isotope scan



Should someone with eGFR 16 then a few days later 19, be having a Nuclear Renogram?

Thank you.

HI Mary, If it is the dye you are worried about, you should ask your doctor. Other wise the test is not going to affect your kidneys. I am about to have one and I have a lower GFR. It is part of the transplant regiment for evaluation. So I think it must be ok.

Hi Bassetmommer

Thank you so much for your reply.

He had one just five months ago. He then had a Nephrostomy and uretral stent fitted three months later which was supposed to be curative but has not been (to treat single Hydronephrosis of eleven month). Worse symptoms, higher Creatinine and lower eGFR. Very low Iron and low transferrin Saturation Rate. Low Sodium (which is recovering but still below normal range,)

I called the same Kidney helpline on two different occasions and had two different reactions. The first person thought it would be helpful in revealing what is happening. The second person was shocked to hear such low Kidney Function and not yet been seen by a Nephrologist. Seemed to think the iodine would be more work for kidneys functioning at just 16 to 19 %. Might do more damage ??

I just wondered if there should be some after care/treatment such as a drip?

Thanks again for replying.

HI Mary Yes, he needs to see a nephrologist. We are not doctors and any treatment would have to come from a professional.

Sorry Bassetmommer (so much history -as been going on for a year)

Yes, he does have an appointment (long overdue I think!) in the near future with a Nephrologist but only because I wrote to the Secretary.

Thanks again

The iodine contrast used in a variety of scans can create temporary to permanent kidney damage for some people. Simply mention your kidney concerns to the person in charge of the scan and s/he will likely reduce the amount of iodine infused or use another type of contrast. In my husband's case, he needed to have a heart catherization and the amount of iodine used was reduced after he presented his concerns the day he came in to have it done. Although my husband is on dialysis, he still retains some kidney function. Following the procedure, his kidneys continue to perform as usual.

Thank you Darlenia. This is very helpful.


It wasn't Iodine.

Hi again Just a thought- you will be on dialysis though?

I personally do not accept any medication, procedure, or test without knowing any and all risks to my kidneys. All side effects and expected outcomes should be explained to you fully so you can make an informed decision. If you have Nephrologist it would be best to ask them.
