Renal cyst aspirated before-larger and more painful this time-Who can help?

Hi, I had a 14cms Renal Cyst aspirated which filled up again within six months. I had the operation again but this time following the draining of the cyst it was filled with a 95% alcohol. This was then drained off. I have had no further problems since. Hi, I had a 14cms Renal Cyst aspirated which filled up again within six months.
