Abstract

Objectives: To describe the morphological and vascular characteristics of kidneys in living donors using 256-slice computed tomography (CT) imaging. Methods: A retrospective, descriptive study was conducted on 171 living kidney donors at VietDuc University Hospital from January 2024 to December 2024. Results: The mean age was 38.48 ± 9.30 years (range: 24 - 63), including 81 males and 90 females. Average kidney dimensions (length × width × thickness) were: Right kidney (100.61 ± 6.91mm) × (56.52 ± 5.80mm) × (41.33 ± 4.63mm); left kidney (103.11 ± 7.15mm) × (56.54 ± 5.95mm) × (44.17 ± 5.00mm). The right renal artery was significantly longer than the left (36.27 ± 12.77mm vs. 28.38 ± 10.67mm; p < 0.05), whereas the left renal vein was longer than the right (65.21 ± 14.57mm vs. 27.19 ± 8.89mm; p < 0.05). Most kidneys had a single renal artery and vein; however, 20.7% had two or more arteries, and 8.8% had multiple veins. The mean diameters of the right and left renal arteries were 5.25 ± 1.16mm and 5.73 ± 2.57mm, respectively (p > 0.05). The mean diameters of the right and left renal veins were 12.61 ± 3.08mm and 11.52 ± 4.16 mm, respectively (p > 0.05). Conclusion: No statistically significant differences were observed in mean renal dimensions between males and females, or between the right and left kidneys (p > 0.05). Most kidneys had a single renal artery and a single renal vein. The right renal artery was longer than the left, whereas the left renal vein was longer than the right (p < 0.05).
