Pelvimetry: measurement of the internal diameters of the pelvis

Pelvimetry is a medical procedure that is used to measure the four internal diameters of the pelvis: transverse, anteroposterior, left diagonal and right diagonal. The purpose of pelvimetry is to determine whether the fetus is able to pass through the mother's birth canal during labor.

Doctors use pelvimetry to assess pelvic size in women who are at risk for difficulty giving birth due to a narrow pelvis or other abnormalities related to pelvic size. Pelvimetry can be performed both during pregnancy and during childbirth if problems arise with the passage of the fetus through the birth canal.

Transverse diameter is measured between two lateral points of the pelvis, anteroposterior diameter is measured between the anterior and posterior edges of the pelvis, and diagonal diameters are measured between points on the anterior and posterior walls of the pelvis. The normal values ​​for these diameters vary depending on the woman’s constitution and her height.

If one or more pelvic diameters are reduced compared to normal, this can lead to difficulties in the passage of the fetus through the mother's birth canal. In such cases, doctors may recommend a cesarean section to avoid complications and ensure the safety of both mother and baby.

Pelvimetry is a safe procedure that can help doctors decide which birth method will be safest and most effective for a particular woman. If you have any questions or concerns about pelvimetry, contact your doctor for more information.

Pelvimetry.

Pelvimetry is the measurement of the four internal diameters of the pelvis: transverse, anteroposterior, left and right diagonal. This is an important diagnostic method that allows you to determine whether the fetus will be able to pass through the mother's birth canal during labor. If one or more pelvic diameters are smaller than normal, a caesarean section may be necessary.

To carry out pelvimetry, a special device is used - a pelvigraph, which measures the size of the pelvis in different projections. The doctor takes measurements carefully so as not to damage the fetus or cause discomfort. The results of pelvimetry help determine what dimensions of the pelvis need to be changed to ensure normal passage of the fetus through the birth canal.

In some cases, pelvimetry can be performed even before pregnancy, which helps to identify possible problems and take measures to eliminate them. For example, if a woman has already had a difficult birth, her doctor may recommend that she undergo pelvimetry to determine the size of her pelvis and decide how best to prepare for the next pregnancy.

It is important to note that pelvimetry is not the only method for diagnosing and determining the size of the pelvis. It can be supplemented by other methods, such as ultrasound, CT and MRI, which provide more accurate information about the condition of the pelvis and its size. However, pelvimetry remains an important diagnostic method that helps determine how safe childbirth will be and what measures can be taken to ensure its success.

Theory and methodology of pelvimetry

Pelvimetry is one of the pelvic examination methods that is used to determine the shape, size and abnormalities of the bones of the pelvic cavity. In the process of pelvimetry, four main parameters of the shape and size of the pelvis are measured: transverse, anteroposterior, left and right diagonal dimensions. When this examination is necessary, the doctor asks the woman to undress. The patient must take a certain body position to give it the most correct appearance. In this position, the woman spends quite a long time with the gynecologist. The results of pelvimetry show the doctor how the delivery is going and how safe it is. The pelvimetry method helps the specialist select the optimal delivery option for a particular woman in labor. If they decrease from normal size, it may be necessary to perform a caesarean section. Also, the results of pelvimetry may indicate a narrow pelvis, when it does not allow the mother’s birth canal to pass the newborn through it. In such a situation, the doctor determines the method of delivery, namely cesarean section or natural birth. Currently, the pelvimetry method is considered one of the most accurate methods for determining the size of the pelvis and choosing the optimal method of delivery. Before this method appeared
