Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised Controlled trial - 2 arms.
One arm - patients undergoing standard pelvic organ prolapse repair surgery which may include a combination of vaginal hysterectomy, anterior +/- posterior vaginal wall repair, sacrospinous fixation +/- anti-incontinence procedures. In total, the procedure may vary from 60 minutes to 120 minutes.
Intervention arm - patients undergoing standard pelvic organ prolapse repair ( as per above) will receive in addition, a puborectalis sling insertion, which is an additional 3x15cm strip of polypropylene mesh inserted via the obturator foramen, traversing the ischio-rectal fossa and post-anally from one side to the other. This additional mesh insertion may require an additional 15 - 30 minutes of surgical operating time.

Summary
Brief summary
This study aims to determine if a new technique in treating prolapse will give a better long term result than the current standard treatment. The new technique aims to reduce the size of the opening in the pelvic floor and is done at the same time as the standard prolapse repair surgery.
