POPQ Versus Simulated Apical Support as a Guideline for Anterior or Posterior Repair During Vaginal Reconstruction

Preoperative POPQ Versus Simulated Apical Support as a Guideline for Anterior or Posterior Repair at the Time of Transvaginal Apical Suspension

The objective of the Preoperative Pelvic Organ Prolapse Quantification (POPQ) versus Simulated Apical Support as a Guideline for Anterior or Posterior Repair at the Time of Transvaginal Apical Suspension (PREPARE) trial is to compare surgical outcomes of POPQ-based surgery with simulated apical support-based surgery for anterior or posterior vaginal wall prolapse at the time of transvaginal apical suspension.

Study Overview

• Status: Active, not recruiting
• Conditions: Pelvic Organ Prolapse
• Intervention / Treatment: Procedure: anterior or posterior colporrhaphy

Detailed Description

The PREPARE trial is a prospective, randomized trial conducted with the aim to determine non-inferiority of the primary outcome between POPQ-based surgery and simulated apical support-based surgery for anterior or posterior vaginal wall prolapse. Participants will undergo transvaginal surgery for prolapse, including the assigned procedure for anterior or posterior vaginal prolapse under general or spinal anesthesia. Concomitant procedures will be performed as intended prior to surgery. Women with a uterus in situ will undergo hysterectomy and all women will receive transvaginal vault suspension, including uterosacral ligament suspension, sacrospinous ligament fixation, and iliococcygeal suspension with both delayed absorbable and permanent sutures, according to the preference of surgeon. Incontinence surgery will also be performed for women with documented urodynamic stress incontinence.

A standardized protocol for enrollment, treatment and data collection will be employed by all sites. The study will be a single-blind study, as it is impossible to blind the study surgeon for the surgical procedure to which the subject in assigned. However, it is our intent that when feasible and ethical, all outcomes assessors and the subjects will be blinded to the treatment assignment. Postoperative follow-up will take place after 5 weeks and 6, 12, and 24 months. Patients will undergo a standard gynecological examination including POPQ and fill in questionnaires.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: POPQ-based surgery; will undergo anterior or posterior colporrhaphy for all of anterior or posterior vaginal prolapse stage 2 or greater (i.e. point Ba or Bp ≥-1 on the POPQ examination)	Procedure: anterior or posterior colporrhaphy; will be performed in a traditional manner with midline plication of the fibromuscular layer using 2-0 delayed absorbable sutures.
Experimental: Simulated apical support-based surgery; will undergo anterior or posterior colporrhaphy only for the prolapse unresolved under simulated apical support (i.e. point Ba or Bp ≥-1 under simulated apical support)	Procedure: anterior or posterior colporrhaphy; will be performed in a traditional manner with midline plication of the fibromuscular layer using 2-0 delayed absorbable sutures.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Surgical success at 2 years after surgery	surgical success is defined as the absence of all of the following criteria: (1) anterior or posterior vaginal descent beyond the hymen (i.e., point Ba or Bp >0); (2) descent of the vaginal apex beyond the half-way point of vagina (i.e., point C > -1/2×total vaginal length); (3) vaginal bulge symptoms; (4) re-treatment for prolapse by either surgery or pessary.	From date of surgery until the date of first documented failure, assessed up to 2 years after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of anterior or posterior colporrhaphy	rate of anterior or posterior colporrhaphy performed during surgery	At date of surgery
Change of POPQ values	point Ba, C, Bp and TVL	From baseline to 2 years after surgery
Change of PFDI-20 scores	the PFDI-20 is a valid and reliable condition-specific quality-of-life questionnaires for women with pelvic floor disorders. It has 20 items and 3 scales (Pelvic Organ Prolapse Distress Inventory, Colorectal-Anal Distress Inventory and Urinary Distress Inventory). Each scale is scored from 0 to 100; higher scores indicate greater symptom burden. The PFDI-20 total score is obtained by adding the scores from the 3 scale scores together (0-300).	From baseline to 2 years after surgery
Change of pelvic floor impact questionnaire (PFIQ-7) scores	the PFIQ-7 is a valid and reliable condition-specific quality-of-life questionnaires for women with pelvic floor disorders. It has 7 questions and each question has 3 separate responses (one for each of 3 scales; Urinary Impact Questionnaire, Colo-rectal-anal Impact Questionnaire, and Pelvic Organ Prolapse Impact Questionnaire). Each scale is scored from 0 to 100; higher scores indicate greater symptom burden. The PFIQ-7 total score is obtained by adding the scores from the 3 scales together (0-300).	From baseline to 2 years after surgery
Change of Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ)-12 scores	the PISQ-12 is a valid and reliable condition-specific questionnaire that evaluates sexual function in women with urinary incontinence and/or pelvic organ prolapse. It has 12 items and responses are graded on a five-point Likert scale ranging from 0 to 4. A total of 48 is the maximum score; higher scores indicate better sexual function.	From baseline to 2 years after surgery
Operating times	mean or median minutes of operating times	At date of surgery
Estimated blood loss	mean or median mililiters of estimated blood loss	At date of surgery
Length of hospital stay	mean or median days of hospital stay	From date of admission to date of discharge, estimated average 4 days
Rate of adverse events	rate of cardiovascular, pulmonary, gastrointestinal, genitourinary, and neurological complications	From date of surgery to 2 years after surgery
