肾脏恶性肿瘤的超声诊断(附28例分析)

The ultrasonographic diagnosis of renal malignant tumor (with 28 cases)

目的探讨肾脏恶性肿瘤的超声及其他影像学诊断。方法对28例经B超及其他影像学检查,并经手术、病理证实的病例进行回顾性分析。结果B超定性诊断肾癌20例(20/28);螺旋CT定性诊断10例(10/17);MRI定性诊断7例(7/10)。结论对于大于1cm的肾癌,B超及其他影像学检查定性诊断率相差不大;熟悉肾脏恶性肿瘤的二维及多普勒超声表现,结合临床病史及其他影像学检查,是减少漏、误诊,提高超声诊断水平的关键。

Objective To study the ultrasonographic and other imaging methods for diagnosing renal malignant tumor. Methods ultrasonographic and other imaging findings from 28 patients with renal malignant tumor confirmed by operation and pathology were retrospectively analyzed. Results 20 cases (20/28) were qualitatively diagnosed by ultrasonography, 10 cases (10/17 ) were qualitatively diagnosed by spiral CT, and 7 cases(7/10) by MRI. Conclusion The rate of qualitative diagnosis using the ultrasonography is similar to that by the other imaging examination in finding the renal malignant tumor which is less than 1 cm in diameter; being familiar with 2D ultrasonographic and Doppler findinfs of the renal malignant tumor, and combining with clinical history and other imaging findings are the key to reduce misdiagnosis and omissive diagnosis and to improve the diagnostic level of ultrasonography .
