Abstract: Objective    To explore the application value of 3D reconstruction technology of CT scanning and digital virtual surgery diagnosis and treatment system in adrenal tumors.    Methods    Data on 20 patients diagnosed with adrenal tumors and completed 3D reconstruction in The Second People′s Hospital of Guiyang from September 2016 to April 2023 were reviewed. A total of 19 cases were collected, including 12 cases of three-dimensional reconstruction adrenal tumors (3D group), 3 males and 9 females, with the mean age of (44.92±13.28) year. All the 12 patients in 3D group were three-dimensional reconstructed with enhanced CT image data before operation, and the reconstructed model was used to understand the tumor and its occupying position, as well as the relationship between the tumor and blood vessels and surrounding tissues and organs.  The operation plan, intraoperative guidance and doctor-patient communication was made according to the 3D reconstruction image. There were 7 cases without three-dimensional reconstruction (CT group), the mean age was (35.14±11.25) years. There were 3 males and 4 females in the CT group. The general information, surgical methods and perioperative data of the two groups were compared. The data were analyzed by using SPSS 26.0.    Results    Among the 19 cases, 18 cases were successfully completed. One case in the CT group was converted to open surgery due to insufficiently accurate preoperative evaluation, which resulted in the discovery of a huge tumor and complex anatomical relationship during the operation, and the inability to expose the complete tumor, central vein and renal vein. The operation time in the 3D group was shorter than that in the CT group, with a statistically significant difference (P<0.05). There were no significant differences in general information(age and gender), intraoperative bleeding volume, postoperative length of stay, and drainage tube removal time between the two groups (P>0.05).   Conclusions   3D visualization and realistic reconstruction technology is an important foundation for construction of virtual diagnosis and treatment of digital  urology. 3D reconstruction models can reduce anatomical disorientation in adrenal tumor surgery to achieve accurate intraoperative resection, thereby shortening the surgical time. It is beneficial to reduce surgical risk and has high clinical application value in urology surgery, which is worth of further clinical application and promotion.
