March 6, 2024 updated by: Prof. Dr. Volker Viereck, Cantonal Hospital, Frauenfeld

Prospective, Observational Study: Can Pelvic Floor Ultrasound Help to Optimize TOT (Transobturator Tape) Positioning?

This is a prospective, observational, multicenter study of women with surgically-correctable stress urinary incontinence who undergo a TOT-sling operative procedure.

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.

Detailed Description

This is a prospective, observational, multicenter study of women with surgically-correctable stress urinary incontinence who undergo a TOT-sling operative procedure. Data will be collected from preoperative urogynecological testing and medical histories. Outcome data will be collected 1-3 days and 6 months after procedure.

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

Sampling Method

Probability Sample

Study Population

The study population includes women with surgically-corrected stress urinary incontinence who undergo a TOT operative procedure.

Description

Inclusion Criteria:

  1. Patient has objective demonstrable signs of stress urinary incontinence (SUI), including patients with intrinsic sphincter deficiency (ISD). Objective testing includes: standing stress test, urodynamics evaluation, or pad test.
  2. Patient is age 18 or older.
  3. Patient agrees to participate in the study, including completion of all study-related procedures and evaluations, and documents this agreement by signing the Institutional Review Board (IRB)/Ethic commission (EC)-approved informed consent.
  4. Patient is able to fill in all questionnaires (on judgement of investigator)

Exclusion Criteria:

  1. Patient has an associated or suspected neurological disease.
  2. Patient has an active lesion or present injury to perineum or urethra.
  3. Patient has a urethral obstruction.
  4. Patient has significant pelvic organ prolapse (Grade III/IV) requiring surgical treatment.
  5. Patient currently has an urinary tract infection.

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
Cure rate
Time Frame: 6 months postoperative
The primary outcome of the TOT procedure will be assessed using a combination of objective and subjective criteria. Patients with a negative stress test, a negative 1-h pad test (less than 2 g) and the degree of subjective suffering improving to over 90% (VAS score of 0-1) at 6 months follow-up evaluation are classified as cured. All other patients are classified as treatment failure even if one aspect shows marked improvement from the preoperative condition.
6 months postoperative

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
Urethral length
Time Frame: Preoperative
Urethral length will be measured by pelvic floor sonography.
Preoperative
Linear urethral dorsocaudal movement (LUDM)
Time Frame: Preoperative
Linear urethral dorsocaudal movement (LUDM) will be assessed by pelvic floor sonography.
Preoperative
Urethral tape position
Time Frame: 1-3 days and 6 months postoperative
The position of the TOT along the urethra will be determined by pelvic floor sonography and expressed as percentage of urethral length.
1-3 days and 6 months postoperative
Distance between tape and longitudinal smooth muscle (LSM) complex
Time Frame: 1-3 days and 6 months postoperative
To characterize the location of the TOT, the shortest distance between the tape and the longitudinal smooth muscle (LSM) complex of the urethra will be measured by pelvic floor sonography.
1-3 days and 6 months postoperative
Urodynamic testing
Time Frame: Preoperative
Urodynamic testing will be performed only for patients undergoing recurrent incontinence surgery.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
