Rise in intraluminal temperature during ureteroscopy: Is this a concern?

Area of Science:

• Urology
• Medical Technology
• Laser Surgery

Background:

• Increasing prevalence of urolithiasis necessitates minimally invasive treatments.
• Advancements in laser technology, including holmium YAG and thulium fiber lasers, have improved upper urinary tract stone management.
• High-power laser lithotripsy carries a risk of thermal injury to urothelial mucosa.

Purpose of the Study:

• To review strategies for mitigating thermal injury during laser lithotripsy.
• To enhance patient safety in retrograde intrarenal surgery.

Main Methods:

• Narrative review of existing literature.
• Analysis of thermal effects of laser lithotripsy.
• Exploration of various heat mitigation techniques.

Main Results:

• Laser lithotripsy converts significant energy to heat, risking thermal damage.
• Intrarenal temperatures can exceed cellular injury thresholds, especially in confined spaces.
• Multiple strategies exist to reduce thermal injury.

Conclusions:

• Optimizing laser settings, irrigation, and employing novel methods are crucial for safety.
• Understanding and implementing these strategies can improve outcomes in laser lithotripsy.
• Further research into heat mitigation is essential for advancing minimally invasive urological procedures.
