Laser Fibre Deterioration and Loss of Power Output During Photo-Selective 80-W Potassium-Titanyl-Phosphate Laser Vaporisation of the Prostate

Fibre deterioration caused significant reduction of power output during PVP. This finding is an explanation for the often observed decreasing efficiency of tissue ablation and may also be responsible for some of the typical drawbacks and complications of PVP. Hence, improvements in fibre quality are necessary to advance the efficiency of this technique.
