Background: There are today a number of VR-simulators for practicing the TURP procedure, but few data on the effect of training on surgical performance.
Objective: To test if practicing the TURP procedure in a VR-simulator increases the skills and dexterity of urology residents when performing the procedure on patients. Design, setting and participants Twenty-four urology residents attended a five-day course on diagnosis and treatment of benign prostatic enlargement. Each of the residents did three video-recorded TURP procedures on patients.
Intervention: Between two of the procedures the residents underwent criterion-based practice in a TURP simulator (PelvicVision).
Measurements: The TURP procedure was peroperatively evaluated using objective structured assessment of technical skills (OSATS). The video-recordings of the procedures were analyzed on a minute to minute basis regarding the main action during that minute, if that action was successful, and errors.
Results and Limitations: The participating residents rated patient safety as high, they believed they learned most from the real operations, and they gained knowledge about both the procedure and the instrumentation used. The mean practice time in the simulator was 198 minutes before reaching the criterion level. Comparison of the first and last TURP procedures showed an increase in autonomous operation time and in successful actions and a decrease in hemostasis time without increased blood loss. The proportion of residents believed able to perform a simple TURP procedure increased from 10% to about 75%. OSATSscores and self-evaluations were significantly improved. The scores increased significantly more with than without simulator practice. The patient follow-up showed no increased risks or poorer results regarding micturition.
Conclusions: Practice in a simulator based environment improves the skills and dexterity of urology residents when performing the procedure on patients, without increased risks or poorer results for the patients.
