目的:探讨泌尿系统畸形的产前超声诊断思维方法和临床实用价值。方法:应用常规超声或系统超声检查发现肾脏异常者,仔细观察肾脏大小、形态、内部回声特点、肾盏情况、有无正常肾脏组织,病变的部位、大小、形态特征、彩色血流分布情况等,同时仔细观察是否合并胎儿输尿管、膀胱异常、羊水异常以及其他胎儿及附属物异常,必要时检查孕妇肾脏。结果:37 332例胎儿中,发生泌尿系统畸形82例,发生率0.22%(82/37 332)。产前超声检出65例,检出率79.27%(65/82),漏诊7例,误诊10例,漏误诊率20.73%(17/82)。结论:胎儿泌尿系统畸形的产前超声诊断及鉴别诊断对临床处理非常关键,无羊水或羊水过少是诊断泌尿系统畸形最初和最重要的线索。
Objective: To investigate the prenatal ultrasound diagnostic thinking and clinical value of urinary system deformity. Methods: The abnormalities of the kidneys were observed by conventional ultrasound or ultrasonography. The kidneys’ size, morphology, internal echo characteristics, renal calyx, normal kidney tissue, the location of the lesion, size, morphological features and color flow distribution were observed carefully At the same time carefully observe whether the merger of fetal ureter, bladder abnormalities, amniotic fluid abnormalities and other fetuses and ancillary anomalies, if necessary, check the pregnant women kidney. Results: In 37 332 fetuses, 82 cases of urinary system malformations occurred, the incidence rate was 0.22% (82/37 332). Prenatal ultrasound detected 65 cases, the detection rate was 79.27% (65/82), missed diagnosis in 7 cases, misdiagnosis in 10 cases, missed misdiagnosis rate of 20.73% (17/82). Conclusion: Prenatal ultrasound diagnosis and differential diagnosis of fetal urinary system malformations are very important for clinical treatment. No amniotic fluid or oligohydramnios is the first and most important clues to diagnose urinary malformations.
