The current gold standard for diagnosis is tomographic translabial ultrasound (TLUS) in the axial plane. Avulsion is usually described as full or partial, unilateral or bilateral. Further classification into Type I where there is a hyperechoic \u201cconnection\u201d to the sidewall, and Type II when there is no such connection has been suggested. The objective is to compare associations between avulsion types and POP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective study on archived datasets of 931 women seen at a tertiary urogynecological service.

A total of 496 (53%) reported prolapse symptoms. Overall, 741 (80%) were diagnosed with significant prolapse on POPQ, 639 (66%) on imaging. Avulsion was found in 194 (21%). An assessment of avulsion type could be undertaken in 188 women. Type I avulsions were found in 136 women (15%), Type II in 52 (6%). Type II avulsion was not found to be more predictive of symptoms and signs of POP compared to Type I avulsion (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&gt;\u2009.017 versus all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u2009.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Type II avulsion, which is supposed to represent more severe trauma, does not seem to convey any additional risk of symptoms and\/or signs of prolapse compared to Type I avulsion.
