We reviewed 54 cases of detrusor-external sphincter dyssynergia following complete urodynamic evaluations. All patients had well defined neurologic lesions of the suprasacral spinal cord. On the basis of urodynamic findings 3 types of dyssynergia were encountered: type 1 (30 per cent) was characterized by a crescendo increase in electromyographic activity that reached a maximum at the peak of the detrusor contraction, type 2 (15 per cent) consisted of clonic sphincter contractions interspersed throughout the detrusor contraction and type 3 (55 per cent) was characterized by a sustained sphincter contraction that coincided with the detrusor contraction. There was no correlation between the clinical neurologic level and the type of dyssynergia.
我们回顾了54例经过完整尿动力学评估的逼尿肌-外括约肌协同失调病例。所有患者均有明确的骶上脊髓神经损伤。根据尿动力学检查结果，发现了3种类型的协同失调：1型（30%）的特征是肌电图活动呈渐进性增加，在逼尿肌收缩峰值时达到最大值；2型（15%）表现为阵挛性括约肌收缩穿插于整个逼尿肌收缩过程中；3型（55%）的特征是括约肌持续收缩并与逼尿肌收缩同时出现。临床神经损伤平面与协同失调类型之间无相关性。
