre is at an acceptable level.

The trade-off is real. Results are slightly lower than with a compatible transplant, and hyperacute rejection, though rare, does occur in ABO-incompatible transplants; Dr. Rana put it at about one in 50 patients.

HLA matching and the crossmatch

Human leucocyte antigens (HLA) are the tissue-type proteins the immune system uses to recognise "self". A low HLA match between donor and recipient is not, in Dr. Rana's words, "a big problem": husbands and wives sometimes share no HLA match at all and still receive successful transplants. What matters is whether the recipient already has antibodies against the donor's HLA.

That is tested with crossmatches:

1. CDC crossmatch (complement-dependent cytotoxicity): the recipient's serum is tested against the donor's cells.
2. Flow cytometry crossmatch: a more sensitive test of the same question.

If both are negative, the case is good and the transplant proceeds. If CDC is negative but flow is positive, more sophisticated testing follows: donor-specific antibody (DSA) levels measured by single antigen bead assay, reported as mean fluorescence intensity (MFI). Low antibody levels are acceptable, an MFI up to about 1,500 to 2,000 in Dr. Rana's practice; higher levels are brought down with plasmapheresis before surgery. The cut-off values used vary between laboratories.

Kidney transplant for recipients with HIV or hepatitis

HIV-positive patients can receive a kidney transplant. Dr. Rana answered "with authority": his team has transplanted many HIV-positive patients, and they do fairly well. Preparation starts at home. His team stays in contact with the local doctor, who keeps the patient under good medical care until the CD4 count shows the patient is fit for transplant; only then is the patient asked to travel. Immediate surgical risks are the same as in other recipients, but later infection-related complications are more frequent, so immunosuppression is gentler. Instead of routine induction with ATG (anti-thymocyte globulin, a potent antibody that depletes T cells), these patients may be induced with basiliximab, which suppresses immunity less.

Patients with hepatitis B or C, common among people on dialysis because the infections can be transmitted through dialysis machines, are also transplanted. Effective antiviral medicines exist for both; once the viral parameters are in a safe range, the transplant goes ahead and the patient continues antiviral treatment afterwards.

Deceased-donor kidney transplant and NOTTO

Deceased-donor (cadaveric) transplant is close to Dr. Rana's heart, and he sees it as the way to close the gap between supply and demand. In Delhi NCR the process is coordinated by NOTTO, the National Organ and Tissue Transplant Organisation.

1. A hospital with a brain-dead patient informs NOTTO.
2. A panel of doctors, including the treating doctor and a specialist such as a neurointensivist, neurosurgeon or anaesthetist, certifies brainstem death. The tests are performed twice; for adults, the Transplantation of Human Organs and Tissues Rules require an interval of at least six hours between the two sets.
3. The family gives consent for donation of organs such as kidneys, liver, corneas and heart.
4. NOTTO allocates each organ from a central waiting list, by turn. A hospital cannot simply use a kidney from its own donor for its own patient.
5. The receiving team calls in its waiting-list patient, dialyses them and runs the crossmatch, with the report back within about six hours.
6. If the crossmatch is negative, a surgical team retrieves the kidney at the donor hospital while the recipient is prepared in parallel.

Dr. Rana described it as an overnight, roughly 12-hour process in which everything happens simultaneously, to keep the time the kidney spends outside the body as short as possible.

The operation: mini-incision and robotic transplant

After retrieval, the kidney is perfused to clear clotted blood and transplanted into the iliac fossa, the lower abdomen just above the groin. The recipient's own kidneys are usually left in place. Only one kidney is transplanted, and native kidneys are removed only when they pose a risk of infection, such as very large kidneys containing stones.

Dr. Rana's routine operation is a mini-incision transplant through a wound of only 8 to 9 cm, using a special retractor and magnification for precise vascular anastomoses (the joins between the donor and recipient vessels). For very obese patients with good vessels, and for those concerned about the scar, his team performs robotic kidney transplant routinely; the vein is joined first, then the artery. Robotic transplant has its own dedicated series, robotic kidney transplant: a complete guide.

Kidney transplant cost in India and donor safety

What it costs

Dr. Rana put the routine mini-incision transplant package at BLK-Max at about USD 13,000 to 14,000. A robotic transplant costs about USD 3,000 more. He described the hospital's transplant packages as nominal, and much cheaper than the costs he has seen while mentoring centres in Africa, including in Ghana: even after travel and their stay, patients save money. Current indicative prices are on the robotic kidney transplant cost page.

Is donation safe for the donor?

The question families ask most is whether the donor, left with one kidney, is at risk. Dr. Rana's answer begins with selection: the workup is so thorough that any donor with a problem in the kidneys or elsewhere is refused. In his experience, donors are healthier than their peers and live a happy life, helped by the pride of having saved a family member. Long-term studies show that carefully selected living donors have survival at least equal to that of the general population, although their lifetime risk of kidney failure is slightly higher than that of equally healthy people who did not donate.

The workup itself sometimes helps the donor. In one case, a prospective donor had mild hydronephrosis caused by a small stone and a narrowing of the upper ureter that he had ignored for a long time. The team removed that kidney, cleared the stone, corrected the narrowing and transplanted it, leaving the donor with his normal kidney.

Asking a relative to donate

Asked how to find a living donor ethically, Dr. Rana agreed that a donor cannot be pressured. His opening line to potential donors is that donation is "a chance to become more healthier". When no willing donor exists, the recipient should remain on dialysis rather than a relative being pressed to donate. He also urged doctors to promote deceased-donor pledging, starting with a simple message: look after your own health first, and if the worst happens, do not hesitate to share your organs.
