Is There an Increased Incidence of Renal Stone Disease?
) Objective: Parathyroid adenomas cause hypercalcemia and are culprits in the development of renal stone disease. With serum assays available, early detection of parathyroid tumors is possible. We questioned if the incidence of nephrocalcinosis and urolithiasis was still increased compared to the normal population in view of the early detection of parathyroid adenomas. Materials and Methods: We retrospectively reviewed the renal ultrasounds of 271 surgically-proven parathyroid adenomas. Each had a renal imaging study performed within six months of surgery. Our control group consisted of renal ultrasounds performed for various reasons in an age-matched population. Results: The parathyroidectomy patients had renal stones noted in 18 cases (18/271 = 6.6%). Our control group had stones detected in 22 cases (22/340 = 6.5%). Conclusion: We did not note an increased incidence of renal stone disease in patients with surgically proven hyperparathyroidism. We propose that the very early and aggr
