Hypertension is a common complication observed after renal transplantation. If the hypertension is of renovascular origin, transluminal angioplasty or surgery of the renal artery stenosis can lead help cure the hypertension. The blood pressure of a 31-year-old man who underwent renal transplantation 2 years earlier gradually increased. Arteriography showed stenosis (>80%) in the two branches of the renal artery. To help confirm the presence of renovascular hypertension, captopril renography was performed but showed no significant changes compared with baseline renography. Renography was performed again after losartan administration and showed impaired renal function. In this case, losartan renography was more useful than captopril in suggesting renovascular hypertension.
高血压是肾移植后常见的并发症。如果高血压源于肾血管，经腔血管成形术或肾动脉狭窄手术有助于治愈高血压。一名31岁男性在两年前接受了肾移植，其血压逐渐升高。血管造影显示肾动脉的两个分支存在狭窄（>80%）。为了帮助确认肾血管性高血压的存在，进行了卡托普利肾图检查，但与基线肾图相比无明显变化。服用氯沙坦后再次进行肾图检查，结果显示肾功能受损。在这种情况下，氯沙坦肾图在提示肾血管性高血压方面比卡托普利更有用。
