Paper Abstract

Application of lasers as cutting or coagulation instruments is based on the conversion of light energy into heat in the irradiated tissue. The extent and degree of the thermal action depends on the beam geometry and the energy of the incident light, as well as on the optic and thermal properties of the tissue. The extinction behavior in the tissue differs for the various laser systems employed in medicine. A comparison is made with Nd:YAG laser and those of the argon and CO2 types. For the transurethral use of laser beams in urology a special lasercystourethroscope has been developed. This is a modified Albarran attachment using a highly-flexible quartz fiber to transmit the laserlight. The proximal end of the light conductor is used without any sealing window and can be bent through up to 800.
