There are several ways to manage bone health when someone has kidney disease or kidney failure. Surgery is considered a last option when diet, medication and more dialysis haven't helped. Have you tried those other ways to manage your calcium, phosphorus, and PTH? The National Kidney Foundation has information on secondary parathyroidism (secondary means the parathyroidism is due to another condition, like kidney disease).
There are 4 parathyroids. I have known some patients who had most of their parathyroid glands removed from their neck and placed under the skin in their arm. Calcium levels can fall after this surgery so it's important for the doctor to monitor and treat as needed. I found this patient education site describing the surgery. It's written at a higher level than I'd like to see, but may give you some questions to ask your doctor and/or surgeon. http://endocrinediseases.org/parathyroid/surgery_overview.shtml
