Dysfunctional uterine bleeding is defined as abnormal bleeding from the uterine endometrium, which is unrelated to anatomic lesion. According to definition, dysfunctional uterine bleeding seems to be exclusive term.
The problem of abnormal uterine bleeding is the most frequent problem of all gynecologic diseases and may occur on any age, from menarch to menopause, but occurs more frequent especially on puberty and menopause. It may occur in an ovulatory
cycle,
although it is more commonly associated with an anovulatory one.
139 cases of dysfunctional uterine bleeding were evaluated on clinical and pathologic aspects, and we performed brief review of literature.
1. Age distribution of DUB was localized mainly in 30-40 years, and mean age was 41.5 years.
2. Dysfunctional uterine bleeding patients were mainly multigravidas, and showed 2-3 times deliveries and 5-6 times pregnancies.
3. Among variable bleeding patterns, intermenstrual bleeding(42%) was the most common pattern and the next was menorrhagia(30%).
4. Histologic findings of endometrium were proliferative phase, 76 cases(55%), secretory phase, 42 cases (30%), and hyperplasia, 8 cases(6%) in order of frequency.
5. According to endometrial biopsy, the incidence of anovulatory DUB was 71%(59 cases out of 83 cases) and ovulatory DUB was 29%(24 cases out of 83 cases).
