 Background: Primary hyperparathyroidism is autonomous production of parathyroid hormone. After removal of adenoma, one of the surgeons concern is postoperative hypocalcaemia. There is no precise method to determine if patients have hypocalcaemia postoperatively. The purpose of this study was to determine the relation between parathyroid adenoma weights, postoperative serum calcium and serum biochemical parameters in patients with primary hyperparathyroidism.

 Methods: In a prospective study, eighty patients with single parathyroid adenoma were enrolled. Preoperative serum levels of calcium, phosphate, PTH, as well as Postoperative serum calcium and weight of adenomas were recorded. The level of significance was set to be p < 0.05.

 Results: There was no significant correlation between postoperative serum calcium, parathyroid adenoma weight (r= -0.17, p= 0.1), and parathyroid hormone level (r = -0.11, p = 0.3). However, a weak correlation between postoperative and preoperative serum calcium levels (r = 0.23, p = 0.03) was observed. Moreover, Serum calcium decline after adenoma resection was statistically correlated with adenoma weight (r = 0.36, p= 0.001), preoperative serum calcium (r = 0.92, p= 0.0007), PTH (r= 0.54, p= 0.0005) and ALP levels (r = 0.3, p= 0.006).

 Conclusion: Although preoperative serum markers and adenoma weight are unreliable in predicting postoperative serum calcium level, it is possible to estimate postoperative calcium decline by considering adenoma weight and preoperative serum biochemical parameters.
