Vaginal ultrasound is inaccurate two days before menstruation

Vaginal ultrasound is a commonly used examination method in gynecology and can be used to check the health status of patients. If a girl has irregular menstruation, doctors generally recommend using vaginal ultrasound or B-ultrasound for examination. The combination of the two can make the examination more clear. There are many things to note when using vaginal ultrasound and B-ultrasound, which patients need to pay attention to. Before proceeding, you need to carefully consult your doctor about relevant precautions. So, what should you do if the vaginal ultrasound is inaccurate two days before your period?

1. The difference between vaginal ultrasound and B-ultrasound

By definition:

B-ultrasound: Sound waves that vibrate 20,000 to 1 billion times per second and are inaudible to the human ear are called ultrasound. The imaging discipline that uses the physical properties of ultrasound for diagnosis and treatment is called ultrasound medicine. It has a wide range of clinical applications and has become an indispensable diagnostic method in modern clinical medicine.

Vaginal ultrasound: also known as vaginal B-ultrasound, is a method of ultrasound diagnosis in which the B-ultrasound probe is placed into the vagina or rectum. It is particularly suitable for observing pelvic organs in the small pelvis.

In terms of method:

Vaginal B-ultrasound, also known as intracavitary B-ultrasound, involves inserting a long probe into the vagina or anus to observe the pelvic organs. Compared with abdominal B-ultrasound, the images are clear and lifelike, and the patient does not need to "hold urine". Married people are examined vaginally, and unmarried people are examined anally.

Vaginal ultrasound is a method of performing B-ultrasound. The difference between it and other methods is that the probe is different and the place where the probe is placed is different.

Compared with abdominal B-ultrasound, vaginal ultrasound images are clearer and more realistic, the results are more accurate, and the person being examined does not have to "hold urine". It is particularly suitable for ovulation monitoring, diagnosis of ectopic pregnancy, uterine space-occupying diseases, and diagnosis of polycystic ovary syndrome and chocolate cysts. For those who have had sexual intercourse, a vaginal examination can be performed, and for virgins, a rectal ultrasound examination can be performed. Vaginal ultrasound is performed through the vagina and mainly looks at the pelvic cavity, which is relatively clear. B-ultrasound is in black and white and can be viewed anywhere. Generally speaking, for the same area, vaginal ultrasound is more expensive than B-ultrasound.

2. What are the indications for vaginal ultrasound examination?

1. Sonographic manifestations of the endometrium during a normal menstrual cycle and mature and immature follicles in normal ovaries.

2. Benign uterine tumors, malignant uterine tumors, non-neoplastic ovarian cysts, and ovarian tumors.

3. Abnormal early pregnancy, especially ectopic pregnancy (i.e. "ectopic pregnancy"), is a clinical emergency and may lead to death if not promptly treated.

Those who have irregular menstrual or vaginal bleeding, and those with infectious diseases such as vaginitis, sexually transmitted diseases, other cervical diseases, vaginal diseases and some vulvar diseases, to prevent infection, cross-infection and bleeding and other adverse consequences.
