目的 探讨儿童精神性尿频的病因、病理生理变化及其治疗。方法 本组 38例 ,应用尿流动力仪分别记录排尿量、尿流曲线、膀胱压力容积及压力 流率 肌电图。结果 38例中 ,4例尿动力学完全正常 ;34例出现膀胱功能异常 ,占 89.5 % (34/ 38) ,其中逼尿肌不稳定性收缩者 12例 ,低顺应性膀胱者 6例 ,低顺应性膀胱合并逼尿肌不稳定性收缩者 16例 ;最大膀胱测量容量百分数下降14例。排尿期异常仅 5 .3% (2 / 38) ,为尿道括约肌过度活跃。尿动力学检测后 ,84 .2 %的患儿症状完全消失或好转。结论 逼尿肌不稳定性收缩是最主要的病理生理学改变 ;排尿训练是主要治疗措施。
Objective To investigate the etiology, pathophysiological changes and treatment of psychiatric urinary frequency in children. Methods 38 cases in this group, the use of urodynamic apparatus were recorded urine output, urinary flow curve, bladder pressure volume and pressure flow rate EMG. Results Among 38 cases, 4 cases were completely normal urodynamics, 34 cases had abnormal bladder function, accounting for 89.5% (34/38), including 12 cases of detrusor instability and 6 cases of low compliance bladder Complicated bladder detrusor instability with contraction of 16 cases; the largest percentage of bladder capacity decreased in 14 cases. Urination abnormalities only 5.3% (2/38), urethral sphincter over-active. After urodynamic testing, 84.2% of children with symptoms completely disappeared or improved. Conclusion Detrusor instability is the most important pathophysiological changes; micturition training is the main treatment.
