目的 :了解我国肾发育不良的流行病学特点及基本状况。方法 :1987～ 1992年中国出生缺陷监测网以医院为基础在全国对孕 2 8周至产后 7天的围产儿进行监测 ,对 131例肾发育不良患儿进行流行病学分析。结果 :我国肾发育不良的发生率为 0 .2 9/万 ,发生率近 6年下降 78%。城乡发生率、男女发生率差异均无显著性。 6 0 .31%的肾发育不良患儿为低体重儿。肾发育不良常伴发一至三种其他畸形 ,与直肠肛门畸形、神经管畸形和外阴性别不明伴发频率较高。结论 :肾发育不良常伴发多种畸形 ,其围产儿的素质较差 ;我国肾发育不良发生率呈下降趋势。
Objective: To understand the epidemiological characteristics and basic status of renal dysplasia in our country. Methods: From 1987 to 1992, China Birth Defective Monitoring Network monitored the perinatal children in China from 28 weeks pregnant to 7 days postpartum on the basis of hospital, and conducted epidemiological analysis on 131 cases of kidney dysplasia. Results: The incidence of renal dysplasia in China was 0.29 million, the incidence of which dropped by 78% in the past 6 years. The incidence of urban and rural areas, the incidence of men and women were no significant differences. Sixty-three percent of children with dysplasia were of low birth weight. Often accompanied by renal dysplasia one to three other deformities, and anal anorectal malformation, neural tube defects and vulvar gender unknown associated with a higher frequency. Conclusion: Kidney dysplasia often accompanied by a variety of deformities, the quality of their perinatal poor; the incidence of renal dysplasia in China showed a downward trend.
