What can vaginal ultrasound detect?

The full name of vaginal ultrasound is vaginal B-ultrasound examination, which is very common in daily life. This examination is helpful for ovulation monitoring, diagnosis of ectopic pregnancy, and can also detect benign uterine tumors, malignant uterine tumors, ovarian non-neoplastic cysts, ovarian tumors and other diseases, which helps doctors to judge the condition. It is usually performed after a routine gynecological examination. Friends in need can go to the hospital to seek the doctor's advice.

1. Transvaginal ultrasound

Vaginal ultrasound is the abbreviation of vaginal B-ultrasound, also known as intracavitary B-ultrasound. It is a method of ultrasonic diagnosis by inserting the B-ultrasound probe into the vagina or rectum. It is particularly suitable for observing pelvic organs in the small pelvis. 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".

Vaginal ultrasound 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.

2. Indications

1. Sonographic manifestations of the endometrium during a normal menstrual cycle and the mature and immature follicles in normal ovaries (the so-called "ovulation detection").

2. Benign uterine tumors: 1. Adenomyosis; 2. Uterine fibroids.

3. Uterine malignancies: 1. Endometrial cancer; 2. Cervical cancer.

4. Non-neoplastic ovarian cysts: 1. Polycystic ovary syndrome; 2. Chocolate cyst.

5. Ovarian tumor.

6. Make a clear diagnosis of early pregnancy as early as possible.

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

(III) Inspection methods

1. It is usually performed after a routine gynecological examination.

2. Ask the patient to urinate and take the lithotomy position.

3. Cover the vaginal probe with a disposable condom and apply disinfectant coupling agent inside and outside the condom.

4. The operator wears gloves, holds the probe handle with his right hand, and slowly inserts the probe into the vaginal vault.

5. Tilt, push, pull, and rotate the probe handle during operation to observe the entire pelvic structure.

6. The patient needs to lie flat on the bed, relax the body and don't be nervous. Excessive nervousness will affect the examination results.

4. Advantages of transvaginal ultrasound

Vaginal probe has certain advantages over abdominal exploration:

① It has high sensitivity and display rate to uterine artery and ovarian blood flow.

② Shorten the inspection time and obtain accurate Doppler spectrum.

③ No need to fill the bladder.

④ Not affected by body type obesity, abdominal scars, intestinal gas distension, etc.

⑤ Use the movement of the probe tip to find the tenderness of the pelvic organs to determine whether there is pelvic adhesion.
