Comparison of laser fiber degradation and perioperative outcomes following holmium laser enucleation of the prostate using 550 and 1000 µm fiber diameters.

Use of the 1000 µm fiber resulted in significantly less fiber degradation, energy requirement, and total operative time during HoLEP, in spite of similar prostate size and time required for enucleation and morcellation. Different fiber diameters do not appear to affect post-operative blood loss or dysuria.
