This paper presents a design for a computer aided surgical (CAS) system with a voice user interface (VUI) using Sami, a purpose-designed CAS system with VUI. Then, during Ureteroscopic surgery, we compare conventional UI -- as performed at the National Cheng Kung University Hospital (NCKUH) -- and the VUI of Sami. We invited three surgeons from NCKUH to participate in a Wizard of Oz test (WOZ test). Subsequently, the doctors were asked their opinion of Sami. At the end of the design process, the system framework of Sami was defined and programmed using Java. In the usability test, Sami demonstrated that the three surgeons could control the interface without using their hands, allowing them to see the nidus of the patient and administer the treatment. In the comparison results, the surgeons gave higher scores for convenience and speed to the VUI than to the conventional UI.
