title: [Two cases of primary hyperparathyroidism].
abstract: Two cases of primary hyperparathyroidism with urolithiasis are reported. These cases were preoperatively localized by CT-scan and 201T1-chloride scintiscan. Primary hyperparathyroidism is one of the most significant pathogenesis of urolithiasis and determination of serum Ca level is valuable in screening for primary hyperparathyroidism. CT-scan, ultrasonogram and scintiscan with 201T1-chloride are useful and are non-invasive studies to detect preoperative localization of parathyroid tumors.
