　　Objective: To explore the three-dimensional visual modeling method of kidney vessels in miniature pigs and its application significance

　　Methods: One pair of fresh normal isolated mini pig kidneys were selected, and the abdominal aorta (red) and vena cava (yellow, right renal vein ligated) were perfused with "epoxy resin lead oxide" filling agent and the right renal vein was ligated with "epoxy resin titanium dioxide" filling agent respectively, and the casting was made. Then 128 slice spiral CT thin layer scanning was performed to collect two-dimensional image data sets, and Mimics19.0 software was used to segment the vascular threshold and reconstruct the three-dimensional visual model of mini pig renal vessels

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

　　Conclusion: The three-dimensional visualization model of miniature pig kidney blood vessels effectively segmented based on the reconstruction of vascular cast specimens lays the foundation of simulation platform and provides important guiding significance for the research of urology and virtual training of surgery
