Lithium Triborate-Laser Vaporisation of the Prostate using the 120W High Performance System (HPS) Greenlight-Laser: High Performance all the Way?

Despite technical refinements of the 120 W lithium-triborate laser fiber degradation and significantly decreased power output are still detectable during the procedure. Laser fibers are not fully appropriate for the high power delivery of the new system. There is still potential for further improvement in the laser performance.
