A review of the tension-free vaginal tape procedure: outcomes, complications, and theories

Abstract

In the last century, the pathophysiology of stress urinary incontinence (SUI) has been investigated and several surgical techniques have been utilized for cure. The most recent evolution in the study of SUI is the minimally invasive tension-free vaginal tape (TVT) procedure, which can be done under local anesthesia and intravenous sedation and is individualized for each patient. The procedure recreates the "hammock" of the anterior vaginal wall and endopelvic fascia with a mesh tape of polypropylene. The cure rates of the initial studies are equal to or better than other anti-incontinence procedures, and the permanent supportive mesh is very well tolerated. The TVT creates a backboard on which the urethra compresses itself when it rotates posteriorly during cough or stress. The procedure accomplishes subjective and objective cure without elevating the bladder neck or altering urethral mobility.
