Konzeption und Evaluation eines Endoskopie-Simulators für die Urologie

UROTrainer – an endoscopic simulator for virtual diagnosis and therapy in the bladder BACKGROUND With respect to stimulate training operation procedures an European project named MISSIMU (Minimally Invasive Surgery SIMUlator) set an objective to develop a prototype of a cystoscopic virtual simulator based on real images data. METHODS On the base of 350 video documented cystoscopies with its diagnostic and therapeutic interventions, the observations of these procedures and in discussion with the operating surgeons two major training priorities were extracted to implement into a simulator. Together with physical and geometric parameters selected images data formed the database for the development of the virtual reality bladder simulator. The first prototype was evaluated by 20 urologists of the university clinic Grosshadern, Munich by a questionnaire. RESULTS Two major training priorities were realized. The first step included the inspection of the whole bladder wall and second the most utilized intervention the resection with the resection loop. With every training session various tumours on different parts of the bladder wall are posed, so that every new training session creates a new virtual patient. For intervention the user can choose either a resection loop or a laser fibre. The training feedback includes the percentage of the inspected bladder surface, of the resected tumour mass and the time needed for cystoscopy. As a result of this evaluation can be stated, that the basic procedures of cystoscopy can be well trained on a very realistic operation background. CONCLUSIONS The simulator is a suitable link between the surgical theory and the treatment on patients. This tool can increase the learning curve of residents and students on a virtual simulator without any risk for patients.
