Introduction

During an abdominal B-ultrasound examination, the probe is placed on the lower abdomen, and sound waves are transmitted through a coupling agent to generate images. Prior to the examination, the patient should retain urine to fill the bladder, which helps displace the intestines and allows for a clearer view of the uterus and fibroids. This method is suitable for unmarried women, individuals without a history of sexual activity, and those who have concerns about vaginal examinations. The procedure is relatively simple and non-invasive; however, the ultrasound must penetrate multiple layers of tissue, including the abdominal wall and bladder.

Generally speaking, both abdominal ultrasound and transvaginal ultrasound have their own advantages for uterine fibroid examination, and the choice depends on specific circumstances. If in doubt, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

During an abdominal ultrasound examination, the probe is placed on the lower abdomen, and sound waves are transmitted through a coupling agent to generate images. A full bladder is required before the examination, achieved by holding urine, to push the intestines aside and allow clear visualization of the uterus and fibroids. This method is suitable for unmarried women, individuals without a history of sexual activity, and those who are concerned about vaginal examinations. The procedure is relatively simple and non-invasive. However, as the ultrasound must penetrate multiple layers of tissue such as the abdominal wall and bladder, the image clarity may be affected in obese individuals or when fibroids are located deep within the uterus. Small fibroids may be missed during this examination.

Transvaginal ultrasound involves inserting the probe into the vagina, which allows closer proximity to the uterus and adnexa. No need to hold urine is required, and this method can provide clearer visualization of the uterine muscle layer and fibroid details, including the size, location, and blood supply of the fibroid. It is particularly effective in detecting small fibroids, submucosal fibroids, and fibroids near the cervix. However, this procedure is invasive and is not suitable for women with an intact hymen, women during menstruation, or those with vaginal inflammation or other conditions that make vaginal procedures inappropriate.

Prior to undergoing a uterine fibroid examination, it is important to inform the doctor about your personal circumstances, such as whether you are sexually active and where you are in your menstrual cycle. If there are any questions regarding the examination methods, communicate promptly with the doctor and choose the most appropriate method based on your individual condition to ensure an accurate diagnosis.
