Endometrial laser ablation is most commonly treated with which laser?

• A. Er:YAG
• B. Nd:YAG
• C. CO2
• D. KTP

Answer: (B)

Endometrial laser ablation relies on delivering energy that penetrates enough to destroy the endometrium while controlling bleeding. The Nd:YAG laser delivers energy at 1064 nm, which penetrates deeper into tissue than the other common endometrial lasers. That deeper penetration promotes coagulative destruction of a larger volume of endometrial tissue in a controlled manner, yielding effective ablation with good hemostasis. In contrast, CO2 and Er:YAG lasers are highly absorbed by water and produce very superficial vaporization or cutting, limiting how deeply they affect the endometrium and often requiring multiple passes. KTP provides good superficial coagulation but does not reach as deeply, making it less reliable for comprehensive endometrial destruction. So the Nd:YAG laser is favored for endometrial laser ablation because its deeper tissue interaction achieves thorough endometrial destruction with effective bleeding control.
