Therapeutic Effect Of Sacral Nerve Stimulation On Neurogenic Bladder After Spinal Cord Injury

Objective: To study the effect and mechanism of magnetic stimulation on S3 nerve roots in patients with spinal cord injury and neurogenic bladder.Methods: Thirty patients with eligible spinal neurogenic bladder were randomly divided into magnetic stimulation group and control group.The magnetic stimulation group was also treated with sacral nerve root magnetic stimulation on the basis of conventional treatment.The control group only received basic treatment.The two groups were treated for 4 weeks.Before and after treatment,the patients were treated with urine routine to determine urodynamics and quality of life scores after no urinary tract infection.The records included urodynamic examination items(primary bladder sensation,maximum bladder volume at the end of filling,residual urine volume,maximum intravesical pressure during urination,maximal urinary closure pressure,etc.)and quality of life scores due to urinary symptoms.Results: Initial bladder sensation: The initial sensation of bladder was decreased after treatment in the magnetic stimulation group(P<0.05).There was no significant change in the control group before and after treatment(P>0.05).The initial sensation of bladder after sacral nerve stimulation was not accepted.The change in the treated patients was more significant(P < 0.05).Maximum bladder capacity: The maximum bladder volume increased after magnetic stimulation group and control group(P<0.05).There was no significant difference between the two groups before and after treatment(P>0.05).Residual urine volume: The residual urine volume of the magnetic stimulation group and the control group decreased after treatment(P<0.05),and the residual urine volume of the patients after the sacral nerve stimulation treatment was more significant than that of the patients who did not receive the treatment(P<0.05).Maximum intravesical pressure: The maximum intravesical pressure increased after magnetic stimulation group and control group(P<0.05).There was no statistically significant difference between the two groups before and after treatment(P>0.05).Maximum urinary tract closure pressure: The maximum occlusion pressure of the urethra increased after magnetic stimulation group and control group(P<0.05).The maximum urinary closure pressure of patients after sacralnerve stimulation was more significant than that of patients who did not receive this treatment(P<0.05).).The quality of life scores in the magnetic stimulation group decreased after treatment(P<0.05).There was no statistically significant difference between the two groups before and after treatment(P>0.5).There was no statistically significant difference between the two groups before and after treatment.>0.05).Conclusion: This study shows that sacral nerve root stimulation can improve neurogenic bladder urine retention after spinal cord injury.
