Pre-kidney transplant evaluation from a cadaver
When is this exam indicated?
The assignment of organs is mainly based on the characteristics of the blood group (A,B,O) and the major histocompatibility system (HLA). The waiting time on the list is not predictable and depends only on the availability of compatible organs.
How is it performed?
The transplant recipient is summoned to the hospital when the transplant kidney becomes available. Once at the hospital, the recipient performs the final pre-operative tests (blood tests, chest x-ray and electrocardiogram) and is directed to the operating room.
The assessment of the suitability of the donor´s organs and tissues is aimed at minimizing the risk of transmission of diseases from donor to recipient following transplantation, infectious or neoplastic. On the basis of risk characteristics donors are classified:
A - STANDARD DONOR
This risk class includes all donors with no risk factors for transmissible diseases emerging from the evaluation process.
B - ELIGIBLE NON STANDARD DONOR
- with negligible risk
This level of non-standard risk includes cases in which risk factors are detected in the donor but these factors do not imply any restriction in the selection of recipients because they are not such as to determine the onset of disease or an increased risk of failure of the transplant and/or mortality of the recipient.
- with acceptable risk
This includes cases in which the use of the organs of these donors is justified by the fact that it does not lead to any change in the success rate of the transplant and/or the survival of the patient.
- unacceptable risk
Donor organs cannot be used due to the presence of pathogens or transmissible diseases that pose a risk to recipients.
