NCT06754046

Brief Summary

The goal of this clinical trial is to learn if retropubic midurethral sling (RP-MUS) or bulkamide injection (PAHG) at the time of pelvic organ prolapse repair is better from the patient's perspective. The main questions it aims to answer are: What is the average difference in the urogenital distress inventory (UDI) long form score 24 months after surgery for each procedure? Which procedure has the fewest complications and lowest short- and long-term morbidity profile? Participants will: Be blinded and randomized to one of two procedures for the duration of the study, 24 months. Complete 6 total visits for the clinical trial including validated questionnaires. Few participants will be selected to complete a qualitative interview at 3 timepoints over 24 month duration of the study.

Outcome Measures

Primary Outcomes (1)

  • Bothersome stress urinary incontinence symptoms as measured by urogenital distress inventory long form (UDI)

    a questionnaire used to assess the severity of lower urinary tract symptoms like incontinence, particularly in women, by measuring the impact of these symptoms on their quality of life. Scores range from 0 to 100, higher number indicates worse symptoms.

    24 months postoperatively

Secondary Outcomes (7)

  • Change in bothersome stress urinary incontinence symptoms as measured by urogenital distress inventory long form (UDI)

    1, 6 and 12 months postoperatively

  • Change in patient assessment of improvement as measured by the Patient Global Impression of Improvement (PGI-I)

    1 month, 6 months, 12 months and 24 months postoperatively

  • Number of retreatment for SUI as measured by medical record review/patient report

    up to 24 months post operatively

  • Change in Lower urinary tract dysfunction research network symptom index-29 (LURN-SI-29)

    preoperatively, 1, 6, 12 and 24 months postoperatively

  • Change in Female Sexual Function Inventory (FSFI)

    preoperatively, 1, 6, 12 and 24 months postoperatively

  • +2 more secondary outcomes

Study Arms (2)

Retropubic Midurethral Sling (RP-MUS)

ACTIVE COMPARATOR

A minimally invasive surgical procedure that treats stress urinary incontinence (SUI) in women by placing a small strip of tape passed through the retropubic space, with entry and exit points in the lower abdomen or groin.

Device: RP-MUS

Urethral Bulking with polyacrylamide hydrogel (PAHG)

ACTIVE COMPARATOR

PAHG will be performed using the standard 2 mL dose injection order and number will be at the discretion of the surgeon. Patients undergoing PAHG will be given sham incisions consisting of superficial suprapubic epidermal scratches with a needle and fibrin glue at expected sling exit sites.

Procedure: PAHG

Interventions

RP-MUSDEVICE

a standard urethral sling placement for treatment of stress urinary incontinence

PAHGPROCEDURE

A standard 2 mL dose injection of bulkamid (order and number will be at the discretion of the surgeon) will be given. Patients undergoing PAHG will be given sham incisions consisting of superficial suprapubic epidermal scratches with a needle and fibrin glue at expected sling exit sites.

  • Anticipation of pregnancy within subsequent 24-months or \<18 months post-partum
  • Hemoglobin A1c \>10.0% within the past 3-months
  • Current smoker \> 1 pack per week
  • History of neurogenic bladder
  • Current use of any catheterization including but not limited to, intermittent catheterization, indwelling Foley catheter, or suprapubic catheter
  • Post-void residual \>150 mL felt to not be due to obstruction for prolapse
  • Prior history of any anti-incontinence procedure including but not limited to any synthetic sling, fascial sling, Burch colposuspension or its variants, and urethral bulking
  • Previous history of any pelvic radiation
  • Patient receiving a planned concurrent procedure at the time of prolapse repair.
