About this study

Official title: A Randomized Study of the Treatment of Urodynamic Stress Incontinence: the Tension Free Vaginal Tape (TVT) Versus the Miniarc Sling.

The aim of this study is to assess whether the Miniarc suburethral sling is equivalent to the TVT in the treatment of women with urodynamic stress incontinence (USI). If equivalence is proven, the advantages to women with USI will be potentially significant since the Miniarc may be carried out as an office based procedure, negating the need for an anaesthetic and hospital admission. The investigators null hypothesis is that there is no difference in subjective or objective outcome between the TVT and the Miniarc in the treatment of USI.

Eligible women will be initially assessed with a full history and examination, King's Health Questionnaire and twin channel subtraction cystometry. They will be randomised (using a series of numbered opaque envelopes) to undergo either the TVT or Miniarc. Follow up will be at 6 weeks, with a subjective outcome measure and at 6 months with a repeat subjective assessment and repeat twin channel cystometry.

Read the detailed description

Description Randomised, prospective study. Objective and subjective outcomes to be evaluated 6 weeks an d6 months post-operatively.

Study population The number of patients enrolled in the study will be decided after consultation with a statistician.

All patients will be recruited from urogynaecology clinics at Medway Maritime Hospital. They will be female and have a urodynamic diagnosis of stress incontinence, having failed conservative management. Those deemed suitable for the TVT operation will be offered entry to the study.

Randomisation and blinding

Patients who have consented to take part in the study will be randomised to have either a conventional TVT (Group A) or a MiniArc (Group B). Each group will be run in parallel. Method of randomisation - consecutively numbered opaque envelopes detailing type of operation.

Patients will be blinded as to the type of tape used. Due to the obvious differences between the devices, it will not be possible to blind researchers to the type of tape.

Each patient will undergo a pre-operative assessment (which may be incorporated into the initial clinic visit), be admitted as an in-patient for the TVT/Mini-arc procedure, and attend a post-operative assessment visit. This last visit will be the exit point from the study. These are detailed below

Pre-operative Assessment

  1. Detailed symptom history and examination
  2. 3 day urinary diary
  3. King's Quality of Life questionnaire
  4. Dual channel normal saline subtracted cystometry at a filling rate of 50-100ml/min whilst supine and standing. 7F double lumen catheter used for all measurements

Surgical Technique

Group A will have the TVT inserted under spinal anaesthesia as described by Ulmsten12. Group B will have the MiniArc tape inserted under spinal anaesthesia. All procedures will be undertaken in an operating theatre environment, and carried out by Mr Duckett or a member of his team who has undergone appropriate training. Patients will be catheterised until 6 hours post-operatively. Those who void with a residual of less than 100mls will be discharged the day after the procedure.

Post-operative assessment

  1. Carried out at 6 weeks' post-operatively
  2. Symptoms assessed using 3 day urinary diary and Patient Global Impression of Improvement (PGI-I)
  3. King's quality of life questionnaire
  4. Repeat urodynamic studies as described previously, including voiding cystometry (6 months only)
  5. Any complications noted, e.g. readmission to hospital, UTI, voiding difficulties
  6. Patient satisfaction will be assessed using a 5 point scale at the follow up visit

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The absence of stress incontinence at 6 weeks ascertained by direct questioning and from the Kings Quality of life questionnaire and the absence at 6 months by the same criteria and by urodynamics.

    Measured: 6 weeks and 6 months

Secondary outcomes (3)
  1. Quality of life (as measured using the King's Health Questionnaire)

    Measured: 6 weeks and 6 months

  2. Intra-operative complications, e.g. bladder injury

    Measured: Time of surgery

  3. Post-operative voiding dysfunction

    Measured: 0-6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Tension Free Vaginal Tape and Miniarc in people with Urodynamic Stress Incontinence, run by Medway NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The absence of stress incontinence at 6 weeks ascertained by direct questioning and from the Kings Quality of life questionnaire and the absence at 6 months by the same criteria and by urodynamics. (time frame: 6 weeks and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00843908, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
