The purpose of the work is to establish and assess the effectiveness of the effect of paravertebral microelectric stimulation of nerve fibers on the possibility of normalizing the tone of the bladder sphincter in neurogenic hypertonicity of the bladder sphincter in dogs that have suffered spinal injuries and have compression damage to the spinal cord.
Dysfunction of the bladder and lower urinary tract is one of the most common complications in spinal cord injuries. When exposed to the traumatic component, compression of the tissues of the spinal cord occurs, which entails a violation of the conductivity of the transmission of nerve impulses in the arc, the central nervous system - the peripheral nervous system, as a result of which there is a violation of the regulation of the act of urination. This pathological condition is called neurogenic bladder, that is, urination disorders (hypotonia or hypertonicity of the bladder or its parts) provoked by diseases of the central and peripheral nervous system.
Hypertonicity of the bladder sphincter causes a delay or complete impossibility of urine drainage if it is impossible to manually drain urine, overfilling and overstretching of the bladder , as a result of which bacterial cystitis, detachment of the bladder mucosa, injuries to the bladder wall may occur. These complications can lead to acute conditions of the animal and even death.
An alternative or auxiliary method for correcting such conditions can be the use of microelectric stimulation of nerve endings in the area of the S1-S3 vertebrae. Electrodes are installed paravertebrally in the sacral spine or at the caudal end of the lumbar spine.For the study, 20 animals with spinal cord compression and bladder hypertonicity were taken,divided equally into experimental and control groups.
During the study, it was found that paravertebral transcutaneous myostimulation has a positive effect on the controlled regulation of bladder function and independent urination.
