although it is more comonly 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.
@ES the results were as follows:
@EN 1. Age distribution of DUB was localized mainly in 30~40 years, mean age was 41.5 years.
2. Dysfunctional uterine bleeding patients were mainly multigravidas(mean gravidities ; 5.2 times, mean parities; 2.6 times).
3. Among various bleeding patterns, intermenstrual bleeding was the most common pattern(42%) 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 93 cases) and ovulatory DUB was 29% (24 cases out of 83 cases).
