Abstract: Objective To observe the effect of electrical stimulation combined with bladder function training on autonomic bladder patients after S_2-4 spinal cord injury or cauda equina and pelvic nerve injury. Methods From January, 2016 to August, 2017, 76 patients with autonomic bladder after spinal cord injury were divided into control group (n=29) and observation groups (n=47) in real world study. The control group received routine bladder function training, and the observation group received bladder muscle stimulation therapy in addition. The micturition diary and urodynamic indexes were assessed before and three months after treatment. Results After treatment, the frequency of urinary incontinence and the number of micturition in 24 hours, and residual urine volume significantly reduced (t>3.251, P<0.01), the urine output every time significantly increased (t>5.000, P<0.001), the maximum bladder capacity and urine flow rate increased (t>1.922, P<0.05), and the detrusor pressure in the end of filling period significantly reduced (t>8.302, P<0.001). All the indexes above were better in the observation group than in the control group (t>1.919, P<0.05). Conclusion Electrical muscular stimulation combined with the bladder functional training could improve the urination function in the patients with autonomic bladder after spinal cord injury.
