Prévention de l’hyperthermie au cours de la lithotripsie laser en endourologie

Abstract

Introduction: Laser lithotripsy is a key method for breaking down urinary stones, utilizing the heat from the laser. However, inappropriate management of this heat can cause significant thermal damage. This document explores these thermal dynamics and their consequences.Materials and Methods: After a review of the fundamental principles of laser lithotripsy, a critical examination of relevant experimental and clinical research is conducted. This approach allows for a synthesis of current knowledge on the impact of laser operational parameters on urinary tissues.Results: The roles of conduction and convection principles in the propagation and dissipation of heat are highlighted. The concept of thermal dose for assessing thermal risks, comparisons between different types of lasers (Ho:YAG and TFL), and the variations in temperature induced by laser lithotripsy in various experimental and operational contexts are discussed.Conclusion: Becoming aware of the risks and deepening the understanding of the interaction between lasers and urinary stones and surrounding tissues are essential first steps in preventing complications.
