Is adenomyosis associated with menorrhagia?

Area of Science:

• Gynecology
• Reproductive Medicine
• Medical Imaging

Background:

• The association between adenomyosis and menorrhagia lacks consensus in existing literature.
• Previous studies often involved retrospective analyses of highly selected patient groups, primarily those undergoing hysterectomy.
• There is a need for large, prospective studies in general gynecology settings to clarify this relationship.

Purpose of the Study:

• To investigate the association between adenomyosis and menorrhagia in a prospective observational study.
• To determine if the presence or severity of adenomyosis, as assessed by ultrasound, correlates with menstrual blood loss.

Main Methods:

• A prospective observational study conducted in a university teaching hospital's general gynecology clinic from January 2009 to January 2010.
• Included 714 consecutive premenopausal women who underwent clinical and transvaginal ultrasound examinations.
• Adenomyosis was diagnosed via ultrasound, and menorrhagia was assessed using direct questioning and pictorial blood loss assessment charts.

Main Results:

• Adenomyosis was diagnosed in 22.0% of participants.
• No significant association was found between the binary presence of adenomyosis and menorrhagia.
• A significant positive correlation was observed between the number of ultrasound features of adenomyosis and the amount of menstrual loss, with a 22% increase in loss per additional feature.

Conclusions:

• The presence of adenomyosis alone is not significantly associated with menorrhagia.
• A novel concept of classifying adenomyosis severity based on ultrasound features shows a correlation with menstrual blood loss.
• This severity classification warrants prospective evaluation in diverse populations to improve patient counseling and guide treatment strategies.
