Obstetric pessary during pregnancy

What's what for?

An obstetric discharge pessary is a mechanical device used to maintain the uterus, bladder and rectum. It is a product in the form of rings of different diameters, connected together, which makes gynecologists call it simply - a ring. It is made of an elastic biologically pure material. All edges of the ring are perfectly smoothed, so it does not injure the fabric.

The pessary enters the vagina and holds the cervix, preventing it from opening. It redistributes the load and reduces fetal pressure on the cervix. With the threat and increased risk of premature birth, the pessary helps maintain and prolong pregnancy. Such a need arises in isostico-cervical insufficiency (in particular, in the short cervix of the uterus) and in the production of several fruits that weigh heavily on the neck, speeding up its opening. Also, the ring is used to prevent the development of ICI.

Setting the pessary is an unpleasant procedure, but quick and rarely causes pain in women. However, the introduction of the ring should be pre-prepared, namely - in advance to cure all infections, if any (very often during pregnancy, escalating candidiasis). Also, that the pessary is injected with the bladder emptied.

The procedure takes several minutes: the doctor treats the ring with gel or ointment (often glycerin or clotrimazole is used for this) and inserts it into the patient's vagina. Correctly selected size helps to establish the ring as accurately and physiologically as possible. To determine the required size, you can use this table:

After the introduction

No special action is required when wearing a ring. Later, the pregnant woman will only need to take a smear for bacteriological tests every 2-3 weeks, at the same time the gynecologist will examine the condition of the cervix. But there is one nuance that can upset many future mothers and dads: after staging obstetric pessary vaginal sex is contraindicated, so that in the absence of other prohibitions, you will have to find an alternative to it.

You can retrieve the obstetric ring (as well as enter) in a hospital or outpatient setting. To do this, you should come to the gynecologist for a period of 36-38 weeks. It is extracted as quickly and simply as it is put.

Comments and Comments

Almost all women's perspective of pessaries is frightening and frustrating at first. But then it turns out that the animal is not so terrible as it is painted, and that thanks to this simple device it is really possible to reach the required time. However, not always. The obstetric ring does not give a hundred percent guarantee, and even with it the birth can happen prematurely.

Women recognize, that the pessary is almost not felt in wearing and does not cause discomfort, but here at installation and extraction nevertheless delivers not simply uncomfortable, but also painful sensations.

Practice shows that after the removal of the ring can go from one day to 3 weeks, before you give birth, - here everything is individual. Therefore, it is removed, as a rule, no later than 38 weeks.


Pessary obstetrics is often the only correct solution for the threat of premature birth. However, unfortunately, you can not put it to all women. So, among the contraindications - conditions and diseases, in which prolonging pregnancy can be dangerous. You can not put the ring, if in the second and third trimesters a woman had repeated bloody discharge.

In addition, in a number of cases, pessaries need to be removed early: with the release of amniotic fluid, in the case of the need for emergency delivery, with the development of chorioamnionitis.

In the process of wearing a pessary can move slightly, and the development of a mechanical colpite is possible, as evidenced by the appearance of whitecaps. The situation is easily correctable with gynecological examination.

If the woman's uterus has increased sensitivity and excitability, in order to prevent its contractions, it is necessary to take an antispasmodic 30-40 minutes before the introduction or extraction of the pessary.

Of course, the obstetric ring can not be used again - it is one-time.
