Pelvic Organ Prolapse (POP) is the protusion of pelvic viscera through the pelvic floor and vaginal walls – responsible for the sensation of “ball in the vagina”, as well as the presence of symptoms such as urinary and fecal incontinence, bleeding, discharge and vaginal infections. As it directly affects women’s quality of life, its genesis has been studied and has presented several branches of causality: advanced age, menopause, previous hysterectomy and, for some, altered bone diameters

Objective: To investigate the role played by the bone dimensions of the pelvis in relation to the genesis of pelvic organ prolapses through publications from the last fifteen years.

Methods: This is a systematic review of observational studies for risk assessment and prognosis through a virtual bibliographic survey of scientific articles published in digital journals, in PubMed, BVS and ScienceDirect databases.

Results: A wider anterior pelvic area and a larger interspinous diameter were characterized as possible causes for pelvic organ prolapses. Most of the studies have diversified bone measurements, in which the other dimensions weren’t statistically significant.

Conclusion: The studies evaluated in this review suggest a new measurement of the pelvic floor related to women with prolapse, with a larger anterior area, largely influenced by the interspinous diameter, which leads to an increased load on the pelvic floor. However, even so, there is an urgent need for further studies to corroborate our findings.
