AI Overview / Quick Answer (BLUF)

A transplanted kidney filters continuously (eGFR about 45–70); dialysis replaces ~10–15% of normal clearance, so fluid, blood pressure and toxins are better controlled.
Recipients’ long-term mortality is 48–82% lower than waitlisted dialysis patients’; living-donor kidneys last longest, and screened donors face low but non-zero risk.

What this page covers, and what to read alongside it

A common family situation

“Mum has been on dialysis for 5 years. She tires easily and her mood has changed. Her son wants to donate a kidney, but she refuses because she is afraid something will happen to him.” — an illustrative scenario summarized from common questions

Three questions are layered here: is a transplant really better than dialysis, how safe is the donor, and how can the family talk without anyone feeling pressured or guilty.
This page answers all three with research numbers and corrects common overstatements such as “a transplant restores 100% kidney function” or “the enlarged heart returns to normal.”

1. The direct answer: living-donor transplant vs long-term dialysis

Direct answer: for people fit for surgery, a kidney transplant offers longer survival and better quality of life than long-term dialysis,
and a kidney from a living donor gives the best results, because surgery is scheduled, the kidney is without blood flow only briefly, and it can often be done before years of dialysis.
The trade-off is lifelong immunosuppression, and the donor accepts a risk that is low but real.
(Tonelli M, Am J Transplant 2011;
Poggio ED, Am J Transplant 2021)

  • Survival: recipients have 48–82% lower long-term mortality than patients who stay on dialysis while waitlisted
  • Kidney function: one graft typically gives an eGFR of about 45–70 — not 100%, but many times more than dialysis
  • Graft lifespan: living-donor kidneys last a median of about 19.2 years versus about 11.7 years for deceased-donor kidneys (estimates for 2014–2017 transplants)
  • Donor: surgical mortality about 3.1 per 10,000; long-term kidney-failure risk is higher than for healthy non-donors but still lower than the general population
  • Family: donation must be the donor’s free choice, withdrawal is possible at any time, and the team will not tell the recipient why

2. Why long-term dialysis strains the heart and changes mood and personality

Direct answer: dialysis saves lives, but it works intermittently rather than continuously like a real kidney, so water, salt, and waste rise and fall in a saw-tooth pattern between sessions.
The heart absorbs these swings in pressure and volume every week for years, on top of anemia, high blood pressure, and uremic toxins that dialysis does not fully remove.
(NIDDK — Choosing a Treatment for Kidney Failure)

The filtration gap: dialysis replaces only part of a kidney

A healthy kidney works 168 hours a week, while standard hemodialysis is 3 sessions a week of about 4 hours each (about 12 hours).
Averaged over a week, dialysis therefore provides only roughly 10–15% of normal kidney clearance (an approximate figure commonly cited in clinical practice),
and it does not replace the kidney’s hormonal work, such as producing the hormone that stimulates red blood cells and activating vitamin D.

Left ventricular hypertrophy (LVH): the cumulative effect of fluid, pressure, and anemia

In a study of 433 patients starting kidney replacement therapy, echocardiography found
left ventricular hypertrophy in 74%,
left ventricular dilatation in 32%, and clinical heart failure in 31% on the first day of dialysis — anemia, wide pulse pressure, and low albumin were linked to these abnormalities.
(Foley RN, Kidney Int 1995)

  • Fluid build-up between sessions — the heart pumps a larger volume, so its wall thickens and its chambers enlarge
  • High blood pressure and stiff arteries — from salt, water, and vascular calcification common in kidney failure
  • Anemia — the heart beats faster and harder to deliver enough oxygen
  • The 2-day gap between sessions (for example Friday to Monday) is linked to mortality of 22.1 vs 18.0 per 100 person-years on the day after the long gap
    (Foley RN, N Engl J Med 2011)

Depression, fatigue, and “not the same person anymore”

A review of 249 populations (55,982 people) found interview-confirmed depression in 22.8% of people on dialysis — about 1 in 4 —
and depressive symptoms in up to 39.3% when screening questionnaires were used
(Palmer S, Kidney Int 2013).
Families often notice irritability, withdrawal, not wanting to leave home, or burnout, which arise from several factors together:

  • Residual uremic toxins, anemia, and poor sleep cause fatigue and poor concentration
  • Post-dialysis exhaustion that leaves some people resting for hours, costing work days and social life
  • A sense of lost control: a fixed dialysis schedule, fluid and diet limits, and difficulty travelling
  • Feeling like a burden on the family — the same root as the guilt that surfaces when someone offers a kidney (section 6)

Depression is treatable and worth telling the kidney team about — a clinical interview is more accurate than a questionnaire alone.

3. Why a transplant is the best long-term option (for suitable patients)

Direct answer: a transplanted kidney works continuously, 24 hours a day — filtering waste, balancing water and minerals, and making hormones.
The result is longer survival, better quality of life, and fewer cardiovascular events compared with dialysis in similar patients.
(NIDDK — Kidney Transplant)

Survival: numbers from large registries

Among 228,552 dialysis patients, transplant recipients had 48–82% lower long-term mortality than patients who stayed on dialysis while waitlisted.
Risk was temporarily 2.8 times higher in the first 2 weeks after surgery, but by 18 months the relative risk had fallen to 0.32
(Wolfe RA, N Engl J Med 1999).
A review of 110 studies (1,922,300 people) found that most showed lower mortality, fewer cardiovascular events, and clearly better quality of life with transplantation
(Tonelli M, Am J Transplant 2011).

Note: the Wolfe data come from deceased-donor kidneys, and waitlisted patients are already healthier than the average dialysis patient; comparing against waitlisted patients reduces part of this bias.

A graft does not work at “100%” — and it does not need to

The claim that “a transplant restores almost 100% of kidney function” is not accurate. One graft typically gives an eGFR of about 45–70 mL/min/1.73 m²,
equivalent to transplant CKD stage 2–3 (CKD 2–3T), because there is only one working kidney, it went through a period without blood flow during surgery, and calcineurin inhibitors affect blood vessels in the kidney.
That level is still many times more than dialysis and enough to live without dialysis.

The heart after transplant: partial improvement, not always a return to normal

In 143 recipients with yearly echocardiograms, left ventricular mass index fell from 161 to 146 g/m² between years 1 and 2 and then plateaued in years 3–4;
older age, long-standing hypertension, and needing several blood pressure medicines were linked to less regression
(Rigatto C, Transplantation 2000).
A cardiac MRI study (more accurate than echocardiography in kidney patients) comparing 25 transplant recipients with 25 patients on dialysis found no significant reduction in heart mass
(Patel RK, Clin J Am Soc Nephrol 2008).

  • Keep blood pressure at the target your team sets, and check it at home
  • Check anemia, lipids, glucose, and weight regularly — post-transplant diabetes is common with immunosuppressants and steroids
  • Do not smoke, and exercise as your team allows — cardiovascular disease remains a leading cause of death with a functioning graft
    (Hariharan S, N Engl J Med 2021)

Why living-donor kidneys last longer

Data from 331,216 adult US kidney transplants (1995–2017) estimated median graft survival for 2014–2017 transplants at
about 19.2 years for living-donor kidneys versus about 11.7 years for deceased-donor kidneys
(Poggio ED, Am J Transplant 2021).
Living donors are thoroughly screened for healthy kidneys, the kidney is without blood flow only briefly, and surgery can be scheduled when the recipient is at their best.

Transplant before dialysis (pre-emptive) is best

Among 38,836 first transplants, living-donor transplantation before starting dialysis was linked to a lower risk of graft failure (relative risk 0.73)
and a lower risk of death (0.69) compared with transplantation after dialysis had begun
(Kasiske BL, J Am Soc Nephrol 2002)
— families with a potential donor should start evaluation from CKD stage 4 rather than waiting for dialysis.

The trade-offs: lifelong immunosuppression and new risks

  • Daily immunosuppressants for life — usually a calcineurin inhibitor (such as tacrolimus) plus mycophenolate and corticosteroids, with regular blood-level checks
    (KDIGO Transplant Recipient 2009)
  • Rejection — can happen at any time, especially in the first year or with missed doses; most episodes are treatable if caught early
  • Infections — such as CMV, BK virus that can damage the graft, and PJP pneumonia
    (Fishman JA, N Engl J Med 2007)
  • Post-transplant diabetes, high blood pressure, high lipids, and bone thinning
  • Skin cancer and some other cancers become more common — use sunscreen daily and attend skin checks
  • Not everyone is suitable — for example active cancer, severe uncorrectable heart disease, uncontrolled infection, marked frailty, or not yet being ready to take medicines consistently

4. Five options compared in one table

Direct answer: kidney failure has 5 main paths — hemodialysis, peritoneal dialysis, living-donor transplant, deceased-donor transplant, and conservative care without dialysis. This table compares what families ask about most.
(NIDDK — Choosing a Treatment)

Comparison table: hemodialysis vs peritoneal dialysis vs living-donor transplant vs deceased-donor transplant vs conservative care

OptionSurvivalKidney function achievedDiet and fluid limitsTime burdenMedicinesMain risksQuality of life
Hemodialysis (HD)Similar to PD; lower than transplant recipients with similar characteristicsRoughly 10–15% of normal clearance averaged over a week (approximate); no hormonal functionStrictest: fluid about 500–1,000 mL/day plus urine output; limit potassium, phosphate, and salt3 sessions/week of about 4 hours + travel + post-dialysis fatiguePhosphate binders, red-cell-stimulating agents, iron, blood pressure medicinesLow blood pressure during sessions, access narrowing or infection, fluid and potassium build-up, heart enlargementConstrained by the schedule; depression in about 1 in 4

5. Living-donor safety: the real numbers

Direct answer: kidney donation by a screened donor is low-risk, but not zero-risk. Doctors do not use a “1% rule” or any single number;
they estimate each donor’s lifetime risk and exclude people with diabetes, uncontrolled hypertension, low filtration, proteinuria, or significant stones
(Lentine KL, KDIGO Living Donor 2017).

Donor evaluation: what is tested, and what counts as safe

Evaluation usually takes several weeks to several months, and the donor should have a team or doctor looking after the donor’s interests, separate from the recipient’s team.

Donor evaluation table: step → tests → safety threshold → long-term effect on the donor

Evaluation stepTestsSafety threshold (typical)Long-term effect on the donor
CompatibilityABO blood group, HLA tissue typing, and crossmatchCrossmatch must be negative; some centres can manage blood-group incompatibility with special protocolsNo effect on the donor’s health
Kidney functionCreatinine, eGFR, and measured GFR when neededGFR of 90 or more acceptable; below 60 generally declined; 60–89 decided case by caseThe remaining kidney compensates; filtration usually recovers to about 60–70% of baseline; at 12.2 years, 85.5% still had GFR of 60 or more
Urine protein/albuminAlbumin excretion rate or albumin-to-creatinine ratioBelow 30 mg/day acceptable; above 100 mg/day declined; 30–100 decided case by caseAlbuminuria in 12.7% at 12.2 years; recheck every year
Blood pressureRepeated readings or 24-hour ambulatory monitoringUncontrolled hypertension or organ damage declined; mild hypertension controlled with 1–2 medicines considered at some centresHypertension in 32.1% at 12.2 years, similar to people of the same age; measure yearly
Diabetes and metabolic healthFasting glucose, HbA1c, glucose tolerance in some, body mass indexDiabetes usually declined; severe obesity (for example BMI above 35) declined at many centresWeight gain after donation raises the risk of hypertension and kidney decline — manage weight for life
Anatomy and stonesCT angiography and kidney imagingBilateral or recurrent stones, or suspicious masses, usually declined; the better kidney stays with the donorDrink enough and limit salt to prevent stones in the single kidney
Cancer and infectionHIV, hepatitis B and C, age-appropriate cancer screeningActive cancer or infection transmissible to the recipient declinedA thorough health check; some find treatable conditions early
Psychosocial review and consentAssessment by a psychologist, social worker, or doctor independent of the recipient’s teamVoluntary, informed, free of pressure and payment, and free to withdraw at any timeMost donors report quality-of-life scores better than population norms
Future pregnancyCounselling for women of childbearing age before donationNot a contraindication, but the higher preeclampsia risk must be understoodGestational hypertension or preeclampsia 11% vs 5%
Lifelong follow-upBlood pressure, creatinine or eGFR, urine albumin, weightAt least once a year for lifeEstimated lifetime kidney-failure risk about 90 per 10,000

Thresholds summarized from KDIGO Living Donor 2017; long-term effects from Ibrahim 2009, Muzaale 2014, and Garg 2015 — individual transplant centres may be stricter.

Short- and long-term risk: read both sides of the numbers

  • Surgical mortality: about 3.1 per 10,000 among 80,347 US donors, with long-term survival (median follow-up 6.3 years) no different from matched healthy people
    (Segev DL, JAMA 2010)
  • End-stage kidney disease at 15 years: 30.8 per 10,000 donors versus 3.9 per 10,000 matched healthy non-donors — higher in relative terms, but small in absolute terms
    (Muzaale AD, JAMA 2014)
  • Norwegian data (1,901 donors, median follow-up 15.1 years) compared with people who would have been eligible to donate found slightly higher mortality (HR 1.30) and higher end-stage kidney disease risk, though overall incidence stayed low (302 per million) and may partly reflect family heredity
    (Mjøen G, Kidney Int 2014)
  • Minnesota data (3,698 donors): survival similar to controls; kidney failure 180 per million per year versus 268 in the general population
    (Ibrahim HN, N Engl J Med 2009)

Estimated lifetime risk of end-stage kidney disease (per 10,000 people)

Source: Muzaale 2014 — donors carry more risk than healthy non-donors but less than the general population, because donors are screened. Risk is higher for younger donors and those with a family history of kidney disease.

Pregnancy after donation

An Ontario, Canada study comparing 85 female donors (131 pregnancies) with 510 healthy women found gestational hypertension or preeclampsia in 11% vs 5% (odds ratio 2.4),
while preterm birth (8% vs 7%) and low birth weight (6% vs 4%) were not significantly different, and most pregnancies were uncomplicated
(Garg AX, N Engl J Med 2015).
Donors who become pregnant should tell their obstetrician at the first antenatal visit.

How donors should look after themselves for life

  • Check at least once a year: blood pressure, creatinine or eGFR, urine albumin, and weight
  • Avoid regular NSAID painkillers without medical advice, and tell every doctor you have one kidney, especially before contrast scans
  • Do not smoke, manage weight, limit salt, and exercise regularly — discuss heavy-contact sports with your doctor
  • In many countries, former donors who later develop kidney failure receive waitlist priority — ask your Thai transplant centre about its policy

6. Family psychology: recipient guilt vs family worry

Direct answer: recipient guilt and family worry are normal and should not be suppressed. The solution is a process that makes
the decision genuinely the donor’s — evaluating the donor separately from the recipient, involving an independent advocate for the donor, and allowing withdrawal without anyone losing face
(Dew MA, Am J Transplant 2007;
KDIGO 2017).

Why recipients feel guilty

  • Parents do not want a child to “take a risk for me” — they feel their role is to protect, not to receive
  • Years of feeling like a burden on dialysis make guilt build on itself
  • Fear that if the graft fails, the donor’s sacrifice will have been “wasted”

Depression does not disappear in everyone after transplant — the same review found interview-confirmed depression in about 25.7% of kidney transplant recipients (Palmer 2013), so emotional care should continue before and after surgery.

Donor autonomy: design the process so withdrawal is real

  • Separate evaluation — the donor should speak with the team without the recipient or other relatives in the room
  • An independent living donor advocate, or a doctor, psychologist, or social worker who does not care for the recipient — ask whether your centre has one
  • Confidential opt-out — many centres tell the family only that “the donor is not medically suitable,” without giving reasons, so the donor is not pressured
  • Time to think — nobody should have to agree on the day they first hear the information, and the donor can change their mind up to the day of surgery
  • No money or other rewards — organ trading is illegal and unethical

How to talk as a family: phrases that help

  1. The recipient opens the door both ways: “Thank you for thinking of me. I want you to hear the information from the donor team yourself, and if you change your mind, I will never ask why.”
  2. The donor states their own reasons: “I chose this myself after hearing the risks, not because anyone asked me.”
  3. Talk about fears using numbers — read section 5 together instead of guessing or relying on stories
  4. Separate “can the surgery be done?” from “do I want to do it?” — the medical team answers the first; the second is the donor’s right
  5. See a psychologist together if conversations turn into arguments or tears, or other relatives apply pressure

The recipient’s role: turn guilt into caring for the graft

  • Take immunosuppressants on time, every dose — inconsistent medicine-taking is an important cause of late rejection
  • Attend every blood test, even when you feel well, because early rejection is often silent
  • Look after the donor in return: go with them to annual checks, and build healthy habits as a household
  • See the kidney as a gift to care for, not a debt to repay — this feeling is worth exploring with a psychologist

7. Life after a kidney transplant: the first year, rejection signs, infection, and lifelong medicines

Direct answer: the first year matters most — visits are frequent, immunosuppressant levels are highest, and the risks of rejection and infection peak. Visits then space out, but immunosuppressants and blood tests continue for life
(KDIGO Transplant Recipient 2009).

First-year timeline

  1. Week 1In hospital: urine output, creatinine, and the wound are monitored; living-donor kidneys usually start working immediately
  2. Months 1–3Frequent blood tests (often 1–2 times a week at first), tacrolimus level adjustments, PJP and CMV prevention according to risk; avoid crowds and heavy lifting
  3. Months 3–6Visits space out and many people return to light work; BK virus and CMV monitoring according to the centre’s plan
  4. Months 6–12Visits about every 1–2 months; glucose, lipid, and blood pressure checks; plan inactivated vaccines as the team advises (avoid live vaccines)
  5. After year 1Visits every 1–3 months for life; skin checks and age-appropriate cancer screening; women hoping to conceive should plan with the team first → pregnancy after kidney transplant

Signs of rejection

  • Usually no symptoms — found by rising creatinine on blood tests, so never skip appointments
  • If symptoms occur: less urine, swelling, rapid weight gain, rising blood pressure, fever, or tenderness over the graft
  • Doctors usually confirm with a kidney biopsy, and most episodes respond to adjusted immunosuppression if caught early

Infection: largely preventable with hygiene and follow-up

Lifelong medicines: rules not to break

  • Take immunosuppressants at the same time every day, set alarms, and never stop or reduce doses yourself
  • On tacrolimus level days, have blood drawn before the morning dose as your team instructs
  • Tell the team before starting any new medicine, including antibiotics, antifungals, herbs, and supplements — many raise or lower drug levels; avoid grapefruit
  • Immunosuppression raises skin-cancer risk — use sunscreen, wear long sleeves, and attend skin checks
  • Hair loss after transplant → severe hair loss after kidney transplant: causes and what to do

8. The Thailand context: who can donate, coverage, and the deceased-donor list

Direct answer: under Medical Council of Thailand criteria, a living kidney donor must be a blood relative or a legally married spouse of at least 3 years (or less if the couple has a child together),
and organ trading is prohibited — details may be updated, so confirm with the transplanting hospital.

  • People without a living donor register for a deceased-donor kidney with the Thai Red Cross Organ Donation Centre through a transplanting hospital → preparing once you are on the waiting list
  • The main schemes — Universal Coverage, Social Security, and civil servant benefits — include kidney transplant and post-transplant immunosuppressants under each fund’s conditions; check with the hospital or the NHSO hotline 1330
  • Ask the transplant centre early which scheme pays for donor evaluation, surgery, and long-term donor follow-up, and how long the donor needs off work (often about 4–6 weeks for physical jobs)
  • Ask your nephrologist for transplant referral from CKD stage 4 if a relative may donate, so a transplant before dialysis is possible

The living-donor transplant pathway in 5 steps

The donor can withdraw at every step — right up to the day of surgery

Scientific mechanism (synthesized by the author)

Synthesized by
:
a healthy kidney filters about 180 litres of blood a day through roughly 1 million nephrons per kidney, adjusting water and mineral reabsorption minute by minute.
Hemodialysis works only intermittently, so waste and water accumulate between sessions and are then removed quickly over a few hours. Repeated swings in blood volume, high blood pressure, anemia, and arterial stiffening from calcium-phosphate deposition
expose the left ventricle to both pressure overload and volume overload, so the heart muscle thickens, develops fibrosis, and becomes prone to arrhythmia.
After transplant, the new kidney filters continuously, regulates water and salt on its own, produces erythropoietin, and activates vitamin D, so anemia and fluid overload improve.
But myocardial fibrosis and arteries that have already stiffened reverse only partly, while calcineurin inhibitors and corticosteroids can raise blood pressure, glucose, and lipids —
which is why heart mass falls by different amounts in different people.
On the donor side, with one kidney left, the remaining nephrons enlarge and filter more per nephron (hyperfiltration), so total filtration recovers to about 60–70% of baseline.
In healthy kidneys this adaptation can stay stable for decades, but added factors such as obesity, hypertension, diabetes, or a family genetic kidney disease can speed decline under the extra load —
the reason for strict pre-donation screening and yearly blood pressure and urine albumin checks.

Frequently asked questions (FAQ)

Is a kidney transplant really better than long-term dialysis?

For people who are fit for surgery, yes. A US registry study of 228,552 dialysis patients found that transplant recipients had 48–82% lower long-term mortality than patients who stayed on dialysis while waitlisted, even though risk is temporarily higher in the first 2 weeks after surgery. A review of 110 studies also found clearly better quality of life and fewer cardiovascular events. The trade-off is lifelong immunosuppression, and not everyone is a surgical candidate.

Will a transplanted kidney work at 100%?

No. One transplanted kidney typically gives an eGFR of about 45–70 mL/min/1.73 m², equivalent to transplant CKD stage 2–3 (CKD 2–3T). That is still many times more than dialysis, which replaces only roughly 10–15% of normal kidney clearance when averaged over a week. A graft also works 24 hours a day, filtering waste, balancing water and minerals, and making hormones that support red blood cells and bone.

Will an enlarged heart (LVH) from dialysis go away after transplant?

It can improve partly, but not reliably. About 74% of people starting kidney replacement therapy already have left ventricular hypertrophy. After transplant, one study found left ventricular mass index fell from 161 to 146 g/m² between years 1 and 2 and then plateaued, while a cardiac MRI study found no significant change. Blood pressure, anemia, weight, and lipids still need control, because cardiovascular disease remains a leading cause of death with a functioning graft.

How dangerous is it to donate a kidney to a family member?

The risk is low but not zero. Among 80,347 US donors, surgical mortality was about 3.1 per 10,000, and long-term survival was similar to matched healthy people. The 15-year risk of end-stage kidney disease was about 30.8 per 10,000 donors, higher than matched healthy non-donors (3.9 per 10,000), but the estimated lifetime risk for donors (about 90 per 10,000) is still lower than the unscreened general population (about 326 per 10,000).

How should a donor look after themselves with one kidney?

The remaining kidney compensates, and filtration usually recovers to about 60–70% of the pre-donation level. Donors should check blood pressure, creatinine or eGFR, and urine albumin at least once a year for life, keep a healthy weight, avoid smoking, avoid regular NSAID painkillers without medical advice, and tell every doctor they have one kidney. In a follow-up averaging 12.2 years, 85.5% of donors still had a GFR of 60 or higher.

Can a woman still get pregnant after donating a kidney?

Yes, and most pregnancies are uncomplicated. A Canadian study found gestational hypertension or preeclampsia in 11% of donor pregnancies versus 5% in non-donors, while rates of preterm birth and low birth weight were not significantly different. Women who may want children should discuss this before donating, and once pregnant should tell their obstetrician they are a kidney donor so blood pressure and urine protein can be monitored.

I feel guilty about accepting a kidney from my child or sibling. What can help?

Guilt is common among recipients. It helps when the transplant team evaluates the donor separately from the recipient, when an independent living donor advocate or psychologist is involved (if the centre has one), and when everyone knows the donor can withdraw at any time without the team disclosing why. Conversations should stress that the decision belongs to the donor, while the recipient’s role is to protect the graft: take immunosuppressants on time and keep every appointment. If guilt disrupts sleep or energy for more than 2 weeks, ask to see a psychologist or psychiatrist.

What medicines are needed after a kidney transplant, and for how long?

Immunosuppressants are taken every day for as long as the graft works. A common regimen is a calcineurin inhibitor such as tacrolimus plus mycophenolate and corticosteroids, with doses adjusted to blood levels. In the first months, most recipients also take preventive medicines against infections such as PJP pneumonia and CMV. Never stop or reduce doses yourself, and tell the transplant team before starting any new medicine, herbal product, or supplement, because many change immunosuppressant levels.

In Thailand, who can be a living kidney donor, and is transplant covered?

Under Medical Council of Thailand criteria, a living donor must be a blood relative or a legally married spouse of at least 3 years (or less if the couple has a child together), and organ trading is prohibited; confirm current details with the hospital. People without a living donor can register for a deceased-donor kidney through the Thai Red Cross Organ Donation Centre. The main schemes (Universal Coverage, Social Security, and civil servant benefits) include kidney transplant and immunosuppressants, but conditions can change, so check with the hospital or the NHSO hotline 1330.
