Study summary

Thuflep TLF: initial experience and results of prostate laser enucleation with fibrous thulium laser (TLF)

Read the detailed description

While prostate laser enucleation is being confirmed as the new gold standard for surgical management of benign prostate hypertrophy, the holmium:Yag laser is currently the most widely used. A new laser technology, the fibrous thulium laser (TFL), has recently appeared with clearly superior results for lithotripsy. The question therefore arises of the surgical and functional results of the use of fibrous thulium for prostate enucleation.
