During the last decade, the use of laser technology has become more common in operative gynaecology. Fibre lasers, such as the Nd:YAG, Thu:YAG, and diode lasers combine vaporisation and/or coagulation effects within the same operating instrument. Time-consuming changes of instruments during the procedure are unnecessary. Lasers can be used together with the colposcope for the treatment of cervical intraepithelial dysplasia and condylomata or are employed through laparoscopic technique, with the aid of modern microvideofacilities. Using the hysteroscopic technique, lasers has also been introduced
for treating intrauterine conditions as endometrial disease.
