Figure 3

Ultrasonographic and contrast CT images. Upper row: Ultrasound images on the first day after the operation are shown. Renal blood flow in H-DCD20 individuals is clearly confirmed; however, some areas are difficult to see with a Doppler. Almost no renal blood flow is observed in NH-DCD20 individuals, and the renal parenchyma shows a hypoechoic image similar to that of surrounding tissues. Kidney blood flow in DCD0 is clearly confirmed, and branching of interlobar arteries and veins is observed from segmental arteries and veins. Middle/lower row: contrast-enhanced CT is used to demonstrate the vascular and excretory phases, and 3D stereoscopic images are shown. In H-DCD20 and DCD0, inflow of contrast medium into the kidney is observed, and the ureter and bladder are imaged. However, in individuals of NH-DCD20 and H-DCD20 without blood flow, the renal arteries are not imaged, and the ureter and bladder are not imaged during the excretory phase (yellow circle, transplanted kidney). CT, computed tomography; 3D, three-dimensional. *H-DCD20, n = 4; NH-DCD20, n = 3; DCD0, n = 1.
