One-third of all gynaecological consultations are because of abnormal uterine bleeding (AUB). This proportion rises to more than 2/3rd when peri & post menopausal women are considered. In normal to 12 week size uteri, the cause of abnormal bleeding often remains obscure. Objectives (S) Clinical and hysteroscopic evaluation of the cervical canal & uterine cavity of 100 women with AUB to evaluate various causes of AUB in the study population. Method (S) 100 women with AUB and uterine size normal to 12 weeks pregnancy were subjected to clinical & hysteroscopic examination. The cause of bleeding was evaluated. Results Menorrhagia (30%), menometrorrhagia (16%), oligomenorrhea (16%) and postmenopausal bleeding (2%) were some of the indications for hysteroscopy. Intrauterine pathology was diagnosed in 74% of cases. Hyperplastic endometrium (30%) and mucus polypi (28%) were the most frequent findings. 13% of the cases had multiple finding. A surprising 7% had IUCD in their uteri without their knowledge, while bony spicules was found in 1 patient. Both patients with post menopausal bleeding had atrophic endometrium. Conclusion (S) Hysteroscopy can be easily learnt. It gives a clue to diagnosis in AUB and can reduce the burden of hysterectomy in many cases which can be treated by simple procedures.
