About this study

Official title: Better Short-Term Outcomes With The 'U-Method' Compared to the 'Hammock' Technique for the Implantation of the TVT-SECUR Under Local Anesthesia

The objective was to observe the satisfaction of local anesthesia during the implantation of the TVT-SECUR for the treatment of stress urinary incontinence, with the use of questionnaires completed by the patients, and to evaluate the short-term efficacy and safety of the sling, with a comparison of the two techniques of implantation: the 'U-Method' and the 'Hammock' technique.

Read the detailed description

Stress urinary incontinence (SUI) is a common problem, affecting women of all ages. Treatment options for SUI include physiotherapy and surgical interventions, such as retropubic operations and midurethral slings. Conventional retropubic and transobturator tapes are the preferred choice for most surgeons, because of their wide applicability, technical simplicity and clinical efficacy. The retropubic tape has been effective for many years, but exposes the patients to serious complications, such as bladder perforations, principally because of the use of the retropubic space for the fixation of the tape. In an attempt to avoid the retropubic space, the second generation of slings, the transobturator tape, was introduced. However, prolonged postoperative groin pain as well as vascular injuries have been reported.

The last generation of midurethral slings, the tension-free vaginal tape system (TVT-SecurTM, Gynecare, Ethicon, Somerville, NJ, USA), introduced in 2005, attempts to lower the number of complications, by involving only a small vaginal incision and no exit wound. This 8-cm long laser-cut polypropylene mesh can potentially be implanted under local anesthesia, because of a less-invasive technique using minimal vaginal dissection as well as avoidance of retropubic space and obturator fossa. In the case of conventional midurethral slings, even if their implantation under local anesthesia has been studied and proven relatively safe, this practice has not gained popularity.

This was a prospective, clinical study with primary objective to observe the satisfaction of local anesthesia during the implantation of the TVT-SECUR, with the use of questionnaires completed by the patients. The secondary objective was to observe the short-term efficacy and safety of the sling. The final objective was to compare the two techniques of implantation: the 'U-Method' and the 'Hammock' technique.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TVT-SECUR - 'Hammock' techniqueProcedure or surgery

    The surgery was done under local anesthesia by one high-volume surgeon. The 'Hammock' technique, similar to the transobturator tape dissection, was used in the first 23 cases and the 'U-Method', similar to the retropubic tape dissection, in the last 25 cases. Interim analysis performed after 23 cases led us to change the technique to the 'U-Method'.

  • TVT-SECUR - 'U-Method'Procedure or surgery

    The surgery was done under local anesthesia by one high-volume surgeon. The 'Hammock' technique, similar to the transobturator tape dissection, was used in the first 23 cases and the 'U-Method', similar to the retropubic tape dissection, in the last 25 cases. Interim analysis performed after 23 cases led us to change the technique to the 'U-Method'.

  • Local anesthesia (30 to 40 ml of a mixture of 35 ml of lidocaine 2% and 5 ml of bicarbonate 3%).Drug

    Local anesthesia consisted of 30 to 40 ml of a mixture of 35 ml of lidocaine 2% and 5 ml of bicarbonate 3%. Sedation was used in association with local anesthesia, including 1 mg of lorazepam sublingual as well as a combination of 0.5 to 2 mg intravenous (IV) of midazolam and 50 to 200 ug IV of fentanyl. Postoperative analgesia consisted of a prescription of 30 tablets of morphine 5 mg.

TVT-SECURExperimentalThis study arm consisted of 48 women operated from January 2007 to October 2008. All patients underwent the implantation of the TVT-SECUR for the treatment of stress urinary incontinence or stress predominant mixed urinary incontinence. The surgery was done under local anesthesia by one high-volume surgeon.
Receives: Procedure: TVT-SECUR - 'Hammock' technique; Procedure: TVT-SECUR - 'U-Method'; Drug: Local anesthesia (30 to 40 ml of a mixture of 35 ml of lidocaine 2% and 5 ml of bicarbonate 3%).

What is being measured

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

  1. Local Anesthesia Satisfaction

    Local anesthesia satisfaction was assessed with a questionnaire completed by the patients. The patients were asked if they would recommend this type of anesthesia (yes or no).

    Measured: Questionnaire filled 1 week after surgery

Secondary outcomes (2)
  1. Improvement in Stress Urinary Symptoms.

    A questionnaire with a Likert scale from one to five was used to assess the improvement in stress urinary symptoms at six months for each technique, the 'Hammock' technique and the 'U-Method' (1-Worst, 2-Same, 3-Improved, 4-Almost cured, 5-Cured). Patients had to answer 3 or more on the scale to be considered improved.

    Measured: Six months

  2. Safety of the Sling.

    Safety of the sling was assessed with a record of perioperative and postoperative complications. The following are all the complications experienced with the TVT-SECUR for each technique, the 'Hammock' technique and the 'U-Method'.

    Measured: 15 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TVT-SECUR - 'Hammock' technique, TVT-SECUR - 'U-Method' and Local anesthesia (30 to 40 ml of a mixture of 35 ml of lidocaine 2% and 5 ml of bicarbonate 3%). in people with Urinary Stress Incontinence, run by Université de Sherbrooke at 1 site in Canada.

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 2 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 May 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 May 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Local Anesthesia Satisfaction (time frame: Questionnaire filled 1 week after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2009.
