Introduction and hypothesis
To compare the impact of vaginal delivery (VD) versus cesarean section (CS) on the pelvic floor in twin primiparae at 3 and 12 months postpartum.
Methods
This comparative multicenter prospective cohort from a large French national cohort study consisted of primiparas who gave birth to live twins after 34 weeks of gestation. The primary end point was the postnatal urinary incontinence rate 3 months postpartum. The secondary end points were the pelvic floor dysfunction (PFD) at 3 and 12 months based on PFDI-20, PFIQ-7, PISQ-12, and SF-12 responses.
Results
A total of 2812 patients in 172 French maternity units were recruited between February 2014 and March 2015: 1076 (38%) responded at 3 and 12 months (61% at 3 months); 1155 were analyzed at 3 months (556 VD and 599 CS) and 800 at 12 months (394 VD and 406 CS). VD was associated with more symptoms at 3 months [median PFDI-20 score 25/300 (8–50) vs. 17/300 (4–36) after CS; p < 0.0001]. Vaginal bulge was more frequently reported after VD (9 vs. 4%; p = 0.0015). Abdnormal PFD-related quality-of-life scores (scores > 0) were more frequent after VD at 3 months (58 vs. 42%; p < 0.0001) and 12 months (57 vs. 43%; p = 0.0020), indicating greater discomfort. However, SF-12 scores were higher after VD [56 (53–59) vs. 55 (51–58)] at 12 months, indicating better general quality of life.
Conclusions
Mode of delivery is significantly associated with pelvic organ prolapse symptoms 3 months postpartum, which regress by 12 months, probably because of the known spontaneous postnatal improvement of PFDs.
