ARF on CKD. Or kidney transplant?

Dear Doc, My father was initially diagnosed for low Hb. After treatment from local Drs didn't improve his condition, we consulted a Physician who advised further test where in his Creatine level was found to be 6.33. He immediately asked for meeting with a Nephrologist. The Nephrologist advised a USG where in it's revealed that there is Polycystic Kidney Disease, Hepatomegaly. My fathers BP is 130/80 and Sugar is below 110. There is no edema or any other symptom. Ethropoetin 10k and Hepatitis vaccine have been adminstered to my dad. The Nephrologist has advised 10 day Levoday course and advised to stop all other medication as he wants to see drop in Creatine level based on which he will suggest line of action. Is there a cure for Polycystic Kidney. Will my dad require Dialysis or Kidney transplant?
