The main purpose of a woman’s vaginal ultrasound is to check for pelvic pathology, ovarian disease, ectopic pregnancy and other conditions. Transvaginal ultrasound, or transvaginal ultrasound, is an examination method in which a probe is placed into the vaginal fornix to observe the internal organs and tissues of the female pelvis. Compared with traditional abdominal ultrasound, there is no need to fill the bladder and the images formed are clearer. Clinically, transvaginal ultrasound is commonly used to check for pelvic space-occupying lesions, such as uterine fibroids, uterine adenomyosis, pelvic effusion, etc.; it can also be used to check for ovarian diseases, such as ovarian cysts and tumors, etc.; in addition, it can also be used to diagnose early pregnancies, ectopic pregnancies, and so on. It is a commonly used test in obstetrics and gynecology. It should be noted that urination should be performed before the examination, and it is recommended to choose the way of examination under the guidance of the doctor.
