【摘要】：目的探讨超声检查诊断单纯性单侧多囊性发育不良肾(MCDK)的价值。方法回顾性分析于我院产前诊断中心进行产前系统超声筛查检出的29胎单纯性单侧MCDK胎儿。在排除孕妇妊娠合并征、胎儿合并有其他结构异常及胎儿染色体核型异常后,对其中15胎继续妊娠并进行随访的胎儿跟踪观察至产后,观察胎儿患侧肾脏的声像图变化特征、健侧肾脏形态及大小、患儿生长发育及肾功能有无受损。结果 15胎单侧MCDK胎儿,最短随访时间为孕期至出生后7个月,最长随访时间为孕期至患儿5周岁。超声显示胎儿时期患侧肾脏体积常先变大,至妊娠晚期近足月时肾脏体积多逐渐缩小,至出生后5~6个月时患侧肾脏常已萎缩,甚至超声无法探及。而健侧肾脏的形态、大小、声像图特征与正常同孕龄胎儿相似。产前胎儿生长发育指标及羊水量均在正常。出生后,除1例患儿体质量过重外,其余患儿的生长发育指标均在正常范围。结论胎儿单纯性单侧MCDK多预后良好,超声在检查及随访中有重要价值,可为产前诊断咨询提供可靠依据。
[Abstract]:Objective to evaluate the value of ultrasonography in the diagnosis of simple unilateral multiple cystic dysplasia (MCDK). Methods 29 single unilateral MCDK fetuses were screened by prenatal system in our prenatal diagnosis center. Except for pregnant women with pregnancy syndromes, After the fetus had other structural abnormalities and fetal chromosomal karyotype abnormalities, 15 of them continued to be pregnant and followed up to the postpartum to observe the sonographic changes of the affected kidney, the shape and size of the healthy kidney. Results Fifteen one-sided MCDK fetuses were followed up from pregnancy to 7 months after birth. The longest follow-up period was from pregnancy to 5 years of age. Ultrasound showed that the size of the affected kidney usually increased first in the fetal period, decreased gradually in the late term of pregnancy, and was often atrophied at 5 ~ 6 months after birth. The shape, size and sonographic characteristics of the normal kidney were similar to those of the normal fetuses of the same gestational age. The prenatal fetal growth and development indexes and amniotic fluid volume were all normal. Conclusion simple unilateral fetal MCDK has a good prognosis, and ultrasound has important value in examination and follow-up, which can provide reliable basis for prenatal diagnosis consultation.
