Summary
The holmium: YAG laser offers precise, superficial tissue ablation with minimal thermal damage, making it a safe and effective tool for various urological conditions and stone fragmentation.
Area of Science:
- Urology
- Surgical Technology
- Laser Physics
Background:
- The holmium: YAG laser is a pulsed laser emitting at 2100 nm, combining cutting and coagulation properties.
- Its wavelength is transmittable via optical fibers, ideal for endoscopic surgical applications.
Purpose of the Study:
- To review the physics of the holmium laser.
- To examine its laser-tissue interactions.
- To detail its applications in treating urological diseases.
Main Methods:
- A comprehensive literature review was conducted.
- The review focused on holmium laser physics and urological applications.
Main Results:
- Holmium laser light is strongly absorbed by water, enabling superficial tissue ablation.
- Precise incisions with a minimal thermal injury zone (0.5–1.0 mm) ensure adequate hemostasis.
- Key urological applications include stricture incision, tumor ablation, prostate procedures, and lithotripsy.
Conclusions:
- The holmium: YAG laser is a versatile surgical tool effective for soft tissue applications and stone fragmentation.
- Its safety and efficacy are well-established in urology.
- Increased utilization in urology is expected due to its advantageous features.
