Some people go their entire life without ever knowing they have a renal cyst. You were scanned, and now you know.
Is it causing you any discomfort? Some cysts do cause flank/pelvic discomfort, is the reason I ask.
Have a urologist read your scan results and tell you where on the Bosniak Chart your cysts fall, and g from there. "Simple Cysts" they'll usually just leave and re-scan in several years to check on progress. "Complex Cysts" (higher than a 2F Bosniak) they might want to take a second look at.
If they operate, there are a number of options, the easiest (in my humble user-level opinion) is a cyst-decortication. They basically slice off the top of the cysts, drain the fluid, and cauterize the lesion. Recurrence is marginal, but it's better than nothing! Surgery itself is a piece of cake. The recovery is interesting. I'll tell you about it if you decide on the decortication option.
