The main two types of ultrasound examination for uterine fibroids are transabdominal ultrasound and transvaginal ultrasound, with the following cautions: 1. For transabdominal ultrasound, you need to drink and hold urine in advance, and your bladder needs to be filled with about 400ml, so that there will be a better sound transmission window and the ultrasound sound waves can examine the fibroids through the abdominal wall; 2. The bladder needs to be emptied in advance. The current high frequency vaginal ultrasound probe can detect smaller fibroids and other uterine adnexal lesions. Patients do not need to consider whether to have intercourse before the fibroid examination, but if there is vaginal bleeding and other conditions during the fibroid examination, it is recommended to avoid intercourse, as it may affect the observation of fibroids or cause vaginal inflammation, which may affect the examination results.
