Abstract:Objective To explore the clinical value of Three-Dimensional (3D) printing for renal
duplication, this present study constructed a 3D printing model based on the multiphase enhanced
CT of the abdominal image. Methods One patient with 8 months of right kidney and ureter double
malformations was performed 64-slice contrast-enhanced CT reconstruction with iterative algorithm; through
importing the DICOM CT data into mimics 17.0 software, the images in arterial phase of the renal artery,
vein of kidney images, the delay phase of vesicoureteral image were extracted respectively. Images were
segmented depending on the different values of CT and the region of interest was reconstructed to generate
stereolithography file data. Then the modeling process was completed after importing the data into OBJET 260
3D printer. Results The 3D model was constructed by fusing different phase images in the same model, the
anatomical structure of artery, kidney, ureter and bladder were observed. It was of significant importance in
the resection of renal duplication and ureter lesion. Conclusion The model based on multi phase CT 3D
printing is a very important method to assist the diagnosis and treatment of repeated renal malformations.
