Records of 46 patients who were treated for primary hyperparathyroidism at King Khalid University Hospital, Riyadh Saudi Arabia from 1st July 2000 to 30th June 2006 were reviewed. Mean age at diagnosis was 44 years (range 13-70 years) and average duration of symptoms was 39 months (1 month to 11 years). There were 35 females and 11 males with a ratio of 3.2:1. Bone pains were the major symptoms at presentation in 45.7% followed by no symptom in 23.9%, renal stones in 15.2%, polyuria in 6.5%, while 4.3% each presented with depression, and constipation. Males had significantly more severe disease with higher serum calcium, higher urinary calcium excretion, and higher serum creatinine. Ninety six percent of patients had successful surgery and 4% (two patients) each had recurrence and hungry bone syndrome. It is concluded that PHPT in Saudi Arabia continues to be a symptomatic disorder with skeletal and renal manifestations occurring at a younger age and males having more severe disease. Further prospective studies are needed to verify our findings.
