Participants completed four voids (two per day). The ultrasound transducer placed on the perineum assessed bladder neck and urethral displacement during micturition. On Day 1, a void with ultrasound and uroflow recorded by a sonographer was compared to a void recorded with uroflowmetry only to determine whether the transducer placement affected voiding. On Day 2, two sonographers evaluated the voids with ultrasound and uroflowmetry. Each sonographer measured their own images. One sonographer also made measures on the images recorded by the second sonographer. Uroflowmetry measures and void patterns were evaluated. The repeatability of ultrasound measures was analyzed using intraclass correlation coefficient (ICC 2,1) and Bland\u2013Altman analysis, and <jats:italic>t<\/jats:italic> tests examined the transducer's impact on uroflowmetry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Some changes in flow rate and flow pattern (20% of participants) were observed with placement of the transducer. Most sonographic measures showed good to excellent inter\u2010 and intra\u2010tester repeatability, and between measures made by the different testers on the same image. During void, bladder neck and urethral diameter were more repeatable if measures were made at the time of maximum flow estimated from the simultaneous uroflowmetry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Voiding sonography is both feasible and repeatable. Perineal transducer placement affected micturition for some individuals. Voiding sonography combined with uroflowmetry shows promise for a noninvasive urogynecology functional assessment.<\/jats:p><\/jats:sec>","DOI":"10.1111\/luts.70020","type":"journal-article","created":{"date-parts":[[2025,7,9]],"date-time":"2025-07-09T14:48:37Z","timestamp":1752072517000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Repeatability Study of Measurement of Micturition With Voiding Sonography and Uroflowmetry of Asymptomatic Women"],"prefix":"10.1111","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1221-3164","authenticated-orcid":false,"given":"Bernadette","family":"Dellar","sequence":"first","affiliation":[{"name":"School of Health and Rehabilitation Sciences The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan","family":"Stafford","sequence":"additional","affiliation":[{"name":"School of Health and Rehabilitation Sciences The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3373-3668","authenticated-orcid":false,"given":"Eric","family":"Chung","sequence":"additional","affiliation":[{"name":"Faculty of Medicine The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel","family":"Schaer","sequence":"additional","affiliation":[{"name":"Department of Gynaecology The University Hospital of Zurich  Z\u00fcrich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margret","family":"Sherburn","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy The University of Melbourne  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roxanna","family":"Turner","sequence":"additional","affiliation":[{"name":"Queensland Radiology Specialists  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Handoo","family":"Rhee","sequence":"additional","affiliation":[{"name":"Faculty of Medicine The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Page","sequence":"additional","affiliation":[{"name":"Evelina Children's Hospital Guys and St Thomas' NHS Foundation  UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1206-9107","authenticated-orcid":false,"given":"Paul W.","family":"Hodges","sequence":"additional","affiliation":[{"name":"School of Health and Rehabilitation Sciences The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,8]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.20798"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/nau.20718"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aju.2013.07.005"},{"issue":"2","key":"e_1_2_11_5_1","first-page":"144","article-title":"Voiding Difficulties in the Female: Prevalence, Clinical and Urodynamic Review","volume":"61","author":"Stanton S.
