Desing and realization of a computer-assisted nephrostomy guidance system

Background and purpose: Nowadays, computerized nephrostomy techniques exist. Although relatively safe, several factors make it difficult for inexperienced users. A computer-assisted nephrostomy guidance system has been studied to increase the success rate of this intervention and reduce the work and difficulties encountered by the actors. Methods: To design the system, two methods will be studied. Following this study, this system was designed based on method 2. SmartSysNephro is composed of a hardware part whose manipulations made by the user are visualized and assisted by the computer. This nephrostomy procedure that the user simulates is monitored by webcam. Using the data from this Intel Real Sense webcam, allowed to propose a CNN YOLO model. Results: The results obtained show that the objectives set have been achieved globally. The SmartSysNephro system gives real time warning when the surgeon deviates from the standard workflow. It allows monitoring of the nephrostomy procedure via webcam. It is therefore relying on tracking, and it also has the potential to identify workflow tasks in video using the YOLO model. Conclusion: SmartSysNephro shows that the skills of the users can be greatly improved during the intervention because they will benefit from the assistance of the end-to-end system. Therefore, the success rate of nephrostomy increases, and the difficulties encountered by the actors decrease considerably.
