目的本文旨在确定卡托普利-肾图诊断骨动脉狭窄的敏感性、特异性和临床价值。病人和方法 55例疑及肾动脉狭窄者于肾血管造影前作卡托普利-肾图。连续二天用~(99m)锝二乙三胺工乙酸(DTPA)测定肾小球滤过率,以~(131)碘邻马尿酸(OIH)测定肾血流量。于第二次测定前一小时口服压碎的卡托普利片剂25mg。肾动脉造影显示狭窄>70％者可确诊为肾动脉狭窄。再回顾性地建立鉴别肾动脉狭窄和原发性高血压的肾图标准:(1)两侧功能不对称;(2)出现卡托普利所致改变。结果 55例患者中35例肾动脉狭窄(21例单侧,14例双侧)。标准有三:(1)患侧
Purpose This study aimed to determine the sensitivity, specificity and clinical value of captopril-nephrin in the diagnosis of bone stenosis. Patients and Methods 55 cases of suspected renal artery stenosis before renovascular angiography captopril - renal diagram. Glomerular filtration rate (GFR) was measured with ~ (99m) technetium diepiperazinetriamineacetic acid (DTPA) for two consecutive days, and renal blood flow was measured with ~ (131) iodine o-hippuric acid (OIH) 25 mg of captopril tablets were orally crushed one hour before the second test. Renal artery angiography showed stenosis> 70% can be diagnosed as renal artery stenosis. Retrospectively to establish identification of renal artery stenosis and essential hypertension nephogram standard: (1) asymmetric function on both sides; (2) appear captopril-induced changes. Results Of the 55 patients, 35 had stenosis of the renal artery (21 unilateral and 14 bilateral). There are three standards: (1) ipsilateral
