Methods	RCT (computer‐generated number table, opaque envelopes) on posterior IVS and sacrospinous fixation for vault prolapse Median follow‐up: Gp A 19, Gp B 17 months
Participants	66 randomised, no stratification A 33, B 33 No withdrawals or losses to follow‐up Inclusion: vault (vaginal cuff) prolapse ICS stage 2 or more Baseline stress urinary incontinence: A 11/33, B 7/33 Baseline overactive bladder: A 14/33, B 11/33 Baseline voiding dysfunction: A 19/33, B 18/33 Women in group A were significantly younger than those in group B (63 yrs vs 68 yrs, P < 0.05)
Interventions	Gp A (33): infracoccygeal sacropexy (posterior IVS) using multifilament polypropylene tape Gp B (33): sacrospinous ligament fixation (vaginal sacrospinous colpopexy) Concomitant surgery: anterior (A 64%, B 66%) and posterior (70%, 88%) repair, high closure of pouch of Douglas if indicated (36%, 42%)
Outcomes	Reports the following review outcomes at median 17‐ to 19‐month follow‐up: Awareness of prolapse (subjective prolapse sensation) Objective failure of anterior compartment; posterior compartment (POPQ stage 2 or more) Operative time Days in hospital
