<bot>: Hi friend, Welcome to Chat Doctor There are cysts on both sides.  The cyst on the left side is small and simple - nothing need be done for it except to repeat the scan after 6 months.  The one on the right side is big and could be complex - it needs further assessment and assistance by a specialist - UROLOGIST.  Earlier, the better.  You may need CT scan, biopsy and so on for a definite diagnosis.  Management will depend on the diagnosis. Take tarnishing speedy recovery God bless Good luck
