Novel Surgical Technique for the Treatment of Female Stress Urinary Incontinence: Transobturator Vaginal Tape Inside-Out

A three-year follow up of tension free vaginal tape for surgical treatment of female stress urinary incontinence

Background Midurethral slings are increasingly used for the treatment of stress incontinence, but there are limited data comparing types of slings and associated complications. Methods We performed a multicenter, randomized equivalence trial comparing outcomes with retropubic and transobturator midurethral slings in women with stress incontinence. The primary outcome was treatment success at 12 months according to both objective criteria (a negative stress test, a negative pad test, and no retreatment) and subjective criteria (self-reported absence of symptoms, no leakage episodes recorded, and no retreatment). The predetermined equivalence margin was ±12 percentage points. Results A total of 597 women were randomly assigned to a study group; 565 (94.6%) completed the 12-month assessment. The rates of objectively assessed treatment success were 80.8% in the retropubic-sling group and 77.7% in the transobturator-sling group (3.0 percentage-point difference; 95% confidence interval [CI], −3.6 to 9.6). The r...

Retropubic versus Transobturator Midurethral Slings for Stress Incontinence

In a prospective long-term Nordic multicenter study, 90 consecutive patients who had a tension-free vaginal tape (TVT) operation performed because of stress urinary incontinence were evaluated according to a strict protocol after approximately 5 years (range 48–70 months). Eighty-five patients could be evaluated according to the protocol. Another 5 elderly patients had to be interviewed by telephone at the final check-up after 5 years. The study protocol involved pre- and postoperative objective and subjective evaluation. The median follow-up time was 56 months. Seventy-two of the 85 patients who were fully evaluated (84.7%) were both objectively and subjectively completely cured. Another 9 patients (10.6%) were significantly improved and 4 (4.7%) were regarded as failures. No patient complained of long-term voiding difficulties and there were no signs of defective healing or rejection of the tape material. All patients had suffered from primary stress incontinence, and 25 also had preoperative complaints of urge. In 14 of these (56%) the urge symptoms were relieved postoperatively. We conclude that the TVT procedure seems to fulfil the expectations of high long-term cure rates, as suggested in previous short-term reports.

Long-term results of the tension-free vaginal tape (TVT) procedure for surgical treatment of female stress urinary incontinence.

The aim of the study was to evaluate the safety and efficacy of TVT (tension-free vaginal tape) for the surgical treatment of stress urinary incontinence. The design was a prospective open multicenter study including six centers, each operating an approximately 20 patients. In total 131 patients suffering from genuine stress incontinence were included. They were followed for at least 1 year using a specific protocol for objective and subjective evaluation of the outcome. All patients underwent the operation under local anesthesia. Mean operation time was 28 minutes (range 19–41 minutes); 119 (91%) of the patients were cured according to the protocol and another 9 (7%) were significantly improved. There were 3 (2%) failures. The majority of the patients (about 90%) were operated upon on a day-care basis, which implied that they were released from the hospital within 24 hours, with no postoperative catheterization. No defect healing and no tape rejection occurred. Three patients needed an indwelling catheter for 3 days. In 1 patient catheterization was necessary for more than 10 days. Two uncomplicated hematomas and one uncomplicated bladder perforation occurred. Based on the results, we conclude that TVT is a safe and effective ambulatory procedure for surgical treatment of genuine stress urinary incontinence.

A multicenter study of tension-free vaginal tape (TVT) for surgical treatment of stress urinary incontinence

The object was to study prospectively the results of a modified intravaginal slingplasty for the surgical treatment of female stress incontinence, carried out under local anesthesia as a day procedure. Seventy five patients with genuine stress incontinence were operated upon and followed for a 2-year period. All patients were diagnosed urodynamically to have genuine stress incontinence. Pad tests and quality of life assessments were carried out in all patients both pre- and postoperatively. There were no intra- or postoperative complications and 63 patients (84%) were completely cured throughout the 2-year follow-up period. Six patients (8%) were significantly improved, i.e. they did not loose urine apart from an occasional leakage during severe cold etc. In the remaining 6 patients (8%) no improvement was seen. These failures were obvious at the first postoperative check-up after 2 months. Thus, there were no relapses after 2 months. All but 5 patients were able to void properly directly after surgery. These 5 needed an indwelling catheter during the night directly after the operation. All 75 patients were released from the hospital the same day or the day after surgery without catheterization. Mean sick leave was 10 days and mean operation time 22 minutes. No defect healing or rejection of the sling occurred. It is concluded that the procedure described is a promising new technique for the surgical treatment of female stress incontinence. Prospective long-term studies including more patients are in progress to establish the definitive place of this technique in the clinical routine.
