There are different types of<unk><unk>  depending on the underlying cause. Many of these types may have similar symptoms. Urinary<unk>  and urethra (red) with ureters (green) Uninhibited Uninhibited<unk>  is usually due to damage to the brain from a stroke or brain tumor. This can cause reduced sensation of<unk>  fullness, low capacity<unk>  and urinary incontinence. Unlike other forms of<unk><unk> , it does not lead to high<unk>  pressures that can cause kidney damage. Spastic In spastic<unk><unk>  (also known as upper motor neuron or hyper-reflexive<unk> , the muscle of the<unk>  (detrusor) and urethral sphincter do not work together and are usually tightly contracted at the same time. This phenomenon is also called detrusor external sphincter dyssynergia (DESD). This leads to urinary retention with high pressures in the<unk>  that can damage the kidneys. The<unk>  volume is usually smaller than normal due to increased muscle tone in the<unk> . Spastic<unk><unk>  is usually caused by damage to the spinal cord above the level of the 10th thoracic vertebrae (T10). Flaccid In flaccid<unk>  (also known as lower motor neuron or hypotonic<unk> , the muscles of the<unk>  lose ability to contract normally. This can cause the inability to void urine even if the<unk>  is full and cause a large<unk>  capacity. The internal urinary sphincter can contract normally, however urinary incontinence is common. This type of<unk><unk>  is caused by damage to the peripheral nerves that travel from the spinal cord to the<unk> . Mixed Mixed type of<unk><unk>  can cause a combination of the above presentations. In mixed type A, the<unk>  muscle is flaccid but the sphincter is overactive. This creates a large, low pressure<unk>  and inability to void, but does not carry as much risk for kidney damage as a spastic<unk> . Mixed type B is characterized by a flaccid external sphincter and a spastic<unk>  causing problems with incontinence.
