Treatment tried


Irregular bleeding in peri-menopausal women (>45y) -    Refer to DIRECT ACCESS HYSTEROSCOPY

Irregular bleeding in women <45y                              -              Refer to the MENSTRUAL DISORDERS CLINIC


Offer pelvic ultrasound for women with irregular bleeding if any of the following apply:

·         the uterus is palpable abdominally

·         the history or examination suggests a pelvic mass

·         examination is inconclusive or difficult, for example in women who are obese

·         significant dysmenorrhoea (period pain)

·         a bulky, tender uterus on examination that suggests adenomyosis

·         for women who decline hysteroscopy, consider a pelvic ultrasound, explaining the limitations of this technique for detecting intracavitary causes of HMB (pelvic USS can miss about 50%of treatable pathology)
