CTP Donor & Recipient Evaluation 4

Question 1

Which scoring system is used to assess the quality and predicted graft function of a deceased donor kidney before transplantation?

Accepted Answer

KDRI (Kidney Donor Risk Index)

Answer

The KDRI estimates the relative risk of kidney graft failure based on donor characteristics such as age, creatinine, hypertension, and cause of death.

Question 2

In donation after circulatory death (DCD), which organ is considered MOST vulnerable to warm ischemia during the withdrawal of life support phase?

Accepted Answer

Liver

Answer

The liver is most sensitive to warm ischemia in DCD donors and has the highest risk of primary non-function and ischemic cholangiopathy.

Question 3

Which donor condition is classified as a 'Public Health Service (PHS) Increased Risk' behavior that must be disclosed to potential recipients?

Accepted Answer

Incarceration in the past 12 months

Answer

PHS Increased Risk criteria include recent incarceration (within 12 months) because of higher prevalence of blood-borne infections in this population.

Question 4

A recipient has a calculated PRA of 85%. What does this indicate about their transplant candidacy?

Accepted Answer

They are highly sensitized and will likely need a virtual or prospective crossmatch

Answer

A PRA of 85% indicates high sensitization, meaning the recipient has antibodies against 85% of the population, requiring careful crossmatch strategy.

Question 5

Which factor is part of the standard evaluation for assessing a living kidney donor's long-term renal reserve?

Accepted Answer

24-hour urine creatinine clearance or GFR measurement

Answer

Measured GFR or 24-hour urine creatinine clearance is essential to confirm adequate bilateral renal function before nephrectomy in living donors.
