Subperiosteal resorption was improved completely by the 6 th postoperative month and cortical defect of general bones was reconstructed gradually thereafter.

Changes of bones observed in 13 patients and nephrolithiasis was observed in 2 out of these 13 patients. The remaining 2 patients showed chemical type of the disease and one patient died of hypercalcemic crisis. Ulceration of the alimentary tract or pancreatitis was not observed among these 16 patients.
