Clinical Trial Summary

The aim of this study was to show additional diagnostic criteria of computed tomography (CT) scan to diagnose and predict the detection and recurrence of cystic renal cell carcinoma in the patients with complicated renal cysts. Furthermore, we would demonstrate the relationship between complicated renal cysts diagnosed by Bosniak system and some parameters of pathological results. The analysis about detection time of renal malignancy would help determine the practical guidelines of follow-up plan for complicated renal cysts.


Clinical Trial Description

Even though there have been many trials and errors to enhance the diagnostic accuracy of CT scans for complicated cysts, the trial to obtain the enhanced accuracy using CT scan would be still valuable, when we consider its widespread use. A previous study demonstrated that the enhancement of HU with intravenous administration of contrast material on CT scan by 15 HU would be "almost always indicative of a pathologic process although not always a malignancy", another study showed the cut-off as 42 or 47 HU gap would be helpful in the prediction of renal malignancy. ;
