Abstract:

BACKGROUND: Preoperative imaging for evaluation of donor renal vessels is necessary to select a suitable donor and to plan an operative method.
OBJECTIVE: To evaluate the sensitivity of 16-section CT angiography (CTA) as the primary imaging technique in preoperative living kidney donors.
METHODS: A total of 59 cases had been evaluated preoperatively by 16-section CTA with 3-D reconstruction. Arterial anatomy described by skilled radiologists was compared with intraoperative findings. The sensitivity and accuracy of CTA examination of the renal vascular were analyzed.
RESULTS AND CONCLUSION: Totally, the sensitivity and accuracy of CTA in renal artery were 96.6% and 90.5%, respectively. Fifty donors were found to have single kidney artery during operation. For these donors, the diagnostic sensitivity and accuracy of CTA were 96.1% and 92.9%, respectively. In 6 donors with two renal arteries, the sensitivity and accuracy of CTA both decreased to 83.3%. In 3 donors with three renal arteries, the sensitivity and accuracy of CTA were both 66.7%. The total diagnostic accuracy of 16-section CTA for multi-vessel renal artery was 77.7%. The noninvasive and three dimensional visual 16-section CTA examination can accurately and clearly predict arterial vasculature in more than 90.5% of donors. It is also a better means for preoperative vascular assessment.
