| Outline of Final Research Achievements |
With recent technologic advances in urologic endoscopy, ureteroscopy has become an important procedure for urologic treatment. However, controlling a flexible ureteroscope necessitates a certain level of expertise. Novice operators may lose their orientation during flexible ureteroscopy in patients with complicated pyelocaliceal shapes or poor visibility because of macrohematuria. A navigation system that helps surgeons to confirm the position of the ureteroscope in the pyelocaliceal system may increase the accuracy of procedures. We therefore developed an experimental model of a novel ureteroscopic navigation system that used a magnetic tracking device and evaluated the system by analyzing the accuracy of ureteroscopic navigation in a 3D pyelocaliceal system model. Use of our novel ureteroscopic navigation system improved the accuracy of ureteroscopic maneuvers in both novice and experienced surgeons, without using fluoroscopy.
