A 27-year-old patient was diagnosed as well-differentiated cervical adenocarcinoma, stage IB1, and had a strong desire for future fertility. Laparoscopic radical trachelectomy with uterine artery preservation was performed in this patient by using this new surgical technique based on space anatomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The ureteral space that needs to be dealt with during laparoscopic radical trachelectomy is actually a potential avascular space located medial to the ureter between the anterior leaf (from the axillary space to the fourth space of Yabuki) and posterior leaf (between the paravesical space and paravaginal space) of the vesicouterine ligament. Exposure of the axillary space can help to separate the ureter from the lower uterine segment and uterine artery (uterine side), which is necessary for radical trachelectomy with uterine artery preserved. Multiple \u201cshafts\u201d called potential avascular space can be drilled on the anterior leaf of vesicouterine ligament, and the connective tissue and blood vessels between the \u201cshafts\u201d were cutoff with ultrasonic scalpel. After the paravesical space and paravaginal space were developed, the posterior leaf was isolated and congealed completely by Ligasure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>In brief, this new surgical procedure consists of four spaces that can safely and efficiently perform complete excision of the vesicouterine ligament, reduce blood loss, avoid ureteral injury, and shorten the operation time.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/lap.2020.0461","type":"journal-article","created":{"date-parts":[[2020,10,21]],"date-time":"2020-10-21T15:48:01Z","timestamp":1603295281000},"page":"705-709","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Surgical Technique Based on Space Anatomy for Laparoscopic Radical Trachelectomy with Uterine Artery Preservation"],"prefix":"10.1177","volume":"31","author":[{"given":"Xiaoming","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiwei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhong","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yudong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China."},{"name":"Shanghai Municipal Key Clinical Specialty of Gynecologic Oncology, Shanghai, China."},{"name":"Shanghai Key Laboratory of Embryo Original Diseases Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,6,2]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.2016.290"},{"key":"e_1_3_4_3_2","first-page":"1","article-title":"First births to older women continue to rise","volume":"152","author":"Matthews TJ","year":"2014","unstructured":"Matthews TJ, , Hamilton BE.
