Re: Question (hypertension)
I was diagnosed 3 years ago with renal artery stenosis after having doppler study, then apparently what you call a renal scan (in nuclear medicine), &
finally renal angiography of arteriogram ( cath is inserted in artery in leg by radiologist). The first test (doppler) indicated one kidney was much smaller than
other (and believe I was told a difference in size of 3 cm or more indicates a
problem which was probably contributing to the BP problem I was having)..
During the arteriogram, the actual size of the kidney was measured and also
a sample of the "renin hormone" the kidney produces was taken.. Two of my
doctors explained in layman's terms that when the kidney is non-functioning or
less than it needs to, the bad kidney produces excess amounts of this hormone in an effort to make the kidney function better, and this hormone
causes the BP to elevate uncontrollably..
If there is partial blockage there, a stent can be inserted
for better blood flow thru the renal artery.. If not as in my case, if the artery is totally blocked, the meds I am given (primarily Ace inhibitors) control this
hormone better than the meds I was on for years which were not controlling
the BP at all apparently ..
Also, the renal doctor checks all the blood levels as well as kidney function
blood levels every few months, and is really my best advisor as to what drugs, even OTC meds to avoid that are hard on the kidneys.. There are lots one has
to avoid if a problem is suspected..
Hope your nephrologist is as thorough as mine has been..
