To establish a nomogram of fetal kidney length for a normal pregnancy from 20 to 41 weeks of gestational age.
A prospective cross-sectional study was carried out in the Department of radio-diagnosis and imaging BPKIHS, Dharan. 400 kidneys of 200 fetuses between the gestational age 20 to 41 weeks were scanned. Renal measurement was performed by ultrasonography.
Analysis was performed on data obtained from 200 normal fetuses. Size charts for right, left and mean fetal kidney length with standard deviation were presented for each weeks of gestation from 20 weeks to 41 weeks. The difference in renal length between right and left side was statistically not significant.There was significant correlation between gestational age and fetal kidney length (r=0.947, p=0.001).
Fetal kidney length can be used as an adjunct parameter for estimation of gestation age.
建立孕20至41周正常妊娠胎儿肾长的列线图。
在达兰BPKIHS放射诊断与影像科进行了一项前瞻性横断面研究。对200例孕20至41周胎儿的400个肾脏进行了扫描。通过超声检查进行肾脏测量。
对从200例正常胎儿获得的数据进行了分析。给出了孕20周-41周各孕周右侧、左侧及平均胎儿肾长的尺寸图表及标准差。左右侧肾长差异无统计学意义。孕周与胎儿肾长之间存在显著相关性（r=0.947，p=0.001）。
胎儿肾长可作为估计孕周的辅助参数。
