Subjective outcome is the patients' response 'no' to question 2 of the PFDI (pelvic heaviness). The composite outcome is a strictly binary categorization where any residual sense of pelvic heaviness/vaginal bulging results in the classification of the patient as a failure. It also includes the components of the main secondary outcome considered individually, any adverse events in the aftermath of surgery, as well as, patient-reported urogenital distress (UDI), quality of life (PFIQ) and sexual function (PISQ-12) as measured by the self-reported questionnaires. For secondary analyses, the ordinal grading of responses to the PFDI-20, PFIQ-7 and PISQ-12 will be used to determine rates of improvement and progression over time.

Mesh measurements: Total mesh midsagittal length, length above and below the bladder neck (BN) level. Distance between mesh lower edge and pubis symphysis (PS) lower edge and PS level.

Bladder neck: Distance between BN and PS levels. Distance between BN and PS lower edge.

Urethra: Total urethra length. Distance between mid-urethra and PS lower edge and PS level.

Using identical examination protocol, independent examination at rest and physical strain is to be done by senior gynecologist at an ultrasound referral unit and gynecologist. Estimation of intra class coefficient (ICC) in-between examiners in order to determine method reproducibility.

To statistically compare between the collected ultrasound data and clinical outcomes. Clinical outcomes include anatomical, subjective and sexual function outcome.

VAS scale is a numeric rating scale and ranges from 0-10 (each digit is 1cm) where 0 indicates no and 10 indicates maximum, digits between 0-10 indicate degree of pain.

VAS scale is a numeric rating scale and ranges from 0-10 (each digit is 1cm) where 0 indicates no and 10 indicates maximum, digits between 0-10 indicate degree of severity of urinary incontinence. VAS scale for urinary incontinence: 0 indicate no urinary incontinence whereas 10 indicates maximal or severe urinary incontinence.

VAS scale is a numeric rating scale and ranges from 0-10 (each digit is 1cm) where 0 indicates no and 10 indicates maximum, digits between 0-10 indicate degree of satisfaction after mesh surgery. VAS scale for patient satisfaction: 0 indicates no satisfaction whereas 10 indicates maximal satisfaction.

VAS scale is a numeric rating scale and ranges from 0-10 (each digit is 1cm) where 0 indicates no and 10 indicates maximum, digits between 0-10 indicate degree of satisfaction. VAS scale for patient recommendation to other patients to undergo same surgery if they suffer apical prolapse: 0 indicates no recommendation whereas 10 indicates maximal recommendation.
