Pelvic floor symptoms from first pregnancy up to 8 years after the first delivery: a longitudinal study.

BACKGROUND: Despite the strong association between vaginal childbirth and pelvic floor dysfunction, genetic factors, pregnancy, advancing age, and lifestyle also play a role. The pelvic floor undergoes substantial changes during pregnancy, which may contribute to pelvic floor dysfunction. Conversely, these changes may be favorable for vaginal delivery. However, there is a lack of studies assessing pelvic floor symptoms over time according to delivery mode and including predelivery assessment. OBJECTIVE: This study aimed to describe urinary incontinence, vaginal symptoms, and bowel control symptoms from 21 weeks of gestation in the first pregnancy up to 8 years after the first delivery, stratified by delivery mode. STUDY DESIGN: This was a longitudinal observational cohort study. A total of 300 nulliparous women were recruited during their first pregnancy. Pelvic floor symptoms were assessed at 21 and 37 weeks of gestation, and at 6 weeks, 6 months, 12 months, and 8 years after first delivery using the International Consultation on Incontinence Questionnaire modules: the urinary incontinence sum score, the weighted vaginal symptom sum score, the vaginal-associated quality of life score, the bowel control sum score, and the bowel-associated quality of life sum score. Delivery mode at first delivery defined delivery groups as: normal vaginal, operative vaginal, and cesarean delivery. A linear mixed-model analysis was used to assess symptom scores over time and differences in symptom scores between the delivery groups. RESULTS: Of the 300 women included in the study, 193 attended the 8-year follow-up. Pelvic floor symptoms differed between women who had vaginal delivery and those who had cesarean delivery. The symptom scores showed a nonlinear statistically significant trend. In women who delivered vaginally, there was an increase of urinary incontinence and vaginal symptom scores already during pregnancy. In women who later delivered by cesarean, there was a decrease of symptom scores during pregnancy, and overall lower symptom scores relative to women who had vaginal delivery at 12 months after the first delivery. Pelvic floor symptom scores increased from 12 months to 8 years after the first delivery and exceeded pregnancy levels in all delivery groups; however, overall symptom scores were low. Differences between delivery groups were not statistically significant. CONCLUSION: Pelvic floor symptoms differed between women who had vaginal delivery and those who had cesarean delivery from the first pregnancy up to 8 years after the first delivery. These differences were already recognizable before the first delivery.

Risk factors for anatomic pelvic organ prolapse at 6 weeks postpartum: a prospective observational study.

INTRODUCTION AND HYPOTHESIS: The objective was to identify risk factors for postpartum anatomic pelvic organ prolapse (aPOP) by comparing women with and without aPOP at 6 weeks postpartum with regard to pelvic floor measurements antepartum and obstetrical characteristics. METHODS: We carried out a prospective observational cohort study including nulliparous pregnant women in a Norwegian university hospital. Participants underwent clinical examinations, including pelvic organ prolapse quantification system (POP-Q) and transperineal ultrasound at gestational week 21 and at 6 weeks postpartum. Background and obstetrical information was obtained from an electronic questionnaire and from the patient's electronic medical file respectively. Associations were estimated using logistic regression analyses. The dependent variable was aPOP, defined as POP-Q stage ≥2 at 6 weeks postpartum. Independent variables were mid-pregnancy measurements of selected POP-Q variables and levator hiatus area (LHarea), delivery route, and the presence of major levator ani muscle (LAM) injuries at 6 weeks postpartum. RESULTS: A larger LHarea, a more distensible LAM, a longer distance from the meatus urethra to the anus (Gh + Pb) and a more caudal position of the anterior vaginal wall (Ba) at mid-pregnancy were risk factors for aPOP at 6 weeks postpartum, whereas delivery route and the presence of major LAM injuries were not. CONCLUSION: Prelabor differences in the pelvic floor rather than obstetrical events were risk factors for aPOP at 6 weeks postpartum.

Association between vaginal bulge and anatomical pelvic organ prolapse during pregnancy and postpartum: an observational study.

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is defined as the coexistence of anatomical POP and relevant symptoms. Vaginal bulge is the symptom most closely associated with the anatomical condition in nonpregnant women. Even if childbearing is a major risk factor for the development of POP, there is scant knowledge on the prevalence of specific POP symptoms, and how these symptoms relate to anatomical POP during pregnancy and postpartum. The aim of this study was to explore whether vaginal bulge symptoms were associated with anatomical POP in pregnancy and postpartum, and to present the prevalence of vaginal bulge symptoms throughout this period. METHODS: A prospective observational study was carried out following 300 nulliparous pregnant women with repeat assessments from mid-pregnancy until 1 year postpartum. Symptoms of vaginal bulge defined as the sensation of a vaginal bulge inside and/or outside the vagina were assessed by electronic questionnaires. Anatomical POP defined as pelvic organ prolapse quantification system (POP-Q) stage ≥2 has been presented in a previous publication and showed a range of 1-9%. The association between the symptom vaginal bulge and anatomical POP at the various visits was analyzed using Fisher's exact test. RESULTS: Prevalence of vaginal bulge ranged between 16 and 23%. At 6 weeks postpartum the symptom was associated with anatomical POP; otherwise, these two features were unrelated. CONCLUSIONS: The symptom vaginal bulge was barely associated with anatomical POP, and cannot identify anatomical POP in pregnancy or postpartum.
