尿动力学检测在儿童尿频症中的应用

目的 探讨儿童白天尿频症的尿流动力学病理改变和治疗方法.方法 随机选择40例白天尿频症患儿,进行尿动力学检测,观察尿流曲线、功能性膀胱容量(FBC)、逼尿肌稳定性及不稳定性指数、膀胱顺应性(BC)、最大膀胱测量容量(CBCmax)及CBCmax百分数、逼尿肌与尿道外括约肌协同性.在充盈性膀胱内压测定过程中当膀胱容量达正常CBCmax之前出现逼尿肌不稳定性收缩(DI)时嘱患儿收紧盆底肌、延长储尿时间,进行膀胱储尿功能训练,其中20例合并有DI的患儿在相同条件下间隔30 min再行充盈性膀胱内压测定,比较两次测定的CBCmax百分数和不稳定指数.同期选15名排尿正常儿童做对照研究.结果 膀胱充盈期出现DI 17例,DI合并低顺应性膀胱15例,单纯低顺应性膀胱4例,充盈性膀胱内压测定正常4例.3例排尿期盆底肌电活动间断增强.CBCmax下降28例.第1次CBCmax与FBC比较有明显增加(P＜0.05).20例进行2次充盈性膀胱内压测定,第2次逼尿肌不稳定指数明显下降(P＜0.05)、CBCmax百分数明显增加(P＜0.05).而正常对照组2次CBCmax无明显差异.结论 儿童白天尿频症的主要尿动力学病理变化是DI,低顺应性膀胱和CBCmax降低是DI引起逼尿肌收缩的继发改变,均为功能性紊乱,而非膀胱壁组织结构器质性病变.行为疗法是治疗儿童尿频症的有效方法,其中以排尿训练为主,抗胆碱能药可辅助治疗儿童尿频症.

Abnormal urodynamic findings in children with nocturnal enuresis

Reduced nocturnal bladder capacity has been suggested in the pathogenesis of nocturnal enuresis. This study was conducted to define frequency of bladder dysfunction in enuretic children and determine parameters which might predict bladder dysfunction. 60 children were enrolled. Full urodynamic study (UDS) was done in case of abnormal uroflowmetry, abnormal bladder ultrasound, daytime incontinence and age 10 years. Of 60 patients ultrasound 48 underwent complete UDS. In 11, results of UDS were unreliable. The results were normal in 10 (20.8%) and 27 (56.2%) had abnormal UDS.The study revealed that abnormal UDS is common in enuretic children and overactive bladder is the most common findings. No clinical feature were found, which could identify children requiring UDS.     

遗尿症儿童感觉统合能力的研究

目的：分析原发性夜间遗尿症(PNE)儿童的感觉统合能力,探讨感觉统合失调在原发性遗尿症发生中的作用。方法：采用感觉统合能力发展量表对46例PNE组儿童及46例正常对照组儿童进行感觉统合功能测试,对两组结果采用t检验和χ2检验进行统计分析。结果：PNE组与对照组儿童感觉统合失调的发生率分别为82.6%和43.5%,其中重度失调的发生率分别为36.9%和2.1%,两组间差异有显著性（P﹤0.01）;PNE组所有感觉统合功能因子得分均明显低于对照组,差异有显著性(P﹤0.01)。结论：PNE组儿童存在感觉统合失调现象,感觉统合功能失调在PNE发生中可能有一定作用。     

小儿原发性夜间遗尿症尿动力学评价的初步探讨

目的 探讨小儿原发性夜间遗尿症的病因和膀胱功能改变。方法 本组63例，男39例，女24例。在清醒和自然睡眠相进行充盈期膀胱压力容积测定，记录睡眠相盆底肌电活动变化。结果 58例存在膀胱功能紊乱，多种异常合并为五种模式。其中，睡眠相逼尿肌不稳定收缩占71.4%(45/63)，睡眠相膀胱最大测量容量下降占36.5%(23/63)。睡眠相逼尿肌不稳定收缩出现时，逼尿肌与盆底肌肉协同失调者11例。结论 逼尿肌不稳定收缩是遗尿发生的主要原因，盆底肌肉与逼尿肌的协同失调可能是原因之一，膀胱容量下降是逼尿肌不稳定收缩所致的遗尿结果而不是原因。     

Enuresis in children. Diagnostic assessment and treatment

Many theories on the etiology of enuresis have been suggested, including psychogenic, structural abnormalities, dysfunctional aspects. The study consisted of 95 children with primary enuresis (35 girls, 60 boys). 58% of patients presented with enuresis plus evidence of voiding dysfunction. Patients with pure nocturnal enuresis were 17%. 42% of children have normal bladder on urodynamic testing. Anticholinergic medication was effective in children with voiding dysfunction. The base line treatment program, in children with normal urodynamic studies, included psychotherapy, medications, bladder training. Authors present their experience and results of treatment. The usefulness of urodynamic assessment in children with only nocturnal enuresis is discussed.     

原发性遗尿症儿童感觉统合能力的对照研究

目的：探索儿童原发性夜间遗尿症（PNE）与感觉统合能力的关系。方法：采用儿童感觉统合能力发展量表,对70例PNE患儿进行感觉统合功能测试,并与74例正常儿童进行对照研究。结果：PNE组感觉统合失调发生率 (76% vs 35%)、重度感觉统合失调发生率(39% vs 18%) 明显高于对照组,差异有统计学意义（P<0.01）。PNE组儿童所有感觉统合功能因子得分均明显低于对照组,差异有统计学意义（P<0.01）。结论：PNE患儿普遍存在感觉统合失调,并且是多方面的,故对PNE患儿进行感觉统合功能测试,并针对性地对伴发的感觉统合失调问题进行训练很有必要。［中国当代儿科杂志,2010,12（5）：341-343］     

Family and segregation studies: 411 Chinese children with primary nocturnal enuresis

BACKGROUND: The aim of the present paper was to determine the incidence of primary nocturnal enuresis (PNE) among relatives of Chinese children with PNE, the inheritance pattern, and to identify the characteristics of PNE with positive family history. METHODS: From July 2003 to June 2004, an epidemiological survey on PNE children was carried out by self-administered questionnaires to parents of 5-18-year-old Chinese students in Henan Province, central China. A detailed family history was recorded in order to determine the presence of familial PNE as defined as any close relative with PNE beyond the age of 5 years. RESULTS: The response rate was 88% (10 383/11 799), and 411 children (235 boys and 176 girls) with PNE were identified. A positive family history was found in 94 families (22.87%) of 411 probands with PNE, including 48.94% of fathers, 8.51% of mothers, 6.38% of both parents, 6.38% of the siblings and 29.79% of grandfathers or (and) mothers. Among the probands the ratio of male to female was 1.3:1 excluding sex-linked inheritance. Autosomal dominant inheritance was in 14.60%, and autosomal recessive inheritance was consistent in 1.46% of families. In PNE children with positive family history, the proportion of adolescents, with associated daytime symptoms, marked PNE and seeking professional help were significantly higher than those in PNE children without positive family history. CONCLUSIONS: PNE has a significant family clustering, and all modes of inheritance can occur in different families on the basis of a formal genetic analysis. Those with positive family history often manifest marked PNE, and have daytime symptoms.     

Bladder wall thickness and urodynamic correlation in children with primary nocturnal enuresis

ObjectiveTo investigate the correlations between ultrasonographic bladder wall thickness (BWTh) and urodynamic study (UDS) findings and estimate the diagnostic value of BWTh for prediction of DO in children with monosymptomatic and non-monosymptomatic primary nocturnal enuresis (PNE).Patients and methodsUltrasound measurements (US) and UDS were performed on a total of 100 children, 50 consecutive boys and 50 consecutive girls, 6–14 years old, with monosymptomatic PNE (group 1, n = 75), and non-monosymptomatic PNE (group 2, n = 25). The US Protocol was specially designed for the evaluation of BWTh. All children underwent urodynamic studies for detailed assessment of any underlying bladder overactivity. Findings were compared between the two groups of patients.ResultsThe mean BWTh was increased in the group 2 compared to the group 1 (mean ± SD = 2.4 ± 0.41 mm, mean ± SD = 1.52 ± 0.18 mm respectively, p < 0.05). Detrusor overactivity (DO) occurred in 23/75 (30.5%) children of the group 1 and in 17/25 (68%) children of the group 2 (p < 0.05). Comparing the BWTh between the two groups of patients and the UDS findings, it was found that BWTh was significantly correlated with DO(r = 0.92 and p < 0.001), children with DO presented significantly increased BWTh compared to those without (mean ± SD = 2.1 ± 0.4 mm, mean ± SD = 1.5 ± 0.4 mm respectively, p < 0.05) and the maximum amplitude of DO occurred in 20 children who had non-monosymptomatic PNE.ConclusionsWe suggest that BWTh could be applied as a screening tool to identify the cases of DO between the children with PNE. Children with non-monosymptomatic PNE presented increased BWTh and higher percentages of DO.
