Abstract
Uro Trainer (UT; Karl Storz GmbH, Tuttlingen, Germany), a virtual reality simulator for transurethral resection of prostate (TURP), has been infrequently validated. To ascertain the utility of such a trainer, we performed a basic face and content validity study. Ten experts and nine novices (done more than 50 and less than 3 TURPs, respectively) performed a TURP on UT and rated simulator usefulness (seven items), realism (five items), and overall score (one item) on a Likert's 10-point scale. Scores of < 6.0, 6.0 to 8.0, and > 8.0 on the Likert scale 1 to 10 were considered not, slightly, and highly acceptable, respectively. Novices rated UT as more helpful than experts in the following aspects of face and content validity: usefulness general (p = 0.0001, statistically significant), hand-eye coordination (p = 0.04, statistically significant), material knowledge and skills (p = 0.02, statistically significant), spatial skills (p = 0.003, statistically significant), cystoscopy (p = 0.002, statistically significant), TURP (0.002, statistically significant), visual aspects (p = 0.003, statistically significant), and overall score (p = 0.007, statistically significant). One item of usefulness (coagulation) and three items of realism...Continue Reading
