Long-term follow-up study of the malignant transformation potential of the simple renal cysts.

ABSTRACT:

Background

We conducted a multi-center study to investigate the prevalence, the malignant transformation potential of the simple renal cysts and the factors that might predict malignancy.

Methods

We defined the simple renal cysts as Bosniak class I & II (including IIF) lesions. In the prevalence study, data from 115,132 ultrasonographies was collected from individuals who participated in a multiphasic health wellness screen. In the natural history and progression study, we retrospectively reviewed 333 participants with simple renal cysts and were followed for at the least 3 years with a mean of 6.3±2.9 years (ranged from 3 to 13 years).

Results

About 7.2% (8,303) of the individuals who participated in the study were found to have at the least one simple renal cyst. Th
