Abstract:
Purpose:To clarify the association between renal cysts and renal cell carcinoma (RCC), we analyzed the clinical characteristics of patients with renal cell carcinoma and renal cyst. Methods:From May 1996 to January 2004, a total of 198 patients were hospitalized for renal cell carcinoma in our department, and 64 patients had both renal cysts and renal cell carcinoma (RCC). The clinical characteristics of the 64 patients were evaluated, and compared to 106 renal cell carcinoma (RCC)patients without renal cysts from the 198 patients in the same period. Results:Renal cysts were identified by preoperative ultrasonography, computerized tomography and magnetic resonance imaging in 37%(22/59)、24%(15/61) and 35%(6/17) respectively. Histopathological examination revealed renal cyst in 15 patients (23%). The sizes of renal cyst were 0.5 to 12 cm. The pathological examinations showed clear cell carcinoma in 61, chromophilic cell carcinoma in 2 and a combined type of clear cell carcinoma and chromophilic cell carcinoma in 1. Compared to RCC patients with those without renal cyst,younger and male RCC patients were easier to also have with renal cyst(P
