A study of 6350 consecutive transvaginal ultrasound examinations was performed as part of a routine fetal evaluation. Twenty-one cases (0.33 per cent) of early second-trimester sonographic detection of minor renal abnormalities (unilateral renal agenesis, pelvic kidney, and double collecting system) are presented. The sonographic diagnosis was made at 14-18 weeks of pregnancy and confirmed, in all of the 21 fetuses, postnatally or by post-mortem. A high incidence of associated fetal anomalies (24 per cent) and parental renal abnormalities (14 per cent) was demonstrated. Transvaginal sonography was found to be a useful tool for diagnosing these renal anomalies as early as 14 weeks of pregnancy. The likelihood of various associated anomalies and long-term implications on renal function raise questions concerning the prenatal management of such patients.
作为常规胎儿评估的一部分，对连续6350例经阴道超声检查进行了研究。本文报告了21例孕中期早期超声检测到的轻度肾脏异常（单侧肾缺如、盆腔肾和双集合系统）病例（占0.33%）。超声诊断在妊娠14 - 18周做出，并且在所有21例胎儿中，产后或尸检后得到证实。研究显示相关胎儿异常（24%）和父母肾脏异常（14%）的发生率较高。经阴道超声检查被发现是早在妊娠14周时诊断这些肾脏异常的有用工具。各种相关异常的可能性以及对肾功能的长期影响引发了对此类患者产前管理的疑问。
