Advances in laser pulse modulations

Area of Science:

• Endourology
• Laser technologies
• Surgical innovation

Background:

• Pulse modulation technologies are emerging in endourology.
• These technologies alter laser-fluid-target interactions.
• Focus is on laser lithotripsy and endoscopic prostate enucleation.

Purpose of the Study:

• To review recent evidence on the clinical impact of pulse modulation in endourology.
• Specific focus on laser lithotripsy and endoscopic prostate enucleation.
• Evaluate advancements in laser-fluid-target interaction.

Main Methods:

• Review of preclinical models, in vitro experiments, prospective cohorts, retrospective comparisons, and randomized controlled trials.
• Analysis of advanced pulse-shaping strategies.
• Evaluation of technologies like Moses and Magneto.

Main Results:

• Preclinical data show improved fragmentation and retropulsion control.
• Clinical studies report comparable stone-free rates for laser lithotripsy.
• Modest advantages in operative efficiency and energy consumption noted.
• Prostate enucleation studies suggest improved hemostasis and efficiency, but not functional outcomes.

Conclusions:

• Pulse modulation technologies offer improved laser handling and efficiency.
• Superiority in hard clinical outcomes for pulse modulation remains unproven.
• Further clinical validation is needed.
