Gas cystometry combined with electronically integrated sphincter electromyography provides a rapid and effective screening technique for evaluation of patients with disorders of micturition secondary to neurologic dysfunction. The most frequent cystometric patterns are (1) detrusor hyperreflexia secondary to interruption of the cortico-regulatory tracts and (2) detrusor areflexia secondary to impairment of the segmental innervation of the detrusor muscle. To observe these patterns it is necessary to perform detrusor reflex activation procedures, including change in posture, administration of bethanechol, and urethral and rectal distention. The two prinicpal sphincter disturbances observed with electronically integrated electromyography are detrusor sphincter dyssnergia and uninhibited sphincter relaxation. The delineation of combination of abnormal cystometric and sphincter responses provides for rational selection of pharmacologic and surgical therapy.
膀胱测压法结合电子集成括约肌肌电图为评估继发于神经功能障碍的排尿障碍患者提供了一种快速有效的筛查技术。最常见的膀胱测压模式为：（1）继发于皮质调节束中断的逼尿肌反射亢进；（2）继发于逼尿肌节段性神经支配受损的逼尿肌无反射。为观察这些模式，有必要进行逼尿肌反射激活程序，包括改变体位、给予氨甲酰甲胆碱以及尿道和直肠扩张。通过电子集成肌电图观察到的两种主要括约肌功能障碍为逼尿肌括约肌协同失调和括约肌无抑制性松弛。对异常膀胱测压和括约肌反应组合的描述有助于合理选择药物和手术治疗方法。
