Background The urinary bladder is a viscoelastic hollow organ, whose function consists in collecting and storing the produced amounts of urine to allow urinary voiding in bigger amounts and longer intervals. Bladder closure during the ordinary non-voiding condition is ensured via the tonus of the functional urethra. Four nerval control circuits (coming from the cortex, over the brain stem and the sacral micturition center, up to the urinary bladder), have been described by Bradley et al. (1976) which are responsible for the activation and coordination of the micturition reflex. For urinary continence to be maintained, urethral pressure must be greater than bladder pressure at all times. The rise in urethral pressure before the increase in intra abdominal pressure (IAP) during a cough indicates that factors other than IAP are responsible for...
