Bandl first described this condition, of abnormal retraction of the uterus occurring during obstructed labor, characterized by a constriction between the thinned lower uterine segment and the thick, retracted upper uterine portion. To determine the incidence and the maternal and perinatal outcome in pregnancies showing Bandl\u2019s ring by reviewing the published literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpm-2025-0243_abs_002\">\n                    <jats:title>Content<\/jats:title>\n                    <jats:p>PubMed, Embase and Google Scholar Search searches were made using \u201cBandl\u2019s ring.\u201d Papers selected were assessed independently for content, data extraction and analysis. The following parameters were included for the analysis: total number of reported cases, use of ultrasound, fetal position and station, labor augmentation, modality of delivery, indications for cesarean section, neonatal complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpm-2025-0243_abs_003\">\n                    <jats:title>Summary and Outlook<\/jats:title>\n                    <jats:p>The literature search identified nine articles that met the established inclusion criteria and were deemed eligible for analysis and comparison, encompassing a total of 23 clinical cases. Ultrasound was used 21\u202f% of the cases. The fetal occiput was posterior in 93\u202f% of the cases, augmentation of labor in 39\u202f%, cesarean section was necessary in 95.6\u202f% of cases and there were three cases of severe neonatal complications (13\u202f%). Bandl\u2019s ring represents a rare yet clinically significant intrapartum pathology. This study highlights the importance of early recognition and appropriate management of Bandl\u2019s ring. Incorporating ultrasound into the assessment of obstructed labor may enhance obstetricians\u2019 ability to accurately identify this condition, thereby minimizing the risks associated with delayed or inappropriate intervention.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1515\/jpm-2025-0243","type":"journal-article","created":{"date-parts":[[2025,7,11]],"date-time":"2025-07-11T11:58:11Z","timestamp":1752235091000},"page":"959-965","source":"Crossref","is-referenced-by-count":0,"title":["The incidence of Bandl\u2019s ring and its impact on labor outcomes: a review of the published literature"],"prefix":"10.1515","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9866-3050","authenticated-orcid":false,"given":"Ilenia","family":"Mappa","sequence":"first","affiliation":[{"name":"Department of Maternal and Child Health and Urological Sciences , Universit\u00e0 di Roma Sapienza , Rome , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Malvasi","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology Unit, Department of Interdisciplinary Medicine (DIM) , Universit\u00e0 di Bari , Bari , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martina","family":"Derme","sequence":"additional","affiliation":[{"name":"Department of Maternal and Child Health and Urological Sciences , Universit\u00e0 di Roma Sapienza , Rome , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe Maria","family":"Maruotti","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology , Universit\u00e0 di Napoli Federico II , Naples , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"D\u2019Antonio","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology , Universit\u00e0 di Chieti , Chieti , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5525-4353","authenticated-orcid":false,"given":"Giuseppe","family":"Rizzo","sequence":"additional","affiliation":[{"name":"Department of Maternal and Child Health and Urological Sciences , Universit\u00e0 di Roma Sapienza , Rome , Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2025,7,14]]},"reference":[{"key":"2026051215163792488_j_jpm-2025-0243_ref_001","doi-asserted-by":"crossref","unstructured":"Friedman, EA, Cohen, WR.
