However, physical examination of such women often reveals pelvic floor laxity, even in a relaxed state. Therefore, we aimed to verify the hypothesis that sagging of the pelvic floor can be detected on resting-state magnetic resonance images in the supine position.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We retrospectively evaluated resting-state magnetic resonance imaging findings in women with (<i>n</i> = 193; all underwent surgical treatment) and without (controls; <i>n</i> = 193) pelvic organ prolapse who had at least one prior vaginal delivery. We compared the lengths of the pubococcygeal line, H-line, and M-line between the groups.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The median lengths (interquartile ranges) for the prolapse and control groups were 98.3 (91.9–104.0) and 95.1 (90.3–101.4) mm (<i>p</i> = 0.0011), respectively, for the pubococcygeal line; 61.5 (56.0–67.9) and 51.1 (47.2–55.6) mm (<i>p</i> &lt; 0.0001), respectively, for the H-line; and 24.6 (20.4–29.0) and 8.6 (3.9–13.0) mm (<i>p</i> &lt; 0.0001), respectively, for the M-line. Similarly, in the multiple regression analysis adjusted for age, height, body mass index, a history of operative vaginal delivery, and a history of hysterectomy, the pubococcygeal line, H-line, and M-line were significantly longer in the prolapse group.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>In women with pelvic organ prolapse, the H-line and M-line are significantly longer on resting-state magnetic resonance images, allowing for the detection of pelvic floor relaxation.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16593,"journal":{"name":"Journal of Obstetrics and Gynaecology Research","volume":"51 2","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
