To evaluate the features of the clinical findings in three types (types I, IIa, IIb) of enuresis, classified by overnight simultaneous monitoring by electroencephalography (EEG) and cystometry (CM).
We performed a test to evaluate bladder capacity, arousal response and the pattern of nighttime urination in sucklings and infants.
As for the values of enuretic bladder capacity (EBC), the smallest were found in enuresis type IIb. As for arousal response, enuresis type I showed the best, while enuresis type IIa showed the worst response. With regard to the pattern of nighttime urination in sucklings and infants, all sucklings had a stable bladder in the sleep state and urinated in the pattern of type IIa. The arousal response to bladder distention indicating type I appeared at the age of about 2 or 3.
The smallest EBC in patients with enuresis type IIb represented a bladder dysfunction in the sleep period. It was observed that patients with enuresis type I had the best arousal function while those with enuresis type IIa had the worst arousal function. All sucklings urinated unconsciously during sleep in the pattern of type IIa. The arousal response to bladder distention indicating type I, which was not observed below the age of 1 year, was thought to appear at the age of about 2 or 3 years. If this change has not appeared by the age of 3, bed-wetting might persist after the age of 5.
通过脑电图（EEG）和膀胱测压法（CM）夜间同步监测，评估三种类型（I型、IIa型、IIb型）遗尿症的临床特征。
我们进行了一项测试，以评估婴儿和幼儿的膀胱容量、觉醒反应及夜间排尿模式。
就遗尿膀胱容量（EBC）值而言，IIb型遗尿症患者的值最小。就觉醒反应而言，I型遗尿症表现最佳，而IIa型遗尿症表现最差。关于婴儿和幼儿的夜间排尿模式，所有婴儿在睡眠状态下膀胱都很稳定，且排尿模式为IIa型。提示I型的对膀胱扩张的觉醒反应大约在2岁或3岁时出现。
IIb型遗尿症患者最小的EBC代表睡眠期膀胱功能障碍。观察到I型遗尿症患者的觉醒功能最佳，而IIa型遗尿症患者的觉醒功能最差。所有婴儿在睡眠期间均以IIa型模式无意识排尿。提示I型的对膀胱扩张的觉醒反应在1岁以下未观察到，被认为大约在2岁或3岁时出现。如果这种变化在3岁时仍未出现，5岁后可能会持续尿床。
