Safety and Efficacy Study on the Implantation of the Tension-Free Vaginal Tape (TVT-Secur) Under Local Anesthesia

2014-08-27 03:22:02 | BioPortfolio


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.


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.

Medical and Biotech [MESH] Definitions

A local anesthetic of the amide type now generally used for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1006)

A technique using a pneumatic, high-pressure stream of aluminum oxide to remove DENTAL ENAMEL; DENTIN; and restorative materials from teeth. In contrast to using DENTAL HIGH-SPEED EQUIPMENT, this method usually requires no dental anesthesia (ANESTHESIA, DENTAL) and reduces risks of tooth chipping and microfracturing. It is used primarily for routine DENTAL CAVITY PREPARATION.

Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.

Procedure in which an anesthetic such as a gas or mixture of gases is inhaled through a tube into the lungs.
