Neurogenic bladder, as the name implies, is a disease that is closely related to the function of the bladder due to neurological causes, but it is not only this, it actually refers to the abnormal function of the bladder and urethra due to neurological causes. It is not only the abnormal function of the bladder and urethra themselves, but also the abnormal coordination between the two due to neurological factors. Neurological factors include not only disorders of the central nervous system and peripheral nervous system itself, but also other systems of the body that affect the nervous system, thus affecting urination. For example, frequent and difficult urination caused by stroke, urinary incontinence caused by spinal cord injury, and difficulty in urination caused by diabetes and pelvic surgery.
