RESUMO
UNLABELLED: Aim of our study is to analyze sensitivity and specificity of imaging procedures in characterization upper urothelial malignancies, according to algorithm suggested by American Urology Association. MATERIAL AND METHODS: We analyzed 242 patients with kidney tumor masses who had been operated during 2006/2007 at Urological clinic in Belgrade. Due to pathohistological exam 210 patients had kidney parenchyma and 32 patients upper urothelial kidney tumor. RESULTS: According to tumor stage, computed tomography was sufficient and definitive diagnostic tool concerning both renal epithelial and upper urothelial malignancy. Only in four cases 1.60% (4/242; CT in 3/4, MRI 1/4) preoperative site of origin was different from histopathology findings. This mislead to inappropriate surgery plan. CONCLUSION: Familiarity with limitations and capabilities of imaging modalities is crucial for appropriate diagnosis. It should respect algorithm but has to be individual adapted.
