目的:分析产前超声在和泌尿系统畸形中的声像图像,同时对其临床诊断的价值进行分析。方法:选择我院在2013年9月-2014年9月间,到我院来进行超声诊断的患者,所有患者均检测出具有泌尿系统畸形,同时对这些图像资料进行分析,一共30例,同时将诊断结果和引产之后病理解剖或是分娩后体检随机访问的对结果进行对比、分析。结果:在30例畸形者中,肾积水、单侧肾、发育不良、马蹄肾、多囊肾、肾囊肿分别占36.7%、13.3%、10%、3.3%、6.7%、30%。其中20例引产,7例分娩,3例为死胎,产前超声检测与产后状况相一致的患者为29例,出现误诊状况的患者为1例,误诊类型是肾积水,经过随访后发现分娩后胎儿肾积水消失。结论:超声诊断对于胎儿的泌尿系统畸形诊断有着显著的临床意义及价值,在现实条件下,孕妇是需要进行定时进行超声诊断,同时对胎儿的发育情况进行观察、跟踪,以此来减少畸形的发生机率。 Objective: To analyze the image of prenatal ultrasound and urinary system deformity, and to analyze the value of its clinical diagnosis. Methods: All the patients in our hospital from September 2013 to September 2014 were enrolled in this study. All the patients were diagnosed as having urinary system malformation. At the same time, these images were analyzed in 30 cases. At the same time, The diagnostic results and post-abortion pathological anatomy or postpartum physical examination random access to the results were compared and analyzed. Results: Among the 30 cases of abnormalities, hydronephrosis, unilateral kidney, dysplasia, horseshoe kidney, polycystic kidney disease and renal cyst accounted for 36.7%, 13.3%, 10%, 3.3%, 6.7% and 30% respectively. Among them, 20 were induced labor, 7 were delivered and 3 were stillborn, and 29 were consistent with prenatal ultrasound examination and postpartum status. One patient with misdiagnosis status was hydronephrosis. After follow-up, delivery was found Hydronephrosis disappeared after the fetus. Conclusions: Ultrasound diagnosis has a significant clinical significance and value in the diagnosis of urinary malformations in fetus. Under the real conditions, pregnant women need to carry out ultrasonic diagnosis regularly, observe and track the development of the fetus in order to reduce the deformity Occurrence probability.
