En cherchant sur le web anglophone à l'aide du moteur www.google.com, j'ai trouvé quelques références de pages sur l'utilité de la pelvimétrie.

D'abord, un article datant de 1998 :

VALUE OF COMPUTED TOMOGRAPHY PELVIMETRY in PATIENTS WITH A PREVIOUS CESAREAN SECTION
Evaluation de la pelvimétrie tomographique pour des patientes ayant subi une césarienne

http://www.kfshrc.edu.sa/annals/181/97-119.html

C'est un test sur 219 patientes dans un hôpital d'Arabie Saoudite.

L'article conclut à l'inutilité de cette procédure pour des femmes devant accoucher après avoir subi une césarienne. Inutilité et nocivité puisqu'elle provoque des césariennes inutiles, avec toutes les conséquences connues.

Détails :

There were no significant differences in maternal characteristics between the women who had antenatal CT pelvimetry and those who did not (Table 1). We found a statistically significant difference in the rate of cesarean section in the two groups (P=0.02). Fifty-one women (51%) in the CT pelvimetry group delivered by cesarean section. Twenty-three women (23%) underwent elective cesarean section for contracted pelvis based upon the findings of CT pelvimetry, and 28 women (28%) underwent emergency cesarean section after trial of labor. In the group who did not have CT pelvimetry, 26 women (21.8%) underwent emergency cesarean section. Likewise, vaginal delivery occurred in 49 out of 100 women (49%) who had CT pelvimetry, compared to 93 of 119 women (78.2%) in the control group (P=0.02).

Six women (6%) in the pelvimetry group and three (2.5%) in the control group underwent induction of labor with prostaglandins (prostin 2.5 mg intravaginal suppository). The small number of patients excludes any purposeful comparison. Interestingly, the duration of labor in those who delivered vaginally was shorter in the pelvimetry group (5.7 hours ± 4.6) when compared to the control group (7.5 hours ± 4.9) (P=0.01). There were no significant differences between the groups in the mean birthweight and Apgar scores. There was no perinatal or maternal mortality in this series. Women who delivered vaginally in the CT pelvimetry group and control group were discharged home earlier than those who underwent cesarean section.
