Abstract
There is a direct continuation between bladder and urethral musculature. The external sphincter consists of circular, striated muscle fibers, while the smooth ‘internal’ sphincter does not form a real ring, however, this sphincteric part, under resting conditions, maintains continence, which is demonstrated by an example. Smooth sphincteric insufficiency, too, is observed during general weakness of the pelvic floor, the symptom can be nocturnal incontinence, when the supporting help of the external sphincter is abolished. The voluntary sphincter is needed to maintain continence during stress and to stop the flow abruptly.
