Study summary

This study will assess the feasibility and success of performing the SolyxTM SIMUS in the office using the Dynamic Interactive Standing Sling Technique (DISSTTM). Study endpoints will be feasibility, composite success, complications, and patient and physician acceptance.

Read the detailed description

The single-incision midurethral sling (SIMUS) is a procedure where there are no exit incisions. There is a 15 mm suburethral incision with the sling being attached with anchors to the obturator muscle on each side. This procedure has potentially lesser side-effects compared to the longer slings however, the literature has not found the SIMUS to be as effective as the long slings. In our recently published study, the DISSTTM technique has significantly improved the success of the SIMUS procedure as the sling can be tested for proper application in vivo.

As we have performed several of these procedures in the operating room entirely under local anesthesia, we have decided to perform this procedure in an office setting using the same safety precautions as in a hospital operating room.

Performing this procedure in the office has significant benefits for the patient, the healthcare industry, and the economy overall. Moving away from a hospital setting has significant psychological benefits. This will increase patient acceptance and therefore will become appealing to many more women who may be shying away from treatment.

It would also eliminate the risk of nosocomial infections for the patient and family members, improve efficiency as the wait time would be negligible, and would reduce the expense of the entire treatment as hospital costs would not feature in the equation.

This study will assess the feasibility and success of performing the SolyxTM SIMUS in the office using the Dynamic Interactive Standing Sling Technique (DISSTTM). Study endpoints will be feasibility, composite success, complications, and patient and physician acceptance.

What researchers measure

Primary outcomes

  1. Subject tolerability of the Solyx SIMUS in the office using the Dynamic Interactive Standing Sling Technique (DISST)

    Subject tolerability will be assessed using a 10-cm Visual Analogue Scale rating tolerability of the procedure. The Visual Analog Scale measures discomfort of the procedure with 0 being no discomfort and 10 being severe discomfort.

    Time frame: intraoperative

  2. Surgeon difficulty of performing the Solyx SIMUS in the office using the Dynamic Interactive Standing Sling Technique (DISST)

    Surgeon difficulty will be determined by a 5-point Likert scale ranging from 1 (very easy) to 5 (very difficult).

    Time frame: intraoperative

  3. Ability to achieve DISST SUCCESS

    Defined as a negative intraoperative standing cough stress test (CST) at bladder fullness.

    Time frame: intraoperative

  4. Complications of performing the Solyx SIMUS in the office using the Dynamic Interactive Standing Sling Technique (DISST)

    Any intraoperative complications will be documented

    Time frame: intraoperative

Secondary outcomes

  1. Improvement in overall urinary incontinence (stress and urge incontinence)

    Subject will complete the Medical, Epidemiologic, and Social Aspects of Aging (MESA) urinary incontinence questionnaire to assess improvement in urge incontinence and stress incontinence. Subjects will also complete the Patient Global Impression of Improvement (PGI-I) questionnaire as it pertains to stress urinary incontinence.

    Time frame: 3, 6, 12, 24 and 60 months post operative

  2. Sexual function

    Subject will complete the Pelvic Organ Prolapse/Urinary Incontinence Sexual (PISQ-12) questionnaire to assess changes in sexual function.

    Time frame: 3, 6,12, 24 and 60 months post operative

  3. Improvement in patient quality of life as it relates to urinary symptoms

    Subject will complete Incontinence Impact Questionnaire (IIQ-7) to assess changes in quality of life related to urinary symptoms.

    Time frame: 3, 6,12, 24 and 60 months post operative

  4. Subject satisfaction with overall improvement from sling procedure

    Subject will completed satisfaction questionnaire to determine patients overall satisfaction with the procedure and results

    Time frame: 3, 6, 12, 24 and 60 months post operative

  5. Post operative pain

    Post operative pain will be assessed using a McCarthy pain scale questionnaire, which ranges from "No Pain Sensation" to "Most Intense Pain Sensation Imaginable". Pain will be assessed at rest, during daily activities, during sex, lifting, or other strenuous work in the last 24 hours. This will be completed prior to surgery, the day of, and the 7 days following surgery.

    Time frame: pre-procedure to 7 days after procedure

  6. Post operative complications

    At post operative visits patients will be asked and assessed for post operative complications (based upon the Clavien Dindo classification)

    Time frame: post procedure to 12, 24 and 60 months

  7. Return to pre-surgical activities

    Patients will be asked what activities they engage in prior to surgery including work, exercise, social, and household activities. At each post operative visit the patient will be asked when they returned to pre-surgical activities.

    Time frame: Pre-procedure to return to 60 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2019 to primary completion in Mar 2020, 9 months.

Of 226 non-industry interventional studies with no phase under Urinary Incontinence, Stress, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 9 months is below that.

Counting every sponsor, half of 267 studies reached it within 19 months; a quarter within 9 and three quarters within 43.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
