Abstract

Objective: To explore the characteristics of the transplanted kidneys’ morphology, blood flow perfusion when rejection occurred by 2D and 3D ultrasound. The volume and the vascularization index(VI) were analyzed quantitatively. Methods: Thirty transplanted kidneys with rejection and thirty normal transplanted kidneys were examined by 2D and 3D ultrasound. 3D ultrasound imaging was reconstructed off-line. The length, width and height were measured on 2D imaging. The volume and VI were calculated by 3D imaging. Results: The volume of transplanted kidneys in rejection group is significantly different from that of control group(P<0.05). It is more sensitive than the length, the width and the height. There is significant difference of VI between the rejection and the control group(P<0.05). Conclusion: When rejection occurred, the volume of the transplanted kidneys obtained by 3D is more sensitive than the size obtained by 2D. VI can describe the decrease of transplanted kidneys’ blood flow perfusion.
