Paper Abstract

We investigated a fiber-optic infrared radiation diagnosis for in vivo urinary tract tissue discrimination during laser urinary stone fragmentation. Such in vivo analysis may be useful for preventing mis-irradiation to surrounding tissue. Since we plan to use infrared lasers and infrared fibers to the urinary stones photofragmentation, the pulsed photothermal radiometry(PPTR) was employed in this study due to its simplicity and benefit of common use of the infrared laser and fiber to therapy and diagnosis. We successfully demonstrated a discrimination between urinary stones and urinary tract tissue, by a chalcogenide glass fiber-optic CO laser induced PPTR analysis.
