The spinal cord is the channel that connects the central nerves to the peripheral nerves and is a key link in transmitting commands from the brain to all parts of the human body. A spinal cord injury is usually the result of an external blow to the spine that causes a vertebral fracture, resulting in damage to the spinal cord. It can also be a consequence of diseases such as myelitis, spinal cord tumors, and spinal cord vascular lesions. The main dysfunctions of spinal cord injury include: 1, paralysis: injuries to the thorax and waist lead to paralysis of the lower extremities, and injuries to the neck can lead to quadriplegia. 2, sensory impairment: paralyzed limbs are usually accompanied by corresponding sensory impairment, or even loss. Urinary and fecal incontinence: urinary incontinence is very common, and there is often difficulty in urination. The stool is usually constipated and can also be incontinent. 4.Pain: Many patients have pain below the injury site. 5, muscle spasm: spinal cord injuries above the waist often appear muscle spasm, affecting limb movement, care, and sometimes can cause pain. 6, pressure sores (bedsores) is the most common complications of spinal cord injury, which can lead to infection and activity disorders. 7, psychological disorders. Most patients have varying degrees of psychological disorders, and this aggravates the condition. 8, other: infection, autonomic dysregulation, heterotopic ossification, breathing difficulties, etc. Neurogenic bladder is a common complication of spinal cord injury, which refers to urinary dysfunction caused by central and peripheral nerve disorders. Normal voiding depends on contraction of the bladder forcing muscles and relaxation of the sphincter muscles, which are coordinated with each other. The clinical manifestations of neurogenic bladder are voiding dysfunction, including: ① motor disorders cum reflex incontinence, urge incontinence, stress incontinence; ② sensory disorders cum urinary frequency, urgency, bladder filling sensation with varying degrees of relief after urination. Abnormalities in urination after spinal cord injury should be promptly seen at a specialist outpatient clinic and, if necessary, require inpatient examination and treatment. Routine examination can exclude urinary stones and infections, while invasive examination refers to cystography, urodynamic examination and cystoscopy, etc., which can further understand the type of urinary disorder and then take corresponding treatment measures. The methods of treatment of urinary disorders after spinal cord injury in Chinese hospitals include: acupuncture, rehabilitation physiotherapy, internal administration of Chinese herbs, guidance of abdominal pressure urination, intermittent clean catheterization, forced urinary muscle reflex hyperactivity can be taken to forced urinary muscle toxin injection, low compliant bladder feasible bladder enlargement surgery, if the physical condition is poor and unable to take care of themselves, suprapubic cystotomy and fistula is needed.
