Pelvimetry, used to measure pelvic size, increases the likelihood of cesarean delivery without improving perinatal outcomes. Evidence does not support its routine use in cephalic presentations.

Area of Science:

Obstetrics and Gynecology
Diagnostic Imaging

Background:

Pelvimetry evaluates maternal pelvic dimensions using clinical methods or imaging (X-ray, CT, MRI).
Assessing pelvic size is crucial for predicting potential childbirth complications.

Purpose of the Study:

To evaluate the impact of antenatal, intrapartum, or postpartum pelvimetry on delivery method.
To determine effects on perinatal mortality/morbidity and maternal morbidity.

Main Methods:

Systematic review of randomized controlled trials from the Cochrane Pregnancy and Childbirth Group trials register.
Included trials focused on pelvimetry use in cephalic presentations; quality assessment and data extraction were performed.

Main Results:

Four trials involving over 1000 women were analyzed, with generally low trial quality.

Pelvimetry use was associated with a significantly higher rate of cesarean delivery (OR 2.17, 95% CI 1.63-2.88).

No significant differences were observed in perinatal outcomes.

Conclusions:

Insufficient evidence supports the routine use of X-ray pelvimetry for women with cephalic presentations.
Current evidence does not justify pelvimetry's role in routine obstetric management for this population.
