A transvaginal ultrasound is a type of pelvic ultrasound used by healthcare providers to examine the female reproductive organs. A transvaginal ultrasound procedure sends sound waves through a probe inserted into the vagina. The ultrasound probe is placed in the vagina and can evaluate the bladder, uterus, fallopian tubes, ovaries, cervix, and vagina. This is an internal examination. The ultrasound test takes about 30-60 minutes. A transabdominal ultrasound is an alternative option.
Transvaginal ultrasound is usually done if an abnormality is found during a pelvic or abdominal exam, there is pelvic pain or unexplained vaginal bleeding, to check for ovarian cysts or uterine fibroids, checking placement of an IUD or for evaluation of infertility.
Transvaginal ultrasound may also be used during pregnancy for evaluation of the cervix or placenta, to identify the source of any abnormal bleeding or to check for possible miscarriage or ectopic pregnancy.
