Transvaginal ultrasound
Definition:
Transvaginal ultrasound is a method of imaging the genital tract in women. The ultrasound machine sends out high-frequency sound waves, which bounce off body structures to create a picture. With the transvaginal technique, the ultrasound transducer (a hand-held probe) is inserted directly into the vagina. It is therefore closer to pelvic structures than with the conventional transabdominal technique (with the probe on the skin of the abdomen), providing superior image quality. This test can be used during pregnancy. (See also pregnancy ultrasound.) Text Continues Below
Alternative Names:
Endovaginal ultrasound How the test is performed:
You will be lying down on a table. The transducer is a long probe, covered with a condom and a sterile lubricant, that is inserted into the vagina. The health care provider will then move the probe within the vaginal cavity to scan the pelvic structures. How to prepare for the test:
The examination is done with your bladder empty. Sometimes, a transabdominal ultrasound is done just before a transvaginal ultrasound to look at organs in your abdomen. If so, you may be asked to drink several glasses of water without voiding before the transabdominal exam. Then, you will be asked to empty your bladder after the transabdominal test and before the transvaginal exam. How the test will feel:
There may be mild discomfort from the pressure of the vaginal probe. Why the test is performed:
Transvaginal ultrasound is used to evaluate a variety of abnormalities of the female genital tract. Some of these include the endometrium of women with infertility problems or abnormal bleeding; sources of unexplained pain; congenital malformations of the uterus and ovaries; ovarian tumors and cysts; possible pelvic infection; and causes of infertility. Transvaginal ultrasound is also used during pregnancy to identify normal intra-uterine pregnancy; ectopic pregnancy; fetal heartbeat; and many abnormalities of the uterus, placenta, and associated pelvic structures that are incompletely seen with conventional transabdominal ultrasound.
