Pelvic floor trauma in the form of partial or complete avulsions of the levator ani muscle (LAM) affects 6-42% of women after vaginal birth and can cause tremendous long-term morbidity. Many studies assessed morphological pelvic floor trauma after childbirth but lacked to evaluate women\u2019s associated short-term complaints. A proper assessment of trauma and subjective complaints after birth could help to assess possible associations between them and their relevance to women\u2019s daily life. Therefore, we aimed to assess women\u2019s complaints within the first months after birth in association to their LAM trauma. Materials and Methods. Between 3\/2017 and 4\/2019, we prospectively evaluated vaginal births of 212 primiparous women with singletons in <jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mtext>vertex<\/a:mtext>\n                        <a:mtext>\u2009<\/a:mtext>\n                        <a:mtext>presentation<\/a:mtext>\n                        <a:mo>\u2265<\/a:mo>\n                        <a:mn>36<\/a:mn>\n                        <a:mo>+<\/a:mo>\n                        <a:mn>0<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula> gestational weeks for levator ani muscle (LAM) trauma by translabial ultrasound, for pelvic organ prolapse by clinical examination, and for urogynecological complaints using questionnaires 1-4 days (P1), 6-10 weeks (P2), and 6-9 months (P3) after birth. The questionnaires were self-designed but oriented to and modified from validated questionnaires. Women\u2019s complaints were evaluated for P1-P3 according to their LAM trauma state. Results. At P1, 67% of women showed an intact LAM, whereas 14.6% presented a hematoma, 6.6% a partial avulsion (PAV), and 11.8% a complete avulsion (CAV). At P2, 75.9% showed an intact LAM, 9.9% a PAV, and 14.2% a CAV. At P3, 72.9% of women with a LAM trauma in P1 and\/or P2 were assessed with 21.6% being intact and 39.2% having a PAV and CAV, respectively. Obstetrical and baseline characteristics differed slightly between the groups. When comparing the time before and during pregnancy with the time after childbirth, birth itself affected women\u2019s complaints in all LAM state groups, but the presence of a LAM trauma, especially a CAV, had more negative effects. Conclusions. Vaginal birth changes the anatomical structure of the maternal birth canal and genital tract, and it alters women\u2019s perceptions and body function. In our study, LAM trauma did not change these effects tremendously within the first months. Therefore, other maternal, fetal, and obstetrical factors need consideration for the explanation of maternal complaints, in addition to long-term effects of trauma and dysfunction of the LAM and other birth canal structures.<\/jats:p>","DOI":"10.1155\/2022\/4197179","type":"journal-article","created":{"date-parts":[[2022,9,5]],"date-time":"2022-09-05T22:20:15Z","timestamp":1662416415000},"page":"1-17","source":"Crossref","is-referenced-by-count":3,"title":["Associations of Maternal Complaints to Levator Ani Muscle Trauma within 9 Months after Vaginal Birth: A Prospective Observational Cohort Study"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0789-425X","authenticated-orcid":true,"given":"N.","family":"Kimmich","sequence":"first","affiliation":[{"name":"Division of Obstetrics, University Hospital of Zurich, Raemistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Birri","sequence":"additional","affiliation":[{"name":"Division of Obstetrics, University Hospital of Zurich, Raemistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Richter","sequence":"additional","affiliation":[{"name":"Division of Obstetrics, University Hospital of Zurich, Raemistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Zimmermann","sequence":"additional","affiliation":[{"name":"Division of Obstetrics, University Hospital of Zurich, Raemistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Kreft","sequence":"additional","affiliation":[{"name":"Division of Obstetrics, University Hospital of Zurich, Raemistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/1471-0528.12676"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000178779.62181.01"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2011.03152.x"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2010.02704.x"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2009.03.028"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-020-04297-2"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgo.2010.05.019"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1523-536X.2008.00222.x"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1111\/ajo.12286"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.2005.00363.x"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2003.09.047"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2009.02.005"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0412.2011.01315.x"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2006.00819.x"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1002\/uog.1072"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1002\/uog.11190"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-010-1329-4"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-020-04669-8"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1111\/aogs.13660"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.4414\/smw.2020.20280"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0b013e3181d534cd"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1002\/uog.20159"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1097\/SPV.0000000000000644"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2019.03.004"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.3109\/00016349.2010.526188"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1111\/j.1523-536X.2007.00175.x"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-020-04636-3"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2006.06.062"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-014-2331-z"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1016\/j.esxm.2019.10.005"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.1067\/mob.2001.113855"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgo.2004.12.019"},{"key":"33","doi-asserted-by":"publisher","DOI":"10.1111\/1471-0528.13331"},{"key":"34","doi-asserted-by":"publisher","DOI":"10.1111\/aogs.13852"},{"key":"35","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-016-3208-0"},{"key":"36","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2010.01.002"},{"key":"37","volume-title":"Associations of maternal complaints to levator ani muscle trauma within 9 months after vaginal birth","author":"N.
