Abstract

Neodymium YAG (Nd-YAG) laser is a new instrument for the treatment of various urologic disorders where coagulation is necessary but still limited in cases. It avoids many of the side effects of electrocoagulations. Nd.YAG Iaser is a safe and effective modality, reducing blood loss, shortening operation time and preserving functional integrity on remaining renal tissue. In this experiment, to investigate the Nd-YAG Laser effect to renal tissue and the adaptation to renal surgery were aimed. We made the experimental study on renal tissue damage according to the change of irradiation time and power of NJ-YAG laser. The following results were obtained; After irradiation of Nd-YAG laser, renal tissue damage was noted on 30 Watt, 3 seconds and 5O Watt, 1 second, and the degree of renal tissue damage was increased with in creasing of laser power and time. A 2mm depth injured renal tissue was noted on 150-250 Joules, which coagulates the vessel with several mm diameter. Judging from the results of this experiment it may be believed that Nd-YAG laser can be adaptable to renal surgery in bleeding control without severe renal tissue damage.
