Abstract

Interstitial Nd-YAG laser irradiation has been successfully applied using an endo rod. The rod conected directly to a quartz fiber is made out of new ceramics and is driven into tumor under direct vision. The irradiation effect can be distinguished by a whitish dis-coloration of the cancer. This operation has been performed in 25 cases. In conclusion, it is considered to be a method, comparing conventional transurethral surgery, that the follow-ing advantages can be mentioned: 1. low laser energy is sufficient, 2. it can be applied also to large tumors (more than 3 cm in diameter), 3. damage to the surrounding tissue like an ureteral orifice is very slight, 4. there is no risk of bleeding and perforation, and 5. the technique is simple to practice and easy to manipulate.
