Transplanting a left or right donor kidney into the left or right iliac fossa: importance of laterality and site of venous anastomosis.

Data on the impact of donor-to-recipient laterality on kidney transplantation are lacking. This study evaluated the impact of donor-to-iliac fossa laterality and the site of venous anastomosis on operating time and surgical outcome. This retrospective single-center study analyzed 1262 deceased donor adult kidney transplants into pristine iliac fossa. Multivariable linear and logistic regression analyses were used to identify variables with an impact on operating time and surgical complications. Operating time was shorter by 11 min in median for transplantations into the right iliac fossa compared to the left iliac fossa (p < 0.001). Operating time in left-to-right donor-to-recipient combination was shorter by 17 min in median if venous anastomoses were performed on the caval vein or common iliac vein as compared to anastomoses to the external iliac vein (p < 0.001). Overall, the shortest operating times (median 112.5 min) were achieved in left-to-right donor-to-recipient combinations with venous anastomosis to the caval or common iliac vein, without an increase in surgical complications. Kidney transplantation into the right iliac fossa with anastomosis to the caval vein or the common iliac vein saves operating time and reduces thrombotic complications. Acceptance of a left donor kidney is likely to further reduce operating time.

Evaluation of living liver donors using contrast enhanced multidetector CT - The radiologists impact on donor selection.

BACKGROUND: Living donor liver transplantation (LDLT) is a valuable and legitimate treatment for patients with end-stage liver disease. Computed tomography (CT) has proven to be an important tool in the process of donor evaluation. The purpose of this study was to evaluate the significance of CT in the donor selection process. METHODS: Between May 1999 and October 2010 170 candidate donors underwent biphasic CT. We retrospectively reviewed the results of the CT and liver volumetry, and assessed reasons for rejection. RESULTS: 89 candidates underwent partial liver resection (52.4%). Based on the results of liver CT and volumetry 22 candidates were excluded as donors (31% of the cases). Reasons included fatty liver (n = 9), vascular anatomical variants (n = 4), incidental finding of hemangioma and focal nodular hyperplasia (n = 1) and small (n = 5) or large for size (n = 5) graft volume. CONCLUSION: CT based imaging of the liver in combination with dedicated software plays a key role in the process of evaluation of candidates for LDLT. It may account for up to 1/3 of the contraindications for LDLT.
