April 22, 2026 updated by: Julia Geynisman-Tan, Northwestern University

REDUCE Trial - Reducing Prolapse Recurrence by Reducing the Genital Hiatus

This study will examine whether surgeons should add a prophylactic posterior colpoperineorrhaphy to a mesh-augmented apical prolapse repair.

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

The decision to perform a posterior colpoperineorrhaphy at the time of sacrocolpopexy is controversial. Based on cohort data, some surgeons advocate that sacrocolpopexy alone is effective at treating posterior vaginal wall prolapse and the addition of posterior colpoperineorrhaphy only increases the likelihood of pain with defecation and dyspareunia. Experts theorize that placement of posterior vaginal mesh down to the perineal body provides adequate posterior support and reduces genital hiatus size. Others argue that placement of mesh too low on the posterior vagina may be associated with increased mesh exposure and pain secondary to mesh stiffness. No randomized trials exist comparing prolapse outcomes using new, ultra-light polypropylene mesh with and without posterior colpoperineorrhaphy. The investigators hypothesize that there will be no difference in prolapse outcomes after sacrocolpopexy using Restorelle mesh with and without posterior colpoperineorrhaphy. However, patients with a posterior colpoperineorrhaphy will be more likely to report pain with defecation and dyspareunia. This will be the first multicenter randomized trial comparing outcomes of sacrocolpopexy with and without posterior colpoperineorrhaphy.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
200

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Women over the age of 18
  • English or Spanish speaking
  • Symptomatic prolapse (stage II or greater) undergoing minimally-invasive sacrocolpopexy with Restorelle ultra lightweight mesh
  • Preoperative genital hiatus with valsalva/strain greater than or equal to 4cm

Exclusion Criteria:

  • Patient has had prior prolapse surgery
  • Patient has inflammatory bowel disease (Crohn's, Ulcerative Colitis)
  • Baseline dyspareunia (patient reports that they have pain with vaginal intercourse when asked as a yes/no)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Sacralcolpopexy with posterior colpoperineorrhaphy
Procedure: Posterior colpoperineorrhaphy
Patients having a sacralcolpopexy will be randomized to ultra lightweight mesh (Coloplast Restorelle) with posterior colpoperineorrhaphy or the same procedure without the posterior colpoperineorrhaphy
No Intervention: Sacralcolpopexy without posterior colpoperineorrhaphy

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
Pelvic Organ Prolapse Quantification (POP-Q) System
Time Frame: 1 Year
The POP-Q System will be used to compare the rate of prolapse recurrence at 1 year between women undergoing a sacrocolpopexy with Restorelle mesh with and without a concomitant posterior colpoperineorrhaphy.
1 Year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Defecatory Dysfunction
Time Frame: 1 Year
To compare the rates of defecatory dysfunction using the Bristol Stool Scale (stool types measured from type 1-type 7) and the Colorectal-Anal Distress Inventory 8 (measured from 0-100 points).

Dyspareunia
Time Frame: 1 Year
To compare the rates of dyspareunia between groups using the Female Sexual Function Index (measured from 2-36 points)
1 Year
Surgical and Perioperative Events: Blood Loss
Time Frame: 2 Weeks
To compare the estimated blood loss (in milliliters) between groups.

Surgical and Perioperative Events: Operative Time
Time Frame: Day of surgery
To compare the operative time (in minutes as listed on the surgical case tracking) between groups.
