The Dormia® DualPerc is a novel stone retrieval basket that can easily and repeatedly be converted between rigid and flexible configurations during the same PNL, thereby removing the need for multiple devices for fragments' extraction and encouraging the use of the flexible nephroscope in addition to the traditional rigid nephroscope. The aim of the present work was to assess safety and performance of the Dormia® DualPerc in two preclinical models. METHODS: The Dormia® DualPerc, 4.8F in diameter for mini-PNL, 7F in diameter for standard PNL, was tested for performance and safety in 2 porcine models in 2019 (after having obtained approval from the Animal Ethical Committee) and in 2 adult human fresh cadavers in 2021. The rigid configuration was compared with the Cook Perc N-Circle tipless stone extractor, while the flexible configuration was compared with the Coloplast Dormia EXN7 device., used in standard PNL. Primary endpoints were safety and efficacy of the device during stone removal. Questionnaires administered to 4 investigators with medium to high experience in endourology for urolithiasis and no previous experience with that basket were used to establish useability and satisfaction of this new device. RESULTS: Successful stone removal occurred in all configurations both in the cadaver and pig models. Investigators working on both cadaveric and animal models experienced equal or lower time to grasp stones compared to competitive devices. No adverse events (in particular, perforation of the collecting system or tissue/close organ damage) were reported. Results from questionnaires demonstrated favorable ease of use and performance of the Dormia® DualPerc device, which was confirmed as easy to learn and intuitive to maneuver. CONCLUSIONS: The Dormia® DualPerc was shown effective and safe through our two preclinical settings. As a 2-in-1 stone retrieval basket for PNL, it competitively removed stones when compared to the alternative classical approach using 2 devices. Future studies will confirm safety and performance in clinical trials and explore time and cost saving.
