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。

OBJECTIVE: To assess the sensory integration function of children with primary nocturnal enuresis (PNE) and explore the role of sensory integration dysfunction in the pathogenesis of PNE. METHODS: Sensory integration function was assessed by the Childhood Sensory Integration Ability Development Checklist in 46 children with PNE and 46 normal children (control). RESULTS: The incidence of sensory integration dysfunction in the PNE group (82.6%) was significantly higher than that in the control group (43.5%)(P<0.01). Seventeen patients (36.9%) presented with severe sensory integration dysfunction in the PNE group but only 1 (2.1%) in the control group (P<0.01). The scores of all nine sensory integration indexes revealed by sensory integration function testing in the PNE group were significantly lower than those in the control group (P<0.01). CONCLUSIONS: Children with PNE have sensory integration dysfunction. Sensory integration dysfunction may be associated with the pathogenesis of PNE.
