Hi I have wanted to donate a kidney for years. I was diagnosed with stage 1B squamous cell lung cancer in 2012. The left upper lobe was removed and I had one dose of chemo which almost killed me. It will be 5 years on Aug 20 2017. Can I donate a kidney or is it to risky? My age is 58 yr old female otherwise in decent health.

It is unlikely that you could be a kidney donor with a history of lung cancer.  It is your right to offer to donate, and each and every transplant center determines who can and cannot be a kidney donor.  There … Continue reading

My brother is awaiting a second kidney transplant. His first transplant was 7 years back. Dr’s are saying his PRA levels are very high. He has HLA Class I PRA -7% and HLA Class II PRA -91% (tests done in Feb 2017) What are options to reduce PRA and can continuous dialysis for some more time reduce PRA? He started dialysis again in Feb this year and he had few blood transfusions in Jan & feb this year.

Panel reactive antibodies (PRA’s) are immune proteins in the blood that are non-specifically directed against potential kidney donors.  In some cases, the exact Human Lymphocyte Antigen (HLA) type can be detected, but in some cases, we do not know the … Continue reading

My question is out of desperation. My husband has suffered kidney issues since he was 12. And at the age of 35 and after many kidney surgeries and procedures had his left kidney removed. It was not draining correctly causing severe pain and after several attempts to repair it, the doctors decided removing it was the best option. Now he is having similar problems with his other kidney. After research of my own, I went to the local urologist here and told him I thought my husband had a floating kidney. He said he had never heard of that but thought it made sense. He did all the tests and said, yes, that his kidney was moving and that was what was causing the pain and why it was not draining. He said he would look into the surgery and put in a stent for the time being. When we went to the followup, we were treated much different. We were told that floating kidney was not real and they would not do the surgery and all they would do is put in stents. I guess my question is, how can a Doctor say something he can see with a test is not real and where do I go from here for treatment. There is a surgery out there that can fix this but instead my husband is forced to suffer and live a life in pain.

I have never heard of a floating kidney.  I understand that this term used to be used years ago to describe pain moving around in the back, but the kidney only moves up and down when you breathe.  Everyone’s kidneys … Continue reading

What is the best solution to use for a cleanse before a colon exam?

Before a colon examination, such as a colonoscopy, I recommend use of laxatives that contain polyethylene glycol plus electrolytes (such brand names as Miralax, Golytely, Nulytely and many others).  I do not recommend Magnesium Citrate or Fleets Phosphasoda.

I have three kidneys. I had a CT scan and they said one of the kidneys was black. What does that mean and what are the risks?

The medical term for multiple kidneys is “supernumerary kidneys”.  This is a congenital condition and means that you were born with extra kidney tissue.  This extra kidney may or may not work properly.  I do not understand the term “black … Continue reading

I am male 82 years old. I tested today for 2.0 creatinine. I have been taking for a long period of time 3mg a day of Ativan and 400 mg of Ibuprofen. Could these medicines affect the creatinine level and if so would it raise them that much? About a year ago, it was less than 1.3 and I have only tested again this year to find the high increase.

Ibuprofen can reduce kidney function and should not be taken long term.  I suspect that the abnormalities in your kidney function may be related to the ibuprofen.  I suggest that you stop this medication and then see your primary care … Continue reading

After a kidney stone removal operation, can the scar be a vertical line – running from the lower rib cage to the navel (belly button)? Can you please provide me with photo’s of – or refer me to where I can download photo’s of the scar(s) a patient could have after such a procedure ? Thank you very much for your time.

I am a nephrologist and not a surgeon.  A urologist performs kidney surgery and I have no expertise in surgery and do not know where different incisions may be made for different surgeries.  I suggest that you ask your urologist … Continue reading
