Objectives: To investigate the clinical effects of transcervical interstitial microwave irradiation of adenomyotic tissues as an alternative to hysterectomy. Methods: Thirty-three patients who were candidates for hysterectomy for the treatm…

Microwave endometrial ablation at 2.45 GHz using a thin, curved microwave applicator for organic menorrhagia was developed more than 10 years ago. Since then, the number of patients who undergo this treatment has been gradually increasing. …

Objectives: Transcervical microwave adenomyolysis (TCMAM) along with microwave endometrial ablation (MEA) could replace hysterectomy for treating adenomyosis. Thus, we performed a feasibility study in the treatment of adenomyosis by simulta…

Objective: Microwave endometrial ablation is widely used instead of hysterectomy for menorrhagia. However, it can not be used for large myomas or deep adenomyosis. To treat myomas and adenomyosis, we developed a transcervical microwave abla…

Microwave endometrial ablation (MEA) is a low invasive technique for menorrhagia resistant to conservative therapy. Since preliminary results of microwave endometrial ablation at a frequency of 9.2 GHz were published in 1995, it has been wi…

AIM: We investigated microwave power and duration of use, which does not affect extrauterine organs, in order to treat organic menorrhagia caused by myomas or adenomyosis. METHODS: Electric fields around a microwave applicator at a frequenc…

Since microwave tissue coagulator became commercially available in 1982, it has been widely used for treating hepatomas. Some gynecologists did use the apparatus in laparoscopic salpingectomy for tubal pregnancy, tubal cautery for steriliza…

Adenomyosis can cause severe menorrhagia, which is a common indicator of the need for hysterectomy. None of the ablative techniques developed over the last two decades are of use in treating menorrhagia in a uterus enlarged by deep adenomyo…

A curved microwave applicator was specifically developed for microwave endometrial ablation for the uterus with distorted cavity. The applicator was transcervically introduced to a uterine cavity of a surgical specimen with an intramural my…
