title: Uroliathiasis with primary hyperparathyroidism. A one-year screening.
abstract: A one-year material of 290 patients with clinically verified urolithiasis was screened for primary hyperparthyroidism, by X-ray examination, analysis of calculi, plasma calcium and phosphate, plasma parathyroid hormone and a clinical history examination. Primary hyperparathyroidism was found in 10 patients, 8 with adenomas and 2 with hyperplasia. The results suggest that with the present policy of investigation, there is a considerable underdiagnosis of parathyroid changes in patients with urolithiasis. An interesting finding was the distribution of plasma calcium concentrations in this material, which indicates that patients with urolithiasis have a generally higher lever of plasma calcium than others.
