Introduction: Good obstetric management is based on the knowledge of the normal parameters of population and this is particularly true regarding the pelvis and labor. There is little information in the literature describing the normal values of the pelvis among Mongolian women.
Materials and Methods: Two hundred ninety four reproductive age- Mongolian women were recruited to estimate normal pelvic parameters and the principal diameters were measured by computed tomography (CT) and the clinical pelvimetries. Significance was determined by computerized unpaired t-test and ascribed to P values <0.05.
Results: External pelvic dimensions measured by CT was 25.82 for d.sp, 28.04 for d.cr, 29.15 for d.tr and 19.63 for c.ext. Comparison of four dimensions of false pelvis showed that c.ext was increased according to age or had difference with statistical significance (p=0.01) for age groups and Ho=Ho hupothesis of our study was confirmed . D.cr d.tr and d.sp were similar for age groups and had difference without statistical significance, thus average of these dimensions can be used as a reference.
Conclusion: In the current study we estimated the normal values of external and internal pelvic parameters among reporoductive age women. The results of this study reveal that the CT pelvimetry has more precise results than the clinical pelvimetry particularly for internal pelvic measurements.
