2. ADVANTAGES OF
TRANSPLANTATION
Better quality of life - freedom from dialysis.
Avoid long-term complications of dialysis.
Higher energy levels.
Less dietary and fluid restrictions.
PATIENTS SURVIVAL:
• Chronic dialysis :
-mortality rate of 6-20% per year and as high as 11-25%. per year in diabetic
patients.
• Renal transplantation:
-Operative mortality rate of less than 2%.
-The 1-year survival for recipients of living related kidneys is better than 95%.
-The 5-year patient survivals are approximately 80% for nondiabetic recipients
and 60-70% for diabetic recipients.
3. In 1954, the first successful kidney
transplantation was performed using a
kidney from a living donor: the identical twin
of the recipient.

11. Most transplant centers exclude donors with proteinuria that exceeds 300 mg/day, while others use a lower threshold of greater
than 150 mg/day.
Some centers exclude everyone with >10 RBC/hpf as a possible transplant donor. Others will only accept a donor with
hematuria if the urologic evaluation and kidney biopsy are negative.
Any donor with persistent hematuria should have a thorough urological evaluation and kidney biopsy.
EXCLUSION CRITERIA FOR DONATION
Most centers require that donors have a glomerular filtration rate (GFR) of at least 80 mL/min.
If renal function is evaluated via a creatinine clearance, the adequacy of the 24 hour urine collection should be carefully
assessed.
Dietary intake of protein should be at least 1 g of protein /kg/body weight, since a low protein diet may decrease creatinine
clearance by as much as 10 mL/min.
-The MDRD equation also has to be used with caution.
-The CKD-EPI equation may estimate GFR more accurately than the MDRD equation among those with a true
GFR greater than 60 mL/min.
-However, estimation equations are frequently inaccurate when used for potential kidney donors.
Difficulties inherent to the accurate measurement of the creatinine clearance, including variability in urine collections, may affect
results.
Some centers therefore advocate the use of eGFR calculations such as the MDRD equation for the initial screen.
Among those with a GFR < 80 mL/min by initial estimation, isotopic studies are subsequently performed to measure renal
function more accurately.
13. The Amsterdam Forum on the Care of the Living Kidney Donor (2006)
individuals with a history of diabetes or fasting blood glucose ≥7 mmol/L on
at least two occasions (or 2 h glucose with OGTT ≥11.1 mmol/L should not
donate.
The Canadian Council for Donation and Transplantation(2006)
We recommend . . . to refer to existing guidelines regarding the assessment
and eligibility of potential living kidney donors (e.g. Amsterdam Forum).
European Renal Association-EDTA (2000) . . . exclusion criteria: . . . DM
UK Guidelines for Living Donor Kidney Transplantation (2005)
Diabetes mellitus is an absolute contraindication to living donation. Prospective
donors with an increased risk of type 2 diabetes mellitus because of family
history, ethnicity or obesity should undergo a glucose tolerance test and only be
considered further as donors if this is normal.
INTERNATIONAL GUIDELINES
17. Psychological assessment
• Relationship to the recipient
• Motivation to donate
• Knowledge about donor surgery and risks of surgery
• Capacity to make decisions
• Knowledge about recipient surgery and alternatives to living donation.
• Psychiatric symptoms.
• Alcohol or substance abuse or dependence.
• Financial stressors and economic impact of surgery.
• Family support.
• Awareness of ability to decline to proceed with surgery.
18. Elements of securing informed consent
• Ensuring the participant’s understanding of the procedure
& sequelae.
• Confirming the participant’s medical & psychological
suitability.
• Educating the donor.
• Ensuring the absence of coercion and free choice.
• Documenting informed consent.
20. EXCLUSION CRITERIA FOR DONATION

• Pregnancy or breast feeding.
• Positive serology for HCV, HBV, or HIV.
• Significant liver disease.

• Active systemic or localized major infection.
• Evidence of lung infiltrates, cavitation(s)or consolidation.
• Subjects with a screening baseline hemoglobin < 11gm/dl.
• Total white blood cell count ≤ 2,000/ mm3 .
• Platelet count ≤ 100000/ mm3 .
• Fasting triglycerides ≥ 400mg/dl or
• Fasting total cholesterol ≥ 300mg/dl.
21. History of nephrolithiasis.
