This is for my husband, 58 years old. Last year, June, his serum creatinine was 1.23 and GFR WAS 65. This week tested it was 1.4 and GFR 55. He has high blood pressure. Fasting sugar 111. Prostate enlargement. Yesterday, consulted a doctor and suggested calcitriol 0.25, temulose and minnamineforte. Let me know is it safe taking calcitriol or not. I fear it may cause any adverse condition.

Calcitriol is an active form of vitamin D and is commonly used in the treatment of bone disease and secondary hyperparathyroidism in patients with chronic kidney disease (CKD). I am unable to recommend specific medical treatment without performing a complete … Continue reading

I have nausea and urge to throw up, associated with left side kidney pain that radiates to the front lower abdomen. I have had these episodes come and go throughout a time frame of 2-3 years. I recently also took a hard fall off of a bike, and came home in pain worse then I’ve ever felt before on my left kidney. I noticed a few drops of blood in iron. I am worried. Please, any advice of what you think it might be? I truly would appreciate it. Thank you.

I am unable to make a specific diagnosis based on the information that you present.  Further testing will likely be necessary in order to determine the cause of your discomfort.  A complete history and physical examination by your physician should … Continue reading

I am a 76-year-old white male. A year ago I had an eGFR of 45 mL/min/1.73m2 and a P/C ratio of 9,600 mg/g. After taking Valsartan 80 mg once a day since then, my current eGFR is 46 and P/C ratio is 1,080 which is a radical drop in my P/C ratio. All other things being equal, is my prognosis the same as another person who has a P/C ratio of 1,080 without taking Valsartan 80 mg once a day?

I don’t know any way to answer your question because there has been no study comparing people with and without an angiotensin receptor blocker (ARB) agent such as Valsartan who have had a response to Valsartan in the first place. … Continue reading

My father has Stage 4 kidney disease as a result of all the NSAID’s taken prior to hip replacement surgery. Currently his BPH is acting up and he is unable to empty his bladder. A catheter has finally been inserted. We cannot get an appointment with a Urologist until 3 weeks from now. His legs are swollen. How concerned should we be about his kidneys?

Blockage of the bladder can cause worsening of his underlying chronic kidney disease (CKD).  His physician should be monitoring your father’s kidney function with blood testing.

I donated a kidney in 2014, have started to have pain where the missing kidney was, left side. Normal or not. Just trying to save a trip to Dr. office, money is funny for me right now.

I am a nephrologist and not a surgeon.  I have very little experience with kidney donors after they donate a kidney.  I have not heard of late pain after kidney donation.  I suggest you consult with your physician for an … Continue reading

Hello, I have CKD stage 3, microscopic blood in urine. My urologist ordered CT scan w/o contrast and then mentioned maybe a cytology in which contrast would be used. He did not seem concerned about using contrast. Just a bit concerned myself. What are your thoughts please?

If contrast is to be used for a computerized tomogram (CT) scan, the risks and benefits of the contrast should be discussed with you. I do not know anything about the use of contrast for “cytology”.  This does not make … Continue reading

My 72 yr old husband went to ER 8/31/19 for severe back pain, suspected kidney stone. Scans did not show a kidney stone and they thought he had passed it. Blood tests performed at that time showed Serum Creatinine 1.41; Blood Urea Nitrogen 22; MDRD GFR calculated for over 70 years of age was 1.41. Blood tests one month later on 09/30/19 showed Creatinine 1.91; Blood Urea Nitrogen 31; and MDRD GFR calculated 37. Still having back pain and saw Urologist on 10/09/19 who did an X-Ray and ultrasound and found no kidney stone. Blood tests that day were Creatinine 1.89, Blood Urea Nitrogen 37; and MDRD GFR 1.89. With the numbers on these blood tests, I wonder if he should see a kidney specialist. Another symptom (I don’t know if it’s related to the kidneys) is he has had swelling in his groin and legs the last few months and has a red rash on his legs. Swelling is now down to his feet. No one seems to know reason for the swelling. What are your thoughts?

I am unable to make a specific diagnosis based on the information that you present.  Back pain is an uncommon way for kidney disease to present.  It is possible that this represents some form of kidney disease, but I cannot … Continue reading

I’m a SLE patient. I’ve been having trouble with edema (especially in my legs), high blood pressure, and weight gain. My gfr was 70 in March it dropped to 55 in August. My creatinine was 1.1 in March. Should I be concerned about nephritis?

Patients with systemic lupus erythematosus (SLE) can get lupus nephritis and should be monitored for kidney disease.  I would recommend that you have both blood and urine testing for kidney disease.  I recommend that you review this with your physician

Mild fullness of left renal pelvicalyceal system. Is it a serious problem? Kindly suggest some remedy.

I do not know what this means.  It depends on whether this was done with ultrasound, computerized tomography or magnetic resonance imaging.  I suggest that you ask the person who performed the scan to interpret this for you.  The pelvicalyseal … Continue reading

I have a question on all my urine results which has been about 6 urine tests. All show blood in urine. Mostly says small, one shows large. Also on my urine tests, my gravity is all at 1.010 consistency. Is this normal? I have this for 7 months now.

It is never normal to find blood in the urine.  Your urine should be examined under a microscope to determine is red blood cells are actually present.  If you have red blood cells in your urine, then you require further … Continue reading
