RESUMO
Abnormal uterine bleeding [AUB] is a common disease which can lead to several somatic and psychiatric problems. In the other hand, the causes of AUB seems to be different in virgin patients under 40 years old comparing to married women. So we decided to study the findings of transabdominal sonography in virgin patients under 40 years old with AUB. Two hundred virgin patients under 40 y/old with AUB were studied. At first, the type of AUB, the duration of disease and previous history were registered and then transabdominal ultrasound was done by two separated radiologist with a Gynecologist, logic 500 ultrasound system with 3.5 MHZ convex probe and sonographic findings were recorded. Ultrasound was normal in 49.5% and abnormal in 50.5% of patients. Ovarian findings were more common than uterine findings and were seen in 46% of patients but uterine abnormal findings were seen in only 12.5% of patients. [In some patients, ovarian and uterine abnormal findings were seen together]. The most common sonographic findings including: absence of dominant follicle in ovaries [25%] and then ovarian cyst [19.5%] and polycystic ovary syndrome [13.5%] and endometrial hyperplasia [8.5%]. By the way, the most common types of AUB were oligomenorrhea [56%] and hyper menorrhea [25%]. In patients with oligomenorrhea the most common abnormal findings were absence of dominant follicle [35%] and PCO [21%] and in patients with hypermenorrhea were ovarian cyst [22%] and absence of dominant follicle [10%]. In our study, ultrasound was normal without any detectable sonographic abnormality in about half of the patients. The cause of AUB in these patients, seems to be dysfunction, may be due to Psychiatric problems and stresses. Among the pathologic findings, absence of dominant follicle due to an ovulation [dysfunction] is the most common finding and uterine pathology is less common. According to all findings, it seems that in virgin patients under 40 old with AUB, dysfunction due to stress and Psychiatric problems is the main reason and therapeutic management should be relay on it
