Transvaginal ultrasound, also known as transvaginal ultrasonography, or just transvaginal ultrasound, is a diagnostic test that uses a small device that is inserted into the vagina and produces sound waves that are then transformed by the computer into images of internal organs, such as uterus, fallopian tubes, ovaries, cervix and vagina.
Through the images produced by this exam, it is possible to diagnose different problems of the pelvic region, such as cysts, infections, ectopic pregnancy, cancer, or even confirm a possible pregnancy.

In such cases, it is only advisable not to use the bathroom until the exam is performed.
