title: The role of routine intravenous urography in patients with primary hyperparathyroidism.
abstract: The plain abdominal radiographs and intravenous urograms of 72 patients with primary hyperparathyroidism were reviewed. Renal tract calcification was detected on plain abdominal radiographs in 27 patients (38%), and intravenous urography revealed no calculi not detected on the plain radiographs. Intravenous urography did, however, show abnormalities not detected on plain abdominal radiographs in 22 patients (37%), but these findings influenced clinical management in only five patients (7%). In these five patients there were indications other than primary hyperparathyroidism for performing an intravenous urogram. Intravenous urography incurs a small risk and should not be performed as a routine investigation in primary hyperparathyroidism.
