Summary

Holmium laser is the current gold standard for lithotripsy on urinary lithiasis, while Thulium is brand new. The latter has been released in July 2020 in Europe, and only in-vitro studies have been published. The aim of this study is to compare the stone free rate in ureteroscopy, for all consecutive patients treated with laser fragmentation, between both Holmium and Thulium lasers. The costs and complications will also be studied.
