Has anyone had a renal artery by-pass and how are you doing now?


Just curious to see how many answers I will get with this question and would like to know how long it has been and how you feel now, and do you know what caused your problem.
----------

I had one in Feb 06....I am still having edema,feel lousy many days,get drained really easy and still bloated..but now can urinate...my was caused by severe allergic reactions to BP meds with dyes & sulfa in them.... allergic reactions affect the kidneys....I had 6 ER visits in 10 months due to the meds I was on & latex exposures
My new cardiologist is doing a blood test to see if it might be a rare tumor that is increasing the chemicals in my body,causing the water retension and sluggish kidneys...he also said depending on the extent of the kidneys artery damage,it may always be like this..it takes a long time for the kidneys to get back to normal...
if you want to chat with me when you have a down day...Best wishes for a total recovery !!!  (+ info)

is rec very different fore a stint fore heart arteries than one fore renal artery steno sis?


It's hard to tell, but I think you're asking about differences between coronary & renal stents.

The basic construction is very similar. We only place renal stents, but the coronaries (I believe) require smaller stents. Also, drug coated stents are used in the heart. There's no proof yet of any benefit in the renals or legs for drug stents.  (+ info)

if the renal artery was restricted causing the blood pressure to drop what would happen to urine production?


In my experience and my dad's when the renal artery is restricted the blood pressure rises because the kidneys keep asking for more blood. If the kidneys are having problems I believe there would be less urine production. The kidneys are responsible for washing our systems out so there could be other problems before you notice a change in urine output. The easiest way to have kidney function tested is a blood test called creatinine. Some medication can cause kidney problems also.  (+ info)

Anyone out there with Renal Artery Stenosis?


I am 33 years old and have developed hypertension. Despite diet and lifestyle changes, my blood pressure keeps escalating. My doctor said it might be Renal Artery Stenosis and he wants to test me for this disease. I've been reading about it online, but would appreciate hearing from someone who has experienced or is experiencing this firsthand.
I have been on lisinopril for the past year.

It is possible that you have renal artery stenosis (RAS), but much more likely that you haven't. Basic iblood tests such as measuring plasma renin activity and aldosterone can support a diagnosis, but can neither confirm it or rule it out. The gold standard test is renal angiography (X rays of the renal arteries after receiving a contrast medium intravenously) or magnetic resonance angiography. The bottom line is that whether you have it or not is irrelevant unless your blood pressure cannot be controlled by medication, or if your kidney function is impaired.

Lisinopril is a perfectly good choice for RAS associated hypertension, and it it is also one of the first choices in the control of high blood pressure for other reasons (ie "essential" hypertension, which accounts for about 90% of all hypertension, and is most likely what you have.)

Hope this helps.  (+ info)
