A loss of urinary control. There are various kinds and degrees of incontinence. Overflow incontinence is a condition in which the bladder retain urine after voiding. As a consequence, the bladder remains full most of the time, resulting in involuntary seepage of urine from the bladder. Stress incontinence is the involuntary discharge of urine when there is increased pressure upon the bladder, as in coughing or straining to lift heavy objects. Total incontinence is the failure of ability to voluntarily exercise control over the sphincters of the bladder neck and urethra, resulting in total loss of retentive ability.
