Differential diagnosis of atypical renal cysts and renal cell carcinoma remains difficult. We analyzed the accuracy of currents methods of visual diagnosis (US, CT, MRT and cyst puncture) in this patients. Surgical exploration was performed in 15 patients. The pathological specimens were compared retrospectively with results of different methods of diagnostics. The classification of Bosniak was used. From all 15 lesions 47,7% proved to be malignant. Our results suggest that radiolodical techniques are not well suites for differentiation of cystics masses Bosniak II and III. Accuracy and specifity of cyst puncture was 71,4% and 77,8%. Mean type of treatment is nephron-sparing surgery. The features of progression of tumor at follow-up 42 months are not fixed.
