Studies of women who underwent vaginal surgery for uterine or post-hysterectomy vaginal vault prolapse were eligible for inclusion if surgery had involved the placement of a mesh kit (Posterior Prolift, Apogee, intravaginal slingplasty, or infracoccygeal sacropexy) for repair of the vaginal apex. Eligible studies were required to report objective and subjective outcomes (as defined in the review) that related to prolapse, urinary, bowel, sexual function, pain, mesh erosion and perioperative surgical complications. Studies that described the use of mesh to support the anterior or posterior vaginal compartment alone, used mesh for incontinence or fistula repair or did not involve the upper vaginal compartment were excluded. Eligible study designs were cross-sectional, case series, case-control, any design with historical controls, cohort or controlled trials.
Some of the included studies involved concomitant procedures, including vaginal hysterectomy and Manchester repair.
The authors did not state how many reviewers screened studies for inclusion.
