Minimally invasive management of urinary incontinence

Stress urinary incontinence is defined as the loss of urine at the time of an increase in abdominal pressure in the absence of a detrusor contraction. A nearly 50% prevalence of urinary incontinence in women and estimated treatment costs of more than 10 billion US dollars annually in the United States warrant an effective, successful and minimally invasive treatment. Nearly 200 different operations have been described in the literature, with cure rates reported ranging from 40% to 95%, clearly suggesting that the optimal surgical procedure has yet to be developed. Genuine stress urinary incontinence can result from either hypermobility of the bladder neck and proximal urethra or intrinsic sphincteric deficiency, which may occur alone or in combination with anatomic defects. In reviewing the recent literature and surgical modalities we present our opinion on minimally invasive surgical management of urinary incontinence.
