  • Pelvic dimension as a predictor of ureteral injury in gynecological cancer surgeries. [Journal Article]
    Surg Endosc. 2020 09; 34(9):3920-3926.Ye H, You D, … Xi M
  • CONCLUSIONS: This study demonstrated that mid-pelvis dimensions were associated with ureteral injury, but the observed differences were too small. In addition, pelvic inlet dimensions did not appear to relate with ureteral injury. Thus, these pelvimetry measures could not be beneficial in assessing the risk of ureteral injury in gynecological cancer surgeries.
  • StatPearls: Anatomy, Abdomen and Pelvis, Pelvic Inlet [BOOK]
    StatPearls. StatPearls Publishing: Treasure Island (FL) Siccardi Marco A. MA San Paolo Hospital Savona Imonugo Onyebuchi O Medical College of Georgia at Augusta University Valle Cristina C S Paolo Hospital, Savona BOOK
  • The pelvic inlet, or the upper pelvic narrow, is the anatomical limit between the true pelvis below and the false pelvis above. There are tangible, genetic, and hormonal differences between the male and female pelvis related to reproductive function. In obstetrics, the pelvic inlet is the entrance door toward the birth canal. The fetal cephalic extremity needs to position itself and adapt adequat…
  • Which Foetal-Pelvic Variables Are Useful for Predicting Caesarean Section and Instrumental Assistance? [Journal Article]
    Med Princ Pract. 2017; 26(4):359-367.Frémondière P, Thollon L, … Marchal F
  • CONCLUSIONS: The antero-posterior inlet was an efficient variable unlike the obstetric conjugate. The obstetric conjugate diameter should no longer be considered a useful variable in estimating the arrest of labour. Antero-posterior inlet diameter was a sagittal variable that should be taken into account. The comparison of sub-pubic angle and bi-parietal and antero-posterior outlet diameters was useful in identifying a risk of requiring instrumental assistance.
  • Pelvimetry by Three-Dimensional Computed Tomography in Non-Pregnant Multiparous Women Who Delivered Vaginally. [Journal Article]
    Pol J Radiol. 2016; 81:219-27.Salk I, Cetin A, … Cetin M
  • CONCLUSIONS: The findings of this study present the reference values of the main planes of the true pelvis by 3D CT pelvimetry in a relatively large group of multiparous women who passed a trial of labor successfully. Overall, the pelvises had features of female pelvic bony structure although pelvic diameters were somewhat lower in multiparous women with short stature. The 3D pelvimetry with CT applications may be used as an adjunct to clinical and ultrasonographic examinations to rule out cephalopelvic dystocia in selected cases.
  • Persistent occiput posterior. [Journal Article]
    Obstet Gynecol. 2015 Mar; 125(3):695-709.Barth WH
  • Persistent occiput posterior (OP) is associated with increased rates of maternal and newborn morbidity. Its diagnosis by physical examination is challenging but is improved with bedside ultrasonography. Occiput posterior discovered in the active phase or early second stage of labor usually resolves spontaneously. When it does not, prophylactic manual rotation may decrease persistent OP and its as…
  • [Anthropometric analysis of obstetrical pelvis from Neolithic area: obstetrical consequences. Preliminary study]. [Journal Article]
    Gynecol Obstet Fertil. 2011 Nov; 39(11):614-9.Raia-Barjat T, Tardieu AS, … Chêne G
  • CONCLUSIONS: Reconstructions based on Neolithic hominin fossils suggest that obstetrical mechanisms were probably common to Neolithic and modern humans: childbirth would probably require social adaptations and risks of perinatal and obstetric complications were undoubtedly high. However, the differences in morphometric analysis could suggest a change of human pelvis and raise the question of the evolution in obstetrical mechanisms in the future.
  • Severe shoulder dystocia with a small-for-gestationaI-age infant: a case report. [Case Reports]
    J Reprod Med. 2011 Mar-Apr; 56(3-4):178-80.Ruis KA, Allen RH, Gurewitsch ED
  • CONCLUSIONS: Geometric analysis reveals that borderline adequate pelvimetry likely played a significant role in severe shoulder dystocia etiology, even with a small-for-gestational-age infant. We alert obstetric providers to the possibility of severe shoulder dystocia in patients with borderline adequate pelves on clinical examination, even when estimated fetal weight makes cephalopelvic disproportion unlikely.
  • Three-dimensional pelvimetry by computed tomography. [Journal Article]
    Radiol Med. 2009 Aug; 114(5):827-34.Lenhard M, Johnson T, … Hasbargen U
  • CONCLUSIONS: Pelvimetry can be obtained with low interobserver variability on 3D volume-rendered CT reconstructions. Thus, CT pelvimetry is suitable to gain exact knowledge of pelvic anatomy to identify relevant parameters for dystocia in retrospective studies.
  • Racial differences in pelvic anatomy by magnetic resonance imaging. [Journal Article]
    Obstet Gynecol. 2008 Apr; 111(4):914-20.Handa VL, Lockhart ME, … Pelvic Floor Disorders Network
  • CONCLUSIONS: White women have a wider pelvic inlet, wider outlet, and shallower anteroposterior outlet than African-American women. In addition, after vaginal delivery, white women demonstrate less pelvic floor mobility. These differences may contribute to observed racial differences in obstetric outcomes and to the development of pelvic floor disorders.
  • Costal process of the first sacral vertebra: sexual dimorphism and obstetrical adaptation. [Journal Article]
    Am J Phys Anthropol. 2007 Mar; 132(3):395-405.Tague RG
  • The human sacrum is sexually dimorphic, with males being larger than females in most dimensions. Previous studies, though, suggest that females may have a longer costal process of the first sacral vertebra (S1) than males. However, these studies neither quantified nor tested statistically the costal process of S1. This study compares S1 with the five lumbar vertebrae (L1 to L5) for a number of me…
  • The anterior dimensions of the pelvis in male and female Nigerians. [Journal Article]
    Afr J Med Med Sci. 1995 Dec; 24(4):329-35.Nwoha PU
  • A retrospective study on the anteroposterior X-ray films of the pelvis of 40 male, and 31 female Nigerians was undertaken to verify if there was any significant difference in the values of the transverse diameter of the inlet (TID), bicristal diameter (BCD), bituberal diameter (BTD), and subpubic angle (SA) between the male and the female, between the younger age group (21-45 years) and the older…
  • The prognostic value of magnetic resonance imaging for the management of breech delivery. [Journal Article]
    Eur J Obstet Gynecol Reprod Biol. 1994 Jun 15; 55(2):97-103.Berger R, Sawodny E, … Künzel W
  • In patients with breech presentation secondary cesarean section is often caused by a failure to progress in labor due to a disproportion between fetal breech and maternal pelvis. The aim of the present study was to select such patients for primary cesarean section by prenatal use of magnetic resonance imaging. In 39 patients with breech presentation at term, maternal obstetric conjugate, transver…
