Hyperparathyroidism and renal calculi.

Abstract

SUMMARYA case is described of bilateral renal calculi due to hyperparathyroidism in which no skeletal changes were found. A brief survey is given of all similar cases in the literature.The incidence of renal calculi in hyperparathyroidism and, conversely, of hyperparathyroidism in all cases of renal calculi, is discussed.Attention is drawn to the fact that unilateral renal calculi may be due to hyperparathyroidism.In the early stages of the disease, hyperparathyroidism is more liable to produce renal lithiasis than skeletal changes.A brief survey is given of the criteria for diagnosis of hyperparathyroidism.It is suggested that the possibility of hyperparathyroidism should be considered in all cases of multiple renal calculi, whether unilateral or bilateral.
