Re: Low testosterone concentrations and the symptoms of testosterone deficiency according to the androgen deficiency in ageing males (ADAM) and ageing males' symptoms rating scale (AMS) questionnaires

摘要

Purpose: Serum calcium and parathyroid hormone levels are the primary means of evaluating patients for hyperparathyroidism. Whether there are differences in urinary parameters between stone formers with and those without hyperparathyroidism is controversial. In this study we identify urinary parameters that predict primary hyperparathyroidism.Materials and Methods: From 2001 to 2010 a total of 1,190 adult, noncystine stone forming patients underwent urinary metabolic stone evaluation. Of these patients 34 (3%) underwent parathyroidectomy for primary hyperparathyroidism. Urinary parameters were evaluated as predictors of primary hyperparathyroidism. The most accurate combination of serum and urinary tests and their cutoffs were determined.
