The surgical approaches included 13 procedures via the anterior fornix, 16 via the lateral fornix, and 60 via the posterior fornix. The anterior fornix approach was primarily used for lateral suspension for pelvic organ prolapse (POP). All procedures were completed safely, with the longest follow-up exceeding 2\u202fyears, and no cases of mesh exposure were observed. Overall, three patients (23.08%) experienced Grade I complications. The lateral fornix approach was primarily used for lymphadenectomy, and all procedures were completed safely. A total of four cases (25.00%) of Grade I complications and one case (6.25%) of Grade II complications were recorded. The posterior fornix approach was primarily used for sacrocolpopexy and sacrospinous ligament fixation (SSLF), with all procedures completed safely. In the sacrocolpopexy group, three Grade I complications (30.77%) and one Grade III complication (7.69%) were observed. In the SSLF group, eight Grade I complications (17.02%) were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this retrospective study, retroperitoneal vNOTES was demonstrated to be a safe and feasible approach. By using different vaginal fornix incisions, it can be adapted to a wide range of procedures, including surgeries for POP and resection of both pelvic and para-aortic lymph nodes.<\/jats:p>\n
