This dysfunction is related to direct injury of the pelvic organ\u2019s muscular, ligamentous or connective tissue structures due to aging, vaginal delivery or increase of the intra-abdominal pressure, for example, defecation or due to obesity. Mechanical changes alter the soft tissues\u2019 microstructural composition and therefore may affect their biomechanical properties. This study focuses on adapting an inverse finite element analysis to estimate the in vivo bladder\u2019s biomechanical properties of two groups of women (continent group (G1) and incontinent group (G2)). These properties were estimated based on MRI, by comparing measurement of the bladder neck\u2019s displacements during dynamic MRI acquired in Valsalva maneuver with the results from inverse analysis. For G2, the intra-abdominal pressure was adjusted after applying a 95% impairment to the supporting structures. The material parameters were estimated for the two groups using the Ogden hyperelastic constitutive model. Finite element analysis results showed that the bladder tissue of women with stress urinary incontinence have the highest stiffness (\u03b1\n            <jats:sub>1<\/jats:sub>\n            \u2009=\u20090.202\u2009MPa and \u00b5\n            <jats:sub>1<\/jats:sub>\n            \u2009=\u20097.720\u2009MPa) approximately 47% higher when compared to continent women. According to the bladder neck\u2019s supero-inferior displacement measured in the MRI, the intra-abdominal pressure values were adjusted for the G2, presenting a difference of 20% (4.0\u2009kPa for G1 and 5.0\u2009kPa for G2). The knowledge of the pelvic structures\u2019 biomechanical properties, through this non-invasive methodology, can be crucial in the choice of the synthetic mesh to treat dysfunction when considering personalized options.\n          <\/jats:p>","DOI":"10.1177\/09544119241237356","type":"journal-article","created":{"date-parts":[[2024,3,25]],"date-time":"2024-03-25T07:16:45Z","timestamp":1711351005000},"page":"598-607","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["An estimation of the biomechanical properties of the continent and incontinent woman bladder via inverse finite element analysis"],"prefix":"10.1177","volume":"238","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2889-4969","authenticated-orcid":false,"given":"Maria Elisabete Teixeira da","family":"Silva","sequence":"first","affiliation":[{"name":"LAETA, INEGI, Faculty of Engineering, University of Porto, Porto, Portugal"}]},{"given":"F\u00e1bio Andr\u00e9 Teixeira","family":"Pinheiro","sequence":"additional","affiliation":[{"name":"LAETA, INEGI, Institute of Biomedical Sciences Abel Salazar, Porto, Portugal"}]},{"given":"Nuno Miguel","family":"Ferreira","sequence":"additional","affiliation":[{"name":"LAETA, INEGI, Faculty of Engineering, University of Porto, Porto, Portugal"}]},{"given":"Fernanda Sofia Quintela da Silva","family":"Brand\u00e3o","sequence":"additional","affiliation":[{"name":"CESPU, Vale do Ave Higher School of Health, Department of Diagnostic and Therapeutic Technologies, Polytechnic Health Institute of North, Porto, Portugal"},{"name":"H2M \u2013 Health and Human Movement Research Unit, Department of Diagnostic and Therapeutic Technologies, Vale do Ave Higher School of Health, Polytechnic Health Institute of North, Porto, Portugal"}]},{"given":"Pedro Alexandre Lopes de Sousa","family":"Martins","sequence":"additional","affiliation":[{"name":"ARAID, i3A, University of Zaragoza, Zaragoza, Spain"}]},{"given":"Marco Paulo Lages","family":"Parente","sequence":"additional","affiliation":[{"name":"LAETA, INEGI, Faculty of Engineering, University of Porto, Porto, Portugal"}]},{"given":"Maria Teresa da Quinta e Costa","family":"Mascarenhas Saraiva","sequence":"additional","affiliation":[{"name":"Department of Gynecology and Obstetrics, Centro Hospitalar de S\u00e3o Jo\u00e3o-EPE, Faculty of Medicine, University of Porto, Porto, Portugal"}]},{"given":"Ant\u00f3nio Augusto","family":"Fernandes","sequence":"additional","affiliation":[{"name":"LAETA, INEGI, Faculty of Engineering, University of Porto, Porto, Portugal"}]},{"given":"Renato Manuel","family":"Natal Jorge","sequence":"additional","affiliation":[{"name":"LAETA, INEGI, Faculty of Engineering, University of Porto, Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2024,3,25]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/aogs.14275"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-020-04622-9"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2013.06.020"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-022-05317-z"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2007.09.025"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/9781119052258.ch2"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0301-2115(00)00527-3"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12905-021-01319-z"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2020.104275"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10237-017-0968-5"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-022-06601-0"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2022.03.045"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-011-1409-0"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1115\/1.4036606"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1080\/10255842.2017.1304542"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2018.01.033"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1590\/S0034-89102004000300015"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2014.11.045"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1142\/S0219519417500907"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-1305.2006.00257.x"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2008.06.037"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1177\/0954411916630571"},{"key":"e_1_3_2_24_2","volume-title":"Experimental and numerical studies of soft biological tissues","author":"Martins PAL","year":"2010","unstructured":"Martins PAL.
