RESUMO
Objective To evaluate the effect of electrical stimulation of the pelvic floor muscles combined with bladder training on urinary dysfunctionafter incomplete spinal cord injury.Methods Sixty-two incomplete spinal cord injury patients who had received an operation between November 2009 and December 2014 were enrolled and divided randomly into a control group (n=32) and a treatment group (n =30).Both groups were treated with conventional intermittent catheterization,while the treatment group was additionally given electrical stimulation of the pelvic floor muscles combined with bladder training.The residual urine volume was recorded before and after the treatment.Uurodynamic examinations were conducted,and the rate of successful catheter extraction and of urinary tract infection on the 15th and 30th day of treatment,were recorded and analyzed.Results All of the patients were followed-up for an average of 18.5 months.Significant improvement was observed in the residual urine volume,the maximum or average urinary flow rate,and the detrusor pressure at peak flow of both groups.However,at the end of follow-up the treatment group recorded significantly better results on all these measures than the control group.The successful catheter extraction rate of the treatment group (96.7％) was significantly higher than that of the control group and their average number of catheterization days was significantly fewer.The urinary tract infection rates on the 15th and 30th day of treatment were 16.7％ and 6.7％ in the treatment group,significantly lower than in the control group.Conclusions Electrical stimulation of the pelvic floor combined with bladder training significantly improves urination function after an operation for incomplete spinal cord injury,decreases the days of catheterization and lowers the rate of urinary tract infection.Such combined therapy is worth promoting in clinical practice.
