Endocorporeal Laser Lithotripsy (ELL) was firstly described in 1992, having the Holmium: Yttrium-Aluminium-Garnet(Ho: YAG) pulsed laser as a pioneer in the field and then, turning into the current gold standard laser for this procedure. Thanks to the technological advances, nowadays we have a new pulsed laser gaining access in ELL, the Thulium Fiber Laser (Tm-Fiber). Tm-Fiber laser has arrived to, perhaps, become the new gold standard.
