Vaginal ultrasound, as the name suggests, is an ultrasound examination through the vagina, which examines the body of the uterus, fallopian tubes, ovaries, cervix and pelvis. The small examination of these areas can clearly diagnose the presence of fibroids, ovarian cysts, cervical cysts, abnormal endometrial hyperplasia and pelvic inflammatory disease. Vaginal ultrasound is very simple and quick because it does not require holding urine, which helps patients save time. However, vaginal ultrasound is not suitable for women who are menstruating or have severe cervical erosion or severe vaginal lacerations. This is because the ultrasound probe is placed directly into the vagina, which can lead to serious intrauterine infections if you are menstruating. In case of severe cervical erosion, the probe may cause a lot of cervical bleeding when it touches the cervix during the ultrasound, and in case of vaginal lacerations, the patient may experience severe pain after the probe enters the vagina. Therefore, women with these symptoms should not undergo vaginal ultrasound. The results of a vaginal ultrasound are clearer than those of an abdominal ultrasound, especially in the early stages of pregnancy when ectopic pregnancy is identified. It is also not very painful and takes only about 10 minutes to perform. Of course, unmarried women who have never had sex before are not allowed to have vaginal ultrasound.
