PURPOSE: Accurate imaging is essential for correct operative planning and successful surgical intervention in renal cell carcinoma (RCC). Our objective was the comparison of color duplex sonography with spiral computed tomography (CT) and surgical-pathological findings in the evaluation of renal masses to determine tumor localization, size, tumor thrombus extent and lymph node metastases. METHODS: We evaluated 60 patients with a renal mass in a prospective study. Both color duplex sonography and CT were performed by different investigators without knowledge of the supposed diagnosis. The color Doppler findings were compared to CT and surgical pathological findings. RESULTS: The sensitivity of color duplex sonography in the detection of RCC and lymph node metastases is comparable to that of CT (100%). Color duplex sonography was superior in the detection of renal vein involvement. Color duplex sonography alone allowed correct planning of the surgical procedure without intraoperative changes in all patients. CONCLUSION: Duplex sonography provides exactly the same information as CT. Although duplex sonography is less expensive with lower exposure to radiation, most surgeons will still probably demand CT for diagnosis, especially as this method is unerring and duplex sonography highly depends on the expertise of the person using it. |
