Objectives:
Kidneys classified to be so-called tumor-bearing kidneys as potential donor kidneys typically involve small (<4 cm), low-grade renal tumors resected ex vivo. Kidney transplant remains the definitive treatment for end-stage renal disease, yet organ shortages persist worldwide. The use of kidneys with small, resectable renal tumors has been proposed as a strategy to expand the donor pool.
Materials And Methods:
A national online survey was conducted from November to December 2019, targeting urologists, nephrologists, and transplant surgeons based in the United Kingdom. The aim was to assess clinician perspectives on the use of tumor-bearing kidneys as potential donor kidneys in selected patients with end-stage renal disease.
Results:
Of 230 clinicians approached, 108 responded (47%). Support for the use of tumor-bearing kidneys as potential donor kidneys was highest among transplant surgeons (100%), followed by urologists (71%) and nephrologists (54%).
Conclusions:
The findings demonstrate broad support among United Kingdom clinicians for the selective use of tumor-bearing kidneys as potential donor kidneys. Despite ethical and logistical concerns, this consensus may justify the initiation of formal trials and the development of centralized protocols to increase organ availability.
Insights
Clinicians in the UK support using tumor-bearing kidneys for transplantation to address organ shortages. This consensus suggests further trials are warranted to expand the donor pool for end-stage renal disease patients.
Area of Science:
- Nephrology and Urology
- Transplant Surgery
Background:
- Kidney transplantation is crucial for end-stage renal disease, but organ scarcity is a global issue.
- Utilizing kidneys with small, low-grade renal tumors (tumor-bearing kidneys) is a proposed strategy to increase donor organ availability.
- Ex vivo resection of small renal tumors from donor kidneys is a key consideration.
Purpose of the Study:
- To evaluate the perspectives of UK clinicians on using tumor-bearing kidneys for transplantation.
- To gauge support among urologists, nephrologists, and transplant surgeons for this organ donation strategy.
Main Methods:
- A national online survey was distributed to UK-based urologists, nephrologists, and transplant surgeons.
- The survey was conducted between November and December 2019.
- Response rate was 47% (108 out of 230 clinicians).
Main Results:
- A significant proportion of clinicians expressed support for using tumor-bearing kidneys.
- Support was highest among transplant surgeons (100%), followed by urologists (71%) and nephrologists (54%).
Conclusions:
- Broad support exists among UK clinicians for the selective use of tumor-bearing kidneys in transplantation.
- Despite ethical and logistical challenges, this consensus supports initiating formal trials.
- Development of centralized protocols is recommended to enhance organ availability for kidney transplants.
