Urinary symptoms such as frequency, urgency, nocturia, and incontinence occur in many women. Overactive bladder (OAB) accounts for forty to seventy percent of urinary incontinence. These symptoms can be mildly annoying to life altering. Many women wear pads or adult diapers daily and avoid social situations for fear of embarrassment. It is felt that up to sixteen percent of the adult population may suffer from these symptoms and many of these women seek medical help.
