1- Definition• Any bleeding from uterus that differs

materially from that of the normal menstrual cycle in frequency of occurrence, in amount or in duration of flow.

• It applies to both menstrual and non menstrual disturbances due to– Organic disease either benign or malignant– Or to systemic or psychogenic origin

• Between menarche and menopause, almost every woman experiences one or more episodes of abnormal uterine bleeding.

2- Clinical types of abnormal uterine bleeding

Menorrhagia (hypermenorrhoea)Cyclical menstrual bleeding excessive in amount

and/ or prolonged in durationCauses:

Uterine fibroids Complication of undiagnosed pregnancy Adenomyosis Endometrial hyperplasia Malignant tumours Endometritis Dysfunctional bleeding

2- Clinical types of abnormal uterine bleeding Hypomenorrhoea (cryptomenorrhoea)

An abnormally small amount of menstrual flow usually spotting

Causes: Cervical stenosis Congenital transverse vaginal membrane Asherman syndrome Endometrial tuberculosis

PolymenorrhoeaPeriods occurring too frequently, usually less than

21 days apart. Bleeding may or may not be abnormal in amount

Causes: anovulation (endocrine disorders)

2- Clinical types of abnormal uterine bleeding

Metrorrhagia (intermenstrual bleeding)Bleeding occuring at any time between

menstrual periods ranging from slight spotting to haemorragic flow and from a single short episode to bleeding that continues for days

Causes: Endometrial polyps Endometrial and cervical cancers Exogenous oestrogen administration

2- Clinical types of abnormal uterine bleeding Menometrorrhagia

Uterine bleeding totally irregular in frequency and duration of episodes and excessive in amount.

Causes: Complications of pregnancy (abortion, hydatoform

mole, choriocarcinoma) Malignant genital tract tumours

OligomenorrhoeaMenstrual periods that occur more than 35

days apart. Bleeding usually decreased in amount and duration

Causes: Menopause, Anovulation, Pregnancy complications, Oestrogen-producing tumors

2- Clinical types of abnormal uterine bleeding Contact bleeding

Self-explanatoryCauses:

Cervicitis Cervical cancer Cervical eversion (ectropion) Cervical polyps

Amenorrhoea Failure to menstruate which is:

Physiology (before puberty, during pregnancy, puerperum and after menopause)

Pathological Primary amenorrhoea: congenital malformations, genetic

disorders. Secondary amenorrhoea

2- Clinical types of abnormal uterine bleeding

DysmenorrhoeaPainful menstruation, the commonest

gynaecological complaint, and leading cause of absenteism primary dysmenorrhoea: idiopathic causes (theories) secondary dysmenorrhoea: organic disease (PID,

endometriosis, fibroids, ...)

3- Evaluation of abnormal uterine bleeding Clinical history

Many causes of bleeding will be strongly suggested by history alone.

Note amount of flow, duration of cycle, duration of periods, number of episodes, LMP, menopause and any change in general health

Physical examinationGeneral health conditionGlandsAbdominal massesSize of the uterus/ovariesCervix

Evaluation of abnormal uterine bleeding

InvestigationsPap smearEndometrial BiopsyHysteroscopyD & CHormonal assaysUltrasoundLaparoscopy

4- General principles of management

A careful clinical history, physical and pelvic examination are vital.

Improved diagnostic technics and treatment have resulted in better care of patients with abnormal uterine bleeding.
