【摘要】 用巯甲丙脯酸运动肾显像（Ｃａｐ－Ｅｘ－ＲＳ）观察２９例正常人及５６例原发性高血压（ＥＨ）的肾功能。结果显示ＢＵＮ及Ｓｃｒ正常的ＥＨ患者其基础肾显像（ＢＳＬ）的全肾平均通过时间（ＫＭＴＴ）及高峰时间（ＴＰ）比正常人明显延长（Ｐ＜０．０１），不变（Ｎ）及缩短（Ｓ）组的介入ＫＭＴＴ比正常人明显缩短（Ｐ＜０．０５），延长（Ｐ）、Ｎ、Ｓ三组间差异显著。表明Ｃａｐ－Ｅｘ－ＲＳ是一灵敏的评价ＥＨ早期肾功能改变的方法，可对ＥＨ进行分组并指导治疗。该法简单、灵敏、准确、重复性好，是集总肾及分肾功能与形态为一体的功能、影像诊断方法。更多还原

【Abstract】 he renal function was evaluated in 29 normalsubjects and 56 patients with essential hypertension(EH) in Captopril-exercise renal scintigraphy (Cap-Ex-RS). The results showed that the whole kidneymean transit time (KMTT) and the time of peak (TP)of BSL in patients with EH whose BUN and Scr werenormal were significantly prolonged and the KMTT ofintervention in N and S groups was significantly re-duced than that of the normal subjects. There weresignificant differences among 3 EH groups. Our datademonstrated that the Cap-Ex-RS was a sensitivemethod for detecting the early impairment of renalfunction in patients with EH. This method can also beused for classification of EH and guiding treatment ofEH. It is not only a simpie and reliable method for de-tecting split renal function but an image of both kid-neys and urinary tracts.更多还原
