Serial ultrasound scans were done in 300 fetuses between 16 to 24 weeks of gestation to establish the normogram of fetal kidney circumference (FKC) and fetal abdominal circumference (FAC) ratio (FKC/FAC). Of 300 fetuses, 150 fetuses were in the high risk group for fetal malformation and 150 patients were in the control group. The value of FKC/FAC varied from 0.27 to 0.30 from 16 to 24 weeks of gestation. No statistical difference was observed in the value of FKC/FAC in high risk and low risk (control) cases (p > 0.05). The value of FKC/FAC greater than or equal to 0.5 at 20 weeks or more was pathological for enlarged kidney. In 4 cases of multicystic kidney, the value of FKC/FAC ranged from 0.50 to 0.52 which was approximately 6SD above the normal mean ratio for that period of gestation.
对300例孕16至24周的胎儿进行了系列超声扫描,以建立胎儿肾周径(FKC)与胎儿腹围(FAC)比值(FKC/FAC)的正常图谱。在这300例胎儿中,150例为胎儿畸形高危组,150例为对照组。孕16至24周时,FKC/FAC值在0.27至0.30之间。高危组和低危(对照)组的FKC/FAC值无统计学差异(p>0.05)。孕20周及以上时,FKC/FAC值大于或等于0.5提示肾脏增大为病理性。在4例多囊肾病例中,FKC/FAC值在0.50至0.52之间,比该孕周正常平均比值高出约6个标准差。
