May 12, 2026 updated by: Adonis Hijaz, MD, University Hospitals Cleveland Medical Center

Patient-Centered Outcomes of Sacrocolpopexy Versus Uterosacral Ligament Suspension for the Treatment of Uterovaginal Prolapse

The purpose of this study is to compare two types of surgery for the treatment of uterovaginal prolapse to determine which surgery works best from a patient's perspective and has the lowest number of short-term and long-term complications.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-site, randomized controlled trial, where women with the confirmed diagnosis of uterovaginal prolapse will be randomized in a 1:1 ratio to either A) a minimally invasive supracervical hysterectomy with sacrocolpopexy (MI-SCH+SCP) or B) total vaginal hysterectomy with uterosacral ligament suspension (TVH+USLS). After surgery, participants will be followed for 3 years including physical pelvic exams and validated symptom questionnaires to assess for the primary and secondary outcomes. A subset of participants will participate in semi-structured interviews, before surgery and through 2 years after surgery, that will assess patient recovery, satisfaction with care, and calibrate surveyed and clinically assessed outcomes to the daily life experiences of women.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment failure
Time Frame: 36 months post-surgery
The primary outcome is treatment failure defined as the presence of at least one of the following: 1) presence of a vaginal bulge defined as lead point of prolapse beyond the hymen, 2) report of bothersome vaginal bulge symptoms irrespective of stage of prolapse, or 3) retreatment of symptomatic prolapse with pessary, or surgery.
36 months post-surgery

Secondary Outcome Measures

Secondary Outcome Measures
