Abstract

Objective: Our purpose was to compare pelvic organ support in nulliparous pregnant and nonpregnant women at a single institution.

Study design: This was a case-control study. Pregnant patients and nonpregnant control subjects were matched according to age and race. Subjects underwent pelvic organ support evaluation by use of the pelvic organ prolapse quantification (POPQ) examination as part of routine prenatal or gynecologic care. The Pearson chi(2) statistic was used for statistical analysis, with a P value of 5% set for significance.

Results: A total of 21 pregnant and 21 nonpregnant nulliparous women between the ages of 18 and 29 years were included. All patients in the nonpregnant group had a POPQ stage of 0 or 1, whereas 47.6% of the pregnant subjects had POPQ stage 2 (P <.001). Individual components of the POPQ examination were compared. Significant differences were noted for points Aa and Ba, Ap and Bp, and PB and TVL.

Conclusions: In nulliparous women, pregnancy is associated with increased POPQ stage compared with nonpregnant control subjects.
