Abstract

Objective: The purpose of this study was to determinate the accuracy of multidetector computed tomography (MDCT) angiography for imaging evaluation of renal arterial and venous structures of living donor kidney
Materials and Methods: Two hundred twenty-eight potential living donor candidates were included to this study, who had CTA for the assessment of their renal vessels in our hospital between January 2018 and
June 2020 and one hundred-eighty donors who underwent open surgical in this time. The number, course, and drainage patterns of the renal vessel were retrospectively observed from the scans. Anomalies of renal arteries,
veins and inferior vena cava (IVC) were recorded. Multiplanar reformations
(MPRs), maximum intensity projections, and volume rendering were used for analysis. The results obtained were correlated surgically.
Results: A total of 228 potential live kidney donors underwent renal CTA (112 of the patients were male, and 116 were female. Mean age of donors was 38,32 ± 12,34 years. among them 180 patients had donor
nephrectomy. There were 151 kidneys had single renal artery , here were 29 kidneys had at least one accessory or polar artery. There were 45 early branching renal arteries, two kidneys were retroaortic left renal veins. 16
kidneys had multiple renal veins. 55 kidneys wewe late venous confluence of renal veins. Sn, Sp, NPV, PPV compare open oparative nephrectomy 87,5%- 100%.
Conclusion: Renal CTA is an accurate, safe and noninvasive diagnostic tool for determination of renal artery and vein abnormalities in living kidney donors preooparative. It helps with surgery planning,
choosing operation side and exclusion of donors.
