This study has been undertaken to determine the frequency and pattern of urinary tract anomalies diagnosed by ultrasound, to correlate the prenatal with postnatal diagnoses and to identify prognostic factors.
The Ultrasound Unit's database was reviewed for fetal urinary tract anomalies detected between January 2002 and June 2012. Prenatal diagnoses made by ultrasound were confirmed by postnatal ultrasound, as well as with surgical reports. Statistical analysis was performed using the Mann-Whitney U-test, Chi-square and Fisher's exact tests. p values <0.05 were considered significant.
A total of 838 fetal malformations were prenatally diagnosed by ultrasound with a frequency of 21% of urinary tract anomalies (177/838). Renal pelvis dilatation and hydronephrosis accounted for more than half of the cases (52%). The most frequent postnatal diagnoses were also urinary tract dilatations. The prenatal diagnoses corresponded to the postnatal ones in 88.8% of cases. There was a highly significant association between anterior-posterior renal pelvis diameter above 10 mm in the last ultrasound performed before the birth and the need for surgery (p < 0.01).
We emphasize the high degree of reliability of prenatal ultrasound in the establishment of diagnosis of urinary tract malformations and the prediction of postnatal outcomes.
本研究旨在确定超声诊断的泌尿系统异常的频率和模式，将产前诊断与产后诊断进行关联，并确定预后因素。
回顾超声科2002年1月至2012年6月间检测到的胎儿泌尿系统异常的数据库。超声的产前诊断通过产后超声以及手术报告得以证实。使用曼-惠特尼U检验、卡方检验和费舍尔精确检验进行统计分析。p值<0.05被认为具有显著性。
超声产前共诊断出838例胎儿畸形，泌尿系统异常的频率为21%（177/838）。肾盂扩张和肾积水占病例的一半以上（52%）。最常见的产后诊断也是泌尿系统扩张。产前诊断与产后诊断在88.8%的病例中相符。出生前最后一次超声检查时肾盂前后径大于10毫米与手术需求之间存在高度显著的关联（p<0.01）。
我们强调产前超声在泌尿系统畸形诊断的确立及产后结局预测方面具有高度可靠性。
