We try to remove the stone from left kidney. Today them remove the fluid.We had a fair kindly advice
[|AI|]  Hi Lisa....small size kidney on one side can be present since birth due to poor development of kidney while in the womb. That is totally harmless. This is most likely in your sisters case. Or it can be due to damage to one kidney by repeated infections, or poor blood supply due to narrowed blood vessel supplying that kidney etc. Because she has only one good kidney she has to protect it. So a stone in left good kidney has to be removed before it can cause any damage to it. Having one kidney is harmless...voluntary kidney donors are living normally....she needs to take care not to become overweight....avoid very high protein intake...check BP regularly.
