[Evaluation of neurogenic bladder in patients with spinal cord injury using a CMG.EMG study and CMG.UFM.EMG study].
Simultaneous recording of intravesical pressure, sphincter electromyography and uroflowmetry (CMG.UFM.EMG study) was performed following cystometry simultaneously with electromyography (CMG.EMG study) on 20 patients with spinal cord injuries. Differences in the influence to micturition between the CMG.EMG study and CMG.UFM.EMG study is thought to be due to whether the catheter is indwelling in the urethra or not. We examined those differences and patient's rehabilitation maneuver (Cred'e maneuver). Micturition pressure and opening pressure measured by the CMG.EMG study were larger than that measured by the CMG.UFM.EMG study (P less than 0.05, P less than 0.01 respectively). Incidence of detrusor-sphincter dyssynergia measured by the CMG.EMG study was greater than that measured by the CMG.UFM.EMG study in the detrusor hyperreflexic cases. The Cred'e maneuver caused increase in opening pressure, micturition pressure and peak flow rate, but the voiding volume and voiding time did not increase to any effective extent. The Cred'e maneuver exaggerated the detrusor sphincter dyssynergia.
