Summary
This study found no significant difference in kidney transplant outcomes between left and right deceased donor kidneys. Graft survival and function were comparable, indicating donor kidney side is not predictive of transplant success.
Area of Science:
- Nephrology
- Transplant Surgery
- Organ Donation
Background:
- Assessing the impact of donor kidney laterality on transplant outcomes is crucial for optimizing organ allocation.
- Previous research has not definitively established whether left or right deceased donor kidneys yield different results.
Purpose of the Study:
- To investigate if the side of the deceased donor kidney (left vs. right) influences kidney transplant outcomes.
- To compare graft function, complications, and survival rates between recipients of left and right donor kidneys.
Main Methods:
- Retrospective analysis of 201 left-right deceased donor kidney pairs transplanted between 1994 and 2004 in Queensland.
- Comparison of recipient baseline characteristics, operative details, post-operative complications, and graft survival rates.
Main Results:
- No significant differences were observed in operative duration, warm or cold ischemic times, or delayed graft function.
- Estimated glomerular filtration rates at 1 month and beyond were comparable between left and right kidney recipients.
- Death-censored graft survival rates at 1, 3, and 5 years were similar for both groups, with no statistically significant differences.
Conclusions:
- Despite potential differences in operative challenges, donor kidney side does not appear to predict early post-operative complications.
- The side of the deceased donor kidney does not impact early or medium-term renal allograft function.
- Left and right deceased donor kidneys demonstrate comparable rates of death-censored graft failure, suggesting side is not a critical factor in long-term transplant success.
