Paper Abstract

Laser lithotripsy is based on laser induced plasma formation. Successful stone fragmenting is dependent on power density at the fiber tip in contact with the stone and on the absorption of laser radiation by the stone itself. The use of the laser has been ineffective in the treatment of hard stones and of stones that absorb only minimal amounts of laser radiation. In our experimental and clinical studies we used Rifamycin (Rifocin) as a photosensitizer for the pulsed Dye laser and Sterile Indocyanine Green (Cardio Green) for the pulsed Alexandrite laser. We found that the use of these substances significantly increased the effectiveness of the laser in the treatment of those stones.
