Examination of uterine cavity represents quite frequent gynecological procedure, which may have diagnostic or therapeutic scope. The examination is realized visually with the help of thin optical systems – hysteroscopes. However, sometimes more extensive revision of uterine cavity is needed.

Most frequent indications for instrumentation are various ultrasound findings, bleeding in genital area, cervical stenosis or conditions related to the termination of pregnancy (missed abortion, incomplete spontaneous miscarriage, termination of pregnancy).

In some cases it is necessary to dilate the cervix before the instrumentation. Metal or plastic dilators are often used for such procedure. These are the sticks of various diameters which are gradually introduced in the cervix, from the thinnest to the thickest ones. The major disadvantage of this method is higher risk of cervical injury.

During an ungentle or major dilation a micro trauma may occur (especially with women who have not delivered yet or have undergone repeated dilations). This micro trauma harms the closing function of the cervix which results in dysfunctions during future pregnancies.

Osmotic dilators represent a gentle and efficient method of cervical preparation. These are thin rods made of material which absorb fluids after their insertion into the cervix, gradually increase their volume and thus open it. Most often 1-3 rods are introduced, the appropriate number is determined by the physician according to the type of surgery.

Please, ask your physician for more information.
