[Clinical evidence and treatment for optimum concentration of parathyroid hormone, calcium and phosphate in chronic renal failure].

: Hyperparathyroidism, renal osteodystrophy and ectopic calcification, caused by hypocalcemia and hyperphosphatemia, are important complication in renal dysfunction, especially in end stage renal disease. Because it is the reason for reducing the survival rate and quality of life in these patients, it is important to control them from early stage in renal dysfunction. K/DOQI (kidney disease outcomes quality initiative) guideline shows us the recommended practical level and its account. It may be helpful for our daily clinical work.
