N31: Neuromuscular dysfunction of bladder, not elsewhere classified

N31.2: Flaccid neuropathic bladder, not elsewhere classified

The bladder is like a balloon. There is a hollow space on the inside. This hollow space is surrounded by the bladder wall. There is a muscle in the bladder wall. When the muscle in the bladder wall contracts, the urine is squeezed out of the bladder and out of the body.

The muscle in the bladder wall is controlled by nerves. Many nerves run from the spinal cord and brain to the organs, skin and muscles in the body. If the nerves, brain or spinal cord are damaged, the muscle in the bladder can no longer work properly. Nerves, brain and spinal cord can be damaged, for example, by other conditions or following surgery.

The muscle in your bladder wall is not working sufficiently. This may mean you are no longer able to urinate properly. In that case there is often some urine left in your bladder.
