Respected Sir, Good Afternoon, can you please state the GFR value of a healthy kidney (of male/female adults)? Please do reply.

The normal estimated glomerular filtration rate (eGFR) for both men and women is between 90 and 120 milliliters per minute per 1.73 meters squared.  This is true for both men and women. The eGFR is normalized to body size and … Continue reading

I am on dialysis. I started about a month ago. My question is why am I sweating so much everynight?

I am not able to provide a specific diagnosis based on the information that you present. Sweating at night is not a normal response to dialysis. There are many causes of night sweats that are not related to dialysis.  I … Continue reading

In 1996, I was found to have hematuria. In 2000, I started experiencing ulcers on my legs diagnosed as the result of leukocytoclastic vasculitis. I should I just go with this? In 2005, I had proteinuria. A few years later I allowed a biopsy of my kidney. Results showed a damaged kidney. Some unidentified autoimmune cause. Only treatment my nephrologist could give me is blood pressure control. Now, I am told peritoneal dialysis is next.

I am not able to establish a specific diagnosis based on the information that you present.  It is possible to have leukocytoclastic vasculitis of the kidney.  It is commonly called Henoch Shonlein vasculitis or purpura (HSP).  It can be an … Continue reading

Hello sir, my mother is suffering from ckd. She was on medication since last 3 yrs but doctors told due to urine infection. Her creatinine level risen very high then doctor told us for dialysis 2 times a week, but she has blood in urine since last 20 days and doctors have given medicines but someone today told me that if there is blood in urine it means I have developed a hole in kidneys and not going to live more. Is it true?

I am not aware of any diagnosis that involves a “hole in the kidney”.  I suggest that your mother may need further testing.  You will need to consult with your mother’s physician for further testing.

My son 12 years, intermittent hematuria with loin/flank pain bilaterally. Pain begins 4-7 and quickly hits 10. The pain can come early and after without hematuria. He has been to 4 hospitals, no diagnosis. Help.

I am an adult nephrologist and do not see children.  I am unable to offer a diagnosis based on the information that you that you present.  I suggest that you consult with a pediatric nephrologist.

Hello Dr, I recently had my blood work come back from a exam and was wondering about my gfr. My Creatinine level is 1.14 and my egfr came back at 83. I’m 35 yrs old and 6’2″ tall and weigh approx 190 lbs. I put that into the calculation as well and my gfr went to 103. Which one is correct? I’m confused on everything I’m finding and all other blood work if fine. I would just like to know which one is correct. Thank you!

They both are correct.  The first estimation is normalized for 1.73 meters squared and your body surface area (BSA) is greater that’s 1.73 meters squared.  In fact, I calculate your BSA to be 2.13 meters squared. Hence, your eGFR is … Continue reading

My kidney function tests have changed dramatically in the past year. My eGFR has gone from 80 to 55 mL/min/1.73m2, creatinine from .75 to 1.02 mg/dL and BUN from 14 to 25 mg/dL. I am a 72 yr old white female, 5ft 4in 128 lbs, do not have diabetes, HBP or any family Hx of CKD. I doubt if this has any thing to do with it but I did have 2 cups of coffee w/cream before the lab work. I have moderate COPD that was diagnosed 5 years ago and use ANORO. My PFT’s have not gotten worse since being diagnosed. In fact they have improved. I do not smoke or drink. I do have severe back problems which restrict my ability to exercise. I take atorvastatin and all cholesterol & triglyceride levels are within normal ranges. My GP did not seem to be very concerned and did not suggest any further testing or action. I myself am very concerned. Should I see a nephrologist due to these dramatic changes over only 12 months, especially since I do not have any of the classic causes for CKD?

I do suggest that you have urine testing for blood, protein and infection. This will help to understand if you qualify for chronic kidney disease (CKD).  In some elderly females, the estimated glomerular filtration rate (eGFR) can be misleading.  I … Continue reading

Confusion on figuring clearance. Kt/V simple but clinics and doctors use many variations (and seem to change methods form year to year). I just want to know (with home hemo) female, 62″, 101 kg, 72 yrs old, running between 90 and 95 L of blood thru system, Pre BUN 25 post 9 or pre 24 post 8. Does this meet needs? Kt/v and URR.

The urea reduction ratio (URR) is calculated by subtracting the Post Dialysis Blood Urea Nitrogen (BUN) from the Pre-dialysis BUN and dividing that number by the Post Dialysis BUN, then multiplying by 100.  In the case you describe your URR … Continue reading

How do you know that you are not consuming too much sodium daily? I believe that you are not to consume more than 1200 grams daily. (Correct me if I am wrong.) Yet they only list sodium in milligrams. I don’t know how to convert milligrams into grams. Also, on products they don’t list phosphorus in ingredients. So how do I know upfront that I am not consuming too much phosphorus? I am a Chronic Kidney Disease Stage 2 patient(but not on dialysis).

The current recommendations by the American Heart Association (AHA) and the Centers for Disease Control and Prevention (CDC) both recommend no more than 2300 milligrams (mg) of sodium per day.  The level that you quote is very high.  There are … Continue reading

Hi Doc, I was just diagnosed with CKD stage 2, no protein in urine. Is it safe to try and get pregnant while in stage 2? What are the risks? Thx!

Stage 2 chronic kidney disease (CKD) implies that your estimated glomerular filtration rate (eGFR) is between 60 and 89 milliliters per minute per 1.73 meters squared and has been so for at least three months and that you have some … Continue reading
