Can uterine polyps be seen with color ultrasound?

Uterine polyps can usually be discovered through color ultrasound. Uterine polyps are neoplasms formed by local proliferation of the endometrium or cervical mucosa. Color ultrasound examination can clearly show their location, size and morphological characteristics.

Transvaginal color ultrasound is the preferred method for diagnosing uterine polyps. The probe has a high frequency and is closer to the uterus, and can clearly display polyps with a diameter of more than 3 mm. Typical ultrasound findings are hyperechoic or isoechoic masses in the uterine cavity with clear borders, narrow bases, and partially visible blood flow signals. For cervical polyps, cord-like high echoes in the cervical canal can be observed on color ultrasound. Color Doppler ultrasound can also identify polyps and other lesions, such as submucosal fibroids, which show uneven internal echoes, and endometrial cancer, which shows irregular thickening with abundant blood flow signals.

When the polyps are too small or located in hidden locations such as the uterine horns, ordinary color ultrasound may miss the diagnosis. At this time, you can choose to reexamine on the 6th to 10th day of the menstrual cycle. At this time, the endometrium is thinner and it is easier to find lesions. Suspected cases can be combined with three-dimensional color ultrasound reconstruction or further confirmed by hysteroscopy. In postmenopausal women, the detection rate of color ultrasound will decrease due to endometrial atrophy.

After uterine polyps are discovered, they should be reviewed regularly to observe their growth and changes. Keeping the perineum clean at ordinary times, avoiding long-term use of estrogen drugs, and controlling weight can help prevent recurrence. If abnormal uterine bleeding or infertility occurs, it is recommended to go to a gynecologist promptly to evaluate whether surgical treatment is needed.
