Application of VR technology in standardized residency training of ureteroscopy in the department of urinary surgery
Objective To explore the application effect of virtual reality(VR)technology in standardized residency training of ureteroscopy in the department of urinary surgery.Methods Twenty residents without ureteroscopy experience who rotated in Department of Urinary Surgery,The First Affiliated Hospital of Chongqing Medical University from January to November 2023 were randomly divided into two groups,with 10 residents in each group.The traditional teaching group adopted the theory teaching combining skill training.The VR group utilized theory teaching combining VR-assisted skill training,where the process of ureteroscopy was simulated using VR helmet and handles.A skill examination and satisfaction survey were conducted after training to evaluate the teaching effect.SPSS 22.0 was used for the t-test and chi-square test.Results Compared with the traditional teaching group,the VR group required fewer cases of skilled operation[(3.40±1.00)cases vs.(7.70±1.00)cases]and shorter operation time[(2.70±0.67)min vs.(3.90±1.37)min](P<0.05).The VR group was significantly better than the traditional teaching group in the following dimensions:fluency of scope insertion[(2.30±0.82)points vs.(1.40±0.70)points],degree of mucosal injury[(2.20±0.92)points vs.(1.40±0.70)points],and operational proficiency under the ureteroscope[(2.40±0.70)points vs.(1.60±0.84)points](P<0.05);there were no significant differences between the two groups in proficiency level and visual field stability scores(P>0.05).The VR group had higher satisfaction scores in training method(80%vs.30%)and more confidence to carry out ureteroscopy independently(70%vs.20%).Conclusions Through simulated training with VR technology,resident trainees can significantly shorten the learning curve of ureteroscopy and improve teaching satisfaction.
