超声造影在膀胱占位性病变诊断中的应用

Application of contrast-enhanced ultrasound in diagnosis of bladder occuPied lesions

目的:探讨超声造影在膀胱占位性病变诊断中的临床应用价值。方法:对25例膀胱占位性病变行实时超声造影,观察并分析病灶的超声造影表现,总结超声造影灌注时相的动态变化规律,并与病理结果相对照。结果:超声造影提示膀胱恶性肿瘤17例(26个病灶),经手术病理证实膀胱移行细胞癌18例。超声造影诊断膀胱癌的敏感性为94.4%(17/18),特异性为100%(7/7),准确性为96.0%(24/25)。结论:超声造影能够实时观察膀胱占位性病变的血流灌注情况,对占位性病变的诊断和鉴别诊断具有较高的临床应用价值。

Objective： To explore the clinical application value of contrast-enhanced ultrasound（CEUS）in bladder occupied lesions. Methods： Twenty-five cases of bladder occupied lesions were examined by CEUS. The perfusion characteristics were observed by CEUS and the results were contrasted with pathology. Results： Seventeen bladder occupied lesions were diagnosed as malignant by CEUS, 18 bladder occupied lesions were confirmed transitional cell carcinoma of bladder by pathology. The sensitivity, specificity and accuracy of CEUS in the diagnosis of bladder cancer were 94. 4%, 100%, 96. 0% respectively. Conclusion： The blood supply of bladder occupied lesions can be observed by CEUS, which showed important clinical application value in the differential diagnosis of bladder occupied lesions.
