Assessments
Adenomyosis was diagnosed as the maximal junctional zone thickness
(JZmax) ≥12 mm, JZmax/entire myometrium
> 40% and the difference between the maximum and minimum
> 5 mm thick based on MRI7,10.
Adenomyosis-caused dysmenorrhea was defined as the clinically recorded
patient-reported pain during the menstrual cycle11.
Adenomyosis-caused menorrhagia was defined as the clinically recorded
patient-reported heavy or prolonged menstrual
bleeding12. The
relief of dysmenorrhea and menorrhagia was defined as patient-reported
symptom relief of dysmenorrhea and menorrhagia within 12 months after
FUAS. The recurrence was defined as
patient-reported dysmenorrhea and/or menorrhagia after 12 months
following a period in which the symptomatic relief lasted for at least 3
months after FUAS. The uterine volumes and the lesion volumes of
adenomyosis were calculated using the following formula:
0.52*length*anteroposterior diameter*transverse
diameter13.
