While we wait for others to join the discussion, you may wish to read this information from Mayo Clinic about renal cysts https://www.mayoclinic.org/diseases-conditions/kidney-cysts/diagnosis-treatment/drc-20374138
The article includes questions to ask your doctor. Might these help you get answers to your questions from your urologist and to judge whether or not to get a second opinion?
