I am 78, and am in stage 4 CKD, with a GFR of 28. Which has been fairly stable but in gradual decline. My kidney problem stems from an incident of acute kidney failure associated with an operation for aneurysm of the abdominal aorta. I have had recent tests recommended for a colonoscopy and a nuclear stress test. Both involve prep or injections that seem like they could be dangerous to my kidneys. Prep for the colonoscopy is a prep kit of sodium sulfate, potassium sulfate and magnesium sulfate, with anesthetic of propofol. The stress test involves injections of thallium and cardiolite, both radioactive isotopes. Are these tests likely to put my kidneys under serious stress, and perhaps result in a decline of my GFR?

I suggest that you use a colonoscopy prep that uses polyethylene glycol (PEG) with electrolytes rather than sodium, magnesium and potassium sulfate.  PEG with electrolytes is much safer than the sulfate.  The thallium and the Cardiolite will not result in … Continue reading

My father-in-law was biopsied and found his system was attacking his kidneys and had 6% kidney function, went on dialysis for 3 weeks to see if kidneys would kick start. He did intravenous steroid drip for 3 days & continued steroid pill and still is taking it. The MD at skilled care gave him the choice to continue steroids to feel alert/appetite. He was told dialysis did not improve health and no kidney function. He stopped dialysis on 12/30/2016 and was told he had up to 2 weeks to live. He had no urine output. On 01/05/2017 he started to have abdominal, back & leg edema, if pressure was placed, fluid would seep through the skin. On 01/06/17 he voided clear. He has a great appetite and has BM’s approx every 3 days. Since fluid retention is not getting worse and with releasing toxins, is he improving due to the steroids he is still taking? Should we be contacting his Nephrologist?

I am unable to make a specific diagnosis based on the information that you present.  Your father-in-law will need to consult with a nephrologist to see if he is having return of kidney function or if there is still a … Continue reading

Sometimes I have visible blood in the urine. And my urologist says it’s normal. Is it normal?

If you have been checked by a urologist for gross (visible) bleeding into the urine, then this could be normal.  In most cases, it is a urologist that must examine you and determine if visible blood in the urine represents … Continue reading

Is it dangerous for a right kidney to measure 7cm?

The normal length for a kidney is 10 centimeters (cm) for a woman and 11 cm for a man.  Hence, your right kidney appears to be small for some reason.
