Obesity : Candidates must have a body mass index listing for transplantation state that candidates must (BMI, weight/body surface area) of <38. Recipient Factors either be on dialysis or have near loss of kidney 10. Functional status : Candidates must be able to function with a creatinine clearance < 20cc/min walk short distances and perform activities of daily living (normal is >80). without assistance. 2. Adequate urinary tract : POSITIVE OUTCOMES NEGATIVE OUTCOMES 11. Psychosocial status : Candidates must be 3. Acceptable cardiovascular function : motivated, have demonstrated compliance with medical Contraindications to transplantation include and dialysis regimens, not suffer from psychosis, live in Older age Younger age significant un-correctible coronary artery disease a stable environment, capable of supporting compliance and/or poor cardiac pump function. with the transplant regimen including transportation, Greater HLA match with recipient HLA mismatched with recipient and not be an active substance abuser, (+/- cannabis) 4. Acceptable vascular system : 12. Financial considerations : 5. Acceptable lung function : Smokers may be Ideal BMI or non-diabetic Under or 0verweight or diabetes declined until they are able to quit (based on age and medical history). Good fitness Poor fitness 6. Acceptable liver function : 7. Active significant fungal or bacterial infection is Less sensitized Highly sensitized a contraindication to transplantation. 8. Cancer screening : Appropriate for age tests will Disease with lower risk of recurrence Disease with higher risk of recurrence be necessary including colonoscopy (age>50yo), prostatic specific antigen, etc. Transplant Phase • Starts with donor offer – local donor vs import • Transplant center reviews the HLA match run and calls their potential recipients – each kidney has a primary candidate and backup candidate • Either admit potential recipient or have them provide blood for a final crossmatch • Medical suitability and final clearance • Dialysis coordination if necessary • Schedule surgery – time of day, cold ischemic time, surgeon “freshness” 6

6/11/2018 Post-Transplant Phase • Conduct frequent lab tests and office visits • Review side effects of medication • Evaluate surgical healing and remove staples, tubes, and stent • Balance immune suppression medication • Screen for infection • Address psychological concerns This Photo by Unknown Author is licensed under CC BY-NC QUESTIONS? 7
