Bladder electromyography: response to electric stimulation and to terbutaline.
Four patients with traumatic spinal cord injuries and paraplegia received electric stimulation of the conus medullaris. An additional 5 patients with traumatic spinal cord injuries and paraplegia received terbutaline for asthma. All 9 patients were studied with bladder and external urethral sphincter electromyography (EMG). Bladder pressures were recorded in the electric stimulation group and cystometry in the terbutaline group. The electric impulses were recorded without attenuation, and bladder and external urethral sphincter contractility increased. Terbutaline reduced the bladder's electric activity and pressure at capacity without affecting external urethral sphincter function. More evaluations of terbutaline's effect on the bladder are necessary to determine its applicability to incontinence problems.
