ABSTRACT

Objective To investigate the effectiveness of Uromentor virtual reality simulator in flexible ureteroscopy training for catechumen.Methods Fifty-one catechumen were selected.After 1 hour training of basic operation in Uromentor virtual reality simulator, all trainees performed special-purpose exercise ( kidney inspection with flexible ureteroscopy ) for 3 hours. Using right kidney inspection, a preliminary assessment for each trainee was made before the special-purpose exercise and data such as total time, number of trauma from the scopes and tools, percentage of kidney surface examined and global rating scale ( GRS ) were recorded.The same assessment was performed once again after the special-purpose exercise ( secondary assessment ) , and data were recorded and compared to the preliminary assessment. Results Each trainee made a significant improvement in flexible ureteroscopic skill after the special-purpose training.The parameters such as total time, number of trauma from the scopes and tools, percentage of kidney surface examined and GRS of all trainees in preliminary assessment were 14.63 ±1.01 min, 8.62 ± 2.67, 51.05%±20.79%and 10.31 ±2.53, respectively;while in secondary assessment, parameters were 7.71 ±1.13 min, 1.67 ±1.23, 98.04% ±5.42% and 29.14 ±3.01, respectively.The differences between the preliminary assessment and the secondary assessment of each parameter were significant ( P<0.01).Conclusions The Uromentor virtual reality simulator can improve the trainee′s skills of flexible ureteroscopy.It is a good instrument of the flexible ureteroscopic training for catechumen.
