HelloYour findings suggests a small left renal cyst. These are generally age related developmental findings. Simple renal cysts usually doesn't require any treatment. It generally only require follow-up ultrasound. Renal cysts may require treatment if there is infection, enlargement of cyst, pain etc. Your doctor has rightly suggested not to worry. There is no need to change diet habit. You should take healthy and nutritious diet. It is good that you are physically so active. Get well soon. Take Care Chat Doctor.
