The Effect of Aging on Pelvic Floor Pressure Measurements in Nulliparous Women

摘要

Aims: To investigate the correlation between age and 3-dimensional pelvic floor manometry parameters, sexual function, and urinary status in old post-menopausal versus young nulliparous women. Methods: This was a cross-sectional study. Two groups of young (18 - 40 years) and old (52 - 85 years) nulliparous volunteers completed Pelvic Floor Distress Inventory (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), and Female Sexual Function Inventory (FSFI-19) and underwent a 3-dimensional pelvic floor manometry. Results: The study included 9 young participants with a mean age of 28.6, and 10 old participants with a mean age of 61.8. All the older participants were postmenopausal and all the young participants were premenopausal. Mean PFDI-20 score was significantly higher in the older group: 52 ± 12 versus 4 ± 4, p= 0.001. Urinary Distress Inventory score (UDI-6, part of PFDI questionnaire) was higher amongst the older group: 28 ± 26 versus 3 ± 8, p= 0.006. All young participants scored zero in their PFIQ-7 while the older participants averaged 31 out of maximal score of 300. While sexual activity was higher in the younger group (89% versus 60%), sexual function assessed through the FSFI-19, was not significantly different between the two groups. Valsalva pressures obtained from manometry measurements were significantly higher in the older group (mean 230 mm Hg versus 161, p= 0.015). Conclusions: Post-menopausal women have higher pelvic floor and urinary symptoms associated with increased Valsalva pressures as measured by vaginal manometry.
