[Indications of parathyroidectomy for bone disease associated with secondary hyperparathyroidism].

BACKGROUND The indications and suitable operative time of parathyroidectomy for secondary hyperparathyroidism were discussed. METHODS From October 1978 to September 1994 parathyroidectomy was performed for 71 patients who had bone and/or joint pain due to secondary hyperparathyroidism. There were 37 men and 34 women (mean age 48.4 years). The duration of dialysis treatment before parathyroidectomy was 0.8 to 19 years, with a mean of 10.9 years. RESULTS Postoperative subjective improvement was noted in 69% of the patients. No significant difference was observed between the improved and non-improved groups regarding age and the duration of dialysis treatment. But the improvement rate in female patients was significantly lower than that in male patients. CONCLUSION Patients with high carboxyl-terminal PTH level and generalized fibrous osteitis were good suitable objects for parathyroidectomy. But, those with high serum aluminum level were unsuitable objects for it. Furthermore, 99mTc-Pyrophosphate bone scintigraphy and bone mineral determination using dual photon absorptiometry (DPA) or dual energy X-ray absorptiometry (DEXA) were proved to be valuable for patient selection for parathyroidectomy.
