Objective: To explore the application of modified fluid position pads in da Vinci robotic urology lateral position surgery and analyze its clinical application value. Methods: A randomized controlled study was conducted from June 2024 to June 2025 to select 120 patients from the First Affiliated Hospital of Sun Yat-sen University who met the inclusion and exclusion criteria and were randomly divided into 60 cases each in the control group and the observation group. The control group used the traditional position placement method, and the observation group applied the modified fluid position pads for position placement. The two groups were compared in terms of positioning process, patient comfort, position stability, and satisfaction of surgeons. Results: The comfort level of the patients in the observation group was higher than that of the control group, and the positioning process could save time compared with the control group. The position stability rate in the observation group was significantly higher than that in the control group. The satisfaction of surgeons in the observation group was also higher than that in the control group. Conclusion: The application of the modified fluid position pads significantly simplifies the positioning process, improves the comfort and position stability of the patients, and enhances the satisfaction of the surgeons, which has important clinical promotion value.
