在过去的十年里,发育不全或发育不良的先天性肾脏异常发生率逐渐增加。其原因是由于高分辨率的阴道超声探头,以致能够早在妊娠中三月(孕中季)开始即可准确检出泌尿系统的异常。为评价妊娠中三月早期使用阴道超声检查(TVS)轻度肾脏畸形的可能性,以及探讨对查出这类畸形后可能发生远期并发症的临床意义,研究自1988年11月～1992年8月所进行的6350例连续TVS。由同一超声专家对妊娠中三月早期(14～18周)胎儿进行检查,选用 In the past decade, the incidence of congenital anomalous renal dysplasia or dysplasia gradually increased. The reason is due to the high resolution of the vaginal ultrasound probe, so that as early as the third trimester (third trimester) pregnancy can accurately detect abnormal urinary system. To assess the possibility of using mild vaginal ultrasound (TVS) for mild kidney malformations in early March of pregnancy and to explore the clinical implications for the detection of long-term complications that may occur after such deformities, studies were performed from November 1988 to 1992 6350 consecutive TVS conducted in August. By the same ultrasound experts in early March of pregnancy (14 to 18 weeks) to check the fetus, selection
