With rapid development of the scociety, spinal cord injury (SCI) caused by different accidents has been increased greatly. Neurogenic voiding dysfunction after SCI, which is a major medical and social problem to be resolved urgently, influences the life quality of the patient suffered from it heavily.  Today, there are many methods can be used to treat the neurogenic voiding dysfunction after SCI, including urethral catheterization such as suprapubic cystotomy, persistence catheterization and clean intermittent catheterization (CIC); compression voiding such as Crede maneuver and abdominal presser; pharmacological voiding to promotes voiding by drugs including cholinergic and anticholinergic agents acting on the detrusor,α-orβ-adrenal arousal (or block) agent targeting on the urethral sphincter; surgical voiding such as reinnervating of the bladder and rebuilding of bladder and urethra; voiding by sacral anterior root stimulation (SARS) to evok voiding by electric stimulation after sacral deafferentation (SDAF).  Research of restoring functional micturition has mainly focused on functional electrical stimulation for many decades. Since the failure of initial attempts to induce voiding via electrical stimulation of the spinal cord, or direct electrical stimulation on bladder muscle or pelvic nerve, a significant progress has been achieved through stimulation of sacral ventral roots with transection of the sacral dorsal roots. Despite being used in a few centers for nearly two decades, this procedure, however, has not been a choice of the treatment for the majority of SCI victims, because it involves in complicated surgery, and the clinical result is far from universal. Otherwise, there are some disadvantages such as failure of the electrodes may being difficult to re-implant, mechanical and electrical damage of the nerve may being permanent, and undesirable consequence that transection of the sacral dorsal roots may sacrifice residual sensory function of incomplete SCI patients.  Xiao CG, et al. proposed in 1989 to establish an artificial‘skin-CNS-bladder’reflex pathway below the site of spinal cord lesion (or just above the injured site for sacral spinal cord) as a means of restoring controllable micturition after SCI and successed both in
