I had a 2nd kidney transplant 3 years ago due to Polycystic Kidney Disease. Ever since then I have had severe swelling in my abdomen. Of course the docs thought it was my enlarged native kidney. Turns out (much to everyone's surprise) that it is 2 very huge liver cysts. I had percutaneous draining done a year ago after which the cysts refilled within a week. Now I want to have sclerotherapy done in hope of avoiding a roofing surgical procedure. Does anyone have any familiarity with this and can you offer me any advice. What sclerosis agent was used in the procedure?
