Transvaginal sonography in gynecologic examination

Abstract

Objective To discuss the use of transvaginal sonography in gynecologic examination. Methods A total of 8869 female subjects were assigned to the aged group (≥56 years old, n=1406), middle group (36-55 years old, n=4801), and young group (≤35 years old, n=2662). Transvaginal sonography was used for uterus and adnexa scanning in these participants, and the results were analyzed. Results Of 4207 (47.44%) detected patients, uterine leiomyoma (n=2285, 25.76%), Nabothian cyst (n=1126, 12.69%), adnexal cyst (n=324, 3.65%), ovarian endometrial cyst (n=131, 1.47%), and adenomyos (n=129, 1.45%) were the most commonly seen gynecopathy.For the aged, middle, and young group, the gynecopathy detection rate was 25.39%, 64.42%, or 28.44%, respectively.The detection rates of those five diseases were significantly different among the three groups (P<0.05). For instance, the detection rate of uterine leiomyoma in the aged (37.12%) or middle (18.78%) group was significantly higher than the young group (8.98%; both P<0.05); while the detection rates of Nabothian cyst, adnexal cyst, and ovarian endometrial cyst in the young or middle group were significantly higher than the aged group (all P<0.05). Conclusions As a non-invasive test, transvaginal sonography could be easily used in gynecologic examination. Key words: Ultrasonography; Physical examinations; Gynecology
