Moreover, flexible ureteroscopes is often considerably weakened each time a laser fiber is pulled back throughout the ureteroscope channel when the laser is activated. Xavier et al described a whole new engineering whereby the CMOS imager of the DUR-D digital flexible ureteroscope (Gyrus ACMI, Southborough, MA) was in the position to detect the coloured cladding of a laser fiber and get more info connect this info to an endoscopic safety technique that might flip from the laser Should the fiber was pulled back again inside the ureteroscope.
