Abstract：Objective To investigate the effects of low-frequency electronic pulse therapy on urinary frequency and urinary tract infection in patients with neurogenic bladder urinary retention after spinal cord injury(SCI).Methods Between March 2021 and April 2024,83 SCI patients with neurogenic bladder complications were enrolled from the First Affiliated Hospital of Zhengzhou University and randomly allocated to a control group(41 patients)and an observation group(42 patients).The control group received standard care and bladder rehabilitation exercises plus conventional intermittent catheterization,while the observation group received additional low-frequency electrical pulse therapy.Treatment outcomes,voiding patterns,urodynamic parameters,and urinary infection rates were analyzed and compared between both groups.Results After the treatment,the total clinical effective rate of the observation group[95.24％(40/42)]was better than that of the control group[78.05％(32/41)](P＜0.05).Compared with before treatment,the average daily single urine output,detrusor systolic pressure and urine flow rate of patients in both groups increased after treatment(P＜0.05),and the improvement in the observation group was more significant(P＜0.05).Meanwhile,the daily frequency of urination,frequency of urinary leakage,residual urine volume in the bladder and intravesical pressure in both groups decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was greater(P＜0.05).The incidence of urinary tract infection in the observation group[4.76％(2/42)]was lower than that in the control group[21.96％(9/41)](P＜0.05).Conclusion Low-frequency electronic pulse therapy can significantly improve the clinical symptoms of patients with neurogenic bladder urinary retention after SCI,optimize urodynamic parameters,reduce the risk of urinary tract infection,and contribute to the recovery of bladder function.
