[Impact of the aged-related changes of sagittal spinal curvature on pelvic organ prolapse. A systematic review of the literature]. / Impact des modifications des courbures vertébrales sagittales liées à l'âge sur les prolapsus des organes pelviens. Une revue systématique de la littérature.

OBJECTIVES: The aim of this review was to specify the potential association between age-related changes in sagittal spinal curvature and risk of pelvic organ prolapse in women. METHODS: A systematic review based on the PRISMA statement was performed. Keywords were chosen according to the eligibility criteria in line with the PICO model. For inclusion, studies had to be based on observational cohorts, case controls and cross sectional studies. The quality of the articles was assessed using the STROBE scale. RESULTS: Five papers from 1996 to 2021 were included in the present review with conflicting results. Four studies reported a positive association between anatomical pelvic organ prolapse at clinical examination, a loss of lumbar lordosis and an increase in thoracic kyphosis. The remaining study, using a questionnaire-based assessment of symptoms, found no association between prolapse-related symptoms and age-related changes in sagittal spinal curvatures. CONCLUSION: Based on the available evidence, this systematic review suggested a very moderate evidence of association between the development of anatomical pelvic organ prolapse and age-related changes in sagittal spinal curvature in women. This review remains very limited by the small number and the heterogeneity of the studies included. Further studies in the lifetime continunm, with high quality methodology are needed to better understand the physiopathology of pelvic organ prolapse.
