What tests do patients need to have before surgery? Parathyroidectomy is a moderate surgery with technical difficulty level 4 (the highest level). Some basic safety tests such as coagulation index, thyroid and liver function index, heart function test, lung function test, parathyroid localization test and imaging tests including ultrasound and radionuclide are required before surgery. How long does the surgery take approximately? The number and location of the parathyroid glands varies greatly. Normal people have four, but some people have three, five, six, or even seven parathyroid glands reported to grow, and the exact location varies. The procedure takes about an hour, plus anesthesia, about an hour and a half in total. However, in rare cases, the procedure may take longer for more difficult patients. How long does it take for a patient to recover? Patients are usually hospitalized for about five to seven days (not including preoperative testing) and are discharged after the severe postoperative hypocalcemia period. However, some patients maintain the low calcium period for a longer period, some for about a month. In this case, if the patient has severe low calcium after discharge, he or she can return to the local hospital to continue the calcium supplementation treatment and we will also give an appropriate treatment plan. The cost is about 20,000 to 30,000, including tests, medication, surgery, anesthesia, hospitalization and dialysis. If the patient is in relatively good physical condition, 20,000 will be enough. But some patients have very poor heart and lung function and may also need treatment for heart failure and enhanced dialysis before surgery, in which case the cost will be a little more. But these costs are basically covered by medical insurance reimbursement.
