Surgical treatment of genital prolapse can be performed by laparoscopic surgery or by vaginal surgery, with or without using meshes. Laparoscopic sacrocolpopexy, which consist in fixing a mesh between vaginal anterior wall and the promontory is the gold standard procedure to treat anterior prolapse or of the vaginal vault. Most of studies shows a success rate of 80% of this procedure.

However, access to the promontory could be difficult in patients because of adherences or anatomical reasons. This step of the procedure also exposes to risk of ureteral or vascular injuries. Recent issues have also found spondylodiscitis cases.

The technique of laparoscopic lateral suspension with mesh was developed by Dubuisson in 1998 allows not to have to approach the promontory and avoids both the risk of vascular injury and ureteral damage of laparoscopic sacrocolpopexy. Instead of attach the mesh to the promontory, the procedure consists in spreading out bilaterally, a subperitoneal T-shaped mesh in the anterior abdominal wall. The aim of this study is to compare the clinical and functional efficiency of the lateral suspension versus laparoscopic sacrocolpopexy.

It is a prospective, randomized, monocentric study compared two groups The study hypothesis is that the lateral suspension would provide correction than the laparoscopic sacrocolpopexy.

The primary outcome is the comparison of anatomic correction rates at 1 year Success is defined as 1 year Ba et C points < -1 centimeter in POP-Q international score.

Secondary endpoints are improve of quality of life evaluated with the validated P-QOL questionnaire, and complications rates, including post-operative posterior prolapse.

Number of subjects required is 72 patients, 36 in each group having a laparoscopic sacrocolpopexy or lateral suspension.

Outcomes will be evaluated at 1 month and 1 year post-operative consultation
