1) Find out from your urologist where on the "Bosniak Chart" your cyst is. It's a chart that ranges from 1-4 and let's you know the relative severity of your cyst load/case.
2) Many people go their entire life with a renal cust and never know they even have it.
3) If your urologist offers it as an option, renal cyst-decortication is an option.
I have a constant 3-5 pain level from my cyst load, and it's a pain to deal with (pardon the pun).
Mine came about as a result of 100's of traumatic procedures for stone removal, and being blasted by x-rays, ct's & mri's repeatedly over the last 20 years.
Good luck to you.
