Kidney Transplantation

Kidney transplantation is a surgical procedure that replaces a non-functioning kidney with a healthy donor kidney. It is considered the preferred treatment for end-stage renal disease (ESRD), offering better long-term survival and quality of life compared to maintenance dialysis.

Common causes of ESRD include:

• Diabetes mellitus
• Hypertension
• Glomerulonephritis
• Polycystic kidney disease
• Chronic interstitial nephritis
• Autoimmune diseases such as lupus

Healthy kidneys regulate fluid balance, electrolytes, acid-base status, and waste removal. When kidney function declines irreversibly, patients may require dialysis. Transplantation restores many of these physiological functions and can eliminate the need for long-term dialysis.

Comprehensive Evaluation

Candidates undergo a multidisciplinary assessment including nephrologists, transplant surgeons, cardiologists, and social support teams.

Evaluation typically includes:

• Blood typing and tissue compatibility testing (HLA typing)
• Crossmatch testing to assess antibody compatibility
• Cardiac evaluation (stress testing or echocardiography)
• Cancer screening
• Infection screening (hepatitis, HIV, tuberculosis)
• Vascular imaging if indicated

Donor Types

Kidneys may come from:

• Living donors (related or unrelated)
• Deceased donors
• Living donor transplantation is often associated with shorter waiting time and better long-term graft survival.

Waiting Period

Patients awaiting deceased donor transplantation are listed based on medical factors and compatibility. While waiting, patients typically continue dialysis and must remain in stable condition to proceed with surgery when an organ becomes available.

During Surgery

Kidney transplant surgery generally lasts 2 to 4 hours and is performed under general anesthesia.

Key surgical steps:

• The donor kidney is placed in the lower abdomen (iliac fossa).
• The renal artery and vein are connected to the recipient’s blood vessels.
• The ureter is attached to the bladder.

In most cases, the patient’s original kidneys are left in place unless there is a specific medical reason to remove them.

Immediate Postoperative Care

After surgery:

• Patients are monitored in a recovery unit or ICU.
• Urine output is closely monitored; many transplanted kidneys begin functioning immediately.
• Immunosuppressive medications are started to prevent rejection.
• Hospital stay typically lasts 5 to 10 days, depending on recovery and graft function.

Early Recovery

Frequent laboratory testing is required during the first few weeks to monitor:

• Kidney function (creatinine levels)
• Electrolytes
• Drug levels of immunosuppressive medications

Patients receive detailed education on medication adherence, infection prevention, and symptom monitoring.

Early Risks

• Delayed graft function (temporary need for dialysis after surgery)
• Acute rejection
• Bleeding or infection
• Vascular complications (renal artery or vein thrombosis)
• Urinary leakage or obstruction
  
  
  

Long-Term Risks

• Chronic rejection leading to gradual loss of graft function
• Cardiovascular disease
• Hypertension
• Diabetes related to immunosuppressive therapy
• Increased infection risk
• Elevated cancer risk due to long-term immunosuppression
  
  

Close follow-up significantly reduces the likelihood of severe complications.

Kidney transplantation significantly improves survival compared to long-term dialysis in most patients.

Long-term care includes:

• Lifelong immunosuppressive therapy
• Routine laboratory monitoring
• Blood pressure and metabolic control
• Cardiovascular risk management
• Regular cancer screening

With proper adherence and monitoring, many transplanted kidneys function for many years.
