Independent risk factors for postpartum stress urinary incontinence were identified using multivariate logistic regression analysis. A nomogram model was constructed using R 4.3.1 software and the rms package to evaluate the correlation between the identified factors and the disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Maximal Valsalva state posterior urethrovesical angle (RVA), bladder neck descent, and Young\u2019s modulus of the resting posterior lip of the urethral sphincter were identified as independent risk factors for postpartum stress urinary incontinence (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.05). The areas under the receiver operating characteristic curve for RVA, bladder neck descent, and posterior lip of the urethral sphincter were 0.840, 0.867, and 0.914, respectively, indicating high diagnostic efficiency. The nomogram model demonstrated that the risk of developing stress urinary incontinence increased with higher RVA and bladder neck descent values and lower posterior lip of the urethral sphincter values, with posterior lip of the urethral sphincter showing the strongest correlation with the disease.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>RVA (Valsalva), bladder neck descent, and posterior lip of the urethral sphincter are independent risk factors for postpartum stress urinary incontinence. The nomogram model based on these factors demonstrated high diagnostic performance (area under the curve\u2009=\u20090.984), suggesting potential utility for clinical application. However, this model is preliminary and requires validation in larger, multicenter cohorts before widespread use.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20503121251407038","type":"journal-article","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T09:43:59Z","timestamp":1769075039000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Prediction of risk factors for postpartum stress urinary incontinence based on pelvic floor ultrasound combined with clinical information"],"prefix":"10.1177","volume":"14","author":[{"given":"Yin","family":"Chen","sequence":"first","affiliation":[{"name":"Medical School of Nantong University, Jiangsu, China"},{"name":"Department of Radiology, Affiliated Nantong Hospital 3 of Nangtong University, Jiangsu, China"},{"name":"Yancheng Third People\u2019s Hospital, The Yancheng School of Clinical Medicine of Nanjing Medical University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6775-1244","authenticated-orcid":false,"given":"Tao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Medical School of Nantong University, Jiangsu, China"},{"name":"Department of Radiology, Affiliated Nantong Hospital 3 of Nangtong University, Jiangsu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,1,22]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.maturitas.2017.12.008"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.300.11.1311"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/gme.0b013e3181967b5d"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/medicina59010005"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349.2010.526188"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2007.08.020"},{"issue":"2","key":"e_1_3_3_8_2","first-page":"130","article-title":"Economic burden of urgency urinary incontinence in the United States: a systematic review","volume":"20","author":"Coyne KS","year":"2014","unstructured":"Coyne KS, Wein A, Nicholson S, et al.
