胎儿泌尿系统畸形的产前超声诊断与产后随访及引产后尸体解剖的对比分析

目的 提高泌尿系统畸形产前超声检查的准确率. 方法 将产前超声检查发现单纯泌尿系统畸形或合并其他系统畸形的14例胎儿进行产后超声随访及引产后进行尸体解剖,将随访结果及尸体解剖结果与产前超声检查结果进行对比分析. 结果 产前超声诊断14例泌尿系统畸形.共有泌尿系统畸形24处,产前超声诊断19处,灵敏度98％,特异度85.4％；准确率79.2％,漏诊率20.8％. 结论 产前超声检查发现胎儿泌尿系统畸形的准确率较高,对该疾病的早期发现有重要意义.

The comparative analysis of the prenatal ultrasound,postpartum follow-up and autopsy in the diagnosis of renal tract anomalies

Objective To improve the accuracy of prenatal ultrasound diagnosis of congenital renal tract anomalies.Methods A total of 14 cases with congenital renal tract anomalies or multi-malformations were retrospectively studied.The results of prenatal ultrasound,postpartum follow-up and autopsy were compared.Results In 14 cases,totally 24 anomalies or malformations were found by postpartum follow-up or autopsy.Among them,19 malformations were correctly detected by prenatal ultrasound,with the accuracy of 79.2%,the sensitivity of 98%,and the specificity of 85.4%;There were 5 missed diagnosis cases.Conclusion Prenatal ultrasound scanning is sensitive and precision in detecting renal tract anomalies,with great significance for the eugenic and superior nurture.
