  • Kidney transplants and dialysis both have pros and cons.
  • Exam expectations include evaluating these pros and cons.
  • Dialysis involves long, frequent sessions, typically 4 hours, three times a week.
  • Dialysis limits freedom as travel must be planned around treatment availability.
  • Dialysis requires a restricted diet, avoiding high protein and salt to prevent toxic waste buildup.
  • Dialysis patients must limit fluid intake to avoid swelling and discomfort.
  • Anti-clotting drugs are necessary during dialysis to prevent blood clots, which can lead to excessive bleeding.
  • Dialysis is more expensive than a kidney transplant due to ongoing sessions.
  • Dialysis can cause low blood pressure, leading to dizziness, fatigue, and nausea.
  • Kidney transplant is a major surgery with general risks and potential complications.
  • Long waiting lists for kidney transplants, often several years, during which dialysis continues.
  • Risk of transplant rejection by the immune system, requiring immunosuppressant drugs that increase infection risks.
  • Despite disadvantages, kidney transplants are generally better as they offer a permanent solution and are cost-effective over time.
