Can an unblocked yet enlarged kidney cause back pain?

For the past year (April 08 to the present) i've been dealing with a damaged left kidney caused by a crossing artery blocking my ureter.  I had a robotic UPJ obstruction last summer which was successful until October of 2008 when i started to feel left flank pain again.  Last week i had the partial blockage (from a stitch from the original procedure) moved and i currently have a ureteral stent in keeping the ureter open while healing.  I've been told by many urologist i've seen after plenty of renal scans, that the kidney will not regain more function (right now its at 25%) but because the stent is in now it is draining properly.

4 days after my most recent procedure however, i started to feel the same swollen flank pain i had that triggered all this in the first place.  My confusion is that the stent is currently in while my back is hurting. My question is can an unblocked yet severely enlarged kidney cause back pain? I have been told that only a blockage can cause discomfort and you don't feel your kidney only the obstruction to and from your kidney.  My doctor told me if i have back pain with the stent in that it might be other factors (ie pinched nerve, slipped disk) which i find hard to believe because it is the exact swollen, numb and bruised type feeling that helped me realize my kidney problems in the first place.  Help?

Hopefully this makes sense and I've explained it well enough, hope to hear from someone soon on it.

I was looking up "enlarged kidney" because I just found out I've got one, actually two.  Aching and pain were listed as symptoms, which I definitely have.  I'm no doctor, but I think you doc is wrong.

You used the word swollen.  Is the kidney area swollen, or just feels swollen?

I too have an enlarged kidney.  Not real big, but they have put me off for over a year and a half now.

Sometimes stents can cause discomfort. I've never had one, but I have heard they can be very uncomfortable.  Has the dr. offered to do any test to check to see if anything is wrong with the placement of the stent?

Hydronephrosis is the swelling of a kidney due to a build-up of urine. It happens when urine cannot drain out from the kidney to the bladder from a blockage or obstruction. Hydronephrosis can occur in one or both kidneys.    I have just been diagnosed with that and it is my right kidney that is swollen because of an obstruction at the bottom.  The urologist said he  could surgically remove it by laproscopy or becasue of my age, 74, just leave it and see what happens.  I am apprehensive about just leaving in an organ that is no longe functioning and swollen.  Also, what about the urine that is accumulates in there, won't it cause problems.  He more of less said the kidney was dead and didn't offer any thing like a stint etc to see if they could open it up more.  I have multiple spinal issues but most of them are on the left side with pain and weakness.  However, this new pain on the right seems to be more tender and I can feel it when I lie down.  Hope somebody will share some feedback as I am still undeciced whether to just leave it or have it removed by surgery. Thank you.
I’m sorry you are going through so much. I would call your dr and ask if a stent would help allow urine to flow better.
I would get a second opinion just to see if the two opinions diverge.  My guess is, especially given your other problems and your age, that the doc is hoping to avoid any kind of surgery just to be on the safe side.  If the kidney is actually incapable of ever functioning again I can see your point but I'm also always aware that docs really don't know that kind of thing for certain.  Another urologist might also have an idea for how to deal with the obstruction.  You won't know if you don't try.  Sometimes the best thing to do with docs is see a better doc, which might mean going out of your area to somewhere where the best docs are.  Good luck.
