title: Does inhibition of prostaglandin synthesis increase the diagnostic accuracy of the intravenous urogram in renal artery stenosis?
abstract: Intravenous urography is the standard screening test for renovascular hypertension but there is a significant incidence of false negative and false positive results. In an attempt to improve the detection rate, indomethacin was administered orally to nine patients with renal artery stenosis (proven by arteriography and by divided ureteric function studies) before rapid-series intravenous urography. This urogram was compared independently by two observers with prior similar-series urograms. Indomethacin did not alter diagnostic accuracy.
