摘　　要：目的探讨超声及MRI联合应用在胎儿泌尿生殖系统异常诊断中的临床价值。方法对27例超声诊断为泌尿生殖系统异常的胎儿24h内行MRI检查并将超声、MRI图像、产后尸检或生后随访结果进行对比分析。结果超声、MRI、产后尸检或生后随访证实27例泌尿生殖系统异常胎儿中肾积水2例、肾缺如6例、肾脏囊性病变14例、融合肾3例、肾脏肿瘤1例、卵巢冠囊肿1例。超声能正确诊断多数胎儿泌尿生殖系统异常25例,MRI能正确诊断胎儿泌尿生殖系统异常26例。结论超声结合MRI可更精确诊断胎儿泌尿生殖系统异常,MRI在肾积水梗阻部位、泌尿系统畸形引起的肺发育不良及肾脏或肾包膜囊肿定位上能比超声提供更多诊断信息。Objective To compare the diagnostic value of prenatal ultrasound with magnetic resonance imaging（MRI）in the abnormalities of fetal urinary reproductive system,and explore the value of combining prenatal ultrasound and MRI in diagnosis of fetal urinary and reproductive system abnormalities. MethodsTwenty-seven fetal abnormalities in urinary reproductive system detected by prenatal ultrasound received MRI examination within 24 hours after ultrasound,confirmed by autopsy or clinical follow-up. The results of prenatal ultrasound and MRI were analyzed retrospectively. Results Ultrasound,MRI,autopsy or after birth,postpartum follow-up confirmed 27 cases of Genitourinary system anomalies,including 2 cases of hydronephrosis,renal agenesis in 6 cases,14 cases of renal cystic disease,renal fusion in 3 cases,1 case of renal tumors,ovarian cyst in one case of crown. Fetal ultrasound can diagnose the majority of the genitourinary system anomalies （25/27）,MRI can diagnose fetal anomalies of 26 cases of genitourinary system. Conclusion Ultrasound could diagnose the majority of fetal abnormalities in urology reproductive system accurately. However,combining ultrasound and MRI could establish more precise estimation in urology reproductive system,such as the level of obstruction of urinary system in hydronephrosis,the pulmonary hypoplasia secondary to urology system abnormalities,and location of cyst in the renal parenchyma or in the renal capsule.
