INTRODUCTION AND HYPOTHESIS Treatment of anterior vaginal and/or apical prolapse by sacrocolpopexy is most often performed by systematic placement of two non-resorbable meshes, anterior and posterior, whether or not there is an associated posterior vaginal prolapse. We believe that isolated correction of an anterior vaginal and/or apical prolapse in the absence of posterior vaginal prolapse is not associated with a higher rate of de novo posterior vaginal prolapse. METHOD A prospective, observational, monocenter study performed in the Gynecology unit of the Conception UHC in Marseille from May 2011 to October 2014. Patients over 18 years of age exhibiting an anterior vaginal and/or apical prolapse of stage ≥ 2 of the POP-Q classification resulting in functional impairment with alteration of the quality of life, without an associated posterior vaginal prolapse were included and underwent a laparoscopic anterior sacrocolpopexy (ASP). They were seen again in consultation one year from the intervention. Validated quality of life questionnaires were completed pre- and one year postoperatively. RESULTS 50 patients were included. The rate of de novo posterior vaginal prolapse was 8/50 (16%). At one year, there was a significant improvement in terms of the SPDI-20 and SPIQ-7 (p < 0.0001) questionnaire, without significant improvement in the quality of sexual function (PISQ-12 questionnaire) (p = 0.073). CONCLUSION The risk of de novo posterior vaginal prolapse at one year is low when an ASP is carried out.
