Abstract:
The incidence of primary hyperparathyroidism was determined in 4000 renal stone formers treated by ESWL at our institution from 1983 to 1990. Based on repeated measurements of serum calcium and serum parathyroid hormone an incidence of 2.8% was found. In 60% of patients with primary hyperparathyroidism stone disease occurred for the first time. The majority of patients (68%) were more than 50 years of age. 56% of patients were men, 44% were women.
