[The radionuclide diagnosis of vasorenal hypertension using an angiotensin-converting enzyme inhibitor].

Conventional routine renography and dynamic renoscintigraphy fail to yield sufficient diagnostic criteria in vasorenal hypertension, being associated with 21.5% false negative and 33.3% false positive results. Capoten induces statistically significant functional changes manifested by worsening of time-associated indicators of secretory-excretory function of the kidney, glomerular filtration rate and effective renal plasma flow on the side of the unilateral renal artery stenosis; relative hypotension in this situation leads to a statistically insignificant improvement of functional activity of the contralateral kidney parenchyma.
