[Importance and reliability of preoperative localization in primary hyperparathyroidism].

On the basis of experience with a group of 176 performed operations for primary hyperparathyreosis at the 3rd Surgical Clinic of 1st Medical Faculty of Charles University in Prague in cooperation with the 3rd Internal Clinic of 1st Medical Faculty of Charles University in Prague, we together share the opinion to perform necessary preoperative localization examinations. Sonography is routinely performed and after evaluation of its objective result scintigraphy and MRI is individually indicated. Preoperative localization of adenomas shortens the time of operative procedure. Sufficient experience with preoperative localization examinations become more important especially in the diagnosis before reoperations of parathyroidal adenomas which are sometimes necessary.
