| A epidemiology survey was sponsored to survey the situation of micturition function in 67 patients with spinal cord injuries. The results of self-made bladder controller to restore micturition function were evaluated in paraplegic dogs. An experimental study in canine models was performed to investigate the feasibility and theoretic base of the combination of bladder innervations and electric stimulation to restore the micturition function of atonic bladder which caused by sacral cord injury. The results showed the rehabilitation knowledge was insufficiency in paraplegias, so the doctors should enhance the rehabilitation guidance to the paraplegias to decrease the upper urinary tract damage. Self-made bladder controller together with a sacral deafferentation procedure can restore micturition function of paraplegic dogs. The micturition center in the sacral cord can be shifted and reconstructed by spinal nerve roots anastomosising, which can make up the limitation of bladder controller implantation, could not be apply to the patients with the cone injured. It is hopeful to provide a new reliable controllable micturition method for atonic bladder function reconstruction after the cone injury which caused thoracic-lumbar spine fracture. Sacral anterior roots electric stimulation hoped to be used for bladder function reconstruction of neurogenic bladder caused by spinal cord injuries.
