This deflection can be further compromised when various tools are inserted through the working channel and lower calyces are approached. The aim of our in-vitro study was to compare the single-use and reusable fURSs in a training simulation model (K-box) regarding their abilities of reaching simple and difficult lower pole calyces. METHODS Using the K-Box (Porges-Coloplast, France), four single-use (LithoVue, Boston Scientific, USA; Pusen, China; NeoFlex, Neoscope, USA; YouCare Technology, China) and four reusable (URF-V2, Flex Xc, Cobra vision, Boa vision) digital fURSs were compared for their deflection capabilities accessing a simple and a difficult lower pole calyx. The exercise was done with the working channel empty and with various tools inside the working channel (200μm, 273μm, 365μm laser fibres; 1.5Fr, 1.9Fr, 2.2Fr baskets; 0.038″ PTFE, 0.035″ Terumo guidewires; Piranha grasper). Tools were inserted through the deflected tip with scope in the calyx. Following this, the fURS's tip was straightened and the calyx was accessed again. The success or failures to access the lower pole were recorded. Each attempt was performed 5 times and if unsuccessful, a more experienced urologist repeated the manoeuvre. A simple ranking system was created, with one point given to every successful task (with a maximum score of 20). RESULTS The results of the deflection capability are as shown in Figure 1. LithoVue was the most successful disposable fURS and Flex Xc was the most successful reusable fURS. While almost all fURSs were able to access the simple calyx, the difficult calyx was accessible by only Flex Xc (of the reusable fURSs) and most disposable fURSs except YouCare Tech. The general ranking was better for disposable fURSs although there was a wide variability with individual tasks (Fig.1,2). CONCLUSIONS Our study showed a wide variation in fURS deflection, with LithoVue being the most successful disposable fURS and Flex Xc being the most successful reusable fURS. These findings are going to be useful for simulator training in K-box and potentially in clinical use, although in-vivo testing would be required for the later. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e477-e478 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Laurian Dragos More articles by this author Sandra M.
