【摘要】 目的探讨腹膜后纤维化(RPF)的超声影像学特征。方法回顾分析10例经手术病理证实的RPF患者的超声征象,观察腹膜后有无异常团状回声,记录病灶位置、大小、形态、回声、毗邻及血供情况。结果 10例RPF患者腹主动脉周围均可见团状低回声包绕,4例下腔静脉亦受累;8例伴泌尿系阳性征象,其中3例双侧肾积水,输尿管扩张,低回声病灶包绕输尿管;3例左侧肾积水、输尿管扩张;2例右侧肾积水,梗阻水平以上输尿管明显扩张。超声明确诊断5例,2例仅提示肾积水或输尿管扩张,3例诊断为腹部包块。结论 RPF主要以腹膜后大血管周围的软组织团状回声为特异性征象,特别是超声首诊发现不明原因的肾积水、输尿管扩张时,应考虑该病的可能。更多还原

【Abstract】 Objective To explore the ultrasonographic features of retroperitoneal fibrosis(RPF). Methods The ultrasonographic findings of 10 cases with RPF were summarized,the retroperitoneal abnormal mass echo was observed,and the location,size,shape,echo,adjacent and blood supply of the mass were record.Results The abdominal aorta of 10 patients were found to be surrounded by hypoechoic mass,and inferior vena cava of 4 cases were also affected.8 cases were associated with urinary positive signs,dilatation of bilateral hydronephrosis and ureter,and hypoechoic lesions around the ureter in 3 cases,left hydronephrosis and ureter dilatation in 3 cases,right hydronephrosis,obstruction level above the ureter significantly dilated in2 cases.Ultrasonic diagnosis was confirmed in 5 cases,2 cases were only prompted uronephrosis or ureterectasia,and 3 cases were diagnosed as abdominal mass.Conclusion The ultrasonic specific sign of RPF is mainly the soft tissue hypoechoic mass around the retroperitoneal artery,especially there are unexplained uronephrosis and ureterectasia in the initial diagnosis,the possibility of the disease should be considered.更多还原
