Describe the criteria that is utilized for patients to be placed on the waitlist.
Identify the factors involved for transplant candidate evaluation. What are the considerations for living donors?
Kidney Disease Outcome Quality
Initiative ( K/DOQI) Staging
K/DOQI created the standardization of clinical practice guidelines.
Two primary markers are used to stage Chronic
Kidney Disease (CKD).
Abnormalities in serum and urine lab tests:
BUN, Creatinine
Level of Kidney function as measured by
Glomerular Filtration Rate (GFR).
Stages of Kidney Failure- K/DOQI Staging:
Stage Description
1 Kidney damage with normal or
increased GFR
2 Kidney damage with mild decrease in GFR
3 Moderate decrease in GFR
4 Severe decrease in GFR
5 Kidney failure
GFR (ml/min)
Equal to, or > 90
60-90
30-59
15-29
Less than 15
A patient must be in stage 4 or 5 End
Stage Renal Disease (ESRD)
Renal failure must be chronic and irreversible
GFR must be <20 to accrue wait time
A live renal transplant may be completed prior to the initiation of dialysis and GFR does not need to be <20.
The goal of kidney pancreas transplant is to cease the need for insulin dosage and to ease the suffering of sequelae of diabetes such as:
Gastroparesis
Renal Failure
Retinopathy
Neuropathy
Accelerated Cardiovascular disease
Improves quality of life
Patients receive a kidney/pancreas transplant as Type 1 diabetes has caused irreversible damage to both pancreas and kidney
Physiologically the potential candidate needs to be able to withstand the transplant procedure itself and have a lower risk of long term morbidity and mortality.
If the potential candidate is able to resolve contraindications found at initial assessment, then they may be re-assessed.
Older age, in itself, is not a contraindication.

Pre-Transplant Waitlist & Evaluation Process
•
•
•
•
•
•
Potential recipient meets with Multi–Disciplinary Team
Potential recipient receives education regarding the risks and benefits of transplant, medical and financial acceptability, tests that will be required, and the organ allocation process.
Potential recipient completes work up and lab tests.
All candidates added to the transplant waitlist must be approved through the Patient Selection Committee.
Testing for any potential living donor will be done after the patient waiting for an organ is placed on the active transplant waitlist.
When a patient is on the active waitlist, he/she must follow up with transplant team bi-annually until the transplant has occurred.
Absolute Contraindications To Transplantation
Severe, untreatable heart or lung disease
Active or uncontrollable cancer
Current alcohol abuse or drug addiction
Uncontrollable infection
Uncontrollable HIV infection
Failure of other organs that will not improve with transplant.
Limited life expectancy
History of non-compliance medical/dietary recommendations pre-transplant
Education is imperative to enable the potential living donor to understand all aspects of the donation process, especially the risks and benefits. The goal of informed consent is to ensure that a potential donor understands:
That he or she will undertake risk and will receive no financial benefit from the donor nephrectomy
That he or she may be at risk for psycho/social issues: depression or anxiety related to complication from surgery, feelings of burden, body image, family tensions, loss of employment and related financial or emotional concern.
That there are general risks of the operation.

Psychosocial evaluation
Transplant procedure
The patient is anesthetized and a central venous catheter and urinary catheter are placed.
The bladder is decontaminated with antibiotic solution
The usual placement of the kidney is extraperitoneal in the iliac fossa.
Pancreas will also be placed extraperitoneally
Vascular anastamosis will be to iliac artery and vein. The kidney should turn pink and produce urine immediately.
Pancreas head will either be anastomosed to small bowel (enteric drained)or to bladder (bladder drained)
Approximated 2 liters of pancreatic fluid will be reabsorbed if enteric drained. If bladder drained, these pancreatic fluids will be excreted and may cause fluid depletion.
The donor ureter is anastomosed to the recipient bladder and a double J stent is placed. This stent facilitates healing across the anastamosis and will be removed in the transplant clinic in 4-6 weeks via cystoscopy
After organ(s) are placed a final check for hemostasis and the positioning of the vessels is done and a standard wound closure is done.
All patients who receive a transplant are placed on a medication regime that suppresses the bodies’ natural immune response to protect the integrity of the graft.
There are many possible combinations of medication regimes, depending on the center’s protocol.
Induction Therapy
Initial potent prophylactic immunosuppression at the time of transplant to prevent hyper-acute or acute rejection
Agent of choice is dependent on recipients pre-existing medical conditions, donor characteristics, and the maintenance immunosuppressive regimen to be used
Lymphocyte count will drastically decrease.
Anti-fungal, anti-viral and anti-bacterial prophylaxis is required
Effect may last for months
Maintenance Immunosuppression
Medications will be taken for the life of the allograft
Patient compliance is critical to graft survival
Goal is to prevent rejection
Enteric Drainage (Panreaticojejunostomy)
Anastamosis of pancreas to Jejunum via a
Roux-en-Y loop
Mimics normal enteric drainage of pancreatic enzymes
Difficult to diagnose rejection, can't measure secretion of enzymes
Urinary Diversion
(Pancreaticoduodencystostomy)
Pancreas anastomosed to the recipients bladder
Offers a direct method for assessing graft exocrine function (urine amylase decreases earlier than changes in blood glucose if graft is rejecting)
Complications:
Metabolic acidosis from bicarbonate loss into urine
Ulceration/bleeding at duodenal segment
Cystitis
Volume imbalance due to excretion of ~ 2000 ml pancreatic fluid daily.
