Simultaneous recordings of electromyography of the external urethral sphincter and bladder pressure during voiding were done for 71 male patients with spinal cord injury. Discordant activities between the anal and the external urethral sphincters were noted in 39 per cent of the patients. The degree of bladder dysfunction was related more to the degree of dyssynergia of the urethral than the anal sphincter. This detrusor-sphincter dyssynergia was found in 67 per cent of our patients regardless of the differences in cystometric patterns and the level of spinal injury. The importance of electromyography of the external urethral sphincter in the diagnosis of neurogenic bladder dysfunction was stressed. The management of detrusor-sphincter dyssynergia is discussed briefly.
对71例脊髓损伤男性患者在排尿期间同时进行尿道外括约肌肌电图和膀胱压力记录。在39%的患者中观察到肛门和尿道外括约肌之间的不协调活动。膀胱功能障碍的程度与尿道括约肌而非肛门括约肌的协同失调程度关系更大。无论膀胱测压模式和脊髓损伤水平存在差异，在我们67%的患者中都发现了这种逼尿肌-括约肌协同失调。强调了尿道外括约肌肌电图在神经源性膀胱功能障碍诊断中的重要性。简要讨论了逼尿肌-括约肌协同失调的处理方法。
