Technetium-99m DTPA renograms were performed before and after angioplasty in a 63-year-old man with bilateral renal artery stenosis (RAS), hypertension, and renal insufficiency. Decreased isotope uptake after captopril by the right kidney assisted in the selection of the right renal artery for angioplasty. Post-angioplasty improvement in both blood pressure control and renal function was accompanied by an absence of effect of captopril on the isotope uptake by the right kidney. In bilateral RAS, the captopril renogram is a useful tool for selecting the site for angioplasty, for assessing the adequacy of the procedure, and for long-term follow-up.
