Overview
When an organ becomes too damaged to perform its essential functions, life-threatening organ failure can occur. Organ transplantation is a proven treatment in which a healthy organ from a donor is implanted into a recipient whose own organ no longer works adequately. While many medical therapies can slow disease, transplantation may be the only option that restores near-normal organ function and quality of life in end-stage organ failure.
At MedicalPoint Hospital, our multidisciplinary transplant team (transplant surgeons, hepatologists/nephrologists, anesthesiologists, infectious disease specialists, interventional radiologists, psychologists, dietitians, and transplant coordinators) delivers end-to-end care: evaluation, listing, surgery, intensive care, rehabilitation, and long-term follow-up.
Types of Organ Donation and Transplant
Transplantable organs and tissues may come from two sources:
1) Deceased (Cadaveric) Donation
Organs are recovered from donors who have confirmed brain death and have consented to donation (or whose next of kin authorize donation in line with local law and ethics). Organs are assessed for safety (infection screening, organ function, anatomy), preserved in special solutions, and allocated to suitable recipients on the national waiting list according to medical urgency, compatibility, and fairness.
Commonly transplanted from deceased donors: heart, lungs, liver, kidneys, pancreas, and intestines. Tissues may include corneas, skin, bone, tendons, and heart valves. (Highly specialized centers may perform vascularized composite allotransplantation such as hand or face transplantation in strictly selected cases.)
2) Living Donation
In carefully evaluated cases, a healthy relative or altruistic volunteer may donate a kidney (people can live well with one kidney) or a portion of the liver (the liver regenerates). Living donation requires rigorous medical and psychosocial assessment to protect the donor and recipient. At MedicalPoint, living donors receive dedicated counseling, minimally invasive techniques when possible, and structured long-term follow-up.
Kidney Transplantation: What to Expect
Kidneys filter toxins, regulate fluid/electrolyte balance, and maintain acid–base homeostasis. In chronic kidney disease (CKD) progressing to end-stage kidney failure, dialysis can replace some functions but is time-consuming and may not provide the same well-being as transplantation.
Evaluation and Listing
- Comprehensive assessment of recipient (cardiac risk, infections, malignancy screening, immunologic profiling)
- Donor evaluation (for living donors): blood tests, imaging, kidney function, crossmatch, psychosocial review
- Immunologic compatibility: ABO blood group and HLA typing/crossmatch are used to reduce rejection risk. (Note: donors do not always need the same blood type; they must be ABO-compatible—for example, O can donate to O, A, B, or AB in kidney programs with appropriate protocols. In select centers, ABO-incompatible transplants may be performed with specialized desensitization.)
The Operation
- The donor kidney is placed in the recipient’s lower abdomen and connected to the iliac vessels; the ureter is joined to the bladder.
- Native kidneys typically remain in place unless medically indicated.
- Living-donor kidneys often begin producing urine immediately; deceased-donor kidneys may have delayed graft function and require temporary dialysis.
Aftercare
- Immunosuppressive therapy (e.g., tacrolimus/cyclosporine, mycophenolate, steroids) prevents rejection.
- Close monitoring for infection, rejection (acute/chronic), cardiovascular risks, diabetes, and medication side effects.
- Lifestyle optimization (nutrition, exercise, vaccination, smoking cessation) is essential.
Liver Transplantation: Key Points
The liver performs hundreds of vital tasks: detoxification, metabolism, bile production, and protein synthesis. Liver transplantation is indicated for irreversible liver failure (e.g., cirrhosis, acute liver failure), selected liver cancers (e.g., hepatocellular carcinoma within criteria), and metabolic diseases.
Living-Donor Liver Transplant
- A size-matched portion (e.g., left lateral segment for children; right or left lobe for adults) is donated.
- Donor safety is paramount: volumetric imaging and functional testing ensure adequate future liver remnant.
- Both donor and recipient livers regenerate substantially over weeks to months.
Post-Transplant Considerations
- Rejection and biliary/vascular complications are monitored with labs and imaging.
- Lifelong immunosuppression and infection prophylaxis are required.
- Nutrition, alcohol abstinence, and management of comorbidities support graft longevity.
How Organ Transplants Are Performed at MedicalPoint
1) Referral & Multidisciplinary Evaluation
Patients with organ failure are referred to MedicalPoint’s Transplant Coordination Center. We assess:
- Disease severity and timing for transplant
- Compatibility (ABO, HLA for kidney; size matching and vascular anatomy for liver)
- Infection and cancer screening
- Cardiopulmonary fitness and nutrition
- Psychosocial readiness, support systems, and adherence potential
2) Placement on the Waiting List
In Türkiye, eligible patients are listed on the national waiting list coordinated by the Ministry of Health. Allocation follows medical urgency, waiting time, and compatibility criteria—never race, gender, language, religion, or wealth. While waiting, patients continue optimal medical therapy, dialysis (if needed), vaccination updates, and lifestyle measures.
3) The Surgery & ICU Care
- When an organ offer arrives, crossmatch/quality checks are confirmed.
- Expert surgical teams perform the transplant in advanced operating theaters with real-time imaging and anesthetic monitoring.
- Post-op, patients recover in the Transplant ICU with meticulous fluid, hemodynamic, pain, and infection control.
4) Long-Term Follow-Up
- Structured visits, blood tests (drug levels, kidney/liver function), imaging, and medication adjustments
- Education on warning signs (fever, reduced urine, jaundice, swelling, pain, elevated blood pressure), infection prevention, safe travel, and pregnancy planning when relevant
Compatibility and Blood Groups: What Really Matters
- ABO compatibility is preferred (e.g., O→any, A→A/AB, B→B/AB, AB→AB for kidneys; liver programs have center-specific rules).
- Rh factor (positive/negative) does not influence solid-organ matching.
- HLA matching and a negative crossmatch lower rejection risk (especially in kidney transplantation).
ABO-incompatible transplants may be possible in specialized programs using desensitization (plasmapheresis, immunomodulation)—indications and availability vary.
Risks, Rejection, and Safety
All transplants carry risks, which we minimize through rigorous protocols:
- Surgical risks: bleeding, thrombosis, leak (biliary/urinary), wound complications
- Immunologic risks:
- Hyperacute/acute rejection—managed with immunosuppression and targeted therapies
- Chronic rejection—gradual graft dysfunction requiring close surveillance
- Infections: opportunistic infections (CMV, BK virus, fungal); we use prophylaxis, vaccination, and early detection
- Medication effects: hypertension, diabetes, kidney toxicity (in liver recipients), bone thinning; these are managed proactively
- Recurrence of underlying disease in selected indications (center-specific protocols apply)
At MedicalPoint, shared decision-making ensures patients and families understand benefits, risks, and alternatives.
The Role of Organ Donation
Organ donation is voluntary. In Türkiye, adults with capacity can pledge to donate their organs after death; families are consulted with compassion and clarity after brain death is confirmed. Living donation follows strict medical, ethical, and legal safeguards to protect donors.
Why donation matters: One deceased donor can save or transform multiple lives by donating heart, lungs, liver, pancreas, kidneys, intestines and by providing tissues (corneas, skin, bone, valves). If you wish to become a donor, contact your local health authority or hospital for guidance on registration and consent.
Life After Transplant: Practical Guidance
- Medication adherence is non-negotiable. Never stop immunosuppressants without medical advice.
- Healthy lifestyle: smoke-free, balanced diet (dietitian-guided), safe physical activity, weight and blood-pressure control, adequate sleep.
- Infection prevention: hand hygiene, food safety, vaccinations (per transplant clinic schedules), and prompt reporting of fevers.
- Mental health & support: counseling and peer groups help with adjustment and long-term well-being.
- Regular follow-ups: keep all appointments; early detection of problems preserves graft function.

Organ Transplantation
Organ transplantation involves the replacement of a severely malfunctioning organ, which cannot be effectively treated through medical means, with a new organ sourced from either living donors or deceased donors diagnosed with brain death. This form of treatment is employed to address the patient’s condition. The Organ Transplantation Unit operates as a department that embraces a multidisciplinary treatment approach, involving transplantation surgeons, anesthesiologists, nephrologists, and gastroenterologists.
