　　OBJECTIVE: To explore the 3D visualization modeling method of kidney blood vessels in miniature pigs and its application significance.

　　Methods: A pair of fresh normal isolated minipig kidneys were selected, and the abdominal aorta (red) and the vena cava (yellow, ligated) were perfused with the "epoxy-lead oxide" filler respectively. Right renal vein) and casts were made, and then a 128-slice spiral CT thin-slice scan was performed to collect a two-dimensional image data set, and Mimics 19.0 software was used to perform threshold segmentation of blood vessels and reconstruct a three-dimensional visualization model of mini-pig kidney blood vessels.

　　Results: The three-dimensional visualization model of renal blood vessels in miniature pigs was successfully reconstructed using Mimics19.0 software. The distribution and course of renal arteries and veins in the model were consistent with those of cast specimens. The renal arteries and veins were displayed by threshold segmentation of blood vessels, or the kidneys were displayed alone. Arteries, the effect is ideal, and the three-dimensional sense is strong.

　　Conclusion: Based on the vascular cast specimens, the effective segmentation of the 3D visualization model of miniature pig kidney vessels can be reconstructed, which lays the foundation of the simulation platform and provides important guiding significance for urology research and surgical virtual training.
