Hi and thank you for using health care Magic.
Cysts in the kidneys are commonly found in people as we age. The finding of a few simple cysts on a ultrasound
in and of itself would not warrant further evaluation. The findings of a cyst that would warrant further evaluation would be large size (right around where his are or greater), complexity of the cyst by imaging which would indicate that it is not just fluid-filled or any masslike characteristics. If the original imaging was done in May 2011 and there has been no change in the size, it would seem unlikely to be of any significance. To reassure yourself, I would suggest that you request an MRI
to further characterize the cyst as well as urine cytology
. Benign findings on an MRI and negative urine cytology would be highly reassuring without the need for further extensive workup.
