Prevalence of hysteroscopic abnormalities and anomalies observed in a population without gynaecological complaints

Objective

To investigate the prevalence of hysteroscopically observed abnormalities and anomalies in a population without gynaecological complaints.

Design

Analysis of the hysteroscopic observations in 503 patients who consented to have a hysteroscopic tubal occlusion attempt for sterilization (Ovabloc^R procedure).

Setting

Outpatient department of a general hospital.

Results

The prevalence of polyps was found to be 0.032, of fibroids 0.034, of intrauterine adhesions 0.040 and all Müllerian variations 0.152. The prevalence of fibroids and intrauterine adhesions was found to be age dependent. The incidence of Müllerian variations decreased as parity increased. Post-delivery and abortion curettage were a cause of intrauterine adhesions in only a minority of our patients.

Conclusions

In the hysteroscopic work-up of patients presenting with fertility problems and patients with abnormal uterine bleeding, one should consider the prevalence of intrauterine abnormalities and anomalies in asymptomatic women. Adhesions around the tubal orifices could be indicative of a tubal obstruction.
