| One of the causes of urinary retention is a condition called neurogenic bladder. This term refers to a type of bladder malfunction caused by a neurologic disorder or injury. The bladder may empty too frequently, not frequently enough, or in an uncoordinated way. The urinary sphincters may also work incorrectly. The way the bladder and sphincters behave depends on the location of the neurologic disorder in the brain, spinal cord, or peripheral nerves, and the extent of the disease or injury. |

| Types of Neurogenic Bladder Disorders |
| Flaccid or Atonic Bladder |
Occurs after acute spinal cord injury. The bladder fails to contract resulting in urinary retention (inability of the bladder to empty). |
| Spastic or Reflex Bladder |
Occurs when there is a spinal cord injury above the level of S2-S4. It results in frequent uncontrolled voiding due to bladder spasms and a lack of sensation. |
| Uninhibited Bladder |
Urinary frequency and urgency resulting from changes in the brain. This may be caused by conditions such as stroke, head injury or Multiple Sclerosis. |
| Sensorimotor Paralytic Bladder |
Inability to empty the bladder because of damage to the peripheral nervous system. It can be caused by conditions such as diabetes mellitus or extensive pelvic surgery. |
