Diagnostic hysteroscopy is a type of gynecological examination that aims to visualize the uterus internally, in order to help in the diagnosis of possible lesions, such as polyps or uterine adhesions. Thus, this exam should be performed in the first fortnight after menstruation, as this is when the uterus is not yet preparing to receive a possible pregnancy, making it easier to observe the lesions.
This exam can be painful, but in most cases the woman only feels slight discomfort, as it is necessary to insert a thin device, known as a hysteroscope, inside the vagina.
In addition to diagnostic hysteroscopy, there is also the surgical aspect of hysteroscopy, in which the doctor uses the same method to correct changes in the uterus, which have already been diagnosed previously through diagnostic hysterectomy or other tests, such as ultrasound or ray X, for example.Learn more about surgical hysteroscopy.
What is it for
Diagnostic hysteroscopy is usually requested by the gynecologist when the woman presents any symptoms that could be a sign of some alteration in the reproductive system.
This exam may be indicated in cases of:
- Abnormal bleeding;
- Repeated abortions;
- Uterine malformation;
- Presence of polyps or fibroids;
- Uterine adhesions.
In addition, diagnostic hysteroscopy may also be indicated when there is pain during intercourse, pain in the uterus, presence of yellowish discharge or swelling in the vagina, for example, as it may be indicative of fibroids. Know the 7 main signs that the uterus may have changes.
How the exam is done
Diagnostic hysteroscopy is performed in the gynecologist's office with the woman in the gynecological position. The doctor promotes the dilatation of the uterus using carbon dioxide or a mechanical dilator, so that there is enough space to introduce, through the vaginal canal, the hysteroscope, which is a tube that emits light of about 4 mm and which has a microcamera in the tip.
Due to the presence of the microcamera, this exam can also be called diagnostic videohysteroscopy, since it allows the doctor to visualize the inside of the uterus in real time, making it possible to identify any alteration.
If the exam causes a lot of pain, the doctor may choose to perform it with sedation, in which a light anesthetic is used so that the woman does not feel the discomfort caused by the exam.
Diagnostic hysteroscopy with biopsy
When the doctor sees a change in the tissue of the uterus, he may perform a biopsy, which consists of removing a small portion of the injured tissue for analysis in the laboratory.
How to prepare
To perform diagnostic hysteroscopy, it is recommended to avoid having sexual intercourse in the 3 days prior to the exam and not to apply creams to the vagina 48 hours before the exam.
Some doctors may also recommend using a pill, such as Feldene or Buscopan, about 30 minutes before the exam to prevent the cramping and discomfort that can happen after the exam, however, this pill should only be used with medical indication.
When not to take the exam
Diagnostic hysteroscopy should not be performed during menstruation, in the presence of a vaginal infection, presence of discharge or pregnancy.
