Neurogenic bladder is a urinary problem in which there is abnormal emptying of the bladder with subsequent retention or incontinence of urine. Depending on the type of neurological disorder causing the problem, the bladder may empty spontaneously (incontinence) or may not empty at all (retention with overflow leakage).

Some of the common causes for neurogenic bladder are nervous system tumor, trauma, neuropathy, or inflammatory conditions (such as multiple sclerosis).
