During ultrasound pelvic organs is carried out a number of measurements and the study of their structural features. The uterus, cervix and ovaries must meet certain parameters. Dimensions of ultrasound of the uterus should be normal both in parous and nulliparous women, and has its own standards for each age cohort. Resizing an ultrasound can mean a variety of abnormalities, which requires a more detailed diagnosis.

Standards length, width, thickness and volume to US - volatile indicators. They depend on a number of conditions:

  • age;
  • growth;
  • weight;
  • body;
  • presence and number of children;
  • by a history of missed abortion, miscarriage or abortion;
  • an illness and operations.

During ultrasound compulsorily spend measurement of longitudinal, lateral and anterior-posterior uterine measurements, calculate the volume, as well as measure the cervix of women. If the figures on the length or shape of the abnormal, it does not necessarily indicate a serious disease, but requires special attention doctors and further regular monitoring.

The ideal parameters for an ultrasound of the neck are equal to about 1/3 of the size of the uterine body. It increases and decreases along with the uterus, depending on the patient's age, health, and the number of pregnancies carried over.

If a woman has not given birth, uterine size at ultrasound are normal:

  • length - 4.4 +/- 0.6 cm
  • width - 4.3 +/- 0.6 cm
  • thickness - 3.2 +/- 0.5 cm.

If a woman has had an abortion, or scraping by prescription, it will inevitably lead to some increase in enforcement. A few millimeters will increase standards for all parameters:

  • length - 4.9 +/- 0.6 cm
  • width - 4.6 +/- 0.5 cm
  • thickness - 3.7 +/- 0.5 cm.

After each delivery the uterus is a little stretched, but after the third child is stretching will be minimal. The norm for an ultrasound for women after the birth of two more children:

  • longitudinal dimension - 5.6 +/- 0.9 cm
  • transverse dimension - 5.5 +/- 0.5 cm
  • anteroposterior size - 4.3 +/- 0.6 cm.

The menopause and after uterine volume becomes smaller. This is due to a decrease in the number of female sex hormones. The smallest body parameters and the cervix was observed after 5-6 years after the onset of menopause. The norm for this period in the US: 2,8-3,8 x 2-3 x 2,6-3,6 cm.

Why change indicators

Changing the length, thickness and width throughout a woman's life are primarily related to the reproductive functions. Initially the girls are born with a sufficiently "advanced" uterus. Its length is about four centimeters. By the year there is an involution of the body - it is reduced by about half, and in this state for up to seven years. With seven years to the end of puberty, it gradually increases and becomes normal parameters.

Further changes will be associated with pregnancy. At this time, the uterus is strongly stretched and reaches a length of 38-40 centimeters. After delivery, she was again reduced and becomes normal size, however, a small increase in its relative doberemennogo condition is still present.

Climax - the next stage of the natural changes in the genitals. Hormones progesterone and estrogen produced by the female body at a young age, are no longer produced in the right quantities, reproductive function fades and organs normally "dry out."

Diseases that cause changes in the size of the uterus on ultrasound

If uterine ultrasound revealed changes when measuring - it is a reason to assume the presence of a pathological process. Increasing the cause:

  • fibroids - benign growths in the uterus;
  • cyst - pathological cavities in the body tissues;
  • cancers;
  • adenomyosis (internal endometriosis);
  • serozometra;
  • polyps;
  • endometrial hyperplasia.

Symptoms that increased size of the uterus:

  • abdominal pain;
  • urinary incontinence;
  • menstrual disorders, increased blood loss during the critical days.

Treating enlarged poppies appointed in accordance with the violation found. Resorted to as medication therapies (antibiotics, COC means enhancing immunity) and to surgical (removal of fibroids, cysts, polyps).

When the detected deviation of sizes of below normal ultrasound, the diagnosis is a small womb. There are three stages of deviations from the norms in this diagnosis:

  • hypoplasia - the uterus corresponds to the size of the body of a teenager;
  • infantilism - the womb as a baby;
  • aplasia - hypoplasia expressed.

The symptoms of an underdeveloped uterus:

  • late onset of menstruation or their absence;
  • delayed puberty;
  • underdevelopment "female pattern": a narrow pelvis and thorax, the lack of growth of the mammary glands;
  • libido problems;
  • irregular cycle or absence of menstruation;
  • problems with conception.

The problem with this disease is that the reproductive organs during puberty is not developing as it should and is likely to become pregnant, will have to make a lot of effort.

Thanks to modern hormone replacement therapy often fails to "grow" a defective body to the required size and successfully conceive and bear a child without surgical intervention. The only exception is aplasia of the uterus, a pregnancy at such pathology is only possible after in vitro fertilization procedure (IVF) using the services of a surrogate mother.

The dimensions of the uterus during pregnancy

The most common reason for a pleasant and increase the size of the uterus is an ultrasound pregnancy. From the moment of its occurrence, and to the birth it will grow with your baby. The main size can be considered as the length of this period. It was her beginning in the second trimester, or even a little earlier, should be measured at each visit a gynecologist. Up to this point the size of the uterus matching deadline checked by manual examination of the woman or using vaginal ultrasound probe.

According to the size of the uterus the doctor will determine the duration of pregnancy, to monitor the proper growth of the fetus and can even assume the presence of abnormalities during pregnancy. Size, which determines the physician via palpation of the abdomen and is called a centimeter height of the bottom. Starting with 12-14 weeks of its size will be equal to the term of pregnancy and every week will increase by an average of one centimeter, reaching to the time of delivery of the level of 38-40 centimeters.

Minor deviations from the norm in the amount of the main female body does not always mean a serious pathology. The body of every woman is different, so, provided good performance over all other criteria on Ultrasound, most likely, the doctor recommended to be screened once a year to monitor the state health.
