Need a little more information...
How did you come to know about these renal cysts? Also, cysts are commonly on the outside of the kidney, and you titled your question "cists IN kidney"... are you sure they're on the inside?
There are procedures for removing cysts, but as I said, we'll need a bit more information regarding how you came to know about them, their location, how big they are, how many you have, 1 or both kidney's, etc, etc.
The more information you can give, the more people will be able to help you.
Your first step is to see a nephrologist.
As you know we're not Drs here. We only give you our opinion based on what we know or experienced.
A neph will better assist you in this journey.
