Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Sacrocolpopexy (laparoscopic or open) - a surgical procedure using a graft material either autologous (harvested fascia lata from that patient's lateral thigh) or synthetic polypropylene mesh (TiLoop Mesh) to attach the vaginal vault to the sacral promontory in order to treat vault prolapse
Participating patients are offered sacrocolpopexy for vault prolapse as a treatment option as per the Australian Guideline - if they chose this option they are offered both fascia lata graft or synthetic polypropylene mesh. This counselling is conducted by Urogynaecology subspecialists. The patient can then select either option, there is no randominisation.
Duration of intervention - duration of surgery is between 2-4hours. Duration of expected hospital stay is between 2-4 days. Post operative review in clinic will occur at 6-8 weeks, 6 months, then yearly up to 5 years post surgery, more often if there is clinical need.
All cases included will have data collection by an independent research fellow to ensure counselling, consent, surgery and outcomes align with the study protocol.
