Materials and methods: Modified Oxford Scale (MOS) was used for clinical evaluation of muscle contraction. The parameters obtained in both ultrasound approaches were assessed for all six Oxford grades. The values of \u0394H, \u0394D and vector, measured at rest and on pelvic floor muscle contraction, were used to evaluate urethral mobility parameters in both ultrasound methods. Patients with a history of urogynecological surgery, pelvic radiotherapy, significant pelvic prolapse (grade 2 or grater in at least one compartment), as well as those with unilateral or bilateral complete avulsion of the puborectalis muscle were excluded. Results: A total of 272 women were included in the analysis. A statistically significant correlation was found between the contraction force and urethral mobility parameters \u0394H and vector-positive and \u0394D-negative, obtained in both ultrasound approaches. However, no correlation was demonstrated between the contraction force and changes in the analyzed hiatal parameters. The Bland-Altman analysis showed a high agreement of both measurement methods. Conclusions: The force of pelvic floor muscle contraction, as measured with the Oxford Scale, correlated with urethral mobility in both ultrasound examinations. Assessment of urethral mobility using the three assessed parameters (\u0394H, \u0394D, vector) allows for the most comprehensive analysis. Only minor differences were found in the analyzed urethral mobility parameters between both ultrasonographic approaches. The impact of pelvic floor muscle contraction on the size of the urogenital hiatus was not confirmed.<\/jats:p>","DOI":"10.15557\/jou.2025.0005","type":"journal-article","created":{"date-parts":[[2025,2,11]],"date-time":"2025-02-11T12:55:11Z","timestamp":1739278511000},"source":"Crossref","is-referenced-by-count":0,"title":["The impact of pelvic floor contraction on urethral mobility and urogenital hiatus size in pelvic floor ultrasound"],"prefix":"10.15557","volume":"25","author":[{"name":"Gynecology and Obstetrics Clinic, NZOZ Ginekomed Dorota Dobek, Poland","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5474-7027","authenticated-orcid":false,"given":"Marta","family":"Dobek-Bryli\u0144ska","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6453-1500","authenticated-orcid":false,"given":"Edyta","family":"Wla\u017alak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Clinic of Operative and Oncologic Gynecology, 1st Department of Gynecology and Obstetrics, Medical University of Lodz, Poland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7051-8536","authenticated-orcid":false,"given":"Wiktor","family":"Wla\u017alak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Clinic of Operative and Oncologic Gynecology, 1st Department of Gynecology and Obstetrics, Medical University of Lodz, Poland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3435-9658","authenticated-orcid":false,"given":"Jan","family":"Krakowiak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Social Medicine, Chair of Social and Preventive Medicine, Medical University of Lodz, Poland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5772-0573","authenticated-orcid":false,"given":"Andrzej","family":"Wr\u00f3bel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"2nd Chair and Department of Gynecology, Medical University in Lublin, Poland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2435-9865","authenticated-orcid":false,"given":"Grzegorz","family":"Surkont","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Clinic of Operative and Oncologic Gynecology, 1st Department of Gynecology and Obstetrics, Medical University of Lodz, Poland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"6250","published-online":{"date-parts":[[2025,3,13]]},"container-title":["Journal Of Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/jultrason.pl\/assets\/pdf\/artykuly\/plik.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T13:09:09Z","timestamp":1741957749000},"score":1,"resource":{"primary":{"URL":"https:\/\/jultrason.pl\/index.php\/issues\/volume-25-no-100-open-issue\/the-impact-of-pelvic-floor-contraction-on-urethral-mobility-and-urogenital-hiatus-size-in-pelvic-floor-ultrasound"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3,13]]},"references-count":0,"journal-issue":{"issue":"100","published-online":{"date-parts":[[2025,3,13]]},"published-print":{"date-parts":[[2025,3,13]]}},"URL":"https:\/\/doi.org\/10.15557\/jou.2025.0005","relation":{},"ISSN":["2084-8404","2451-070X"],"issn-type":[{"type":"print","value":"2084-8404"},{"type":"electronic","value":"2451-070X"}],"subject":[],"published":{"date-parts":[[2025,3,13]]}}}
