A bench-top evaluation of the Ily® robotics assisted tele console system in ureteroscopy by medical students, residents and urologists: does prior videogaming experience help shape the learning curve?

ABSTRACT

PURPOSE: Previous studies have demonstrated an association between video-gaming experience (VGE) and improved robotics skills. We aimed to evaluate the initial learning curve for the Ily® robotics system (Sterlab, Sophia Antipolis, France) when applied to flexible ureteroscopy (FU) among both medical students and urology surgeons. METHODS: There were two groups, surgeons and students. An initial questionnaire was completed detailing basic demographics and experience. In part one, both groups performed two simple timed tasks using an Ily® mounted single-use RAU. In part two, group 1 repeated both tasks using a hand-held FU. A subjective assessment of comfort, intuitiveness and a NASA Task Load Index were then completed. RESULTS: There was a total of 28 participants. Among medical students with VGE (n = 9, 64%)., average calyceal inspection time was 185 ± 80 s; 133 ± 42 s; 121 ± 71 s. For non-gamers (n = 5, 36%), average times were longer at 221 ± 97 s; 134 ± 35 s; 143 ± 68 s respectively. Average calyceal inspection time for videogaming surgeons (n = 8, 57%) was 126 ± 95 s; 98 ± 40 s; 107 ± 71 s, respectively. For non-gamers average inspection times were longer at 150 ± 73 s; 114 ± 82 s; 111 ± 47 s, respectively. None of these differences achieved statistical significance. Surgeons trial speeds were, however, significantly faster by hand-held compared to RAU by 103, 81 and 82 s respectively (p < 0.05). CONCLUSION: These results show that ex- or current- video gamers do not have a significant advantage in time to perform FU. Any early advantage conferred to ex- or current- gamers may be rapidly overcome.
