- Brief Summary
Pelvic organ prolapse is common among women with a prevalence that has been estimated to be as high as 30%. Prolapse may be corrected by surgery using either a vaginal or abdominal incision. Some women develop stress urinary incontinence (SUI) after surgery. A prior randomized trial has shown that use of a Burch sling at the time of an abdominal sacrocolpopexy decreases the risk of urinary incontinence; however, the benefit of adding an anti incontinence procedure to prevent SUI at the time of prolapse surgery performed via a vaginal approach is unclear. Thus, the objective of the Outcomes following vaginal Prolapse repair and mid Urethral Sling (OPUS) trial is to determine whether prophylactic treatment with Tension-free Vaginal Tape (TVT)® at the time of prolapse surgery done via a vaginal approach is effective in preventing urinary incontinence.
- Detailed Description
The overall objective of this randomized clinical trial is to determine whether symptom-specific treatment of incontinence after prolapse surgery is equally effective to prophylactic treatment by adding TVT® at the time of the prolapse surgery among women with anterior vaginal prolapse but without pre-operative symptoms of stress urinary incontinence.
The primary aims are:
In stress continent women planning vaginal surgery for pelvic organ prolapse:
1. To determine if the failure rate defined by subsequent treatment for urinary incontinence, signs or symptoms of bothersome urinary incontinence \[defined as having at least moderate bother for any of 4 Pelvic Floor Distress Inventory (PFDI) incontinence items\] differs between vaginal prolapse repair and vaginal prolapse repair plus TVT® during the first 3 months after the index surgery.
2. To determine if the prevalence of bothersome urinary incontinence at 12 months after the index surgery differs between vaginal prolapse repair and vaginal prolapse repair plus TVT®, whether or not there was subsequent treatment for symptoms of urinary incontinence; i.e., to determine whether symptom-specific treatment of incontinence after prolapse surgery is equally effective to prophylactic treatment by adding a TVT® at the time of the prolapse surgery.
3. To measure the total cost of care and relate the difference in cost of care between the two groups to differences in health utilities and health-related quality of life, which will allow us to examine the cost-effectiveness of prophylactic use of a TVT® at the time of prolapse surgery versus symptom-specific treatment of stress incontinence after prolapse surgery.

- Primary Outcome Measures
Name Time Method Prevalence of Bothersome Urinary Incontinence at 12 Months Following Index Surgery 12 months post-surgery Defined as a positive cough stress test or report of bothersome incontinence symptoms.
Number of Participants With Treatment Failure Defined as Subsequent Treatment for Urinary Incontinence, Signs or Symptoms of Bothersome Urinary Incontinence 3 months post-surgery Defined as a positive cough stress test, bothersome incontinence symptoms, or treatment for urinary incontinence, and urinary incontinence (stress, urge, or mixed), regardless of whether interim treatment for incontinence had been provided.
- Secondary Outcome Measures
Name Time Method Medical Outcomes Study 36-Item Short Form Health Survey Baseline, 3 months, and 12 Months post-surgery This survey is a generic health-related quality of life measure. Scores have normalized values with a mean of 50 and a standard deviation of 10, with higher scores indicating better health status. Results measure the average change in scores from baseline to follow-up.
Treatment for Incontinence 3 months post-surgery The need for treatment for any urinary incontinence, including surgery, medication, pessary for incontinence, supervised pelvic-muscle exercises, timed voiding and fluid management, periurethral injection, botulinum toxin injection, neuromodulation, or other treatment for incontinence.
Symptoms of Incontinence 3 and 12 Months Post-surgery Symptoms that were at least moderately bothersome to the participant (as measured by a response of "moderately" or "quite a bit" to any of the four items on the Pelvic Floor Distress Inventory regarding leakage).
Urinary Distress Inventory (UDI) Irritative Symptom Subscale Baseline, 3 months, and 12 months post-surgery Scores on the UDI subscales range from 0 to 100, with higher score indicating more symptoms. Results measure the average change in scores from baseline to follow-up.
Urinary Distress Inventory (UDI) Stress Subscale Baseline, 3 months, and 12 months post-surgery Scores on the UDI subscales range from 0 to 100, with higher score indicating more symptoms. Results measure the average change in scores from baseline to follow-up.
Pelvic Floor Distress Inventory (PFDI) Urinary Distress Inventory (UDI) Baseline, 3 months, and 12 months post-surgery PFDI is a symptom inventory for pelvic floor disorders. Scores ranges from 0 to 300, with higher scores indicating more symptoms. Results measure the average change in scores from baseline to follow-up.
Positive Cough Stress Test 3 and 12 Months Post-surgery A leakage of urine with coughing or straining in either the supine or standing position with the bladder filled through a urethral catheter to 300 ml.
Urinary Distress Inventory (UDI) Obstructive Symptom Subscale Baseline, 3 months, and 12 months post-surgery Scores on the UDI subscales range from 0 to 100, with higher score indicating more symptoms. Results measure the average change in scores from baseline to follow-up.
Incontinence Severity Index Baseline, 3 months, and 12 months post-surgery Scores on the Incontinence Severity Index range from 1 to 12, with higher scores indicating greater severity. Results measure average change in scores from baseline.
