肾母细胞瘤是小儿常见恶性实体肿瘤,在综合治疗措施中化疗起了重要作用。超声对瘤体的大小、内部结构及邻近器官进行观察,可提供肾母细胞瘤分期特征及观察化疗的效果。我院1985年1月～1999年12月对64例肾母经胞瘤术前化疗期间行超声随访观察,并与手术和病理检查进行对照,现予以分析报告。 资料和方法 近14年来超声检查术前化疗期间肾母细胞瘤64例,男性37例,女性27例,年龄范围1月～8岁,平均2.6岁,3岁以下52例(占61％)。临床因腹部扪及肿块、血尿及贫血而行超声检查。采用Hitachi EUB—40,Aloka SSD—1200及Acuson 128 XP超声诊断仪,探头频率5MHz或3MHz。经前腹壁、两腰部及背部多切面检查。观察肿瘤与残存肾脏之间的位置关系,测量肿瘤上下径、左右径及前后径。注意肿瘤包膜、内部结构及血管走向,肿瘤与邻近器官的关系,下腔静脉、心脏及肝脏有无转移病灶。
Nephroblastoma is a common malignant tumor in children. Chemotherapy plays an important role in the comprehensive treatment. Ultrasound on the size of the tumor, the internal structure and the adjacent organs were observed to provide staging features of nephroblastoma and observe the effect of chemotherapy. In our hospital from January 1985 to December 1999 64 cases of renal cell tumor during preoperative chemotherapy were followed up by ultrasound and surgery and pathological examination were compared to the analysis report. Materials and Methods 64 cases of Wilms’ tumor during preoperative chemotherapy during the past 14 years, including 37 males and 27 females, ranging in age from 1 month to 8 years (average 2.6 years) and 52 years (61%) under 3 years old. Clinical abdominal palpable mass, hematuria and anemia line ultrasound. Using Hitachi EUB-40, Aloka SSD-1200 and Acuson 128 XP ultrasonic diagnostic apparatus, the probe frequency of 5MHz or 3MHz. The anterior abdominal wall, two waist and back multi-faceted examination. Observe the tumor and the relationship between the residual kidney, the tumor diameter, diameter and anteroposterior diameter. Note that the tumor capsule, the internal structure and vascular trends, the relationship between the tumor and the adjacent organs, the inferior vena cava, heart and liver with or without metastatic lesions.
