Study summary

This registry was observational (only collected information typically noted by the surgeon when their patients were routinely seen); there was no change to the care the patient received as a result of being part of the registry). Data collection focused on the surgical outcomes of AMS prolapse products.

Read the detailed description

The Prolapse Registry was an observational study of patients who were implanted with AMS devices for the surgical repair of female pelvic prolapse. The registry followed patients post-operatively for up to 2 years and collected demographic, clinical, surgical, safety, and patient outcomes data.

The registry was a web-based system in which surgeons entered patient information with regard to their prolapse surgery. All information entered was de-identified (no names, no date of birth, no date of surgery, etc).

What researchers measure

Primary outcomes

  1. Count of Patients With at Least One Adverse Event Related to Any AMS Prolapse Device

    Time frame: up to 2-years post-implant

Secondary outcomes

  1. Prolapse Efficacy Success Rate

    Success was defined as either (1) Baden-Walker grade 0 or 1 or (2) (Pelvic Organ Prolapse Quantification System) POP-Q stage 0 or 1. If a site reported both measurements, then the POP-Q score was used.

    Time frame: 24 months
