The purpose of this study was to evaluate the accuracy and reliability of duplex Doppler ultrasound (US) and computerized tomography (CT) in staging patients with renal cell carcinoma (RCC). Sixty-six patients were evaluated pre-operatively with duplex Doppler ultrasound and CT. The results were compared with the surgical and histopathological findings. T stage was determined correctly with duplex Doppler US and CT in 56 and 50 cases respectively. In 4 patients with nodal disease duplex Doppler US was correct in 2 patients, 1 was false positive. With CT, 3 patients were staged correctly and 3 were false positive. Of the 14 patients with vascular tumour thrombi, 13 were staged correctly with duplex Doppler US and 12 with CT scan. False positive vascular tumour invasion was seen only with CT in 4 cases. Based on these results we conclude that duplex Doppler US is at least as accurate as CT scanning in the staging of RCC. Also in patients with renal or caval thrombi, duplex Doppler US is highly accurate in establishing the diagnosis and in the determination of the extent of the thrombus.
本研究的目的是评估双功多普勒超声（US）和计算机断层扫描（CT）在肾细胞癌（RCC）患者分期中的准确性和可靠性。对66例患者进行了术前双功多普勒超声和CT评估。将结果与手术及组织病理学结果进行比较。双功多普勒超声和CT分别在56例和50例中正确确定了T分期。在4例有淋巴结疾病的患者中，双功多普勒超声在2例中判断正确，1例假阳性。CT在3例中分期正确，3例假阳性。在14例有血管肿瘤血栓的患者中，双功多普勒超声正确分期13例，CT扫描正确分期12例。仅CT发现4例假阳性血管肿瘤侵犯。基于这些结果，我们得出结论，双功多普勒超声在RCC分期中至少与CT扫描一样准确。在有肾或腔静脉血栓的患者中，双功多普勒超声在确立诊断和确定血栓范围方面也高度准确。
