[|Human|] I only have one kidney, but that kidney has an 11cm cyst on it. My urologist thinks we need to leave it alone for risk of damaging it during aspiration. It has grown 2 cm in 9 months. Do you feel like this is the right decision. How much would an 11 cm simple cyst weigh and could this be why my abdomin has gotten so big and I cant loose weight?
[|AI|]  Hi, Thanks for writing in to us. An 11 cm cyst in the kidney is relatively big. Kidney cysts in that range need to be completely evaluated by CT or MRI scan to know if it is a simple cyst or has any complex feature within. I would suggest that you get a second opinion from another urologist for your condition as you have only a single kidney. The cyst can weigh over 700 grams if it contains fluid, it can weigh more if solid areas are there. Hope this helps
