Reconstruction of afferent and efferent nervous pathways to the urinary bladder in two paraplegic patients.

摘要: Based on animal experiments, spinal root anastomoses were performed in two paraplegic patients who had traumatic lesions of the conus medullaris. The aim was to reinnervate paralyzed urinary bladder. At operation, functioning T12 nerve roots above lesion transected and anastomosed bilaterally S2 S3 ventral dorsal emerging from injured cord area. About 1 year postoperatively, both demonstrated restoration micturition reflex as recorded cystometrogram. Both could feel urge void, initate voluntarily, empty their bladders satisfactorily. patients' relatively good bladder functions result either regeneration newly constructed nervous pathways or spontaneously developed partial upper neuron lesions.
