Wang J et al. – This study assessed the variation in urinary calcium levels among fracture patients who underwent surgery, based on fracture type, fracture location, age, and gender. The authors concluded that variation in urinary calcium in these patients was of a regular pattern and hypercalciuria was observed in these patients. Hence, high–calcium diet and calcium supplements should be used carefully in these patients.

Methods

• The enrolled patients (N = 768) were divided into 2 groups; group A (fracture patients who underwent surgery) and group B (normal patients without fracture).
• Urine samples were collected for a 24–hour period (24–hour urine) at several specific time points before and after surgery in group A and following hospitalization in group B.

Results

• Urine calcium levels in group A were significantly increased at different time points during the study period compared with group B.
• Changes in urine calcium levels revealed significant differences according to fracture location, fracture type, and age, but not gender.
• Group A had more patients with hypercalciuria at different time points compared with group B.
