Abstract
Purpose: To assess the value of MDCT in evaluation of the anatomy of living kidney donors and in revealing the prevalence of renal vascular variations.
 Materials and Methods: This retrospective study was approved by the Ethics committee of Rajavithi hospital(NO.172/2555). The accuracy of the images of vessel structures obtained by using 64-row multidetector computed tomography (MDCT) angiography in comparison with the actual vessel structures observed during surgery was analyzed retrospectively. We analyzed 20 patients who had undergone donor nephrectomy from 2008 to 2012. Preoperative MDCT angiography was performed, and the surgeons themselves subsequently recorded the operative findings.
 Results: Nephrectomy was performed on the left side in all 20 patients. The accuracy levels of MDCT for the artery and the vein were 90% and 95% respectively.
 Conclusions: MDCT angiography is a good investigative technique for the preoperative evaluation of the anatomy of vessels.
