A prospective randomized controlled trial of the transobturator tape and tissue fixation system minisling in 80 patient with stress urinary incontinence - 3 year results

In 1990 Petros & Ulmsten described a prototype intravaginal slingplasty operation, later known as the “TVT”, which was based on their “Integral Theory”1. A Mersilene tape was inserted below the midurethra, exiting unattached through the lower abdominal muscles. Post-operative xrays demonstrated no change in the position of bladder neck in patients cured of their SI, thereby invalidating the pressure transmission theory2. This method was revolutionary in that it was a minimally invasive day-care operation, with
