Optimizing work-up of adult hypertensive patients for renal artery stenosis. Observations about hypertensive urography, digital subtraction arteriography, and patient selection.

To optimize the use of digital subtraction arteriography in the evaluation of hypertensive patients, the use of this diagnostic test should be linked to the treatment choice of surgery. To accomplish this, the patient selection criteria for digital arteriography should be the same as those used to select patients for surgical correction of renal artery stenosis with a high likelihood of surgical cure.
