Neurogenic Bladder
The muscles and nerves of the urinary system work together to hold urine in the bladder and then release it at the appropriate time. Nerves carry messages from the bladder to the brain and from the brain to the muscles of the bladder telling them either to tighten or release. In a neurogenic bladder, the nerves that are supposed to carry these messages do not work properly.
