Abstract
Comparative estimation of magnetic-resonance pelvimetry and external pelvimetry measurements in 182 pregnant women at the end of the III trimester was performed. Basing of the magnetic-resonance pelvimetry data frequency and structure of a narrow pelvis were defined, and radiological classification of the narrowed forms of pelvis was analysed and added. According to magnetic-resonance pelvimetry data the narrowed pelvis was revealed in 158 (86,7%) women and «latent» form of narrowed pelvis (I and II degree) with reduction of several of 8 sizes of midpelvis lesser than on 1–2 cm from normal was determined in 125 (68,8%). T rue narrow pelvis (narrowing of the pelvis distances more than on 2 cm from normal) was developed in 33 (18,1%) women. The normal pelvis was found in 10,3% women. When the narrowing of midpelvis distances did not exceed 1 cm from normal (n=61), only in 26,1% women some changes from the external sizes were found. When the narrowing of midpelvis distances did not exceed 2 cm from normal (n=64), the external sizes were changed only in 51,5%. The general detection of anatomically narrowed pelvis with external pelvimetry was 77,3%, normal — 60%, latent» form of narrowed pelvis — 30,7%.
