Are Septated Cyst In Both Upper Poles And Tiny Cyst With Wall Calcification In The Right Kidney A Reason To Worry?

Dear Doctors, In just 14 months ago my septated cyst in both upper poles : Right side from 13.9 x 13.6mm to 18 x 14mm & Left side from 42 x 43 x 46mm to 58 x 56 x 41mm. Also a tiny cyst with wall calcification was noted in the mid segment of the right kidney which measures 5 x 4mm. Do I have to be alarmed in this ultrasound result? Most of the time my lower back is aching the whole day. What could be done to stop its growth? I m 59.5 years old, happily married w/ 4 kids, male, not a drunkard and non smoker. I did some exercises just at home after I quit the gym activities 10 yrs ago. And I also have undergone a laparoscopic removal of my prostate gland in the mid 2014 due to cancer. My quarterly PSA monitoring result is just normal to an average of just 0.10 only. I will be looking forward and be thankful for any good advise that you can give to me. Yours Truly, IRB of Quezon Cty, Phils.
