leakage). Wet variants are more common than dry variants. The distinction is not absolute; one study suggested that many classified as "dry" were actually "wet" and that people with no history of any leakage may have had other syndromes. OAB is distinct from stress urinary incontinence, but when they occur together, the condition is usually known as mixed incontinence. Management A recent (2019) systematic review of studies related to urinary incontinence in women found that behavioral therapy, alone or combined with other treatments, is generally more effective than any other single treatment alone. Behavioral therapy as a treatment has been used to improve or cure urgency urinary incontinence, including improving patient satisfaction. Lifestyle Treatment for OAB includes nonpharmacologic methods such as lifestyle modification (fluid restriction, avoidance of caffeine), bladder retraining, and pelvic floor muscle (PFM) exercise. Timed voiding is a form of bladder training that uses biofeedback to reduce the frequency of accidents resulting from poor bladder control. This method is aimed at improving the person's control over the time, place and frequency of urination. Timed voiding programs involve establishing a schedule for urination. To do this, a person fills in a chart of voiding and leaking. From the patterns that appear in the chart, the person can plan to empty his or her bladder before he or she would otherwise leak. Some individuals find it helpful to use a vibrating reminder watch to help them remember to use the bathroom. Vibrating watches can be set to go off at certain intervals or at specific times throughout the day, depending on the watch. Through this bladder training exercise, the person can alter their bladder's schedule for storing and emptying urine. Medications A number of antimuscarinic drugs (e.g., darifenacin, hyoscyamine, oxybutynin, tolterodine, solifenacin, trospium, fesoterodine) are frequently used to treat overactive bladder. Long term use, however, has been linked to dementia. β3 adrenergic receptor agonists (e.g., mirabegron, vibegron), may be used, as well. However, both antimuscarinic drugs and β3 adrenergic receptor agonists constitute a second-line treatment due to the risk of side effects. Few people get complete relief with medications and all medications are no more than moderately effective. A typical person with overactive bladder may urinate 12 times per day. Medication may reduce this number by 2-3 and reduce urinary incontinence events by 1-2 per day. Procedures Various devices (Urgent PC Neuromodulation System) may also be used. Botulinum toxin A
