What is it about?

This article describes a Delphi consensus project aimed at developing a standardized tool to evaluate flexible ureterorenoscopes (fURS). The project involved a three-stage approach, including a systematic scoping review to identify key parameters for evaluating fURS, defining evaluation categories and subcategories, and selecting an expert panel. A modified Delphi consensus project was then conducted to obtain consensus on the relevance and exact definition of each subcategory and the evaluation method. The TULIP tool was created as a result of the project, which is a user-friendly, efficient, and reproducible grading tool for evaluating fURS. The project was successful, reaching consensus at a predefined threshold of 80% high agreement.

Why is it important?

This research is important because it aims to develop a standardized tool to evaluate flexible ureterorenoscopes (fURS), which are medical devices used in endourology procedures. The study uses a three-stage consensus building approach based on the modified Delphi technique to identify and define key parameters and subcategories necessary for evaluating fURS. The resulting tool, called the TULIP tool, provides a user-friendly, efficient, and reproducible grading system for evaluating fURS, which can facilitate future comparison of outcomes and create uniformity in this field of research. Key Takeaways: 1. A systematic scoping review was conducted to identify key parameters used to assess the quality of fURS, resulting in the identification of five main categories: Manoeuvrability, Optics, Irrigation, Handling, and Durability. 2. The modified Delphi consensus project was conducted to reach consensus on the relevance and exact definition of each subcategory necessary to evaluate fURS, as well as the evaluation method of those subcategories. 3. The TULIP tool was created as a result of the consensus project, which provides a user-friendly, efficient, and reproducible grading system for evaluating fURS. 4. The study's expert panel consisted of 30 experienced endourologists from some of the most eminent endourology working groups in Europe and North America, and consensus was set at a threshold of minimum 80% high agreement.
