Laser pulse shapes influenced laser efficiency in stone disintegration

Study: Influence of the laser pulse shape on the treatment of stones in the upper urinary tract

Urinary stones can be successfully treated using a Holmium:Yttrium-Aluminum-Garnet (Ho: YAG) laser. The success rate of laser lithotripsy is influenced by laser pulse energy, frequency, and pulse width other than stone-related factors. The influence of the pulse shape on the success of the laser’s efficiency is unclear.

The findings of the study highlighted that different pulse shapes influence the disintegration of stones in the upper urinary tract. Modified laser pulse shapes, such as those offered by the Ho:YAG Dornier Medilas H Solvo 35 laser, can improve efficiency and reduce operating time. Thus, with the availability of such laser pulse shapes, the surgeon has the advantage of an additional pulse variable, ultimately affecting the planning of the lithotripsy session.
