Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
As is usual practice, participants electing to undergo pelvic organ prolapse surgery would be offered uterine preserving surgery such as Manchester procedure (MP) as well as hysterectomy. This is done at a face to face consult with a Urogynaecologist or trainee under the supervision of a Urogynaecologist. After being provided with verbal and written information, patients will choose which procedure they will undergo to address their prolapse. All patients who choose either a MP will be offered enrolment in the study. The Manchester repair will be performed by a Urogynaecologist and/or Urogynaecology subspecialty trainee. The whole procedure would take about 1.5hrs including a cystoscopy at completion.

This is done at a face to face consult with a Urogynaecologist or trainee under the supervision of a Urogynaecologist. After being provided with verbal and written information, patients will choose which procedure they will undergo to address their prolapse. All patients who choose a VH will be offered enrolment in the study. The VH will be performed by a Urogynaecologist and/or Urogynaecology subspecialty trainee and will include a vault suspension procedure. The choice of procedure will be at the discretion of the surgeon. The whole procedure would take about 1.5hrs including a cystoscopy at completion.

Statistical methods / analysis
Outcomes were compared with Pearson chi squared test for categorical data and Student t test or Wilcoxon signed rank Test for continuous data as appropriate. 2 sided 95% confidence intervals will be used. Regression analysis will be performed as appropriate.

Pre-treatment & post-treatment changes in patient reported outcomes were analysed using Analaysis of covariance (ANCOVA) to adjust for baseline data.
