Report of 9 cases of primary hyperporathyroidism with urolithiasis-literature review

Abstract

Objective To investigate the diagnosis and treatment of primary hyperparathyroidism (PHPT) with urolithiasis.Methods The clinical data of 9 PHPT patients who were evaluated with simple metabolic evaluation in 881 urolithiasis from 2000 to 2005 were summarized and the references were reviewed.Results The level of serum calcium was (2.96±0.48)mmol/L before operation, (1.94±0.42) mmol/L after operation.The level of parathyroid hormone(PTH) was(1133.53±788.21)pmol/L before op-eration,(74.52±49.17)pmol/L after operation.The level of serum calcium and PTH changed significantly after the parathyroidectomy (P<0.01).Follow-up for 14 months to 6 years.the ureteral stones fragments with lithotripsy were clear after 3 months and followed without recurrence,although the renal stones without lithotripsy were followed with no significant change.Conclusions Increase of serum calcium or increase of PTH above double with normal serum calcium may be helpful for diagnosis of PHPT with urolithiasis.Ureteral stone with PHPT should be treated together.Renal stone with PHPT may be followed up after the parathv-roidectomy,and be treated until the complications were occurred.It suggests that the maidend diagnosed pa-tient with urolithiasis should be added with simple metabolic evaluation,including serum calcium, phospho-nium and PTH.
