IVP screening risks high false positives, costs, and mortality; leaves open whether refined selection improves outcomes in renovascular hypertension.
What is the diagnostic accuracy and cost-effectiveness of intravenous pyelogram and iodohippuran renogram for renovascular hypertension?
Screening for and surgically treating renovascular hypertension is associated with high false-positive rates, significant surgical mortality, and massive population-level costs estimated at 10 to 13 billion dollars for the American population.
McNeil et al. (1975) studied this question.
