This study explores the application of three-dimensional(3D) printing technology combined with PACS in the standardized training of residents in urology. For the residents who received phase Ⅱ standardized training

they were guided to observe and analyze CT images

3D CT reconstruction data

and 3D printing entity during teaching; with reference to the cases of kidney tumors

the 3D printing entity model was explained to help the trainees learn the characteristics of the disease and formulate the operation plan of partial nephrectomy; an explanation of the actual surgical procedure gave them a deeper understanding of the anatomical characteristics and treatment regimens of the disease. The preliminary results of practice show that the application of 3D printing technology combined with PACS can enable residents to grasp the anatomical characteristics of renal tumors within a short time and deepen their understanding of surgical procedures and techniques. This teaching method holds promise for application in clinical specialties.
