Assessment of the shape and dimensions of a woman’s pelvis by making measurements on an X-ray image. Pelvimetry may be carried out to determine whether a woman is likely to have difficulty in delivering a baby vaginally. The procedure may also be performed after a vaginal delivery has been unsuccessful, to assist in planning a future pregnancy.
Measurement of the internal dimensions of the PELVIS. The four diameters measured are: transverse, anterioposterior, and left and right oblique. These measurements help to establish whether a fetus can be delivered normally. If the outlet is abnormally small, the mother will have to be delivered by CAESAREAN SECTION.
n. measurement of the four internal diameters of the pelvis (transverse, anteroposterior, left oblique, and right oblique) on an X-ray image or by means of CT or MR scanning. Pelvimetry may be used to determine if a vaginal delivery will be possible, but it is an unreliable predictor of obstetric outcome and its use is outmoded. Clinical pelvimetry is a means of assessing pelvic capacity through a vaginal examination; it is subjective and its results must be used with caution.
